MOS CPU Replacer for C64

[Kai Robinson]

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.

MOS CPU Replacer (6510/8501)

Please read the entire description before ordering. Replace rare/expensive/unreliable MOS CPUs 6510 (C64) (8500 is same as 6510) 6510T (1551 floppy drive) 8501 (C16, C116, Plus/4) (7501 is same as 8501) 8502 (C128) The above 'CPUs' are just standard 6502s with some extra logic tacked on inside...

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)

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?

Cool! I have a dead Plus/4 and have been wondering how to revive it.

Out of stock.. doh.
