Next Episode's Coverage

I hope to talk about Bally BASIC and AstroBASIC with Brian in episode #20. This won't be an in-depth look at the BASIC programming language. Rather I will introduce Brian to BASIC on the Astrocade and show him some games and video art that are written for it.

In episode #18 of the Bally Alley Astrocast podcast, the hosts, Chris and Adam, cover two games written in Bally BASIC called "Cross Country Racer" and "Star Wars" by Doug Shaeffer, an amateur Astrocade programmer. These games were archived, along with other programs, by Paul Thacker in February 2022 from an Astrocade collection bought on Ebay by Nate Reeder in January 2022. Paul says, "These seem to me to have been made for personal use rather than with a goal of publication, but there's still some cool stuff in here [...]." Also covered is one piece of feedback and some recent updates to the Bally Alley website."

  • Doug Shaeffer Tapes - The complete tape archive of Doug Shaeffer's Astrocade Tape Collection.
  • "CHRDIS" Articles by Mike Skala - The three-part "CHRDIS" articles describe how to use the Bally Arcade's built-in Character Display routine from within Bally BASIC to create fast graphic displays. First published in the November and December 1982 and February 1983 Arcadian newsletter. Mike Skala says, "I've seen quite a bit of software lately utilizing the Graphic Character Maker, a machine code routine that Arcadian has published in the past year. This allowed us to use a display routine from the on-board ROM and put complex graphics on the screen instantly, rather than a slow series of BOX and LINE commands. The major drawback here was when moving the graphics, erasing and redrawing: it left us with considerable flashing or blinking. If you have been with us for a while, you know that we are continually evolving and improving; the following tutorial is our new generation of screen animation for the Astrocade!"

Next Episode's Coverage

Perhaps "AstroBASIC" will get some coverage in Episode #19. It makes sense, since Astrocast #18 covered two BASIC games. Astrocast #17 was supposed to cover the material in the "AstroBASIC" manual and it was recorded, but it didn't turned out the way I had hoped that it would sound, so the "AstroBASIC" manual overview has been put off until I can cover it with a co-host like Chris, a BASIC programming ninja, or Paul, who has also programmed in BASIC. We will also cover "Outpost 19," an AstroBASIC game by WaveMakers that will fit naturally into an episode that shares its numbering with the game. We also may try to cover a game that was released on cartridge, but that coverage may be bounced to a future episode because "Outpost 19" may be the most involved game written in BASIC on the Astrocade.

In episode #17 of the Bally Alley Astrocast, I play a bit of catch-up to bring the podcast semi-current. I also made this episode to get me back into the podcasting mood. I cover all of the Bally Arcade/Astrocade videos I made in 2020 about the Astrocade and I make brief mentions of the ones about the Atari, Amiga and TI-99/4a computers. I go over all of the updates to the website dating back to February 2020. I list all of the Astrocade games on cartridge and BASIC that have been covered so far in previous episodes. Plus, I talk about the cartridges that still need to be covered in upcoming episodes.

Thanks to "Quinn Tech Retro" on YouTube and Chris++ for inspiring me to make this episode.

That was recorded, but it didn't turned out the way I hoped that it would sound, so the "AstroBASIC" manual overview has been put off until I can cover it with a co-host. Episode #18 will cover a BASIC game and maybe a cartridge game too. Right now, I'll see what sounds interesting to me when I'm ready to record the new episode.

In episode #16 of the Bally Alley Astrocast, Kevin Bunch interviews Andy Guevara. The interview took place Saturday, May 16, 2020. Andy wrote three programs that were released on cartridge for the Bally Arcade/Astrocade. The first cartridge was Machine Language Manager (MLM), released by The Bit Fiddlers in 1982. L&M Software approached Andy due to his machine language skills and a collaboration got underway that produced Ms. Candyman and Sea Devil, which were both released on cartridge in 1983. Andy also wrote some additional software: Chicken and the Goldfish Demo were released on tape, while a few others were released as type-in programs. Mr. Guevara's used an Apple II Plus with a Z80 card which ran the CP/M operating system to write most of his software for the Bally Arcade/Astrocade.

Machine Language Manager (MLM)

  • Machine Language Manager (MLM) is a 2KB cartridge written by Andy Guevara in 1981 for the Bally Arcade/Astrocade. It was released by The Bit Fiddlers in late 1981/early 1982.
  • There is a series of four videos about the MLM. The episodes are called, "Part 1: Overview and Background," "Part 2: How to Use the MLM," "Part 3: Using MLM Example Programs," and "Part 4: Using MLM with the Astrocade MAME Emulation."

  • Machine Language Manager User's Manual - This manual explains how to program in machine language using the "MLM" cartridge. There is also plenty of information that explains how to program the Bally Arcade/Astrocade in general. The complete source code listing for the cartridge is included.
  • Machine Language Manager Programs - Digitally archived Bally Arcade/Astrocade programs that will load with the Machine Language Manager cartridge and the 300-BAUD tape interface.
  • Machine Language Manager - Source Code - This is the Z80 assembly source code the for MLM cartridge in ready to assemble format.

Sea Devil

  • Sea Devil is a 4K third party game. It was released in 1983 by L&M Software. This cartridge was written by Andy Guevara (of The Bit Fiddlers). You are the guardian of a 21st century undersea farm. Not only is this important to the survival of the people on earth, but the company you work for have risked millions on this venture. Zardos, the evil king of a distant planet, needs this food for himself. He has sent android divers with other sea creatures to steal this food. You must destroy the hoard of poachers as quickly as possible because each bit of food (the white abalone on the bottom) they get will cost you bonus score at the end of the screen. Beware, the poachers are releasing undersea mines to destroy you, avoid them by evasive action.

Ms. Candyman

  • Ms. Candyman is a 4K cartridge released by L&M Software in 1983. It was programmed by Andy Guevara. Ms. Candyman is the sequel to 1983's Candy Man, which was released on tape. This is the description of the game from an advertisement: "Real arcade action with joysticks, 1 or 2 players and 3 levels of difficulty. More than 20 screens, each faster than the one before. Full screen display in exquisite detail. Ms. Candyman must pick up all of the lifesavers as quickly as possible while avoiding contact with the Ghosts & Goblins. During the first half of a screen the Ghosts or Goblins will try to catch you. During the 2nd half of a screen the Ghosts or Goblins will take up protective positions to keep you away from the life savers. Each contact costs Ms. Candyman one life and she will nose-dive head first off the bottom of the play field. A wrecker or ambulance will carry her off."

  • Candy Man is the prequel to Ms. Candyman by L&M Software. It was released on tape. It loads via the Astrovision release of Bally BASIC (usually called "AstroBASIC"). The game was written by Bill Loos and Greg Miller, who make up L&M Software. It's unclear to me how much of this game is written in BASIC, but by the speed of this game, my guess is that it relies heavily on machine language subroutines built into the Bally's 8K on-board system ROM. Andy didn't directly work on Candy Man, but the programmers of the game might have used his machine language routines in the game.

  • Ms. Candyman Ad - L&M Software's very rare cartridge release for the Astrocade. This game is one of those rare occasions where the rarity of the game does not speak about the quality of gameplay. A great game.
  • Ms. Candyman Review - Michael Prosise reviewed Ms. Candyman in his "The Game Player #13" column in the November 29, 1983 of the Arcadian newsletter.
  • Ms. Candyman Disassembly - This is a partially commented Z80 disassembly of Ms. Candyman. All of the games graphics were found and most of the code was disassembled, but not commented. Hopefully Andy can provide the printed source code listing so that this game can be completely commented.
  • Ms. Candyman High Score Club - Ms. Candyman was played for the Astrocade High Score Club in June 2017 for HSC02, Round 6: Ms. Candyman / The Mummy's Treasure.


  • Chicken! - The Bit Fiddlers, 1982. It's late... you've got to get your brood home in time to watch "Fowl Play." The only problem... there's six lanes of freeway between you and home. And every day it seems to get worse... CHICKEN! is a one or two player game of skill. It pits each player against six lanes of highway of ever increasing traffic density. The object, of course, is to get your chickens across the road.

  • Chicken source code - This is Richard Degler's disassembly of the Bit Fiddler's "Chicken (The Bit Fiddlers).bin." This game originally loaded via Bally BASIC, AstroBASIC or the "Machine Language Manager." This version of the binary will run as a cartridge.

Goldfish Demo

  • Goldfish Demo - Seven goldfish (actually they are neon tetras) swim around a fishtank, a clock runs, and a cat meows every minute.

  • Goldfish Source Code - In January 2008, Lance F. Squire converted the Goldfish Demo to run as a cartridge.

Standard Color Generator

  • Standard Color Generator - By Andy Guevara/The Bit Fiddlers. BASIC EXPRESS, THE 3, no. 2 (May/June 1981): 15-16. "Machine Language Manager" Manual (Page 7-4) This video test software generates 8 standard colors used in TV work. It is for use with the Bally Arcade/Astrocade and Bally BASIC or the Machine Language Manager. The "Standard Color Generator" program will display a series of color bars which can be used to set the colors on your TV set. The color bars are displayed from left to right in the following order: Black, White, Yellow, Green, Blue, Magenta, Red and Cyan. This video is broken into several part: Overview of Program, Program Loading and Running (Direct Capture), and Program Loading and Running (Video of TV). This program is useful to help adjust colors on a TV. It's also an excellent example of showing more than the usual two colors on the screen at once from BASIC.

The Bit Fiddler's Corner

  • Andy Guevara programmed the "Machine Language Manager" ("MLM") cartridge for the Astrocade as well as writing "The Bit Fiddler's Corner" tutorials to help support the program. The tutorials complement "MLM," but they also have a general focus, so this information can be used without reinterpretation by Bally Arcade/Astrocade assembly language programmers, or those wishing to learn about the machine.
  • The Bit Fiddler's Corner - Links to each article in the series as they appeared in the Arcadian.
  • The Bit Fiddler's Corner - These tutorials were converted to text by Adam Trionfo on January 13, 2002. This is the complete series in one Rich Text Format document.

Andy Guevara - Miscellaneous Links

  • Atari Archive - Kevin Bunch is "chronicling the early history of video games with mini-documentaries focused on a particular game or topic.
  • Z-80 SoftCard - Bit Fiddler's programs were created using this Z-80 card, or one similar to it, for the Apple II Plus.
  • "Astrocade Owners!" Advertisement - This half-page ad appeared in the January 1983 issue of Electronic Games. "Here's a list of professionals who support your computer with programs, hardware and information to help you enjoy your Astrocade to the maximum!" Each of the 17 companies listed in the ad has contact information, along with a brief summary of what they do. Running this ad was very expensive. Richard Houser, from Astrocade Sourcebook (one of the companies in the ad), has said that everyone in this ad grouped together funds to run it for several issues in Electronic Games magazine. When asked if the ad worked at all, Richard said that it did have noticeable results. A higher-quality version of the just the ad can be read here.

Next Episode's Coverage

Astrocast #16 was supposed to be the first of a sporadic multi-part series that covers some of the material in the "AstroBASIC" manual. That episode was bumped to make room for the interview with Andy Guevara. The "AstroBASIC" manual overview will be in Astrocast #17.

In episode #15 of the Bally Alley Astrocast, Adam conducts a user interview with David Kindred. David got his Astrocade console in 1981 when he was eleven years old. He learned to program in Bally BASIC, which caused a spark that eventually ignited into a flame that drove David to college where he studied computer science and information technology. He worked for 25 years as a computer programmer, beginning with Fortune 500 companies, before he moved into IT management, where he works to this day.

In this podcast, David explains how using the Bally/Astrocade helped to shape his early views on programming and how the system and its BASIC programming language allowed him to be precise in his thinking. Lastly, lets not forget the fun tale of the subtle drawing of a tree with toilet paper hanging from its limbs that he created with a friend using the Astrocade's built-in program, Scribbling. Why would he draw this small wonder of art? This humble drawing glorified the cute misconduct of two thirteen year old boys who had spent the previous evening TP-ing a neighbor's tree.

If you have ever wondered what it felt like to be the owner and user of a minority game system like the Astrocade, then David can help fill in some of the blanks that are so hard to come by when talking to people who grew up with the more mainstream game systems like the Atari 2600 or much more popular computers like the Apple II.

In episode 13 of the Bally Alley Astrocast, Adam and Chris review the Bally Arcade/Astrocade game "Cosmic Raiders," a horizontally scrolling shoot 'em up. "Cosmic Raiders" is a game released in 1983 on an 8K cartridge by Astrocade Inc. It is part of the Action/Skills Series and is part #2019. It was written by Bob Ogdon, Scot L. Norris, Julie Malan, and Lisa Natting.

"In deep space lies the alien sector Larkin. You are there on a mission to obtain energy sources that have been seized by the evil Larkins. Radar and a superior guidance system help you avoid attacking fighters and Kamikaze ships. The energy stars are near the Larkin command ship: you must retrieve them before you can leave the enemy sector."

Hamurabi Notes

  • King Hamurabi by Richard Houser - "King Hamurabi," a Bally BASIC game appeared in Arcadian 2, no. 4 (Feb. 25, 1980): 32-33 and on the tape "Best of Arcadian - 1980." In this video, Dominic and I play a few games to help listeners of the Astrocast to better conceptualize how the game is played.


  • Sorry, there is no feedback in this episode...

Dec 16, 2019

In episode 10 of the Bally Alley Astrocast, Adam and Chris++ review the modified version of the "AstroBASIC" game Gobblers. They also discuss just a few of the many updates to the website since March 2017. Finally, they talk about some of the recent occurrences in the Astrocade community. This is the first full-length episode in over 2 1/2 years; thanks to all those Astrocade fans who kept pestering Adam for another episode.

Some Astrocade News/Updates

  • Astrocade Video Art - BallyAlley's YouTube Playlist
  • Astrocade Video Art -
  • MOD 2 by Dan Sandin - "MOD 2," a Bally BASIC video art program, that appeared in an article called "Pix-Art" by Frank Dietrich and Zsuzsanna Molnar. This article, which appeared in "Computer Graphics and Art," 1980-1981 Yearbook 5, covers the Bally Arcade as a low-cost solution to create graphics using Bally BASIC and the ZGrass language. It specifically talks about several pieces of art that were written using the two languages. Some of the video art pictures are included in the article, as well as some source code for a few programs.

  • Astrocademo - By Genesis Project. Demo for the Bally Astrocade (1978). Code by Shadow. Music by MCH.

  • 2000-Baud "AstroBASIC" Tape I/O Support Missing - Summary of Missing Feature at MAME Testers
  • Bounty: $100 for Astrocade Tape Support- Thread at requesting tape support be added to MAME's Astrocade emulation.
  • Bally Arcade / Astrocade Real Hardware Timing Test - This video was created using real Bally Arcade/Astrocade hardware. Two programs are run that use clocks which can be used for timing real Bally Arcade hardware versus emulation. One program, Goldfish Demo, is written in machine language. The other program, Grandfather Clock, is written in BASIC. This video can be used to test how the emulation speed is for Astrocade emulation. Each program is run for three minutes.

  • Bally BASIC/AstroBASIC Differences - The "Bally/Astro Basic" section of the html version of the Astrocade FAQ.
  • Bally Alley Astrocade Discussion Group - There is an active Astrocade discussion group at that has its roots dating back to 2001 at Yahoo Groups. You can browse the over 16,000 messages that were moved from the original Yahoo groups to the site in the fall of 2019. In addition, the site is now the current place to talk about the Astrocade today.
  • Palo Alto Tiny BASIC, Version 3 - By Li-Chen Wang. This article is excerpted from PCC's Reference Book of Personal And Home Computing, Edited by Dwight McCabe. 1977. Pages 58-88. Bally BASIC (and "AstroBASIC") are a superset of the original Palo Alto Tiny BASIC. This version of Li-Chen Wang's Palo Alto Tiny BASIC will run on either the 8080 or Z-80, and only uses 2K of core memory. It contains a number of nice features including command abbreviations and error messages. At the end of the listing is a cross reference table for symbols used in the program and also the object code for the program. For further information on Tiny BASIC languages, see Dr. Dobb's Journal, Volume 1.
  • Gunfight: A Z80 Instruction by Instruction Breakdown- By Michael Matte - 198x. In the 1980s, Michael Matte, a passionate Astrocade user, used the Z80 source code listing for the 8K ROM, available in the "Nutting Manual," as a basis for his detailed breakdown of Gunfight. Michael created the breakdown "to provide beginner assembly or machine language programmers an inside look at the game Gunfight. The documentation will reveal how on-board subroutines in the System ROM can be used to execute particular tasks. The 'special routines' listing can be used as a reference source for programming demos or games." The archive includes Michael Matte's complete, 42-page breakdown of the Astrocade game Gunfight. This breakdown will be most useful if used with the source code for the Bally's 8K system ROM, which is available in the "Nutting Manual."
  • Astrocade High-Resolution Upgrade - By Michael Matte (Circa 1985/1986/2019) - These five in-depth "packages" (documents) were created by Michael C. Matte in 1986. These documents explain how to upgrade a Bally Arcade/Astrocade from the "Consumer Mode," which uses the low-resolution display (160x102 pixels), to "Commercial Mode," which uses the high-resolution mode (320x204 pixels) used in arcade games such as Gorf and Wizard of Wor. There are pictures of Michael's hi-res unit and screenshots here too.
  • Hi-Res Bally Arcade/Astrocade Correspondence and Hi-Res Project Updates - I have added correspondence from 1985 and 1986 between Michael Matte, Don Gladden (who edited volume 6 of the Arcadian) and Bob Fabris. Michael wrote the documentation on how to upgrade the Bally Arcade to hi-res mode. His letters primarily deal with this matter, but he also drops some wonderful tid-bits, such as that he made a BalCheck II for his hi-res unit. He also upgraded the Machine Language Manager cartridge so that it could take advantage of hi-res mode.
  • SetScreen 2: An Upgraded Bally Arcade/Astrocade Troubleshooting Utility- By MCM Design/Michael Matte. October 2017. Setscreen 2 is a visual troubleshooting tool that can be used to help diagnose a failed Astrocade motherboard producing a blank TV screen at power-up.
  • GitHub Astrocade Code Repository - Rachel Weil's (aka "hxlnt") GitHub annotated Z80 assembly source code, binaries, and dev tools for the Bally Astrocade.
  • A Power Transformer Substitution for the Bally/Astrocade Computer System- By Michael Matte (MCM Design). April 2018. If your original Bally power supply fails, and you have experience in electronics, then these instructions explain how to build a substitute power transformer.
  • "Treasures of Cathy" - By John Collins. 1982.This adventure-style game has 49 locations with 18 treasures. You can only carry six treasures/items at a time. Each treasure gives additional points. Each move subtracts one point. Try for a score greater than 1,000 points. There are four keywords: IN, UP, DROP and GET. On September 7, 2018, this game was played by Chris++ and Adam Trionfo. A rough, incomplete map of the game was created to help figure-out the game's layout. To answer Paul's 10-year-old question: to enter the house, climb one of the trees in the game (type UP), and then GET the key from the bird's nest. With the key, the player can enter the house by typing IN.


  • The Astrocade Turns 40! - AtariAge Thread. - The first Bally Home Library Computer Arcade finally shipped and arrived in people's hands in late January 1978. Many of these people who got their units had ordered their system from a three-page JS&A ad that appeared in the September 1977 issue of Scientific American. Happy birthday, Astrocade! The Bally is now 40 years old and we're still fiddling around with it. Good for us! If anyone has any stories to tell about the Astrocade (especially if you got your system in 1978 or for your birthday!), then I'd love to hear your tales!
  • Private Screenings: The GAMES Guide To Home Video Games- By Phil Wiswell - From December 1982 GAMES magazine - "Mezmaron" mentions this article in his feeback to the show. Page 38 of the magazine (page two of the article) has the Astrocade system on it.
  • History Panel: "The Arcadians: Exploring the history of homebrew for the Bally Astrocade"- For any enthusiasts who are going to Magfest or live on the east coast, Rachel Simone Weil and [Kevin Bunch] will be running a history panel all about the independent developer/enthusiast scene that cropped around the Astrocade! There is also an AtariAge forum thread on this topic.

Gobblers (Mod) by Bob Wiseman and Klaus Doerge

The original version of Gobblers is from Arcadian 3, no. 12 (Oct. 05, 1981): 125. The modified version, with updates by Klaus Doerge, is from Arcadian 5, no. 4 (Feb. 18, 1983): 56, 70. "This is a two-player game played on a 10x5 field. The object of the game is to have your Gobbler gobble-up more squares than you opponent. When play begins, use the JX and JY to direct your Gobbler around the screen. Each printed square is worth 1, 2, 3, or 4 points, depending upon how many dots are there. The game ends when the last square is eaten."

In episode 9 of the Bally Alley Astrocast, which is only about three minutes long, Adam very briefly discusses that the next podcast episode will focus on the Bally Arcade/Astrocade community of the past and present. He asks for the Astrocade community to send feedback to be included in the next podcast.

In episode 8 of the Bally Alley Astrocast, Paul, Michael and I review the 4K Blast Droids cartridge that Esoterica released in 1983. This game was written by Dan Drescher, and J.P. Curran. We also review the BASIC game Haunted House released by New Image in 1981. Paul and I discuss the contents and programs included in the August and September 1979 issues of the Arcadian newsletter. We also read feedback from Arcadian readers that sent letters and postcards to Bob Fabris concerning the July 1979 survey question that asked if users would purchase a third-party keyboard and RAM upgrade. Lastly, we cover about ten letters that cover general topics that were sent to the Arcadian from late July to September 1979.

Haunted House (Tape)

  • Haunted House - "AstroBASIC" 2000-Baud version.
  • Haunted House Bally BASIC Instructions - These are the program instructions and BASIC listings for New Image's Haunted House. This game is very unusual because it is made up of nine different loads, each of which is a separate BASIC program.
  • Haunted House "AstroBASIC" Instructions
  • Treasures of Cathy ("AstroBASIC" Program) - This programs, by John Collins, seems like a fairly complex dungeon-crawler type game.
  • The Crown of Zeus by Todd Johnson - This game is probably the most RPG-like game on the Astrocade. It is for AstroBASIC only. It takes you to a dark decaying castle in the evil land of Sorom. You've been asked, as the best warrior in the land of Beekum, to retrieve the Crown of Zeus which the Scromites have stolen. The crown, when worn, gives the wearer the awesome ability to cause anything he or she wishes to vanish. Apparently the Scromites have not yet discovered the crown's powers. But as you hid in the forest outside the castle, you saw a troop of orcs from the warring land of Machor slip in through the front gate. They surely know the power of the crown and will have to be dealt with...

Arcadian Newsletter

  • Arcadian 1, no. 9 (Aug. 18, 1979): 69-76. - The ninth issue of the Arcadian newsletter.
  • Arcadian 1, no. 10 (Sep. 31, 1979): 77-84. - The tenth issue of the Arcadian newsletter.
  • Arcadian 1, no. 10a (Sep. 31, 1979): 80a. - A supplemental page to the tenth issue of the Arcadian newsletter.
  • TV Output Notes by Marc Calson (possibly a misspelling of Mark Carlson). - The four pages of this document were created using the output of a short 10-line, BASIC program. Whoever sent this document to Bob methodically noted down four sets of numbers for each ASCII character. I can't say that I understand the listed decimal number information, but it seems to nicely supplement the August 1979 issue of the Arcadian's music coverage from Robert Hood (American Concert Frequencies) and the second part of Chuck Thomka's music tutorial, The Music Synthesizer.
  • Hit the Pedestrian by Sebree's Computing (Timothy Hays) - This is a hand-written type-in program listing for Bally BASIC. Typed instructions are included. This program has not be digitally archived.
  • Pictures of the Viper RAM Expansion - This hardware was released by Alternative Engineering.
  • Pictures of the Keyboard for the Viper RAM Expansion Unit
  • Aldo Trilogy by Dave and Benjamin Ibach - Three PC shareware titles for DOS released 1987-1991. These games do not run on the Astrocade. These games will run well under Windows when using a program called DOSBox (an emulator, of sorts). The games included are: Aldo's Adventure, Aldo Again, and Aldo's Assault. While these games won't run on the Astrocade, they do give a continued history of what Dave Ibach did (with his son) after he moved on from the Astrocade. The main character in this series of one-screen platform games looks suspiciously like someone named...Mario. Give these games a try-- you'll like 'em.
  • The Bit Fidder's Corner by Andy Guevara - The Bit Fiddler's Corner is an Astrocade machine language programming tutorial that ran as a series of serialized articles in the Arcadian newsletter in 1983 and 1984. The author, Andy Guevara, programmed the Machine Language Manager cartridge for the Bally Arcade/Astrocade. This tutorial complements that cartridge, but has a general focus so this information can be used without reinterpretation by Astrocade assembly programmers, or those wishing to learn about the machine.
  • The Music Synthesizer by Chuck Thomka - A tutorial on creating sound effects for the Astrocade.
  • Black Box by B. Reany. - This Bally BASIC (300-baud) program was printed on page 74 of the August 1979 issue of the Arcadian. Black Box is a sort of Battleship game where the computer hides some "atoms" in a grid and you have to locate them. Use the diagram for clues.
  • Space War by Dave Ibach - A 300-baud, Bally BASIC game that was printed in the September 1979 issue of the Arcadian. It's a neat idea for a two player game. Each player has a ship on one side of the screen, and can move up and down and fire at any angle. However, the ships are invisible, so you can only figure out where your opponent is when they fire a shot.
  • XY Tutorial by Timothy Hays - A 12-page tutorial on the Bally BASIC XY command for exceptionally well controlled graphics.
  • XY Tutorial Programs by Timothy Hays - This archive includes the Bally BASIC programs included with the XY Tutorial document. The six programs included are: 3-D Forward Simulation Above A Flat Plane, Cartesian Coordinates To XY Values Routine, Demonstration Program #2, Demonstration Program #2 (with Additions), Demonstration Program #4, and RND XY Value To Perspective Point.

Responses to the Arcadian July 1979 Survey

These letters relate to the programming keyboard survey on page 55 of the July 1979 issue of Arcadian. As a reminder, the survey questions were:

  1. "Assume that the Bally keyboard is available with full capacity (reference page 21). Are you ready to pay $650 for it?
  2. "Assume that the Bally keyboard is available with partial capacity (reference page 54). Are you ready to pay $350 for it?
  3. "Assume that we develop a keyboard that would have 16K RAM with upgrading capability of 24-plus K RAM, and some form of resident BASIC in 16K ROM, along with some features such as cassette motor control, word processing capability, etc. Are you ready to pay $350 for it? (Assuming that Bally does not produce in the same timeframe.)

"A postal card with numbers down the side and yes/no opposite each is all that is necessary, but suggestions are certainly welcome. Also, tell me the model number and serial number of your machine if you haven't done so yet."

Letters to the Arcadian

  • Letter from Chuck Thomka to Bob Fabris. (1979, probably late January). - Chuck sent two programs with this letter: Modified Player Piano for Learning Aid on the &16 - &23 Commands and Leaning Aid for "&" Command. It seems that these two programs helped Chuck figure-out the sound capability of the Bally Arcade. He went on to use this information to write the Music Synthesizer tutorials in the July and August 1979 issues of the Arcadian. Chuck describes the printer that he uses to create the BASIC listing forms, "It actually doesn't take too long to create a form on what I use, which is a cross between a computer and a very high-speed line printer. It puts images on paper with laser optics utilizes Xerox xerographics. It's really quite an impressive machine. As an example of what can be done with it, well, if you can envision an 8 1/2" x 11" blank piece of paper and another 8 1/2" x 11" completely black piece of paper, this represents the extremes of the machine. Everything in-between (just about) can be done by this machine. That includes all different font sizes and styles, logos, lines and even signatures! All this with about the resolution of 300 dots to the inch. The speed of this machine is two full pages a second. If you wanted to print with a reduced print style and also have put two sides of data on the same side of the paper, this machine would print at equivalent speed of 36,000 lines per minute! Like I said, a very high-speed line printer!"

    • Leaning Aid for '&' Command by Chuck Thomka. - A five-page program that is purely Chuck's own concoction. This program uses all but about 150 bytes of memory and is somewhat involved, but is informative as to the workings of all the possible '&' commands.

    • Modified Player Piano for Learning Aid on the &16 - &23 Commands by Chuck Thomka - Submitted to Arcadian on January 5, 1979, but previously unpublished. A single-page modification to an existing Bally program which allows easy and quick changes to '&16' through '&23 commands [the sound ports].

    • Dealers of Lightning: Xerox PARC and the Dawn of the Computer Age by Michael A. Hiltzik - Chuck Thomka works worked a Xerox, and he mentioned what sounds like a laser printer in his letter. This is an link to Dealers of Lightning, a book published in 2000. The creation of the laser printer is discussed in some detail here. It "is a fascinating journey of intellectual creation. In the 1970s and '80s, Xerox Corporation brought together a brain-trust of engineering geniuses, a group of computer eccentrics dubbed PARC. This brilliant group created several monumental innovations that triggered a technological revolution, including the first personal computer, the laser printer, and the graphical interface (one of the main precursors of the Internet), only to see these breakthroughs rejected by the corporation. Yet, instead of giving up, these determined inventors turned their ideas into empires that radically altered contemporary life and changed the world."

  • Letter from Tracy Crook to Bob Fabris. (About 1979). - "I wanted to let you know where I am on the Bally expansion. So far, I've added 16K RAM, one serial port, two parallel ports and an ASCII keyboard. These all work very well. What has not worked so well, is some special logic used with the non-mask will direct. With this, I had hoped to use the Bally BASIC unmodified with the keyboard I added. As it is, I can input data from the keyboard under basic control (or machine language), but program entry and editing must still be done through the keypad. I can't get this to work, I guess Bally BASIC (or some other language) could be placed in RAM. A commented listing of Bally BASIC would be invaluable at this point. [...] With that info, we could tailor it a bit and put it in RAM.

    "At this point, I see the remainder of the expansion to be mainly a software effort, which is where I could use some help. The most important changes, I think, would be to get BASIC program storage out of internal (graphics) memory. This would greatly increase the color capabilities when using BASIC." [Note: Blue Ram BASIC does this, which is why more colors are available to this expanded BASIC.]

    "Another interesting possibility open by having RAM memory available is the ability to load it with data from any of the game cartridges (which were previously dumped onto a cassette tape) and then switch this memory into the bank normally signed the plug-in cartridge. This is quite easy to do. At this point the Bally would perform exactly as if you had plugged in the game cartridge that the data came from." [The Blue Ram, Viper and Lil' White RAM expansion units all allow for this.] "The end result would be that you could have the entire library of Bally games in a couple of cassette tapes. Bally might not be too wild about this idea, I assure you it would work."

    "In the meantime, in order to ease programming the Bally, I use another one of the microcomputers I own, which has an ASCII keyboard, to write Bally BASIC programs on and then dump them on tape in a format compatible with the Bally. Doing it off like this has some disadvantages, but it sure beats that key pad."

    "Haven't done much on it lately, as my Bally was struck by lightning about five weeks ago, and it still not back from the factory."

  • Letter from Ed Mulholland to Bob Fabris. (July 1, 1979 / July 23, 1979). - In the July 1'st letter, Ed says, "The schematics to our Ballys show a 10-pin and a 26-pin port in addition to the IEEE-488 port. My machine did not have 26-pin port as shown in the photo on page 14 of the [Bally PA-1] service. This would still be only a small inconvenience because the pin numbers and functions as shown on the schematic."

    The second part of the letter (dated July 23) shows how the 10-wire 24-key keypad is arranged. I think that this information is meant to help explain how to wire a 63-key "full size" ASCII keyboard in parallel with the 24-key keypad.

  • Letter from Robert Dahl to Bob Fabris. (July 29, 1979). - Mr. Dahl suggests that future issues the Arcadian leave room so that a hole punch can be used so that the issues can be stored in a binder. He says, "They are well worth saving." I agree!

    On July 27, Mr. Dahl received a mimeographed copy of the Hacker's Manual from Bally. He notes that they included a letter that says they do not expect the keyboard expansion to be released this year

    Robert Dahl notes that he was able to order the Amazing Maze/Tic-Tac-Toe cartridge from Montgomery Ward's catalog. He got the cartridge in just three days. He adds that a fellow, who sells the Arcade and its accessories, tells him that he has a standing order for all arcade items, but gets more promises than anything else from a wholesale distributor in Milwaukee. This man had been trying to get the Amazing Maze cartridge ever since he first heard about it and he had yet to get it. Mr. Dahl figures that Bally's distribution must be out of whack.

    Mr. Dahl has typed in various versions of Slot Machine. He talks about three that he has used comparing and contrasting differences between them.

    Mr. Dahl makes a comment that the Checkers game number six had him puzzled. He was expecting a regular checkerboard on the TV screen. He says that, "Right now, it's beginning to soak-in that I should take a checkerboard and number the squares and move the pieces around as the numbers on the screen direct?" [Is this accurate?!?]

  • Letter from Andy Guevara to Bob Fabris. (July 30, 1979). - Andy Guevara wrote several programs that were published in the Arcadian and Cursor/BASIC Express newsletters. Andy programmed the Machine Language Manager, a 2K cartridge that was released in 1982 by The Bit Fiddlers. He released a few tapes, including Candy Man and Chicken, two games released on tape that were written in mostly machine language. He wrote Ms. Candyman and Sea Devil, both of which are 4K cartridges that were released 1983 by L&M Software. Mr. Guevara also wrote The Bit Fiddler's Corner, an Astrocade machine language programming tutorial that ran as a series of serialized articles in the Arcadian newsletter in 1983 and 1984.

    Andy just received his first stack of Arcadian newsletters. He has had his Bally arcade for five months and never dreamed that so much information could be further developed. He has dumped the Baseball cartridge, and is pleased to see that other people have made ROM dumps too.

    Mr. Guevera is looking into expanding his internal memory from 4K to 12K of RAM with a single IC designed by Harris Semiconductor. He goes into detail about how this might work.

    Andy has come up with a solution for Bob to be able to print programs. He provides details and a schematic on a device that can be used that will use a UART to allow the Bally to print.

    Although Andy has only had his Bally Professional Arcade model BPA-1100 for five months, the innards have already had to be changed twice.

  • Letter from Richard Dermody to Bob Fabris. (July 31, 1979).- Richard's interest has been piqued by the announcement of the keyboard project. So much so, that he has already gone out and bought a keyboard for the project. He says, the "glimmer of a future for the Arcade as a computer [...] has prompted [him] to retain his [Arcade] with hopes for the future."

    Richard notes that while he understands the difficulties that Bally may be having with the FCC, he has noticed that other companies, such as Apple, have made significant progress in the same time period since the Arcade was first announced.

    Richard is on his second Bally arcade. He had to return his first one to Montgomery Ward as "it tended to self-destruct after being in operation for a while."

    Mr. Dermody hopes that reviews of the Bally cartridges will be in future issues. There is no local retailer for these items where he lives so his only resort is mail-order. He would like to have some idea of what he is ordering before he places an order.

  • Letter from Guy McLimore to Bob Fabris. (July 31, 1979).- Guy gives an unqualified "yes" to all the survey questions that Bob asked the previous issue of the Arcadian. Guy says that he wants and needs a keyboard badly.

    An interesting bit here is that Ken Ballard, the owner of ABC Hobbycraft, has commissioned a professional hardware/software man to develop a 64K keyboard memory expansion to be sold commercially. The unit is still in the planning stages, but [they] hope that it will be ready by December." This seems overly optimistic, since it is nearly August already. I don't recall ever hearing about this from any other source. It is interesting that so many people wanted to build, create or purchase a memory expansion/keyboard for their Bally unit.

    Guy really enjoyed Chuck Thomka's synthesizer tutorial. He found the two accompanying programs very useful. He does wonder how Bell Telephone feels about the programs, however. He notes that if you add the buttons A-D to the Touch-Tone dialer program (Touch Tone Simulate), then you have a semi-efficient Black Box for receiving free telephone calls. The Touch-Tone dialer doesn't work in Guy's local area. He thinks that Indiana Bell has an acoustical filter that prevents Touch-Tone signals from being input to the microphone from the handset.

    By popular demand, ABC hobby craft is now accepting mail orders for Bally hardware, W&W software, Stocker Software, and Skyrocket Software (Guy's company).

    Guys makes an observation about the tape quality for software that is being sold through the Arcadian classified ads. It seems that the people distributing their software on tape are using cheap tapes brands which makes loading the tapes difficult. He notes that the Dave Stocker software is also available on micro cassettes. I don't know of any other Bally software that was distributed on these tiny tapes.

    Guy has been pleasantly surprised by the amount of response he received to the listing of his Fantasy Games #1 package in the Arcadian. Despite the fact that it is a limited program designed only for those persons familiar with fantasy role-playing games, such as Dungeons & Dragons, the program sold remarkably well! Phenomenally well, in fact, given an audience of relatively few people.

    Guy will be creating programs under the name Skyrocket Software with his partner Greg Poehlein. They intend to sell software for the Bally, TRS-80 and eventually other systems. He says they won't be turning it out fast, but they will be turning it out good, paralleling Bally's own stated policy of producing fewer top quality cartridges as opposed to Atari's more is better philosophy

  • Letter from Jeff Frederiksen to Bob Fabris. (August, 20 1979).- This letter is from Jeff Frederiksen, the chief engineer behind designing the Bally Professional Arcade hardware. It seems that this letter was accompanied by some hardware. The letter simply states: "The enclosed assemblies replace the 75361 clock driver, located in the oscillator shield. The failure of the 75361 is that the 6V high time after warm-up drops below 55ns causing the data chip to appear defective. If you do not have this sinking clock syndrome, replacement is not necessary. I hope you find the enclosed hardware description useful."

  • Letter from Jeff Grothaus to Bob Fabris. (August 31, 1979). - Jeff is building his own cassette tape interface from the schematics on page 20 of the Arcadian and page 4 of the Bally Hacker's Manual. He has run into a few difficulties and is hoping to get some help. He also wonders if Bob knows if anyone else has created a working interface from the schematics. There's a handwritten note from Bob where he simply writes, "No."

    I find it interesting that Jeff is actually building his own tape interface. This interface would be of no use without the basic cartridge. At the time, I think, the tape interface was easy enough to get for $50. I wonder if Jeff was trying to save money, or if he was having difficulty finding the necessary hardware to use with Bally BASIC and a tape recorder.

  • Letter from Karen Nelson to Bob Fabris. (September 10, 1979). - Karen is a programmer who got interested in the Bally when JS&A advertised it in Scientific American in 1977. She was told that she was one of the first people to get her hands on one. She was very excited about machines potential, but was disillusioned by the heat problems which were inherent in the first machines. She "burned out" two of the units. Just after she returned the second unit, she discovered that her programming instructor was doing the graphics for the Bally. She says, "Yes, folks, it was the infamous Tom DeFanti and his magic Z-GRASS." She knows Tom well enough to drop into his "Graphics Habitat" at the University of Chicago to talk intelligently about some of his projects. She also knows Nola Donato and a few other of Tom students who are working on projects for Bally. Tom has had the University of Chicago purchase eight Bally's and eight Sony TVs to teach students the basics of computers and programming.

    In August 1979, Tom was the chairman of a traffic seminar held jointly by IEEE and ACM/SIGGRAPH. For three nights, Tom and his crew presented new and interesting works in various areas of computer graphics (including a few by people using Bally Arcades). In addition to the seminar, a graphics experiment Expo was held and it was there that Karen met some of the guys from Dave Nutting, in particular Ricky Spiece (who developed the Football cartridge). Ricky was helpful and showed Karen some tricks (like the ports in BASIC), and he also demonstrated the graphics capabilities by loading a picture from a disk to a color monitor. In addition, his Bally was connected to a B&W monitor and a keyboard. His commands appeared on the black-and-white monitor, and the graphics were displayed on the color monitor. However, the whole setup was attached with the Bally board mounted in a frame, not in the case, which leads Karen to believe that some special wiring is needed.

    Karen describes her experimentation with the different ports available in BASIC.

    Karen has recently seen the pinball cartridge demoed at the graphic seminar. She says that it looks pretty good. She heard one of the Dave Nutting guys say that he had just sent the thing off to Bally and that it should be out on the market pretty soon. Karen says that there was a demo of Z-GRASS, but that she didn't get to see it. She does note that as a student of De Fanti, she learned how to program in GRASS-- Z-GRASS's daddy-- using a PDP-11/45.

    Karen is glad to find out that there are other people like her who think that the Bally Arcade/computer has a lot more potential than most people give it credit for. She hopes that Bob Fabris might be able to pass on some information to whoever the marketing manager at Bally is. She would like to see the Bally advertisement computer magazines such as BYTE and Personal Computing. She would like to see Bally stress that most people buy home computers for games and that Bally has terrific controls, and that by the time people become interested in programming, Bally will have add-on module available. She also says that the graphics capabilities of the Bally have no competition; they are the best, and the Arcade is dirt cheap when compared to other systems.

  • Chopsticks WAV File - The song Chopsticks is taken from WaveMakers' Music Keyboard, a BASIC program that allows the user to create 2-voice music using an on-screen piano keyboard. The music could then be exported to tape and then used in your own program. Music Keyboard was released on in December 1982 on Tape 17. It was also released on WaveMakers' tape 19 and Astro-Bugs Club Tape #1 (without the chopsticks music that is played on the title screen). It was later reprinted in the Arcadian.

  • Three Voice Music Program - This "AstroBASIC" program, by Brett Bilbrey and George Moses, allows the user to create three voice music on the Bally Arcade/Astrocade. This program was printed in the "AstroBASIC" manual on page 70. This program can be used on real Astrocade hardware to create new music. I encourage people to make music on the Astrocade using this software and then to send it in for inclusion on the Astrocast. I'd love to see music submissions start to pour into the show!

Michael's History with the Astrocade

  • Astrocade Kiosk - This was the dealer's display cabinet, intended for small shops and large department stores. Made by the Santa Cruz Wire and Mfg. Co., this kiosk stood over five feet tall and resembled a coin-op cabinet. It came wired for 110 volts for use with the Astrocade and a TV (not included with the unit). There was a cartridge selector inside for up to ten game cartridges to be demonstrated (with a time limit); a "10 key" switch selected which cartridge was played.

It lists "the professionals who support your computer with programs, hardware and information to help you enjoy your Astrocade to the maximum! Contact any of them for details." Each of the companies listed has contact information, along with a brief summary of what they do. Running this ad was very expensive. Richard Houser, from Astrocade Sourcebook (one of the companies in the ad), has said that everyone in this ad grouped together funds to run it for several issues in Electronic Games magazine. When asked if the ad worked at all, Richard said that it did have noticeable results.

  • Swap 'N Shop Text Channel - Michael used the Cablevision Swap 'N Shop channel from his cable provider to sell his Atari 2600 in the early 1980s so that he could buy a Colecovison. This is an example of that channel for those (like me) who have never heard of this before. This is a five minute segment of a community access channel called 'Swap 'N Shop' from back in 1984. It is provided by Cablevision TV service in Downers Grove, IL.

  • Jameco JE 610 ASCII Keyboard Datasheet - These keyboards, from 1979, were often hacked with the 300-BAUD interface to create a keyboard that could be used with Bally BASIC. From the datasheet: "The JE610 ASCII Encoded keyboard kit can be interfaced into most any computer system. The keyboard assembly requires 5V @150mA and -12V @ 10mA for operation. Interface wiring can be made with either a 16-pin DIP jumper plug or an 18-pin (.156 spacing) edge connector."
  • Bangman (AstroBASIC) - This is the "AstroBASIC" (2000-baud) version of Bangman by Ernie Sams that appeared in Arcadian 1, no. 7 (Jun 15, 1979): 47-49. Bangman is a take-off on the classic Hangman word spelling game. It has two novel features - letters being entered are hidden from view of the opposing player - and the penalty for losing is not a hanging... One person keys in a word to ten letters; another tries to guess it with no more than nine wrong guesses using the knob and trigger.

  • The Music Synthesizer (Article, Text Format) - The Music Synthesizer by Chuck Thomka. "The synthesizer circuit, which is contained wholly within the 40 pin custom I/O chip, is a very versatile circuit which contains counters and amplifiers to give the programmer tremendous control of the three voice output along with a tremolo, vibrato, and even a noise generator. The output frequency range is very accurately adjustable from less than 14 hertz to ultrasonic frequencies. The upper limit may be set by the capacity of your TV sound system." This tutorial original was made up of two parts: The Music Synthesizer [Part 1], Arcadian, 1, no. 8 (July 1979): 62-66. and The Music Synthesizer, Part 2, Arcadian, 1, no. 9 (August 1979): 71-73. This text version of the tutorial is missing four parts as they appeared in the Arcadian newsletter. The missing parts are: 1) Sound Graph - A Bally BASIC program that allows access to the sound ports and makes a simple graph of the results. Arcadian, 1, no. 8 (July 1979): 65. 2) Touch Tone Simulate - A Bally BASIC program that can be used to dial phone numbers. Arcadian, 1, no. 8 (July 1979): 65. 3) The Sound Synthesizer as Perceived by Chuck Thomka - A visual overview of the sound ports. Brett Bilbrey has said that this has some errors, but he can't remember what they are. ARCADIAN, 1, no. 8 (July 1979): 66. and 4) Frequency Table - A table of all the sound generating keys, their &(17) values, the resultant frequencies, and any special notes about them. ARCADIAN, 1, no. 9 (August 1979): 73. The two tutorials have been extracted from the two different issues of the Arcadian newsletter and combined into one text document.
  • Sound Graph ("AstroBASIC," 2000-baud) - Sound Graph b Chuck Thomka from Arcadian, 1, no. 8 (July 1979): 65. This utility is part of the "The Music Synthesizer" tutorial by Chuck Thomka. In order to understand what "Sound Graph" is doing, the user must read the tutorial or at least have previous knowledge of the sound ports. With this knowledge, then you may be able to make some noises, but you won't be able to understand why they work or really what is happening. "Sound Graph" is an early BASIC program that allows direct access to the sound ports. The user can try making different sounds by changing the ports with an interface that uses hand controller #1..
  • Touch Tone Simulate - Touch Tone Simulate by Chuck Thomka from Arcadian, 1, no. 8 (July 1979): 65. and modification from Arcadian, 2, no. 10 (Sept 1980): 90. This utility allows the user to type in a phone number, and then dial it by placing a phone near the TV speaker and then pressing PRINT. The Bally Arcade will automatically dial the phone number. Make sure that when you use the program that your TV's volume is set to a high enough level so that your telephone can "hear" the TV.
  • Fabris/Thomka (Phone Conversation) - A very technical phone discussion between Bob Fabris and Chuck Thomka about circuit frequencies. This was probably recorded on January 2, 1982. This recording (in FLAC format) is 15:29 long.
  • Memory Display (Bally BASIC, 300-baud) - Memory Display by Chuck Thomka from Arcadian, 1, no. 8 (July 1979): 67. This is a machine language utility for BASIC. This program displays input memory locations in both Hexadecimal format (with hex pairs in reverse order) and Bally BASIC decimal format. This is a nice memory dump program that displays the decimal and hexadecimal location numbers (address) and data. It will do whole blocks of dumps by giving a starting and ending address. It will increment the address by the entered amount if you only want to check every 1000'th location, for example. Use negative numbers to check the upper memory: -32767D = $8001 to -1D = $FFFF.
  • Square Root (Bally BASIC, 300-Baud) - Square Root by David Stocker from Arcadian 1, no. 8 (Jul. 20, 1979): 67. The Arcadian does not have any comments or instructions for this program. Although the name implies that the program calculates a square root in BASIC, it would be impossible to know that while running the program as it gives no indication of what the program is asking for at the INPUT prompt. Only a look through the code would give a hint of that information.
  • Distance Between Two Points (Bally BASIC, 300-Baud) - Distance Between Two Points by David Stocker from Arcadian 1, no. 8 (Jul. 20, 1979): 67. The Arcadian has no comments about this program, though from the title it can be surmised that this eighteen-line calculates the distance between two points.
  • Bally Chess Board (Bally BASIC, 300-Baud) - Bally Chess Board by John Collins was originally offered for sale for $6.00 in 1979 (as Chess), then later printed in the Arcadian newsletter in the October 1984 issue on page 120.

Classic Letters

  • Ron Schwenk Letter to Bob Fabris (February 2, 1979)

    Ron gives early comments on a few cartridges: "Football is very good. They even have music with Vibrato! It sure sounds good. I quickly ran out of them, but should have more in a week. Maze/Tic-Tac-Toe is ok, but mainly for kids. I think that Star Battle is their poorest videocade and don't care for it at all."

    The add-under never made it out the door. It had issues from the start. Ron already has a criticism, "In the expansion unit it looks like they are increasing the amount of ROM but decreasing the RAM. And increasing the price!" Not only does the increase cost of the unit upset Ron, but he is confused by what's on offer. He hopes that Bob can clarify the statement, "To get 80 characters per line, does 'optional TV printer' mean a video monitor?"

    Ron has written a Mastermind game. This is mentioned in passing by Bob in the March 1979 Arcadian on page 31. There is an ad for Ron's Mastermind in the July 1979 Arcadian on page 68. The program was never printed in the Arcadian, but there is printed BASIC listing of the program available in the Bob Fabris Collection. Copies of two other games are also available: BatNum and One Check.

    Ron includes a one-page listing of the Bally items that he carries through his company Schwenk Enterprises. Among these items are the Bally Arcade systems. At the time the list price was $329.95 for a system with four controllers. Ron sells them for a cash price of $289.53 (or 296.95 for credit card purchasers). After looking over Ron's 11-cartridge listing, I noticed that the list price for 2K cartridges is $19.95 and the 4K cartridges sell for $24.95. Ron sells the carts for slightly cheaper than retail: his cash price is about $18 for 2K carts and $23 for 4K cartridges.
  • RM Martin Letter to Bob Fabris (May 28, 1979)

    Mr. Martin has some programming questions for Bob Fabris. Along with this letter, I found handwritten notes that Mr. Fabris prepared to answer the questions that he was asked.

    Mr. Martin says that his Checkers game, by John Collins, cheats. This game was printed in the May 1979 issue of Arcadian. As usually occurred, there were errors in the original listing. The June 1979 issue of Arcadian printed some corrections. Hopefully these got Mr. Martin fixed-up. Over the years, John Collins revisited his Checkers program, eventually making two major updates to it (calling them, quite originally, Checkers II and Checkers III).

    Mr. Martin asks how he can convert Star Trek and Wumpus written for other computers that have READ and DATA statements. The Bally doesn't support these commands, and he wonders how he can work around this limitation of Bally BASIC.

    All of the information in this letter is pretty typical for much of the correspondence that is written to the Arcadian. It's this letter's last paragraph that made me choose to include it in this podcast. Mr. Martin says, "You are doing one hellofa job. I have learned more about computers than I thought I ever would. Thanks." I'm not sure if this is an accurate summary of Mr. Martin, but I picture him as somebody who purchased his Bally Arcade to play games in much the same way that someone may have bought an Atari VCS in 1979. Then he stumbled into the Arcadian newsletter, bought Bally BASIC and was delving into his game system after realizing it could do much more than he originally thought possible.
  • Guy McLimore Letter to Bob Fabris (May 29, 1979)

    Guy recently received Scott Waldinger's version of the Star Trek program that he ordered. Scott must have ordered this from the classified ad in the May 1979 Arcadian on page 46. The instructions and the BASIC listing are available here:

    1. Star Trek by Scott Waldinger (Bally BASIC Listing)

    Guy hasn't had time to type in the listing yet, but it looked to him like Scott Waldinger found a unique way around the Bally's lack of substantial memory and multi-dimensional arrays. That's one of the neat details about the Bally system. People who owned it had to find interesting, and perhaps unique, methods to work around the system's minuscule 1.8K or RAM and limitations imposed by the Bally BASIC cartridge.

    It seems that Bob must have given Guy the corrections for Checkers, for its now working for him. He's glad there is a BASIC version of this program, "Bally has held up the videocade version." Actually, this cartridge never did ship, although a usable 2K prototype does exist-- though I've not played it. Guy says that the "the programmer [of Checkers] deserves applause for his work, as I would have bet it couldn't be done in 1800 characters."

    Guy is working on a light pen. The work is currently stalled, but if he gets it working, then he plans to sell it through the Arcadian. However, I don't think that this ever occurred. Some people in the Bally community did end up creating their own light pens, among them are Craig Anderson and Leroy Flamm. The Light Pen was supposed to be used with the Creative Crayon cartridge, but that cartridge never shipped and I don't think a prototype has ever surfaced.

    Bally's National Service manager told Guy that they planned to revise the Hacker's Manual and make it into an advanced operations manual. This never occurred. It seems that Guy already had doubts about it being released, for he mentions to Bob that if Bally falls through with this project then he thinks that someone, maybe even himself, should make such a manual for the Bally Arcade.
  • Laurence Leske Letter to Bob Fabris (June 6, 1979)

    This is a letter that Bob Fabris wrote to Larry Leske, an employee at Bally. Bob is hoping to get some more information on the internal workings of the Bally system. Bob says:

    "I publish a newsletter for owners of the ARCADE, and provide them with material which enables them to better understand the machine, and which informs them of operations that are possible. The inputs for my paper come primarily from the more technically oriented subscribers. I now have over 600 persons subscribing from across the country and Canada, plus a handful foreign, and we are all concerned about the status of the Add-On, or Programmable Keyboard. We have the Bally story of 'waiting for the FCC to act on the TI proposal', but we have also been waiting since last year when the Add-On was originally expected. Many of the subscribers responded to the JS&A advertising of Oct/77, and are quite frustrated with the situation.

    "We would be greatly interested in a surrogate keyboard, with additional memory capacity and capabilities approaching those which were advertised in the literature - a more powerful BASIC and a full-size ASCII keyboard, at least. In addition the units should have some equivalent to GRAFIX, ZGRASS, TERSE, etc., languages if at all possible."

    Before I continue with Bob's letter, I want to say how fascinating I find Bob's statements. He's basically writing a letter to Bally saying, "Hey buddy, we can't wait anymore for your delayed keyboard add-on, so we're gonna make our own." Imagine this happening today. You'd probably get a cease-and-desist letter from the manufacturer. Times surely have changed!

    Bob continues:

    "I am writing this letter on Jay Hess' recommendation to let you know that we as a group exist, and are interested in upgrading the system to higher capabilities. Of my group, I would suspect 70% to 80% would be in a position to purchase a unit in the $400-600 range.

    "I would be pleased to receive your comments and thoughts about our 'problem', and to answer any questions you may have."

    While searching the BallyAlley website for some additional information on Larry Leske, I found a quote from an article called In the Mind of Tom Defanti... Inventor of ZGrass by Suzan D. Prince. This was printed in the June/July 1982 issue of "Business Screen." Here's what Tom DeFanti says about Larry Leske:

    "About this time [1976 or 1977], another friend, Larry Leske, decided he could no longer afford to remain a student at the University [of Chicago] and went to work for Bally Manufacturing Co., the games producer. There he discovered the Bally Professional Arcade system, a fully assembled home computer game unit Bally planned to market to the public. Leske started programming on the Arcade, and believe me, he nearly knocked our socks off. Two others—Jay Fenton, a top programmer and developer of Bally BASIC; and Nola Donato, a language programmer-- and I, quickly wrote all the code for this new form Leske based on Grass. In 1979 Bally brought out the Arcade and its new software written in Z-Grass."

    Tom's remarks are not entirely accurate, for the BPA came out in 1978, and Bally never actually did release Z-GRASS. The full article can be read online:

    1. In the Mind of Tom Defanti... Inventor of ZGrass (Article) - In the Mind of Tom Defanti... Inventor of ZGrass by Suzan D. Prince. Business Screen (June/July 1982).

    Also, of note, there are several recorded phone conversations between Bob Fabris and Larry Leske.

    1. Larry Leske and Bob (Phone Conversation, Part 1) - Bob Fabris talks on the phone for about eight minutes with Larry Leske, who's been working on a programmable keyboard kit. [Arcadian volume 1, issue 8, page 55] It seems likely that Fidelity Electronics will take over the system, and they plan on possibly reviving the ZGRASS add-under in about six months. Larry has great respect for the engineering at Fidelity, and thinks it's likely they'll get out a quality product fairly quickly. Given this, Larry doesn't really want to compete with them, so the project is put on hold. [Arcadian, volume 2, issue 3, page 19]
    2. Bob Freeman and Bob (Phone Conversation, Part 2) - Bob Fabris talks on the phone for about fifteen minutes to Bob Freeman, who's been working on an S-100 adapter for the system [Arcadian volume 2, issue 2, page 11]. With Larry Leske losing interest on programmable keyboard work, Fabris is now particularly interested in this. Freeman is also thinking about things like a modem. But he's not moving at a fast pace unless there's enough interest to make it profitable. Fabris is planning on surveying the Arcadian readers on what they want. [Arcadian volume 2, issue 3, page 19]. Freeman has also programmed a system monitor ROM (it COULD be the "ADS System Monitor," but this is only conjecture), to be used for debugging assembler programs. Freeman wonders if Fidelity Electronics would consider speeding up the system's Z80, but Fabris says they're trying to cut costs on the board instead. They might consider a retrofit kit, though.

    They probably originate from around this era. It's intriguing to know that Bob reached out to Bally for help and maybe even guidance.
  • Light Pen Plans and Schematics - These plans by Leroy Flamm show how to build a light pen for the Bally Arcade/ Astrocade. The documentation refers to a tape with a program for the hardware. It can't be certain, but that program is probably Light-Pen Graphics Program, which was printed in Arcadian, 7.4 (Aug. 15, 1986): 68-69.
  • Guy McLimore Letter to Bob Fabris (June 14, 1979)

    Guy thanks Bob for his additions to Skyrocket (known also, on as Logo). According to the letter, it was Bob that added the rocket's vapor trail. Guy thanks Bob for his corrections to Checkers, but he's still having issues with the game.

    Guy is meeting with Bally's national sales manager [probably Jack Nieman] in Evensville on June 20, 1979. He plans to "get on his case pretty heavy about the keyboard expansion."

    Guys feels that "The potential is there for Bally to wrap up a large hunk of the personal computer market, but they are blowing it by holding up the keyboard, by failing to provide adequate documentation for Bally BASIC, and by falling to properly promote the system, service current customers, and provide software. I have just seen information on ATARI's new system, and Bally is going to lose customers to this new system if it doesn't provide the keyboard FAST."

    Guy is "encouraging all local Bally owners to write Bally encouraging a firmer commitment to expansion of the unit and demanding definite answers on the keyboard." He goes on to say "If all 600-plus ARCADIANS would write, maybe it would make a difference. Unfortunately, Bally is in the unique position of being able to well afford to ignore public demand, since their income from consumer products is only a tiny, tiny fraction of their total income. They just don't seem to give a damn one way or the other."

    Guy has "given Bob Fabris' address to two or three Bally owners in [his] area that [he] contacted through the Evansville Computer Club. One man [Guy] talked to [...] was frankly flabbergasted at all the information that was left out of the manual. [Guy] showed him &(9) [to control the left/right color boundary], the music oscillator and vibrato controls, ABS(X), the PEEK and POKE functions, ROM subroutines, etc. and [the man] nearly lost his teeth. He echoed the sentiments of so many others-- "Why doesn't Bally let people know what they have here?"

    Guy's light pen, which he talked about in his previous letter dated May 29'th, still won't work.

    Guys says, "This is unofficial and-- as yet-- not for publication, but I am negotiating with a major war gaming wholesaler in the East to supply him with game support software for the Bally system. He intends to become a Bally wholesaler, and will deal with Bally dealers by mail order if this goes through. I will be acting as his consultant on this project. Nothing is settled yet, but if it works out, we may be able to provide Bally dealers nationwide with a source of reliable software. If you wish, you may run in the ARCADIAN that I am interested in hearing from programmers who wish to license or sell their software. I can make NO PROMISES yet, though. It might help if I could give him some idea on these programs-- availability, reliability and such. Guy added a handwritten note here: "Again, P.S.: Hold off on this. Negotiating still proceeding, but slowly!"

    Guy makes a point that I've noticed over the years when reading the instructions for software published on tape. Guy says, ""So far, most of the Bally software I've seen is pretty amateurish in terms of presentation and documentation, while being surprisingly sophisticated in terms of actual program writing. What is needed is a tutorial on documentation, and my submission for such an article is enclosed. An improperly documented program is almost as bad an no program at all." [Unfortunately, I was unable to find in the Fabris Collection this documentation that Guy wrote.]
  • John Sweeney Letter to Bob Fabris (July 14, 2016)

    This is a double-spaced, nine-page type-written letter.

    John laments about the "new delay in the keyboard [add-under]." John gave up waiting for the add-under already and he has purchased a TRS-80 with the money he had set aside for the keyboard expansion. However, he still plans to use his Bally Arcade. In fact, he plans to get the two systems talking to one another.

    John has enclosed the schematic (for the main logic components) for a memory expansion that he created for his Bally Arcade. John assembled it with, he says:

    "wire-wrap on a 4 1/4" x 4 1/2" Vector board, mounted in a Radio Shack instrument cabinet. Actually, the mechanical problems of getting the signals out of the Bally, and of arranging the power supplies and cabinet were more formidable than any of the electronic or logic problems, save one. [which he doesn't mention]

    "As drawn, the schematic provides for up to 8 kilobytes of additional memory. At this moment, I have 3K installed, and the last 32 addresses at the top of the space are decoded to provide I/O & other special purposes."

    John goes into great detail about how his RAM expansion unit works. He provides a parts list too. Any listeners who are hardware hackers will probably be interested to read (or at least skim) this letter. This information was never published in the Arcadian newsletter, but I suspect that it was probably shared with some Arcadian subscribers.

    The hardware and software projects that were created by the Bally Arcade users in the late 1970s and early 1980s seem to fit very close with what homebrewers on 8-bit and 16-bit classic gaming systems and computers are creating today. The Bally system is hardly unique in this respect, even for its time of release. The Apple II, TRS-80, Commodore and S-100 users all were hacking away nimbly at their systems. The difference, to me, is that we don't look at the Bally Arcade system today as a computer, but rather as a game system in the same vein as the Atari VCS or, perhaps, the Intellivision. In 1978, one didn't bring home an Atari VCS and start adding RAM to it. Atari owners played Combat. They had great fun doing it (and so did I!), but maybe the Bally users had a type of fun that Atari game system owners couldn't touch: the fun of learning a system and creating with it.

Episode 5 of the Bally Alley Astrocast doesn't cover a game this episode. Chris has left as a co-host, so the review of The Incredible Wizard has been pushed to episode 6. Paul and I cover the Arcadian newsletter issues 5 and 6 (March and May 1979).  We cover a bit of feedback too. Paul and I discuss eleven letters to the Arcadian, dating mostly from the Spring of 1979.

Classic Letters

  • Tom Woods Letter (February 3, 1979) - February 3, 1979 letter to Bob Fabris from Tom Woods. The explanation of the "Onboard Calculator" in the March 1979 issue of Arcadian seems to be based on this letter. Bob seems to have expanded on the letter (by writing an example program).
  • George Hale Letter (February 14, 1979) - February 14, 1979 letter to Bob Fabris from George Hale. George Hale has used an ohmmeter to trace-out the 50-pin connector on the back of the unit. He has included an illustration of it. He's not sure he's 100% right, but he can see that every pin of the Z80 is present on the 50-pin connector. The Bally PA-1 Service Manual doesn't explicitly give this 50-pin information in an easy-to-read illustrated format (as George created), but the Bally Arcade's schematic does provide the necessary information for the information to be extrapolated. Also, the "third page" of this letter was written later. It is one-page letter to Charles Vollmer, Bally's National Service Manual. George explains that his letter to Bob crossed in the mail with his receiving the Bally Service Manual. He notes that most of the information he figured out is correct, although he numbered his 50-pin connector in reverse order from the one provided in the Service Manual.
  • Boyd Perlson (February 26, 1979) - February 26, 1979 letter to Bob Fabris from Boyd Perlson. Boyd, who seems to be an accountant, has developed a system on the Bally for keeping track of his chargeable time for each office client. He would like to know how he can make printouts of this, rather than copying the information off of the TV screen. This is just another example of the Bally system being used in situations that I wouldn't have ever expected!
  • James Wilkinson Letter (March 30, 1979) - March 30, 1979 letter to Bob Fabris from James Wilkinson. This letter talks about the experience that James had running GAME OVER from the February 1979 issue. He had to substitute line 50, which originally had X=3164, with X=3159. This discrepancy is caused by differences between versions of the Bally Arcade's 8K ROM. Craig Anderson (of Hoover Anderson Research & Design) eventually covers this problem in detail (nearly four years later!) in the January 1983 issue of the Arcadian in an article called Sneak Up and Bite Ya Department. He did this because "AstroBASIC" programs that he would write would work on some versions of the Bally Arcade and not on others.
  • Sneak Up and Bite Ya Department - This is a January 1983 article by Craig Anderson from the Arcadian which discusses the differences between different 8K on-board ROMs in the Bally Arcade/Astrocade.
  • Brett Bilbrey Letter (April 10, 1979) - April 10, 1979 letter to Bob Fabris from Brett Bilbrey. Brett sends corrections for a typing mistake that he made in SIMON (printed in the March 1979 issue). Many people had called Brett directly to find out how to fix the program. Brett had NO idea how they got his phone number, but he figured that it must mean that they're very interested, and he thinks that's good. He expects "many letters" to be coming (to, possibly?, Bob) about this SIMON mistake. Some of the issues that people had were not understanding common computer notation, such as that the asterisk means to use the "times" key, the difference between "O" and "0," and the "not equal" sign. He wants people to write to him, NOT call, as that "ties up" the phone line for his family. Brett tried transferring programs over the phone using his Bally unit, but he doesn't go into details about how he does it. Brett put up flyers in the Computer Center (at, I suppose, the University of Michigan?) to form a Bally user group. The first meeting will be May 12, 1979. This is probably the user group that became the Michigan BUGs (Bally User Group) and eventually called the Michigan AstroBUGS. Brett has included two programs: a SIN subroutine and OTHELLO. He says, "No mistakes, I hope!" Othello was never published in the Arcadian, but it was published fourteen months later in the June 1980 issue of the Cursor newsletter.
  • Brett Bilbrey Letter (April 14, 1979) - April 14, 1979 letter to Bob Fabris from Brett Bilbrey. Brett sends another correction for SIMON. He makes an odd-sounding, but understandable, statement when he says, "Many people have called in response to these errors. I am now writing to these people to help them with other questions and problems. So, if there had not been the mistakes, I would never have contact all these other Bally users in this area." "Also," Brett says, "many of these people now know of the user's meeting coming up May 12 at the Computer Center. The attendance is expected to be about 50 users." Brett notes that the April issue of BYTE, on page 193, has news called "Magnavox Files Suit on Microprocessor Video Game Patents." Included among the manufacturers they have filed suit against is Bally. As a follow-up to this 1979 news, I came across an 11-page Activision Case Reading by Ralph Baer, called "VIDEOGAME HISTORY: A little matter of record keeping." I am not sure when this was written, but it seems to be possibly from the late-90s or early-2000s. Mr. Baer states: "Let's examine the numerous stories floating around about the various videogame patent infringement lawsuits that were carried on by Magnavox and Sanders Associates, the owners of the seminal Baer patents and of the Baer, Rusch and Harrison patents. Those lawsuits started in the mid-seventies and ran all the way through the 1990's, the last of them for past infringement only, since the patents had long since lapsed. Bally, Seeburg, Mattel, Activision, Nintendo, Data East, Taito and others fought lengthy legal battles against the Magnavox/Sanders team in an effort to avoid having to pay license fees. They lost every one of those lawsuits, both in the initial actions in various Federal District Courts and finally, ignominiously, in the Court of Appeals. Then they had to pay up!" Brett also says, "One of the Arcadians [by which he means a subscriber to the Arcadian newsletter] who called, mentioned an article in a recent STOCK (I don't know the name) which states that Bally will be cutting funding to their home arcade program. This is said to be because of their casino opening in Atlantic City." I checked, and Bally's hotel/casino opened on December 29, 1979. Brett closes his letter with, "I am sorry for the mistakes in SIMON, and hope it did not cause too much trouble! But many users have learned something about debugging and a little about BASIC (sort of a learning experience). I will try to prevent further bugs from happening."
  • Videogame History: A Little Matter of Record Keeping - By Ralph H. Baer
  • John Collins Letter (April 12, 1979) - April 12, 1979 letter to Bob Fabris from John Collins. John says, "Many of the stores in our area have not been able to be resupplied with the Bally Arcades and have not been able to get the new tapes [cartridges], even after two months wait." This delay is so bad, in fact, that John asks, "Do you know whether they are still manufacturing the basic unit?" John is working on a version of HANGMAN, BOWLING and a special spelling routine. He'll furnish a copy when the bugs are worked out. Bob was having trouble with John's CHECKERS program (which was eventually printed in the May 1979 issue of the Arcadian), but John didn't know of any glitches. He hoped that Bob might be able to provide what the game board looked like and what level the game was playing when a bug occurred. John explains that the number printed on the screen tells the user that the computer is "still working." The number also provides the "type of decision or level the computer was at when it made its move." John describes in detail what the computer is doing as each number is printed on the screen. John dictated this hand-written letter to his wife, which I found rather surprising. He ends his letter with, "My wife's arm is tired, so I must close now." I found that pretty amusing.
  • Mary Stanke Letter (April 21, 1979) - April 21, 1979 letter to Bob Fabris from Mary Stanke. After reading Joe Sugarman's SUCCESS FORCES, I recognized Mary's name right away. Joe originally hired her as a secretary, and over the years she continued to move up in the company, eventually coming, it seems, his right hand man (woman?). This short letter informs Bob Fabris that JS&A can not provide him their "list of owners of the Bally, as JS&A has a policy wherein [they] do not divulge this type of information to anyone, nor would [Bob's] material be of interest to [JS&A] since [they] have discontinued offering the Bally Home Library Computer." So, now we know. By April, for certain, JS&A had given-up 100% on Bally!
  • David Stocker Letter (April 23, 1979). - April 23, 1979 letter to Bob Fabris from David Stocker. David submits two of his tapes to Bob Fabris. These tapes contain a total of 23 programs. It seems that David took some of the programs from the Bally BASIC manual, changed them up a bit (or a lot-- I don't know) and sold them on tape and as program listings. David would like Bob to inform the "Arcadians" about his programs, which he sells as two sets for two different prices. If you buy one set, then the cost is $8 (or $4 if you return the tape). If you buy both sets, then the cost is $10 (or $6 if you return the tape). This returning of the tapes seems like it would have really complicated matters and been extremely labor intensive. There are three pages of hand-written instructions for some of the programs. Both sets of David Stocker BASIC programs were added to on March 13, 2015. Since these were available on tape-- they are some of the earliest third-party programs available on tape for a game console. Mr. Stocker even beat Activision to the punch, so it's too bad this stuff isn't up to say, "Pitfall" quality. The instructions for these two tapes provide the hand-written BASIC listings for each program. This was common even in the early days of the "Arcadian" newsletter. Mr. Stocker's script is quite small (or maybe it was reduced), plus the quality of the original paperwork was also difficult to make out, which makes these programs quite hard to read. The first tape is called "Set I - Games and Fun." It contains eight programs. The second tape is called "Set II - Video Art." It contains fifteen video art programs.
  • John Perkins Letter (April or May 1979) - April or May 1979 letter to Bob Fabris from John Perkins. The Bally Astrocade only has 4K of RAM. This may seem like a plenty of RAM when compared to, say, the Atari 2600 (which only has 128 bytes of RAM), but 4,080 bytes of this 4096 total bytes of RAM is all dedicated to screen RAM. This makes up the entirety of the Astrocade's 102x160 bitmap screen (the remaining 16 bytes of RAM is called the scratch pad). Things begin to get really confusing when you consider that the BASIC cartridge doesn't contain any of its RAM, and yet it somehow (almost magically) it provides the BASIC programmer with 1.8K of RAM to program the system. How is this done? John Perkins wrote a hand-written letter to Bob Fabris which provides some of these answers. This letter is the background and research for which the tutorial in the May 1979 Arcadian called "Screen Operations" by Mr. Perkins is based. The tutorial, as printed, condenses the information that John provided to Bob. The tutorial also excludes a short example program that John wrote that shows how to display four colors on-screen at once. The letter explains how the BASIC program is hidden on the screen in plain sight by taking advantage of some of the Bally Arcade's Left-Right Color Boundary. In the early 2000s, I had a phone conversation with Mike White. I remembered that he said this article explained the details correctly, but that is was a bit muddled with some of its information. I couldn't remember exactly what Mike meant by this, so I emailed him back in February and he provided me with a full explanation. Mike says, "John Perkins declares the program to be "stored in the even bits" with the picture using the odd ones. This is "computer geek" thinking and not what an algebra teacher would say! In algebra the digits are numbered 1-2-3-4-5-6-7-8! While in computers it's 0-1-2-3-4-5-6-7! Now, turned around to their natural format they become; 8-7-6-5-4-3-2-1 and 7-6-5-4-3-2-1-0 respectively! Therefore, hex 55 (01010101 binary) is EVEN and hex AA (10101010 binary) is odd in a computer ONLY! If you did this on a math test you would flunk out, and may be sent to the principal's office!"
  • Doug Marker Letter (September 1979) - September 1979 letter to Bob Fabris from Doug Marker. Doug is a "computer specialist working on IBM compatible machines." It's notable that since this letter was written in 1979, Doug must have been working on IBM compatible mainframe computers, as the IBM personal computer wasn't released until August 12, 1981. Doug started his career as a hardware engineer, advanced to a software engineer and eventually became a Systems Engineer for IBM. This type of in-depth knowledge of hardware and software is a common thread among quite a few letters in the Bob Fabris Collection: many users had technical backgrounds. What sets this letter apart from so many of the other letters is Doug's location: he lives in Auckland, New Zealand! Doug doesn't explain how he came across the Bally Home Library Computer in New Zealand. Perhaps he ordered it directly from JS&A from the original September 1977 ad in Scientific American. What's significant about this letter is that there is no PAL version of the Bally Arcade system. Thus, Doug is using an NTSC system in a PAL territory. This isn't unheard of (many collectors do it today), but it's quite unusual (especially for 1979). Doug says, "I am presently building a PAL modulator so that I can get color. The USA has a different color transmission system called NTSC, so I have to modify my Bally." He talks about working on upgrading his unit's RAM internally to 8K or 16K, but won't work on this until he has the PAL modulator working correctly. Doug has done some exploration on his own of the built-in routines of the 8K system ROM, but he proposes a project that he would find very useful: a list of all of the built-in routines in the "resident ROM and the BASIC ROM." Doug goes into some depth on what he has discovered on his own about how the interrupts works on the Bally Arcade. Doug's final discussion is about changing the speed of his Bally Arcade unit, providing that the custom chips can handle it. [Which I don't think that they can do.] He intends to replace the basic timing of the microcomputer by replacing the master oscillator, which he has to do anyway so that he can get the PAL color working correctly. He plans on replacing the 14.31818 MHz with a 16Mhz crystal oscillator.
  • Comments from Tom Meeks - Tom Meeks worked at Astrovision. Among the questions that he answers in this compilation of comments from the Bally Alley Yahoo Group are if any PAL Astrocade systems exist.


Aug 14, 2016

Episode 4 of the Bally Alley Astrocast covers the Bally Arcade/Astrocade cartridge game Sea Devil and the BASIC type-in game (published in the Arcadian newsletter) The Pits. Chris and I discuss, as always, what we've been up to lately. Paul and I cover the Arcadian newsletter issues 3 and 4 (January and February 1979).  We cover a bit of feedback too (we could always use more though-- so keep it coming to us). Paul and I discuss seven letters to the Arcadian, dating from late 1978 and early 1979. The show ends with a short tune called Golden Slippers played from a type-in program called Player Piano from the Bally BASIC manual

  • Game Over (Program) - By Tom Wood. "This routine will print "GAME OVER" depending on which version of the Bally Arcade that the user has." This 300-Baud Bally BASIC program can be loaded into BASIC using the 300-Baud tape interface code.
  • Game Over (Article) - By Tom Wood. This pdf document was excerpted from the Arcadian. This is the program's explanation, the BASIC loader, the Z80 machine language source
  • BASIC Zgrass--A Sophisticated Graphics Language for the Bally home Library Computer - By Tom DeFanti, Jay Fenton, and Nola Donato. This article was printed in Computer Graphics, 12, no. 3, (August 1978): 33-37. Abstract: "Home computer users are just now discovering computer graphics. Modest extensions to BASIC allow plotting but not much more. The Bally Home Library Computer, however, has hardware to aid implementation of video games. Custom integrated circuits working on a 160X102 pixel (2 bits per pixel) color television screen allow certain forms of animation in real time. To give this power to the user, BASIC Zgrass has been designed and implemented. It is an extension of BASIC that allows parallel processes, picture objects that move, scale and group together as well as several drawing modes. There are also software controls of a three-voice music synthesizer, interactive input devices, a film camera and an IEEE bus interface. We will concentrate mainly on the language design for making it all easy to learn and use."
  • Bally BASIC Hacker's Guide - By Jay Fenton. This was the 1979 supplement written by Jay Fenton that went along with the Bally BASIC manual. It's full of all sorts of goodies, most of which found their way into the "AstroBASIC" manual... but not everything.
  • Bally Arcade - More than Fun - By Graham M Wideman and Mark J Czerwinski. Electronics Today, November 1978. Paul and I refer to this article as "Bally Arcade: Game or Computer," but that's only the title on the cover of the magazine. This article covers the Bally Arcade. Although the page numbers are not consecutive in this scan, the article is complete (full page advertisements were removed). The article is notable because it assumes a basic level of technical knowledge and includes photographs of the internals.
  • Chain Store Age 'Catalog' - This 'catalog,' from June 1978, was put together by Bally to promote the Bally Professional Arcade to salespeople. This is a full-color 'catalog' that is a large download (9MB). It is 8 1/2" x 11" and is sixteen pages long. I love the 1970's style art!
  • Bally Programming Keyboard - Color picture of the unreleased "programming keyboard." The Bally Arcade system sits on top of this "add-under."

Classic Letters

  • Letter to Bob Fabris, From Brett Bilbrey (December 11, 1978) - Brett was a mainstay of the early issues of Arcadian and Cursor. He went on to write two Astrocade cartridges (ICBM Attack and Treasure Cove), contribute to the "AstroBASIC" manual and work for Action Graphics (as well as contribute to the Bally community in many other ways). Later, Brett worked for Apple. This eight-page letter shows a hardcore user's enthusiasm for the Bally Arcade.
  • Star Trek - By Brett Bilbrey (and/or friends). Brett did not 'write' the Star Trek game. He either typed it in from the book 101 BASIC Games or one of his friends that Brett started Spectre Systems with did it. This 300-Baud Bally BASIC program can be loaded into BASIC using the 300-Baud tape interface code.
  • Star Trek (Docs) - Instructions for the above program.
  • Byte Magazine (December 1978) - Many articles dedicated to Life. While none of these articles/programs are specific to the Bally Arcade/Astrocade, the manual for Life by Jay Fenton does directly lift quite a bit of material from that issue of the magazine.
  • Interact Model One Computer - The Newman Computer store suggests potential Bally Arcade purchasers buy the Interact Model One instead. (
  • Letter to Bally Arcade Customers, From Joseph Sugarman (May 1979) - Joe Sugarman, the president of JS&A, claims that the company "had spent hundreds of thousands of dollars in advertising to obtain our sales." That's a lot of money, which makes it hard to believe this claim. However, in the early 70s, when JS&A began, full-page ads in the Wall Street Journal cost about ten-grand (says Joe in his 1980 book, Success Forces), so perhaps this high-dollar advertising figure is possible.
  • Letter to Bob Fabris, from Glenn Pogue (Jan 22, 1979) - Glenn says that if a user complains about the unit's name change, then Bally will send a "tag" to those users who request one that says "The Bally Computer System." This letter has a list of release dates (month and day) for Bally games, including some that were never released at all (including Checkers, Desert Fox, Astrology and Drag Race/Desert Fox
  • Bally Dust Covers Pictures - Each time the Bally system's name was changed, the dust cover reflected the new name.
  • Unit Label Variations - Lance Squire does an excellent job explaining the different labels on the dust covers of the Bally units. He also gives an approximate rarity level for each label.
  • Letter to Bob Fabris, from Guy McLimore (January 29, 1979) - Guy is a Bally Arcade dealer for ABC Hobbycraft. Guy has popped up on the Bally Alley Yahoo group from time to time. In this letter, Guy says that he gets more information from the Arcadian newsletter than he can get from Bally-- and he's a dealer! He mentions several programs he's working on. He suggests that Bally should make a second, more detailed (I presume) version of the Bally BASIC manual for "the really rabid Arcade freak." In a way, Jay Fenton's Hacker's Manual was this second "book," but it was only about twenty pages long and probably wasn't widely available.
  • Fantasy Game Package - By Guy McLimore. 1979. There is an advertisement for this program in Arcadian 1, no. 7 (Jun 15, 1979): 54. A fantasy game package for advanced players is available for those who enjoy the Dragon/Dungeon type of operation. The package includes: Dungeon Grafix I and II, Fantasy People and Multidie.
  • Arcadian Logo - By Guy McLimore. From Arcadian 2, no. 1 (Nov. 29, 1979): 3., "Logo shown at the head of page one is based on an idea by Guy McLimore, and embellished by myself. If you'd like to see it in action (literally) and in living color, the program is included."
  • Letter to Bob Fabris, from Jim Unroe (December 27, 1978) - Jim canceled his order with JS&A after waiting for long time and then he got an Arcade unit right away from another dealer (yes, even at the end of 1978, JS&A wasn't getting enough units from Bally to fill orders). He's having issues with his unit (it sounds like overheating). He notes that you can have commands executed directly from tape rather than being loaded as a program line. This is one advantage of Bally BASIC over "AstroBASIC." Jim talks about wanting to create an elaborate alarm system using his Bally Arcade.
  • Letter to Bob Fabris, from Joe White (November 26, 1978) - Joe talks about his general experiences using the Bally to program in BASIC. Joe's son, Greg, wrote Bally Trek, which is based on Erik Mueller's Star Trek for MINOL - Tiny BASIC.
  • Bally Trek - By Greg White. 1979. Unpublished Arcadian submission. Bally Trek is based on Erik Mueller's Star Trek for MINOL - Tiny BASIC. Bally Trek follows a popular style of game program from the 1970s era. Other examples on the Bally Arcade/Astrocade include Space Chase by WaveMakers and Star Trek/Starship Command by Esoterica. This 300-Baud Bally BASIC program can be loaded into BASIC using the 300-Baud tape interface code.
  • Letter to Bob Fabris, from John Sweeney (January 22, 1979) - John requests Executive Software by Tom Wood because he is trying to write an assembler for the Bally Arcade. This is very early in the Bally Arcade's history to be working on something like this. There is no evidence that this assembler was created, but General Video Assembler (which required a RAM expansion) was eventually written and released on tape in 1982 by Dave Ibach and Steve Walters (General Video). Dave used this assembler to write his centipede-inspired, cartridge game, Sneaky Snake. John talks about safe places for assembly code in Bally BASIC (he uses the editor/buffer). He recommends some articles/books for Tiny BASIC information.
  • General Video Assembler with Examples (Programs) - By General Video. The General Video Assembler is made-up of four programs which include: General Video Assembler Collector, General Video Assembler Pass I, General Video Assembler Pass II, and General Video Assembler Text Editor. Also included are sample programs (both as assembler code and in their final assembled form), Flying Witch Sample, Logo Sample. This 2000-Baud "tape" runs from "AstroBASIC and it requires extra RAM.
  • General Video Assembler (Docs) - By General Video. Written by Dave Ibach. Documentation for a Z80 assembler that runs on the RAM-expanded Bally Arcade.

Episode 3 of the Bally Alley Astrocast covers the cartridge game Crazy Climber and the BASIC game (released on tape) Missile Defense. Chris and I discuss what we've been up to lately. Arcadian newsletter issues 1 and 2 (November and December 1978) are covered in detail.  We discuss a bit of feedback. Chris, Paul and I go discuss the very first ad for the Bally Home Library computer (from September 1977). I read from a few letters that JS&A (the mail order company that originally sold the Bally Home Library Computer) sent to customers. The show ends with a one-minute rendition of the Happy Days theme song.

Full Bally Alley Astrocast - Episode 0 Transcription

Adam: Hi, everybody.  My name's Adam Trionfo, otherwise known as BallyAlley on the AtariAge forums.  And I'm here with...

Chris: Chris, otherwise known as "Chris."

Adam: And you're listening to the zero-ith episode of Bally Alley Astrocast.  See, I barely know the name of it yet.

Chris: I think me and Adam believe that we thought up the name Astrocast ourselves, and we came to find out that there had already been one, it just hadn't been started. And I guess it was Rick and Willy (I think it was only those two).

Adam: Yup.

Chris: And, it kinda sat there for a year.  Hopefully they will be contributing to Adam's podcast here.

Adam: I don't think of this as "Adam's podcast." (And I just used finger-quotes, sorry about that.)  This is our podcast.  Chris and I are recording this right now.  Also, Paul Thacker, who is a regular of the Bally Alley Yahoo group (which we can talk about at a later time).  We're hopefully going to do this together at some point.  I wanna sound natural as possible for this podcast.  So, I'm trying to not read anything off a piece of paper.  I don't like the sound of my voice, and the fact that I'm letting you hear it means that I love you guys.

Chris: It's a great level of trust he's exhibiting, you guys.  Plus, I would immediately take his script away from him if he had one because...

Adam: Oh, thanks, Chris!

Chris: Yeah.  Extemporaneous is more fun to do, and I think it's more fun to listen to.

Adam: So, in saying that, we do have some notes we wanna talk about. For this episode we wanna basically go over what we want to cover.  Which is what people seem to do in these episodes.  Saying, "Hey, there's gonna to be an episode of a podcast called 'this'."  And, that's what we're doing here.  So, here's what we're going in our podcast number zero.

Chris: It was always funny to me, like oxymoron, like: episode number zero.

Adam: Right.  Right.

Chris: Let's go negative one.  Let's be rebels.

Adam: You may or may not know what a Bally Arcade, or an Astrocade, is.  It was a console that was developed in about 1977.  It was released in 1977, but the first units were not actually shipped, for various reasons, until January 1978.  And very few people got them.  They were first released by catalog-only, by a company called JS&A.  Those systems had overheating problems.  Most of them were returned-- or many of them were returned.  JS&A only sold approximately 5,000 units (so it says on the Internet).  I don't know where that number is quoted from.  I've never been able to find the source.  Bally eventually started selling them through Montgomery Ward.  Now, Bally also had something called the Zgrass that it wanted to release.  This was going to be expanding the unit into a full-fledged computer.  This never was released.  The Bally system itself did not come with BASIC, but it was available nearly from the start.  Many people used it.  A newsletter formed around it called the ARCADIAN.  The system has 4K of RAM and it does not use sprites, but it could move object just as well as the Atari [VCS] and other systems of its time period.  It could show 256 separate colors and through tricks and machine language, it could show all of them on the screen at once, but not normally in a game.  Although there are a few screens that did it (but not actively during a game).  The system is fun to play... if you can find one that works.  If you don't already have one, you're going to discover (if you go searching for one) they're not inexpensive.  They're becoming pricey on the Internet because of the overheating problems they had, since the beginning (with the data chip), you will find that if you own [should have said buy] one now, you're getting a unit that "has not been tested," which means, of course, it is broken.  If you find one on the Internet that says, "Not tested," please, do not buy it.  Just let it stay there and let someone else buy it.  And, when they get it and it doesn't work, if they're surprised then they did not read the "Bally/Astrocade FAQ."  We'll go into much greater depth about this system in the next episode.  I just wanted to let you know that's the system we'll be talking about.  It has a 24-key number pad.  It has a controller that is-- is it unique?  Well, I think it's unique.

Chris.  Um-hum.

Adam: It has a paddle built into the top knob.  It's a knob-- it's called.  And it has a joystick-- an eight-directional joystick.  It's built like a gun controller-style pistol.  It's called a "pistol grip."  It's sorta shaped like one, if you picture a classic arcade-style gun, and then just cut off the barrel.  That's basically what you have.  Something that was originally mentioned, and I think Bally might have called it that for two years, are Videocades.  Videocades are the cartridges.  These were actually also referred to as cassettes.  These are not tapes.  These are about the size of a tape, but they are ROM cartridges.  In the beginning they held 2K and later on they held 4K for Bally.  Astrovision, or Astrocade, Inc., later released some 8K games in about 1982.  Those were usually considered the best games on the system because they had more ROM to spare and to put more features into the games.  Now, BASIC was available from about the third or the fourth month after the system was released to the public.  It was originally called BALLY BASIC.  It did not come with a tape interface, but one was available for it.  BALLY BASIC cost approximately $50.  The tape interface, which could allow the user to record at 300-baud... which is pretty slow.  To fill the 1.8K of RAM, which is available to BASIC, would take about four minutes to load a complete program.  Better than retyping it every time, isn't it?  But, it's not a great speed.  Later on, the system (when it was rereleased), it actually came with BASIC.  It was still called BALLY BASIC, but today to differentiate it from the original BASIC cartridge, most people call it ASTROCADE BASIC or AstroBASIC.  The reason for this is the later BASIC has a tape interface built into the cartridge itself.  This can record and playback information at 2000-baud, which is an odd number because it's not a multiple of 300.  Because when 300-baud tapes were speeded up by a newer format later, they were 1800-baud.  Tapes were available, which meant the user community was able to grow because they could share programs.  It was sometimes a problem for them because I could record a program on my tape drive and I could send it to you in the mail.  And you'd say, "It's not loading.  It's not loading!"  Well, you'd sometimes have to adjust your read and write heads to match it.  Imagine having to do that today?  To having to... uh, I wouldn't want to think about doing it.  So, even if you can believe it, with that kind of an issue, with users having to adjust their tape systems in order to load programs sometimes, there were commercially released tapes.  These have been archived and are available and you can download them from

Chris: So, the play and record head on anybody's tape recorder... there was the possibility that it had to be adjusted to play a tape his buddy had sent him because he had a tape recorder with differently aligned play and record heads in it-- I mean, that's something else!

Adam: Now, the recorders that were normally used were called shoebox recorders.  These were recommended.  If you tried to record to a home stereo, maybe Chris can understand this better and tell me more about it in a later episode, but you really couldn't record to one and then get that information back.  I'm not sure why.  But, the lower quality that was available from the low-end tapes that were less expensive were actually better.  Just like there were better audio tapes available, which you should not have used for data because... because, I don't know why!  So, ideal podcast length.  In my mind I see about an hour, or an hour and a half.  While I listen to many podcasts, among them Intellivisionaries (and others) that are not short.  And, as has been discussed on the Intellivisionaries, there's a pause button.  So, if somehow we do end up at five hours, please understand that there is a pause button.  If we end up less, you don't need to use the pause button.  Isn't that great?  Technology... right?

Chris:  Well, a very good idea that you had was obviously to conduct interviews with some, I guess, what, Bally game writers, people who are really knowledgeable about it.

Adam: Well, there's quite a few people I'd like to interview.  If we can find people from the 70s and the 80s, and even now, there's some people who have written some modern games-- at least written some programs for the system.

Chris: It would help if they're still around. Yeah.

Adam: Something that's interesting, that I wanna use, is that there's actually recorded interviews that we have from the early 80s and late 70s of phone conversations that Bob Fabris did (from the ARCADIAN publisher).  There was a newsletter called the ARCADIAN and it published for seven years (from 1978 to 1984 or 85, depending on how you view things a bit).  He recorded some conversations with some of the more prominent people of the time.

Chris: That's cool!

Adam: We've made WAV files of those or FLAC files and they're available for download (or many of them are already) from BallyAlley.  But, it might be interesting to take out snippets from some of those and put them in the show.  I hadn't thought of that before, but that's why we're going over this.

Chris: Yeah.  Absolutely.

Adam: Right.

Chris: That's really cool.  We say Bally Astrocade, like we say Atari 2600, but it was never actually called the Astrocade when Bally owned it.

Adam: Not when Bally owned it; no.  But after it was resold they had the right to use the name Bally for one year.

Chris: Oh.

Adam: And Astrovision did do that.  So, for a short time, for one year, it was known as the Bally Astrocade.  And it actually was called that.

Chris:  Oh.  Okay.

Adam:  But, somehow that name has stuck.  And that is what the name is called.  And many people think it was called that from the beginning.  It was originally released under a few different names, which we'll get into at a later date.  I think of it... I like to think of it as the Bally Arcade/Astrocade.

Chris: Yeah.

Adam: It depends on how you look at it.  Sometimes I go with either.  Sometimes I go with both.  Sometimes I call it the Bally Library Computer.  It just on how I'm feeling at the time.  So, we also don't plan to pre-write episodes.  You might have noticed that by now.  We do have a list that we're going by, and we do wanna use notes, but reading from a script is not what I wanna do.  I don't want to sound dry and humorless.  I like to have Chris here making fun of me-- well, maybe not making fun of me, but, you know, Chris here... helping me along to give me moral support.  And I enjoy that I'll be doing this with him, and hopefully Paul as well.

Chris:  It is strange for you and I to sit around talking about old videogames.

Adam: Oh... isn't it!  Isn't it though!

Chris: [Laughing]  Some of the sections that Adam has come up with are really interesting.  They sound like a lot of fun.  And what's cool is that they are necessarily unique to a podcast about the Bally console.  For instance, we were talking about the ARCADIAN newsletter.  There's going to be a segment-- it will probably be every episode because there is a LOT of source material.  This segment will delve into ARCADIAN notes and letters that did not make it into the published newsletter.  It's kind of a time capsule.  In some ways it will be fascinating even for people who don't know a lot about the Bally Astrocade because what you're getting is correspondence from the 70s and 80s, before anybody really knew what was gonna happen with the 8-bit era, you know?

Adam: There's material in the archives.  All of this material is from Bob Fabris.  He was the editor or the ARCADIAN.  Two people, Paul Thacker and I, we bought that collection from an individual who had bought it in the early 2000s directly from Bob.  It was never broken up, so it's all together in about eight boxes-- large boxes-- all in different folders.  Bob Fabris kept a really, really detailed collection and in great order.  He kept it in that shape from 1978 until, what?, about 2001 or 2002 when he sold it.

Chris: Wow.

Adam: So the fact that it survived and then someone else bought it and didn't want to break it up and sell it is pretty amazing to me.  We were able to pool our funds together, Paul and I, and purchase it.  All of it has been scanned.  Not all of it is available.  Oh, and by the way, BallyAlley, in case there are some listeners who don't know... BallyAlley is a website that I put together.  It's mostly from the archives of the ARACADIAN.  But, there's a lot, a LOT, of interesting material there.  If you're interested in the Bally Arcade, you should check it out.  It's

Chris: Adam is being kinda modest.  He's done a lot of work on this.  You're gonna find archived materials that will make your eyeballs pop out of your head.

Adam: [Laughing]

Chris: You know, he's...

Adam: If you saw Chris, then you'd know that's true.

Chris:  Yes.  Absolutely.  I'm recording blind.  You know, he's very picky about high quality scans (as high as possible only).  He's vey meticulous about it.  And I definitely recommend that you guys visit BallyAlley period com.  I know it's a lost battle; humor me.  They're not dots.  All right... anyway.

Adam: All right.  Cartridge reviews.  The Bally Arcade... it has a lot of perks, one of them is not it's huge library of games.  I take that back.  It has a huge library of games.  Many of them, as some people may not even know who are listening to this, were released on tapes.  But the vast majority of games, that people would think of as the console games, are cartridges.  The Bally could "see" 8K at once.  It didn't have to bankswitch or anything like that in order to do that.  There was never a bankswitching cartridge that was released for the Bally.  At least at that time.  Since the library is so small, I'm not sure if we're planning to cover a game per episode, or since we plan to cover all of the games (and there are certainly less than fifty, if you include prototypes) and some of them are not games.  Some of them were... BIORHYTHM, so that you could know when it would be a good time to get it on with your wife to have a baby.  You know... [laughing] So, if that's what you wanna talk about and listen to... write us and say, "That's sounds great.  I want you to tell me when I can get my wife pregnant." [laughing]  The other day my wife was taking a look at a game I was playing for a competing console, the Atari 8-bit game system.

Chris: I thought you were gonna say the Arcadia.

Adam: No, not the Arcadia.  I was playing a SUPER BREAKOUT clone.  She took a look at it and didn't know what it was.  I said, "You know, it's a BREAKOUT clone."  She's like, "I don't know what that is."  I said, "No.  Look at the game for a minute.  It looks like BREAKOUT."  And she still didn't get it.  And I said, "Okay, so you're gonna have a ball that bounces off a paddle and it's gonna hit the bricks up above."  And she goes, "I've never seen this before."  And I said, "Okay.  You've heard of PONG, right?"  She's like, "Well, yes I've heard of PONG."  I said, "It's that."

Chris: [Laughing] It's that... except better.  Between you and all of the people you're in contact with from the Bally era, and people like Paul.  People who actually wrote games back then...

Adam: Um-hum.

Chris: Information about how the console works and its languages and stuff... is that pretty-much taken care of, or are there more mysteries to be solved.

Adam: There's some mysteries.  The neat thing about this system was that even in the ARCADIAN, in the early issues, you could get access, for like $30, to the photocopies that were used at Nutting Associates.  These are the people who actually designed the Bally system for Bally.  They did arcade games-- we'll go more into that in another episode.  This information was available to subscribers... almost from the get-go.  So, if you wanted to have a source listing of the 8K ROM, you could get it.  Of course, it came with a "Do Not Replicate" on every single page, but... it was... you were allowed to get it.  You could purchase it.  It was freely available and it was encouraged for users to use this information to learn about the system.

Chris:  The reason I ask is that I'm wondering what the next step is.  Whenever I think of this console... do people refer to it as a console or a computer, by and large?

Adam: A game system in my eyes.  I mean, it's a console.  People don't think of it as a computer.  No.

Chris:  I'll start over.  Whenever I think about this system, what usually comes to mind is the fact that it is unexploited.  And that is perhaps the, not quite an elephant in the room, but that is the only real disappointment about the Astrocade is that there are these amazing, vivid, brilliant, games.  I mean, the arcade conversations on the Astrocade are, for all intents and purposes, arcade perfect.  This was a superior machine.  And yet, players were teased with a handful of astonishing games and then that was it.  So, "what could have been," comes to mind for me a lot.  And the phrase tragically untapped.  What I'm wondering is why nobody has brought up the initiative of making new games.  The last two were arcade conversations.  They were not original, but they are, of course, phenomenal.  I mean, two of the best titles, you know are WAR (which is a conversion of WORLORDS) and, of course, CRAZY CLIMBER.  You were in charge of all the packaging and EPROM burning for those.  I'm not saying...

Adam:  Partially.  Partially.  For all of one of them I was, but the other one was handled by a man name Ken Lill.  I did... I came up with the package design and stuff like that, and made a lot to make it happen.  But, I didn't program the games.  No.

Chris:  Right.  But I mean, somebody else did the coding, but didn't you have all the cartridge shells.  And you were burning...

Adam:  I made sure it all happened.

Chris:  Okay.

Adam:  Yeah.  I mean, I didn't do all the work though.

Chris:  Okay.

Adam: It helped that I was there.  Put it that way.

Chris:  We're talking about CRAZY CLIMBER, mainly, right?  Because you helped with WAR as well.

Adam: Yeah.  I did both.  Yeah.

Chris.  Okay.

Adam:  Um-hum.

Chris:  And you wrote some of the back of the box copy.

Adam:  I did all of that.  Yeah.

Chris:  As expensive and limited as such a run would be, that's not really quite what I'm talking about.  As having to go through all that to give people physical, boxes copies, I guess.  Another reason why people might not have written anymore Astrocade games is that the relatively few surviving consoles could be prone to overheating themselves to death at any time.  But, then there's emulation.

Adam: Right.

Chris:  MESS is all that we have, and it's not perfect.  So, wouldn't that be the first step for somebody to write a really good Astrocade emulator?  I would do it, if I knew how.

Adam: Yes.  If there's one of you out there who's like, "Who couldn't write an Astrocade emulator?"

Chris: Yes.

Adam:  Please, would you do me a favor and send that to me tomorrow?

Chris:  It's time.  ...Tomorrow... [laughing]

Adam: Something that I wanna get at is that MESS does work for most games.  There are a few that don't work.  Some of them used to work and now they're broken.  MESS was updated to make it "better," and now some games don't work.  I don't understand why that happened.  The biggest drawback to MESS is that is doesn't support the tape.  It doesn't support-- it supports BASIC, but you can't save or load programs.  And since they're hundreds... there's probably over 500 programs available.  And there's... many, many of those have already been archived and put on  So you can try them out on a real system, but not under emulation.  And it's quite easy to use under real hardware.  We'll get into that at another time too.

Chris: In terms of cartridge reviews.  And I'm only going to say this once.  Thanks, by the way, for saying that this is our podcast

Adam: Sure.

Chris:  I thought I was just being a guest.  

Adam:  No.  No... you're just a gas.

Chris:  I'm just a gas.  So, should I help you pay for the the Libsyn?

Adam: I think we'll be okay.

Chris: All right.

Adam: All of our users are going to send donations every month.

Chris:  Oh, that's right.

Adam: [Laughing] Just kidding there, guys.

Chris:  So, I'm just going to say this once.  And you're welcome.  Review is a word I have a problem with when it comes to my own, well, stuff I write.  But now, apparently, stuff I talk about.  Because I associate the word review with critics.  I think I was telling you the other day, Adam...

Adam:  Yes, you were.

Chris:  I would never hit such a low level of self-loathing that I would ever call myself a critic.  Talk about a useless bunch.  For me they'll be overviews.  It's very picky.  Very subjective.  It has nothing to do with anybody else.  You wanna consider yourself reviews-- totally respect that-- but I don't do reviews.  So, either that, or I'm in some sort of really intense denial.  But, personal reflections on games, reviews leaves out... when you call something a review, it leaves out the fact that taste is subjective.  It's a personal thing.  I can't review food for you and have you think, "Oh, now I like that food I used to hate."  One's tastes in games, music, etcetera is just as personal.  So, Adam was saying that there's so few of them, that we're not going to cover a game every episode.  So, what we're going to do is alternate, so that you don't go completely without game "content" (isn't that a buzzword, a frequent word online now: "content").

Adam:  That is.  Yeah.

Chris:  Everybody wants content.  I gotta table of contents for ya.  We're going to alternate actual commercial cartridge games with commercially available tape games and even type-in programs, because there were a lot of good ones.

Adam: Most of them were written in BASIC.

Chris:  Which is just awesome to me.

Adam:  Yeah.

Chris:  We were thinking of alternating the games stuff I was just talking about with this:

Adam:  The Astrocade system, well, the Bally Arcade system, as it was originally designed for home use, it had two versions.  There was an arcade version, which came out in 1978 with the first game, Sea Wolf II in the arcades. And there was the version that was released for the home.  It had 4K of RAM, while the version in the arcades had 16K (and some additional support), but they use the same hardware (like the data chip). They're so similar in fact, that many of the systems games were brought home as cartridges.  They don't use the same code.  They are not-- you can't run code for the arcade and vice-versa.  You can, for instance, take a Gorf and run Gorf on Wizard of Wor hardware.  It'll look the wrong direction, but you can do that.  The systems are very similar in that respect.  But, you can actually take an Astrocade (and it has been done before) that is a 4K unit, and actually do some fiddling with it, change the ROM a bit, give it more RAM (there's more that you have to do)-- there's actually an article about it, it was written in-depth (it's available on BallyAlley, the website).  And you can make it into an arcade unit.  It wouldn't be able to play the arcade games, but it would have access to 16K of RAM and that sort of thing.

Chris:  When you say Sea Wolf II, you mean the arcade game was running this hardware that you're talking about.

Adam:  Right.

Chris: Much of which was also in the console.

Adam:  Yes.

Chris:  Okay.  And that goes for WIZARD OF WOR, GORF, SPACE ZAP.  Well, that explains why there are so many arcade perfect home versions.

Adam.  Um.  Right.  They don't share the same code, but they are very similar.  The Hi-Res machine could display, in what was considered then a high resolution.  The Bally display in 1/4 of that resolution.  I think perhaps will have the first episode cover specifically the hardware of the astrocade.

Chris: So, you are saying that this segment would cover the arcade games that used the astrocade hardware, and I find that really, really interesting (because I never knew that).  I thought that they were just, you know, very similar and some of the same people created the home versions, but I didn't realize that... I never realized they were so close.

Adam: So, another segment that we plan to do is called, "What the Heck?!?"  It's going to focus on unusual hardware and maybe even released items, but something that, while it was released through the Arcadian newsletter or perhaps the Cursor newsletter (and maybe even one of the other small newsletters that were around for a short time for this system exclusively).  When we're talking about a released product here, we are probably talking about in the tens-- the twenties.  I mean, new homebrew games get a wider release than games that are considered released back then.  Maybe not the games, but hardware peripherals.  There was something called the Computer Ear which could do voice recognition-- sort of.  But the software for that isn't available, I don't think… maybe it is.  I have the hardware, but I've never tried running before.

Chris:  We're also gonna-- I say "we," even though Adam's knowledge about, well pretty-much all of this stuff is much greater than mine, hoping to cover the Zgrass keyboard/computer.  Is that a fair description?

Adam:  Yeah.  That's what you would read on the Internet about it.  And if you can call that true, then that's what it is.

Chris:  Right.  And not just on the WikiRumor page.

Adam:  Yeah.

Chris:  It's a very unusual system and it's worth learning about.  See, you don't hear about any of this stuff anywhere else and that's what's really cool about this podcast.  Everything you've got archived, everything you've learned, you just never read about it back then, you know?

Adam:  It was available to read about, but not in the normal sources that people read about the Astrocade.  Which would have been Electronic Games and some of the other computing magazines at the time.  But they didn't talk about, I mean, it was mentioned briefly... but only as a product that was supposed to come out.  But, in a way, ZGrass did come out.  The product, the language, ZGRASS, was available.  There was a hardware system, a computer (which could cost upwards of $10,000) that used some of the custom chips that were available in the Astrocade.  It was called the UV-1.  It was-- I'll get more into that when I cover the Zgrass system in some future episode, which is why we're talking about it here.  I would like to discover more about it.  I wanna learn.  I want-- I don't think I can use it, because it has not been archived.  But, the documentation is available on BallyAlley.  I have that.  Maybe I'll go through that a little bit.  It was... something to learn about and share...

Chris:  Yeah.  Really cool.

Adam:  It's all about sharing, man.  And caring.  Okay.  The Bally Arcade and Astrocade history.  History of the month is something that we are going to have.  It's going to start with the "Arcadians" #1, which was the first available newsletter.  The "Arcadians" was a newsletter that published for just four issues.  And it was published-- and it was only two pages.  The first one, I think, was only front and back.  Then, I think, maybe the next one was four pages, but that was only two pages front and back.  It was really just a round-robin letter.  It predates the "Arcadian."  It was only available to a few people.  These have been archived.  You can read them online.  I'm gonna start there.  As soon as BASIC was released, it took a few months after the Astrocade came out (excuse me, before the Bally Arcade came out).  Once that system came out with Bally BASIC (which required a separate BASIC interface so that you could record to tape), then Bob Fabris, the editor, said, "We've got something we can explore together.  Let's do this.  Let's pool our resources and come up with a way to share information.  That was what they were all about.  They did this very early on.  That's something that interests me greatly about the system, and I want to be able to share that and compare it with knowledge of other systems that were out at the time.

Chris:  That's really cool.  I mean, it's one of the earliest systems of any kind, that I know of, that actually did have a community.  You know, that were really trying to goad each other into doing new things and write programs and stuff like that.  I mean, I can't imagine there was an Altair community.  I'm trying to...

Adam: There was an Altair community.

Chris:  Oh.  Well, but they were all very rich.  And they had a lot of time on their hands!

Adam:  ...those switches, right?

Chris:  I hope that you're gonna to do a "What's New on Bally Alley" I know I keep going on about this, but that is just an amazing website to me.  You do a lot of updates to it, so when you do add new things to the BallyAlley website.  And, who knows, maybe this will give you a reason to add more things to the website.

Adam:  It could.  The website isn't updated very frequently.  I have great intentions, everyone.  So, if you've been wanting to see updates, give me some motivation to do some.  I don't mean send me money.  We, as the two of us (and other people on the Yahoo group), we do like to BS about the system.  But, there's so much information in my archives, and there are only a few people who share it with me.  Basically, two other people.  We're thinking about putting it up on, but some of it is kind of-- I think it should, might remain hidden from viewers, even though it might be archived there.  Because, it's personal letters that, I think, probably shouldn't be shared.  Because, there's personal information there.  I mean, when I got the collection, there was actually checks still that were un-cashed in it that were written in the 70s.

Chris:  Wow!

Adam:  Those kind of things I did not scan.  Because I was like… what? [sounds of exasperation and/or confusion], it was very strange to me.  They are un-canceled, unused checks out there in some boxes that were people subscribing to the newsletter.  I'm not sure why he didn't cash the checks, but... they're there!

Chris:  So you could have them in the archive, I guess.

Adam:  Right.  But I don't think I wanna-- I don't think that sort of information should be shared.

Chris:  Oh, I agree.  But, you know, I mean back then a dollar, back then, was the equivalent of fifty grand today.  Don't you love it when people say stuff like that?  It's like... well, you're going a little overboard.

Adam:  Right.  [Laughing]  We had to walk up and down the hill both ways...

Chris: Both ways!

Adam: the snow.  Pick up the coal from between the tracks.

Chris:  Any Cosby reference, I'm on!  What I'm hoping... do you think that Paul is going to take part in some way in this first episode?

Adam:  I would like him to.  If we take a long time, then probably.

Chris:  Well, I'm hoping we're going to hear a lot from Paul Thacker.

Adam:  Paul Thacker, he will definitely join us, at least, for the... if he can't make it into this zero episode, he will be in for the first one.  He's a good guy.  He has helped me-- more than helped me!-- he has... he is in control of archiving tapes.  That is his department.  After I wasn't really updating the site too much anymore (I actually had even pulled away from it), in about 2006, Paul Thacker came forward and he introduced himself to me through an email.  He said he would like to help with archiving tapes.  And... he really, really has.  He's the leader in that department.  He has contacted people to make archiving programs possible.  He has followed up with people with large collections.  He has archived them.  Not all of it is available on the website yet, but it is... it has been done.  They're truly archived.  And, what's neat about Paul he has tapes that were available between users.  If you're familiar with growing up with these old systems, you might have had a computer like an Atari 800 or a Commodore 64.  Maybe you had some tapes that you recorded to (or disks).  You would write a "Game Number 1."   And then that was what you'd name the program-- even if the program was a type-in from a "Compute!" magazine or an "Antic" magazine.

Chris:  Oh, you would save it as "Game Number 1"

Adam:  This is how these tapes were.  People would write one program on it... maybe, maybe even give it a clueless name, that meant nothing to either Paul or I.  Paul would record the whole side.  Paul would go through and say, "What's on here?"  Paul would find a program.  Paul would find SIX different versions of that program!  Paul would find programs that had been halfway recorded over.  Paul made sure to archive all of that, separately (and as efficiently as possible), document it.  So, something I want to cover... there are so many topics... I should back up here, and I should say that there are a lot of topics available to anyone who is starting a podcast.  Something that has to be zeroed in on (and that's not supposed to be a pun on the zero episode) is that you have to choose.  You have to narrow.  You have to focus.  I am no good at that.  I am not good at that... I can't do it.

Chris:  How many fingers am I holding up?

Adam:  Chris is holding up a finger, and I'm supposed to see one.  And I'm hoping that is what he was doing-- and not giving me the finger.

Chris: [Laughing]

Adam:  So, I would like to cover the ancestry of the Bally Arcade.  Something that came up and about 2001, perhaps 2002, is someone named Tony Miller, who was responsible for working on the Bally Arcade when it was created, mentioned that the Bally Arcade's chipset is actually a direct descendent of "Space Invaders" arcade game's... the CPU for "Gun Fight".  Or something to that affect.  I didn't understand it then, I might be able to understand it better if I find those exact posts (which are definitely archived).  Now, "Gun Fight" used the Intel 8080 CPU, which is why the Astrocade uses the Z80.  Because it's compatible... sort of.  The Z80 can run 8080 but not the other way around.  As you can see, my knowledge of all of this is completely limited.  What I just told you, is pretty much what I know.  There's obviously a story there.  If I could find people to interview, if I can dig into this, there is a GOOD story there.  And I would like to discover it and present it.

Chris:  Yeah, 'cause that would mean Taito took some technical influence from Midway.  Because it was Midway that added a CPU, at all, to "Gun Fight," right?  So... that's pretty interesting.

Adam:  We'll find out, Chris.

Chris:  Yeah.  So, I've already talked about writing new games as the next logical step once one has a lot of information about any game system, or any computer (or anything like that).  So, are we going to encourage activity in the homebrew Astrocade scene?  Because, there is a latent one there.  You should definitely cover the two released games that we've already talked about: WAR and CRAZY CLIMBER.  Those were pretty big deals.  The first new Astrocade game since... what?... 1985-ish?  I mean, on cartridge...

Adam:  It depends on how you look at it.  There were actually some people in the community, who were just sending cartridges back and forth to each other, who were sharing code in the 80s.  They're not considered released cartridges.  Something that is available to the public… yes.

Chris:  In terms of talking about homebrew programming, you can also talk about people who just play around with this system, or even interview them.  What do you find interesting about the…

Adam:  Yeah.  I would like to do interviews with people who actually have a lot of experience with the system and maybe grew up with it, which I did not do.  I didn't learn about it until... the 90s.  About homebrew programming: I believe, and I would love to make you guys believe, that homebrew programming did not start in the 90s.  I would like to let you know that homebrew programming has been around since 1975 (in my eyes) and earlier.  The very, very first PCs, and by that I mean "Personal Computers," not "IBM Personal Computers," (alright?)... these systems were programmed in people's living rooms, in people's kitchens.  If that is not homebrew programming, I don't know what is.

Chris:  Right.

Adam:  These people were learning for the sake of learning.  They were playing for the sake of the experience of touching the hardware, learning the software-- they weren't doing this for work, they were doing this for pleasure.  This is the same exact reason people are homebrewing games today.  They were doing this back then.  An insight that you get to see very clearly is in the in the "Arcadian" newsletters, and in the "Cursor" newsletters as well, is people want to teach other people.  They are about sharing.  They are about, "Hey I wrote this.  This is great.  You guys should type it in and try it out... and if you find out anything about it, let me know what you think.  If you can add something to it… if you can cut off six bytes and add a sound effect, please do that, because there's no sound."  These people wanted to help each other, and through that it is available in archives, and we can look at this and learn today.  I would like to have that happen, so that people of today, people who have the knowledge, have modern computers that can cross-compile and create new games-- that would be neat... to me.

Chris:  Yeah.

Adam:  It has been neat, went two have been released already.  But, even if new games don't get created, what about MESS?  Let's make that better.

Chris:  Before we go any further, I think you should "share" your email address so that you get feedback.

Adam:  My name is Adam, and you can reach me at

Chris:  You can private message me on AtariAge.  I'm chris++.

Adam:  Now we expect to get loads of email.  We are gonna be clogged.  We're going to have to have the first episode be nothing but reader feedback.

Chris:  I'm telling ya, we really got a good thing going, so you better hang on to yourself.

Adam:  [Laughing]

Chris:  That's a Bowie quote.  Well, before we wrap this up, let's cover the obvious thing.  How did you get so involved in the Bally Arcade/Astrocade?

Adam:  When I first began collecting some of these older consoles and home computers... I never stopped playing them, but when they started becoming available for a quarter, I said, "You know, why don't I just buy each one of them."  I had a very large collection for awhile, until I finally gave some of it to Chris... got rid of most of it, and... I am glad I did, because now I play the games I own.  What I don't play, I get to eventually.  In about 1994... '93... I read about this system in one of the books I had that was from the early 80s that covered the Zgrass, actually.  It was the system, I was like, "I want to get a Zgrass, that'd be neat."  I don't have one.  I did find out that it was related to the Bally Arcade.  From there... I wanted one.  I found my first one for a quarter.  I picked it up at a flea market.

Chris:  Oh.

Adam:  It came with a few games.  In fact, I saw the games first, and I was like, "How much you want for these?"  Each game was a quarter.  I think there was four or five of 'em.  Then I saw the system, but I didn't have that much money with me.  I had like a dollar left or something (I'd already bought some other things).  I was talking to a friend that I'd gone with, and he said, "Why don't you go back there and offer him your buck for it?"  I went back, and I said, "How much do you want for the game (the system)?"  And he goes, "A quarter."

Chris:  Wow.

Adam:  So, I still had change to go by another: 2600, an Intellivision... no... [laughing]  But, I didn't find anything else that day.

Chris:  Those were the days before you people let eBay ruin that part of the hobby.

Adam:  So, I did know that there was an "Arcadian" newsletter.  But, I was a member of an Atari 8-bit user group here in town.  It so happened, I was bringing it up... talking with someone there, and they said, "Oh, I've heard of that!"  I'm like, "Oh, you've heard of the Bally?"  They said, "Oh, sure.  You should talk to Mr. Houser" (who was the president of the Atari club).  Then he said, "I think he wrote some games for it."  I said, "Hmm.  That sounds interesting."  So, I approached him.  By 1994, there were very few users left in the Atari 8-bit group.  Who was left, we all knew each other very well (or, as well as we could-- even though some of us only knew each other from meetings).  We started talking.  He told me that he'd been involved with the "Arcadian."  He had published tapes.  He had something called "The Catalog" [THE SOURCEBOOK], which I now know was the way most people order tapes (but, back then I didn't).  He kept track of all this, and he still had all of his things.  He invited me over one Sunday afternoon and he showed me what he owned, which was... pretty-much everything for the Astrocade that was released.  We went through it one Sunday afternoon, and his son (who was in his early 20s) shared his memories of the machine.  I fell in love: I thought, "Wow, this system is great!"  While I was there Mr. Houser, his name was Richard Houser, he said, "Hey, you know what... we should call up Bob."  I said, "Bob, who?"  He said, "He was the person who used to publish the "Arcadian."  I said, "... Really?"  He's like, "Yeah, let's call him."  So, he called up Bob.  They chatted a bit (for a while) and he told him who I was-- I didn't talk to Bob.  But, he was available back then.  I thought that was great, so I wrote Bob a letter.  I said, "Would it be okay if I get some of your information..."  Later on, in the late-90s, he gave me permission to do that.  At the time, I just said, "Hey.  Here I am."  What's really neat, is I started sending him ORPHANED COMPUTERS & GAME SYSTEMS (which was a newsletter I did in the early-90s.  After three issues, Chris, here, joined me on board).  I sent them to him.  When I bought the Bally collection from him, those issues that I'd sent to him brought back to me.  Which, was, like, this huge circle... because it came through several people, in order to come back.  I found that really neat.

Chris:  Yeah.

Adam:  Eventually, with Chris, we discovered the system together.  We played around with it.  What was it...?  About 2001, I started  It doesn't look great now, and it looked worse then.  Now, here I am... having a podcast.  How about you, Chris?

Chris:  I never stopped playing all the way through either.  You know?

Adam:  Why should've we?

Chris:  Well, yeah.  I kept playing the old games through the period when they started to be called "classic" and "retro."  This happened at some point in the mid-90s.

Adam:  During the HUGE crash during in the 80s (that none of us saw).

Chris:  Yeah... that none of us knew about, except for the great prices (which I attributed to over-stock).

Adam:  I didn't even think about it.

Chris:  Well, they weren't all cheaper.  Even into '83/'84, I remember spending thirty-odd dollars on PITFALL II: LOST CAVERNS for the 2600.

Adam:  Yeah, right.  I got that for my birthday, because it was $30... and I didn't have $30, I was a kid.

Chris:  Right.  'Cause... that was about two-million dollars in today's money.

Adam:  Also, for us, I think, we went onto computers, like many people our age at the time.  So, we sort of distanced ourselves.  The prices for computer stock stayed about the same, as they had for Atari cartridges, and things like that.

Chris:  That's a good point.  Yeah.  In coming across "classic," after I hadn't really stopped playing my favorites (and discovering new favorites, thanks to the advent of thrift shops and video games at Goodwill, and stuff), I'd read that and say, "Oh, they're classic now.  Oh, all right.  If you say so."  I thought that was really funny.  So, by the late 90s, I thought I was the only person on earth (not literally, but pretty close) who is still playing these "old" videogames.  All I had when we started hanging out again, Adam, was an Atari 2600 and a Commodore 64.  That was all I wanted.  I didn't want to know about anything else, I didn't want to know about this new CD-ROM, with the "multimedia."

Adam:  So, let's... this time period would have been...?

Chris:  This is 1997.  By this point, I had been writing my own articles and essays for my own amusement (saving them as sequential files on 1541 floppies using the Commodore 64).  I wrote a file writer and reader program.  I thought I was the only one doing nerdy stuff like this, but I had fun doing it.  And I was still playing all the old games, picking 'em up for a buck or less, while making my rounds at the thrift shops and at Goodwills and everything like that.  I was in a subsidiary of Goodwill that was attached to the largest Goodwill store in Albuquerque.  I ran into a buddy of mine, from ten years previous.  He and I have been freshman in high school, and then I went to another high school and lost touch with all of my friends.  This guy's name, if you can believe this goofy name, was Adam Trionfo.  The store had an even goofier name: the U-Fix-It Corral, but then it changed into Clearance Corner.  Is that right?

Adam:  Correct.  Yes.

Chris:  Adam was working there.  So, I'm going through a box of... something... from the 80s.  He came over, "Are you Chris?"  I said, "Yeah.  Adam?"  He and I, you know, sort of shook hands.  I said, "Well, that's cool, you're working at Goodwill."  "Yup."  Then I left, and I never saw him again...

Adam:  [Laughing] Untill today.

Chris:  Until today.  That's why it really sounds improvised here.  He gave me a newsletter he had written about... old videogames (and they weren't even all that old yet, at the time).  He started ORPHANED COMPUTERS & GAME SYSTEMS (on paper, kids!) in 1994.  I asked him, "So, you write about video games too?"  He said, "Yeah."  We started hanging out playing games... a lot.  I didn't know anyone else at the time who liked to play Atari 2600 and Commodore 64 games.  He eventually nudged me to the Internet (or, dragged me... kicking and screaming).  When I encouraged him to start up his newsletter again, he said he would if I'd collaborate.  We did that for couple of years.  Sent out a lot of paper issues.  Had a ball writing it.  Going to World of Atari 98 (and then CGE 2003).  Using interviews that we had conducted at those to feed the material for the newsletter.  In 1999, it became a website.  We've actually been pretty good about adding recent articles...

Adam:  Recently.  Yeah.

Chris:  ... which is good for us.  I don't know what any of this has to do with what you asked me.  In 1982, we took a trip back East to Buffalo to visit family.  My mom's sister's best friend had a son named Robert, who was a couple of years older than me (I was ten, he was probably twelve or thirteen).  He was the kid who first showed me Adventure.

Adam:  Never heard of it.

Chris:  Summertime of '82 [mumbling/talked-over??] I got my mind blown by it.  This same guy, Robert, took me into his basement to show me his Atari computer (I believe).  He said not to touch it, because he had a program in memory.  He was typing in a program and he had a magazine open.  That's all I remember.  I wish I had focused on the model number or which magazine it was.  It looked like all of this gobbledygook on the screen.  I was absolutely captivated because-- who didn't want to make his own videogames?  I'd been playing Atari VCS games since February of '82.  It became an obsession with me, on par with music (believe it or not).  He said not to touch it because he hadn't saved it yet.  I said, "How do ya save it?"  You know what I mean?  I didn't ask him any smart-ass questions: "Okay, ya gonna take a picture of the screen?"

Adam:  [Laughing]

Chris:  He said, "I save them on these."  He showed me just a normal blank cassette, like you would listen to music on.  That just entranced me: all of these innocent music cassettes hiding videogames on them.  

Adam:  [Laughing]

Chris:  I learned how to program in BASIC that summer from a book checked out from the library.  I mean, I just really got interested in talking to this new thing.  This home computer: the microcomputer (as it was called quite often).  The "micro" to separate them from "mainframes," because, you know, a lot of our friends had mainframes in their bedrooms.

Adam:  Right.

Chris.  Then he brought me over and showed me one more thing before we had to go.  This was the Bally Professional Arcade.  I thought it was one of the most amazing things I've ever seen.  We played THE INCREDIBLE WIZARD.  He let me play for a little while.  I said, "This is just like WIZARD OF WOR!"  He said, "Yeah, it is."  I can't remember if he had an explanation, or had read an explanation, of why the name was changed.  That was my only experience with the Astrocade.  I loved the controller.  To this day, it is still one of my favorite controllers.  I love the trigger thing, and I love the combination of a joystick and a paddle in one knob on top of it.  I didn't see another Astrocade until I started hanging out with you again in '97.  It figures that you were able to collect all of that amazing stuff because you worked at Goodwill.

Adam:  I didn't use that to my advantage.

Chris: [sarcastically] I'm sure you didn't!

Adam:  I wasn't allowed to do that.

Chris:  Yeah, well, I'm sure you didn't steal it...

Adam:  No.

Chris:  But I mean, come on!, you probably made note of what came in.

Adam:  There was actually a rule that I had to follow.  When anything came in, it had to sit on the shelves for 24 hours before it could be purchased by an employee.  That didn't mean we had to show everyone where it was, but it had to be out.  And, that was true: it was out.  That didn't mean we said...  (because there were people that came in every single day, just like I used to like to go around too).  It would be on the shelf, but that didn't mean it would be right on the front shelf, saying, "Buy me please, Atari game collector."  It was in the store somewhere!

Chris:  You put it in the back, near the electric pencil sharpener!

Adam:  No, I didn't hide it either.  I didn't want to get in trouble.

Chris:  Nah.  I know.  Adam had an original Odyssey with all of the layover-- the "layovers?"  With all the airplane stops.  No, with all the overlays.

Adam:  [Laughing]

Chris:  Which, is pretty amazing!  You had an Odyssey, with original 1972 Magnavox console, with everything else: an Intellivision, he had an Odyssey 2 (with boxed QUEST FOR THE RINGS)... and...

Adam:  I had 43 different systems.

Chris:  Holy cow!

Adam:  I am so glad that I don't have that anymore!

Chris:  That is a lot for an apartment.

Adam:  So, now I have a few left.

Chris:  Yes, folks, he does have an Astrocade.

Adam:  I do.

Chris:  He does have all of the original cartridge games for it.  I think you got all of them?

Adam:  I had them, but now I have a multicart.  I got rid of most of them.  I feel... I kept some of my favorites.  I kept my prototypes.

Chris:  Which is cool.  Obviously, you have WAR and CRAZY CLIMBER.

Adam:  Right.


Adam:  I think, I have number 2's, because the programmer got number 1's.

Chris:  That's pretty cool.  

Adam:  Yeah.  But, honestly, I don't care about the numbers on them.  They were hand numbered, because collector seem to like that.  Personally, since I did the numbering, I found it annoying.

Chris:  Well, there were fifty sold?

Adam:  There were fifty each.  Yeah.  There was a run of 20 for WAR, because we didn't have any cartridge shells.  We got more, and we did the second run.  The run of CRAZY CLIMBER was always 50.  It was released all at once.

Chris:  You have number two, and [sarcastically], that's a collectors item..

Adam:  Right!

Chris: ...if anyone knew what it was.

Adam:  I should have got number 0!  Think of this, this episode is a collector's item already!

Chris:  You taught me a great deal about the Astrocade and how it worked.  You've told me some things that I just find...  so cool.  Like, you had to use the screen for code, because part of your available RAM was the Screen RAM, right?  (And still is.)

Adam:  Under BASIC, that's correct.

Chris:  That's how I became even more interested in the Bally Arcade/Astrocade.

Adam:  We are about finished wrapping things up here.  Just for the last few things to say.  We are going to have an episode every two weeks (or so).  So, that would be bimonthly.  I hope you guys... if you have any ideas that you want to come up with, will send in some feedback.  If we get no feedback by the first one, that's okay... because we expect... a couple of people... to listen to this.  

Chris:  Thanks for listening, and thanks for inviting me along, Adam.

Adam:  Good to have ya!
