  It is definitely good luck.  I have a couple Q-Bus

I have managed to score a Qbus SCSI adapter or two over the past few
years, but I've longed for at least one Unibus SCSI adapter.  I know
they made VAXBI adapters, but when they were new, those were $10K for
disk _or_ tape, or $15K for disk _and_ tape... as such, there aren't
many of them floating around.  Lots of Qbus, fewer Unibus, damn few
VAXBI.
I'd love to throw a Unibus SCSI controller into my VAX-11/750 and play
around.  Except for the machine known as osu-eddie, I have very little
time on the 11/780, but I have wads and wads of time on an 11/750 -
initially as one of 30 users (8MB), later as one of 1-2 users (12MB).
I think a 11/750 makes a fine single-user VMS "workstation" ;-)
