The Commodore 64 CP/M cartridge has a Z80 processor running at 1 MHz. The schematic diagram of the cartridge was reverse-engineered by Ruud Baltissen. There is also some documentation on this cartridge in early prints of the Commodore 64 Programmer's Reference Guide. In later prints, the pages that originally described the CP/M cartridge were left blank.
