Atari 2600/5200 Technical Info, Etc.

My Resources

This is information that I have either generated or compiled from other sources.

• Graphic: Atari 5200 Memory Map
• UPDATE: I've used the ATMEL AT29C256 flash to build a flash cartridge for the 5200. I also have a design for a parallel port programmer for this flash, as well as some source code that runs under FreeBSD and should be fairly portable.
• UPDATE: I have some headers and configuration files that allow you to use the cc65 C compiler to develop software for the 5200. I also have some stupid demo programs and a simple threading kernel written in C and assembly. I'll post this stuff when I get some time.
