IconAndre Fachat has created a CPU add-in card for Commodore PET machines. "It speeds up your PET to up to 12.5MHz (at least that's the plan for the final stage, but it currently looks good!). The board uses a 65816 CPU that runs at up to 12.5MHz, plus a Xilinx CPLD as logic glue. It includes up to 1MByte fast RAM (run at CPU speed) plus 512k parallel Flash ROM, that can be used as boot ROM". Source code and schematics are provided. Via Commodore News Page.
