2.11BSD is available from the Archives in various forms. (From memory)
the 11/44 and up, with the exception of the 11/60, had split I/D
address spaces of 64KBytes each.
[mutters to self... really must resurrect the 11/44 or 11/84.]

2.9BSD, as I recall, was the last release for
PDP-11's. Again, as I
recall, it did a pile of work to take advantage of the larger address
space (I think there was 64KI and 64KD).
I don't recall every seeing a 3BSD release.

But this makes me wonder if my 2BSD versions are newer than first
2BSD, so really 3BSD is correct for some of this.
I was asked off list what version of 2BSD as it may have been the 4.x
stuff backported. So it is the 2bsd.tar.gz from the
minnie.tuhs.org
archive (which is near identical to the spencer_2bsd.tar.gz). Its
TAPE
file says: May 10, 1979. The READ_ME says: Thu Apr 19 23:25:43 PST
1979.
And don't see any date stamps included in any files newer than May
1979.
(So not a backport since is 8 months older than 3BSD and 17 months
older
than 4BSD.)
