I wondered about something like this from the perspective of hooking
relays and sensors.  I discovered to my dismay that the UNIXpc doesn't
use a nice flexible parallel i/o chip, but rather a simple latch for
output and a couple of other bits of input to test for data strobe
and printer ready.  If you can be satisfied with just a few bits,
you might be able to write a replacement driver and use it, but
it doesn't look fun.
