Do you mean the CPU board, the power driver board, or both? The
switch circuitry is on the CPU board; everything else is on the power
driver board.
On which do you intend to plug in the parallel port?
My guess is you want to dump the CPU board completely and use a PC for
that. You could rig something from a PC parallel port to the power
board OK, but then what about the switches? Also I'm not sure a
single parallel port has enough I/O lines to do everything.
