Boy, if you don't know, then who is... But this brings up another good
point, where to get the older CTuL logic IC bus drivers (the 9956 in
particular) besides from old boards? I'll probably need a few to make my own
I/O boards, else I'll have make my own level converters out of SMD
components...

Subject: HP board id?
It seems over the years I acquired more than a just a few of these (two
types of) boards for the HP1000. I'm pretty certain they all came from a
batch of about twenty HP 1000 series systems I got that were decommissioned
from military use. They do not seem to be HP in origin, and I don't have
any
clue what they are for. Mostly they seem to be stuffed with large numbers
of
op amps and some line drivers. Perhaps just flight line testing or ATP?
If no one thinks these are of any use. they will be scavenged for bus
driver chips. But I'd hate to do that if they might be historical or
"interesting".
A few pictures of each board are at www.ezwind.net/hp-unk
Educated guesses?
