ISA:

  • Support 6502/10 invalid instructions
  • Support 65C02 instructions

Pre-requisites:

  • Parser v2? #2 to make v80 even more data-driven and minimise the amount of Z80 code that has to be directly ported

Target systems / platforms?

  • CPM65 would allow an easy landing-site for porting from Z80 CP/M
  • Commodore 64. Ironically has limited RAM due to complex RAM layout!
  • Apple II. Large user base. Varied hardware configs? (AppleDOS / ProDOS?)
    Start with a Z80 CP/M port to the Apple SoftCard?
  • Modern 6502 systems:
    • neo6502
    • CommanderX16
