I think so.  Back in the day, I couldn't afford a Split I&D machine of
my own and we didn't have any at work (at my disposal were 11/03,
11/23, 11/23+, 11/04, 11/34, 11/24).  The 11/44, 11/73, and 11/70 were
out of my reach (but not anymore!  Now, my problem is choosing what
disks to use, but at least 2.11 supports MSCP out of the box, which
allows for pain-free SCSI, etc., and I really ought to try playing
with the 2.9BSD MSCP patches).
