I was thinking... isn't the PS/2 keyboard protocol simply a
low-bitrate serial protocol at TTL levels?  Could the 6510 then not
act as the microcontroller?

That is, why not connect the user port to the PS/2 port and run a
program on the C64 to send the keypresses to the PC?

Of course, this runs dangerously into the direction of a "why use an
emulator if you have the real thing" kind of debate... :-)
