The Final Chess Card (from the makers of The Final Cartridge I-III) does use
a 65C02 (overclocked to 5 MHz), but that one runs in parallel to the 6510. A
common RAM area is used for communication between the chess CPU and the 6510.
The BTX Modul II works in a similar way, it uses a 6803 CPU/MCU that runs the
BTX stuff and communication is done via a special Motorola dual port RAM.
