   I think the
idea is to use a defunct C64 and use it as a keyboard for t=  he emulator.

 That's why you use an el-cheapo keyboard and pull the board from it, and=20
 hook up your own matrix... 
The problem with doing that is that the C64's keys are already wired in a 
matrix, and you can bet it won't be the same as the one for the keyboard 
you raid the controller from.

And, assuming you want the letters to appear in the conventional 
locations, etc, you then either have to do a lot of cut-n-jumper on the 
C64's keyboard PCB, or reprogram the controller chip. The latter would 
seem to be more work than programming a microcontroller from scratch 
(particularly since the code is availalbe -- right?), even assuming it's 
possible (e.g. the controller might be mask programmed or OTP).
