My intention is to make either an HP-IB to Ethernet
Hmm... a couple of ethernet projects for the C-64 just hit the public
eye in the past few weeks, and there's beeen HPIB cartridges for the
C-64 for a long time... Wouldn't be as fast (and it wouldn't be an HP

Another option is to drop a DEQNA into a MINC (which typically had
an IBV11) - you could even run 2.9BSD on it with a KDF11 processor.
Not sure what to use for disk (probably need 5MB minimum, 20MB would
be better). I don't know if there's a driver for RT-11 for the
DEQNA, but that's a possibility, too.
Most of my HPIB experience comes from the Commodore world. I know
that the physical-layer stuff is fairly consistent (presuming your
devices can keep up - not guaranteed if you want to use a modern
peripheral with, say, a PET). The "problems" are usually related
to the command set, AFAIK. I'd love to see what you come up with
for a command structure for an HPIB<->ethernet gateway. Perhaps
it would be adaptable to other hardware (PeeCee w/HPIB card, PDP-11,
etc.) I know that I will probably never own an HP9000 (just not my
area of interest), so I'm looking at this with an eye toward other
