Coleco Graphics Processor
(also known as "Project Name By Line")
Coleco Electronics

This is the actual program that was used to write ColecoVision and ADAM games at Coleco and to connect to VAX Mainframes! There are many versions floating around, but the prized version to have is the properly patched cartridge version. The cartridge version, besides allowing you to write and manipulate Coleco games, will also allow for the capture of screen displays when you press the "Cartridge Reset" on the ADAM. It, however, does not capture any sprites on the screen at the time. You can then manipulate the sprites, background graphics, etc. You can save captures to tape/disk as well as modify these screens. It allows you to connect to the VAX mainframe (for those of us who have one at home), to compile or for libraries of routines. The cartridge is a special 64k cartridge (RAM for screen captures). There are at least 3 versions of this. An EOS (Standard ADAM OS) disk or DDP, CP/M disk or DDP, and the cartridge. All are basically the exact same program with the exception of how the program loads. The non-cartridge versions require a 64k or greater memory expander for the ADAM, while the cartridge version has this feature built in.
