I have an old Ampex SASI card for the PC that you're welcome to. It
has a BIOS EPROM, but you'll have to figure out how it works--I
haven't much more than a pinout on the 50-pin header on it--but it's
all MSI TTL 7400 stuff; no PALS or ROMS. But you can also get a data
acquisition board with several 8255s on it in either ISA or PCI and
just use that (I know that some hate the 8255, but it shouldn't be a
problem in this application).
If you have ISA slots, building a SASI adapter is easy with a
prototype card that does all of the signal decoding for you.
