I have this board Dilog SU7 23A
Does anyone know this board?? I think it may be a SCSI controller. I
cannot tell if it is Unibus or Qbus.
Any help appriciated.
Sincerely,
John Welch

According to:
http://www.dilog.com/unibus.html
it's:
SU723A
SCSI, TMSCP, 7drives, Quad Height.
and (judging from the URL) it's presumably Unibus.

Thanks!? I did some searching but all The Google could find were a few
re-sellers that had the board but no info.? The 'feet' of the board (the
part that plugs into the buss sockets) are labeled C, D, E, and F so it
sort of smelled like unibus.
Have you ever used one of these boards?

Take a look at

Its only Unibus type device I have seen a Dilog Manual for. It might help you sort out the
Unibus addressing
if the basic design of the host controllers are consistent between products. Obviously the
media side will
be completely different.
