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).
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.
