Came across this today - would be ideal for anyone looking to resurrect a dead machine without having to resort to cannibalising the ever decreasing number of working machines out there.

Technically it'll replace the following:
  • 6510 (C64) (8500 is same as 6510)
  • 6510T (1551 floppy drive)
  • 8501 (C16, C116, Plus/4) (7501 is same as 8501)
  • 8502 (C128)
The GitHub for the project is here:

Oh cool I was thinking it should be possible, one less thing to add to my TODO list 🙃
Although I wonder how they handle bus arbitration, IIRC regular 6502 don't have the signals to suspend them… Or do they halt the clock or something?
