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
at the core, which, obviously, is one of your goals) but it would
probably work.
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
base platforms.
