Me too. I have two drives of ca. 100-200 MB each, in boxes perhaps
1'x1'x8", and one drive of about half a gig in a rackmount unit that
takes up something like 8U or 12U (full-height), is full depth
(something like three feet?), weighs approximately what I do, and pulls
about 11 amps mains current briefly on startup, 4 or 5 amps idling.

The software-driven SASI port of what? The machine I want to use this
on is a NetBSD/hp300 system, a 319 or 320 or some such.

Darned if I know. The NetBSD/hp300 driver might have some of that in
it, but it also might not. I ought to go look.

I have what I think is probably an IEEE-488 interface for a SPARC (it's
an SBus card); perhaps I should try to scare up docs on it and see if I
can put it in a machine and build a disk server for it. That should be
sufficiently hacky. :-)
