What's New


November 15, 2018

  1. Added an overview of Electronic Visualization Center by Dan Sandin and Phil Morton. Also included in this video is a general background for Bally Arcade/Astrocade video art. Only the last few minutes of this video is dedicated to the Electronic Visualization Center BASIC overview. The majority of this video contains a general history of video art and how it relates to the Bally Arcade.

    1. Electronic Visualization Center by Dan Sandin and Phil Morton (Video Overview)

November 12, 2018

  1. Added Scroll One, Scroll Two and Scroll Three by Larry Cuba.

    These video art programs were printed in the Bally BASIC and "AstroBASIC" manuals. They each fill the screen, line by line, with patterns of different sizes of boxes.

    1. Scroll One, Scroll Two and Scroll Three by Larry Cuba (Video Overview)

  1. Added Random Box by Scott Walpole.

    This video art program appeared in the December 1979 issue of the Arcadian newsletter along with three other short programs by Scott: a game called Number Match and two music programs, Hello, Dolly and Popeye the Sailor. The Arcadian has no instructions or comments for Random Box. The program simply draws random-sized boxes on the screen and the colors periodically change.

    1. Random Box (Video Overview)

November 7, 2018

  1. Added video overview of Perspective Box by Rickey Spiece. This program was published in the 1978 version of the Bally BASIC manual on page 115.

    Perspective Box draws a "box" which is meant to have a pseudo 3D perspective in a corner of the screen. The program changes the color of the box and then "shrinks" it. The program is simple enough that it wasn't included in the manual for the re-release of Bally BASIC, but it probably helped early purchasers and users of the Bally Arcade go on to create video art.

    1. Perspective Box Overview
  2. Added TERSE programming language Z80 assembly language source code called "Add-Whatever Graphics and I/O Extensions" by Jay Fenton written in February/March 1979.

    1. "Add-Whatever Graphics and I/O Extensions" by Jay Fenton
  3. Added a 33-page manual called VGER from June 18, 1981. This document is from the collection of Jamie Fenton.

    I'm not sure what VGER is an aberration for, but it seems to describe how to use the TERSE programming language with macros that are in (perhaps?) a header file of some sort.

    1. "VGER" Document
  4. Added TERSE Debugger Package document. This is a two-page list of the commands required to use the TERSE interactive debugger.

    1. TERSE Debugger Package Document
  5. Added a two-page "Video Game System Glossary" from the collection of Jamie Fenton.

    I think that this document has to do with the TERSE programming language. Here is the first paragraph from the Proposed Video Game System vocabulary document:

    "This is a description of the VGS vocabularies. The words are presented in ASCII order. The first line of each entry shows a symbolic description of the action of the word: symbols indicating which parameters are to be placed on the stack before executing the word, 3 dashes (---), indicating execution, then any parameters left on the stack by the word. In this notation, the top of the stack is to the right. The place of the word in the input string is not completely obvious, is shown explicitly. If no dashes are shown the word does not affect the stack."

    1. Video Game System Glossary
  6. Added a 16-page document called "Z-80 Disk Block Organization" from the collection of Jamie Fenton. This document seems to be the op code formats for TERSE assembly.

    1. Z-80 Disk Block Organization

November 6, 2018

  1. Added information about the possible author of the 300-Baud Star Trek game.

    1. Star Trek by Unknown (300-Baud Program Download Area)
  2. Added a three-page book excerpt from the 1978 book An Introduction to Personal and Business Computing by Rodnay Zaks. This book excerpt cover the Bally Arcade and the Umtech VideoBrain.

    1. An Introduction to Personal and Business Computing by Rodnay Zaks
  3. Added link to Astrocade video art overview.

  4. Added "Discussion with Rickey Spiece of Dave Nutting Associates." This is a compilation, by Richard Degler, of eleven postings to the Bally Alley Discussion group.

    1. Discussion with Rickey Spiece of Dave Nutting Associates
  5. Added "Programmers of the Bally Arcade/Astrocade Built-in Programs" compiled by Adam Trionfo on August 17, 2016. This is an attempt to credit those people who programmed the four programs built into the Bally Arcade/Astrocade.

    1. Programmers of the Bally Arcade/Astrocade Built-in Programs
  6. Added "TERSE - Edit Verbs (Revision #4)" handwritten Notes from 198x. These are from the collection of Jamie Fenton (BitSavers.org). This is four pages of short notes on how to use the editor to edit TERSE files, including a set of Edit Control Characters.

    1. TERSE - Edit Verbs (Revision #4).

November 1, 2018

  1. Added 1976's Standardized Test Procedure for Midway's Processor Boards (MM 1701-1) by Midway Mfg. Co. (A Bally Company).

    The tremendous success of Midway's Gunfight and Sea Wolf games in the coin-operated amusement industry has created a new kind of need. This book has been specifically tailored to meet the requirements of troubleshooting Midway's Processor Boards, (henceforth - referred to as Mother Boards). It does not in any way try to explain how the board works. Throughout the book the major emphasis has been on "How to Fix the Board" and no attempt has been made to describe "How it Works".

  1. Uploaded 46 patents cited by the Bally Arcade and Astrocade patents to Archive.org.

    I have uploaded to Archive.org a collection of the 46 patents cited by both of the Bally Arcade/Astrocade patents 4,301,503 and 4,296,930. It's pretty neat reading/browsing the patents referenced in the Astrocade patents. Some of the referenced patents go back as far as 1958. Also, some of the patents are for systems from Atari, Magnavox's original 1972 Odyssey or even very obscure computers like the VideoBrain.

  1. Added a link to an Astrocade Video.

    1. Added a link to a console review of the Bally Arcade/Astrocade by Jason Slaughter. This video was published to YouTube on February 1, 2012.
    1. Bally Aracade/Astrocade Console Review

October 28, 2018

  1. Added a schematic for a Bally Arcade/Astrocade 16K DRAM (Dynamic RAM) add-on by John Perkins.

    This is a 16K DRAM add on. The Blue RAM was a 4-16K or 32K SRAM (Static RAM). There are a lot of differences between the 2 types of RAM. DRAM is what is in the Bally. This scheme is a way to add 16K of memory to the Bally / Astrocade.

    1. 16K DRAM Blue Ram Add-On by John Perkins.
  2. Added links to two Astrocade Videos.

    1. "Remembering the Future - Live!" (Live Video Art Performance) by Jason Slaughter.
    2. "Remembering the Future (Revised)" (Video used in Live Art Performance) by Jason Slaughter.
    1. Bally Aracade/Astrocade Video Area
  3. Added Gun Fight Computer Service Manual: For the Midway 8080 Microprocessor Game Series, A Comprehensive Analysis of the Gun Fight Game Computer by Midway Manufacturing Co, published in 1976 in William Arkush Video Game Data Books, Vol. 4.

    This Gun Fight manual is referenced in the Bally Arcade/Astrocade patent (U.S. Patent 4,296,930, "TV Game Apparatus"). Tony Miller, a hardware engineer who helped create the Bally Professional Arcade, once said that the custom chips in the Astrocade were created from the hardware in such games as Gun Fight. Gun Fight is normally considered the first arcade video game that used a microprocessor (it uses the 8080 CPU).

    1. Gun Fight Computer Service Manual: For the Midway 8080 Microprocessor Game Series by Midway Manufacturing Co.

October 27, 2018

  1. Added Bally Artillery by John W. Rhodes. This program is from Creative Computing, August 1982, Pages 191-192.

    John Rhodes writes: "I particularly liked the artillery game that Compucolor called 'Shoot.' This game generates a random terrain display and wind factor and positions two artillery emplacements on the screen so that two opponents can take turns trying to obliterate each other. Eventually I resolved that I either had to buy a Compucolor or program this game on my Bally. I chose the latter."

    Lance Squire typed in Bally Artillery in June of 2018. It runs, but doesn't work exactly as it should. It probably has a couple of typos in it, but it's still worth looking at and playing.

    1. Bally Artillery
  2. Added a Blue Ram Notebook by John Perkins. This is a 24-page handwritten notebook describing the "Blue Box" to Bob Fabris. This is certainly the earliest, most in-depth description of the Blue Ram expansion unit. There is no date, but I suspect that this notebook was written in about 1979 or 1980.

    This is a transcription of the first page of the notebook:

    "This notebook is intended to provide you with a glimpse of the potential of our 'Blue Ram' accessory. The full potential is too vast to be adequately treated in a book 10 times the size. This is because the 'Blue Box' provides the Bally Arcade with many of the features of a normal personal computer about which volumes have already been written. What I hope to provide here is a sketch of what the 'Blue Box' can do as well as some sample "experimental" applications."

The video art area now has 11 new videos in it. Other Astrocade-related videos have also been added to the various video areas. The update is in-progress and will be done in a few weeks.

    1. Bally Aracade/Astrocade Video Area

September 28, 2018

  1. Added Mod 2 by Dan Sandin from Computer Graphics and Art, 1980-1981 Yearbook 5.

    MOD 2, is a Bally BASIC video art program, that appeared in an article called Pix-Art by Frank Dietrich and Zsuzsanna Molnar. This article 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.

    Dan Sandin's program needs about fifteen minutes to finish a single one of these MOD images, consisting of circles which seem to be mapped onto globes. This compact 10-line program uses only two nested loops to create the basic structure which scans the whole screen.

    1. Mod 2 by Dan Sandin

  1. Added additional details, descriptions and an updated rough version of a map of the game's layout for John Collin's Treasures of Cathy game. This version of the map is labeled 1.2.

    1. AstroBASIC Treasures of Cathy Program/Map Download

September 20, 2018

  1. Added David Turner's in-progress Z80 disassembly of Midways arcade game, Gorf.

    In 2018, Jamie Fenton (formally Jay Fenton), the programmer of Gorf, donated documentation and hardware items to the Computer History Museum in Mountain View, CA. This included Gorf source code and other documentation related to the game. Gorf was not written in machine language, it was written in a Forth-like language called TERSE (Terse Efficient Recursive Stack Engine) that was developed at DNA.

    After the TERSE source code for Gorf became available, David Turner, an avid fan of the game, began to use the game's source code to disassemble Gorf and comment it. Details of his work, as well as his in-progress Z80 disassembly for Gorf is in this archive.

    1. Gorf Z80 Disassembly
  2. Added an updated map of the game's layout for John Collin's Treasures of Cathy game.

    1. AstroBASIC Treasures of Cathy Program Download

September 12, 2018

  1. Added additional details, description and a rough version of a map of the game's layout for John Collin's Treasures of Cathy game.

    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.

September 6, 2018

  1. Added a January 1, 1983 letter to Bally Arcade/Astrocade vendors By Bob Fabris.

    On December 30, 1982, Astrocade, Inc. declared Chapter 11 bankruptcy. Bob Fabris wrote this letter, hopefully of opportunity, to many of the venders who wrote software and created hardware for the Astrocade. Bob hoped to be able to carry the thousands of Astrocade users through the coming drought brought on by the declaration of bankruptcy. This one-page letter describes Bobs ideas on how to do this for Astrocade owners and distributors.

    1. Letter to Bally Arcade/Astrocade Vendors

August 26, 2018

  1. Added brief descriptions to the ten pictures of Michael Matte's hi-res Bally Arcade/Astrocade. Michael has also written a "tour" that provides detailed information on MCM Design's low/hi-res Astrocade for anyone desiring to take the challenge and build such an Astrocade. The details may help provide ideas for creation of someone's own version of a hi-res Astrocade.

    1. Hi-Res Astrocade by Michael Matte

August 16, 2018

  1. Added ten pictures of Michael Matte's Bally Arcade/Astrocade, which he upgraded from "consumer" mode, low-resolution (160x102), to "commercial" mode, high-resolution (320x204).

    1. Bally Pin Z80 Disassembly

June 11, 2018

  1. Added a preliminary Z80 disassembly (version .01) of Bally Pin (aka Astrocade Pinball). This game was released in 1979 by Bally Mfg. Corp. It was programmed by Bob Ogdon and the audio was created by Scot Norris.

    The idea to hack the tables in Bally Pin led to this disassembly of the game. Only about 2 1/2 hours were spent on this disassembly. It's really just an example of how quickly progress can be made using some of the tools available on BallyAlley.com.

June 1, 2018

  1. Added an "AstroBASIC" version of the Color Organ/Light Show Demo by L&M Software. This is the September 1980 Bally BASIC version that has been saved in "AstroBASIC's" 2000-baud format. This program was designed to work with the L&M interface unit, which probably plugged into hand controller ports 2 and 4. Moving the knobs on those two controllers has the effect of simulating (to a limited extent) the "stereo" input that the stereo hardware interface would have allowed.

    1. Color Organ/Light Show Demo, by L&M Software.

May 29, 2018

  1. Added the Datamax UV-1R, ZGRASS Graphics System: Operator's Manual by Real Time Design, Inc. This version of the manual is from January 4, 1983.

    The Datamax UV-1R Zgrass Graphics System is a highly interactive, dedicated micro-computer color graphics system designed to easily produce visuals in motion. The UV-1R (University Version 1 Rack-mount) hardware is Z80 microprocessor-based. The Zgrass (Z80 GRAphics Symbiosis System) software is both a high-level computer graphics language and a sophisticated operating system. The EPROM (Erasable Programmable Read Only Memory) firmware houses Zgrass and allows for easy software updates. The system's heritage derives from video arcade games, and the high-speed animation "tricks" so easily programmed on this computer are a result of the development of video game technology and custom video chips.

    1. Datamax UV-1R, ZGRASS Graphics System: Operator's Manual, by Real Time Design, Inc.
  2. Added a Viper System Pamphlet by Alternative Engineering.

    The cover of this pamphlet says Video Image Processing Equipment Research. This four-page document has specifications for the Viper System 1, 16K Memory Expansion for the Bally Arcade/Astrocade.

    In episode 7 of the Bally Alley Astrocast Chris and I review the Dog Patch cartridge, the 1980 Astrocade port of the 1978 B&W Dog Patch arcade game. Due to scheduling conflicts, Paul and Michael could not record for this episode, so Chris is co-hosting the show with Adam.

    1. Bally Alley Astrocast, Episode 7 - Dog Patch and O-Jello
  4. Added an archive version of the Bally Alley Astrocast, episode 8 (March 12, 2017) along with its show notes.

    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.

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.

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.

  1. Added How to Modify an Astrocade Cartridge for EPROM/EEPROM Support by Michael Matte.

    Includes a schematic of a modified videocade (Bally Arcade/Astrocade cartridge) to support/test programmed EPROM/EEPROMs. Michael modified a videocade cartridge and wired it as indicated on the attached schematic back in the 1980s. He may originally have been thinking in terms of EPROMs, but eventually wired a 16-pin header for use with an 9K EEPROM. He also inserted a 32K EEPROM because they're really cheap now. No changes were required.

  1. Added SetScreen 2 - An Upgraded Bally Arcade/Astrocade Troubleshooting Utility by Michael Matte.

    SetScreen 2 is an improved version of the original SetScreen, a machine language routine. 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. Details are provided in Troubleshooting the Bally/Astrocade Motherboard Power-Up with SetScreen, A New Tool. SetScreen 2 now has added routines to help a troubleshooter further investigate what is or is not going on with a motherboard graphics-wise and to provide more information to diagnose and isolate a problem area. A read routine is also included for a user who can connect a homemade dual 7-segment display.

    1. Balcheck Supplemental Info
  2. Added Troubleshooting the Bally/Astrocade Motherboard Power-Up with SetScreen, A New Tool by Michael Matte.

    This document is for anyone with experience in troubleshooting the Bally/Astrocade motherboard. It explains one method on how to fix an Astrocade using step-by-step methods. It was written by Michael Matte, the person who designed and built a modified Astrocade that runs with low or high resolution graphics. Specifically, this document addresses the scenario in which a blank TV screen appears when powering on a motherboard and describes a new, very useful tool to help isolate the problem area.

October 12, 2017

  1. Added pictures and screenshot of Michael Matte's high-resolution Astrocade.

    Included is a picture of Michael Matte's Hi-Res Astrocade system. Besides the obvious QWERTY keyboard addition, there is also an external keypad. Although the system has a Viper attached to it, that is only the case: the actual Viper hardware is not inside there, instead, it contains Michael's hi-res upgrade.

    Two screenshots are of the low-res game Gunfight and the low-res menu running on a hi-res system. The third screenshot is a version of the MLM (Machine Language Monitor) cartridge that has been specially modified to work with the Michael's hi-res system.

    1. Michael Matte's Hi-Res Astrocade Area

August 30, 2017

  1. Added a screenshot of Michael Matte's high-resolution Astrocade.

    In August 2017, Michael Matte continued to work on some projects with his Astrocade that he upgraded from the Bally's standard low-resolution (160x102) to High-Resolution (320x204) in the mid-1980s. Near the end of August 2017, he took a screenshot of a hi-res demo that he wrote to test the unit.

    1. Hi-Res Astrocade Screenshot
  2. Added a two-page sheet with the DIP Switch Settings for the UltiMulti Cartridge 3.2 by GaMBITS (Ken Lill).

June 26, 2017

  1. Added a Z80 disassembly of 1983's Ms. Candyman released by L&M Software and programmed by Andy Guevara. This game is a 4K cartridge released for the Bally Arcade. Ms. Candyman is the sequel to Candy Man, which was released on tape.

    1. Ms. Candyman Disassembly

June 19, 2017

  1. Added Crosshatch by Adam Trionfo. This short "AstroBASIC" program draws a crosshatch pattern to the Bally's screen using the '#' marks. The program was written so that a digital camera can be pointed at a TV screen to take pictures (screenshots) and videos. The pattern helps to focus the camera and check for level, as well as to center the TV in the frame.

    1. Crosshatch

June 5, 2017

  1. Added three "AstroBASIC" programs for use with the Spectre Control Handle, often called the ICBM Attack controller. These programs are from the Spectre Handle documentation. The three programs are Animated Box, Get the Box and Keypad Game.

  1. Added 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."

    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."

  1. Added CHRDIS by Mike Skala. This tutorial series, and its accompanying programs, were published across three issues of the Arcadian: CHRDIS I. Arcadian 5, no. 1 (Nov. 5, 1982): 14-15., CHRDIS II. Arcadian 5, no. 2 (Dec. 3, 1982): 37., and CHRDIS III. Arcadian 5, no. 4 (Feb. 18, 1983): 72.

    This three-part CHRDIS article describes how to use the Bally Arcade's built-in Character Display routine from within Bally BASIC. I think that the programs included in the article are "AstroBASIC"-only, but the general principles talked about in the article should apply to Bally BASIC too.

    "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!"

    1. CHRDIS - by Mike Skala

March 9, 2017

  1. Added Palo Alto Tiny BASIC, Version 3 by Li-Chen Wang. This article (which includes the source code and assembly listing) is excerpted from pages 58-88 of the 1977 book PCC's Reference Book of Personal And Home Computing, Edited by Dwight McCabe.

    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.

March 8, 2017

  1. Added High-Res 'Test Rotate' Routine by Michael Matte. This was written in 2017.

    The "Rotate" routine rotates a 4x4 pixel pattern that resides in the Astrocade's user RAM. This routine was written for use on a modified high resolution Astrocade, but it includes instructions on how to modify the routine to work on a low-res unit.

February 24, 2017

  1. Added The Crown of Zeus castle map by Edward Mahoney. This was sent to Bob Fabris on April 20 1983. Edward created a map for Todd Johnson's game, The Crown of Zeus-- which was published in Arcadian 5, no. 1 (Nov. 5, 1982): 7-10. An excerpt from Edward's letter says:

    "The reason I'm writing is to share with you the attached drawings of what I think the castle in The Crown of Zeus (volume 5:1:7) by Todd Johnson looks like. I would like to know if anyone has written this program to produce graphics on the screen of the movement from room-to-room. I think this would be a great program to see with graphic displays. Perhaps, some of those great programmers that write in the Arcadian can publish game graphics for this program."

    1. The Crown of Zeus - Castle Map by Edward Mahoney
  2. Added floor plans for Todd Johnson's The Crown of Zeus. These floor plans were created by Kent Brenden and sent to the Arcadian on July 9, 1983. The Crown of Zeus was originally published in Arcadian 5, no. 1 (Nov. 5, 1982): 7-10. Here is an excerpt from Kent's letter:

    "The graph paper enclosed contains the floor plans [for The Crown of Zeus]. Each level is labeled, each room is numbered with it's exits shown. The set of lines that extends from one room to another indicate a passageway from one room to another. If the set of lines don't go into another room (as with room 13, level 3), this indicates that you can leave the room but once out of that room you can't reenter that room."

    Kent made some changes to the program (which are included). These changes make the game a little easier to play. Included in the letter is a hint for Artillery Duel (probably the BASIC version of the game), which makes it nearly impossible for the other player to hit you. Ken also talks about File Searcher, scrolling, Magic RAM, and the CHRDIS (Chraracter Display) on-board subroutine.

    1. The Crown of Zeus - Floor Plans by Kent Brenden

February 22, 2017

  1. Added BASIC listing of Bob Mueller's 1980 Bally BASIC game, Slot Machine. This was printed in the January 1980 issue of the Arcadian newsletter. This version of Slot Machine has an interesting set of graphics as the "reels" rotate.

    This is the original Arcadian program submission letter, extensive program documentation (which was omitted from the Arcadian's printing of Slot Machine) and the handwritten Bally BASIC listing of the Slot Machine code.

    1. Slot Machine - Original submission letter, program and documentation
  2. Added the original program submission letter, handwritten BASIC listing and documentation for the "AstroBASIC" game called The Crown of Zeus by Todd Johnson. This was printed in Arcadian 5, no. 1 (Nov. 5, 1982): 7-10.

    This game 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.

February 20, 2017

  1. Added BASIC listing of John Collin's 1980 Bally BASIC adventure game, Bally's Alley.

    An adventure game; one player. Game can last for days or weeks; can save at any point for restart; can go in nine directions; find the ten treasures and return to house; can only carry four treasures at one time. Each move subtracts a point. A magic word-sound-color will be helpful.

  1. Added 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. The author methodically noted down four sets of numbers for each ASCII character. This information nicely supplements 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.
