What is an ENABLE board?
That's that thing we had an 'energetic' discussion about a while back;
it's a
board that allows one to put more than 256KB of memory in a UNIBUS machine
(other than a /44 or /70, which already support more than 256KB - and probably
the /24 too, too lazy to check).

Did 2.10 require split?

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).

Yeah, the 11/24 also supports more than 256K.
However, at least the ENABLE board that I used on an 11/34 did not add
neither split I/D space, nor supervisor mode. Essentially it made the
11/34 look like an 11/24.
