However, this might not be an issue for running the firmware on the 6502 core in VICE. The Commodore engineers were accustomed to programming the NMOS/HMOS versions of the 6502 at the time. The 'C102 was probably chosen for the LCD primarily for its power consumption and availability at the time. We won't know until disassembly but it's possible the firmware does not even take advantage of these extra features.
