Cartridges

"Jon Guidry's cartridge project will also allow for all of the eprom-based cartridges listed below to be used on Jon's new boards. In addition, All of the bona fide cartridges (not program conversions like ARCHIVER, etc.) listed ARE NOW available as HSGPL dumps.

Please feel free to email me (Bob Carmany) to ask about specific cartridge availability." (added 1/28/2009)

All of the cartridge titles require one of the ROMOX-type cartridges or any cartridge board that will mount a 28-pin eprom. No more cartridge boards are available from this source but there is a German-produced board by Heiner Martin that might still be available.
