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. -ethan __________________________________________________ Do You Yahoo!?
