Ah, well, that explains it and also tells me that I probably do want to
ditch the chip.  There's no ROM/EPROM for loading on board (the rest of the
board is plain old TTL), which means the download must come from the driver
(which I haven't been able to locate).  Even if I took the trouble to
deduce the functioning of each I/O, I'd still have to come up with the
programming for the darned thing.  Not worth the effort, I think.    If I
can't patch something in with some TTL that will work, it looks like a
candidate for the scrap pile.
