That would be my assumption, too - presumably they'd need more I/O lines than
the parallel port has available... (I'll see if I can find time to grab the

5380's are
VERY simple minded, and will work with little programming on
older controllers like the Xebec 1403 in the picture.
Yes, but interfacing a 5380 to a parallel port is just as hard
as a bit of glue logic. And, harder for him to come by
(I think I have a tube of them here from an old project...)
Actually, I almost certainly do have some amongst the cache of ex-workshop
Torch spares - I believe that chip was used in the Triple X (at the very least
I have spare Triple X system boards on which that chip will be socketed).
I'm not so keen on it as a preservation solution though (even assuming it
could be used) as it's not the sort of chip that everyone's going to have just
lying around; a bunch of LS TTL chips are a lot easier to come by!
Plus of course there's the issue of whether it'd happily talk to a SASI target
or not - quite possibly it's stuck firmly in SCSI-land.
