Universal C64 Cartridge

A C64 cartridge with USB connection for uploading CRT files from a PC and for fast turnaround time when developing assembler programs for the C64 on a PC. The board contains a MC9S08 microcontroller, a 128 kByte SRAM and a CPLD, which can be programmed to emulate many cartridge types. With a different firmware it can be used in standalone mode, without a C64, for other applications as well, like a logic analyzer or a motor controller.
