Here are some of the web sites that have Bally Astrocade related content. I have worked hard to find relevant Astrocade information. It is my hope that the assembly-related can be used to create new Astrocade emulator images, and perhaps even new cartridges.

Sites marked with an '*' are Bally Astrocade only.

Kansas City Standard Ronaldo Goulart, a programmer working on a 300-BAUD digital archiving tool for Bally BASIC, points to this transcription of the original article from Byte, describing the Kansas City Standard. The list of eighteen participants of the symposium includes a known name, "Bill Gates, MITS." There is an interesting thing in it: the "official" length of the lead-in is specified as "a minimum of five seconds of marks".

* Astrocade Group Bally Alley's Astrocade discussion group at Yahoo Groups. Read what other people in the Astrocade community are doing. Back in 2001, the original long-term goal was to create an Astrocade CD, but now has negated that idea.

* Astrocade Wiki Page has created a short Wiki page that is setup for the Bally Astrocade. It includes information about the Bally hardware. Currently it has data in these catagories: Chip Info, Quick Voltage Reference, Schematics, Service Manual, Overheating Chips, and a Capacitor List.

* Bally Astrocade Cap Kit sells a "kit [that]] contains all parts necessary to replace the electrolytic capacitors in the Bally Astrocade."

  Digital Press The great paper newsletter's online presence.

Z80 Homepage A great resource! A general Z80 site that contains docs, FAQs, source code, cross-assemblers, cross-compilers, utilities, etc on the the Z-80, the CPU used in the Bally Astrocade. Sometimes this link might seem dead (don't know why), if it doesn't work now, try again later.

TI (Z-80) Calculators Some excellent tutorials on programming the Z-80 with step by step directions for beginners. Check out the TI-83 Assembly Logs Vol. 1-8 in particular. This is aimed at TI calculator programming-- but you will pick up some great information none-the-less.

TI-83 Asm Help File TI-83 calculator tutorial set up as a Windows Help file. Useful and relevant overviews and code. Very nice.

* MAME Astrocade Emulator The only Bally Astrocade emulator. Not perfect, but getting closer. Support the loading of some tape images into BASIC.

All of the source for this board is available on the page... so check it out. This site was added on February 4, 2010. As of 2016, the link no longer functions, but you can download the contents of the Bally page, here:
