I was thinking of doing a pin-compatible replacement for the Amiga keyboard controller, which I guess is based off the 6502 (with some mask ROM). This gives me hope that it’s possible, because there’s no way reading a keyboard matrix is harder than being a SID.
As far as I can tell, the controller chip in my A3000 keyboard is dead - the machine doesn’t communicate with it, but works fine with many other keyboards. I’m sure it actually isn’t “fully” dead (no scope to test with), but the 40-pin DIP layout is really appealing for hardware hacking.

Interesting, what on earth do you need that for?

Cool!
