Or design a little converter board with a PIC. Better yet, leave the
Atari MB inside (if possible) and use THAT as the keyboard converter.
Write a small program on the Atari that spits out converted keycodes from
the Atari's serial port to the PS/2 port on the PC. Now THAT would be
cool (if not a bit dysfunctional unfortunately).
