UNIX timeline (was Re: PWB/UNIX)

[John F. Haugh II]

andy didn't include release 4.0, which as i recall was released in the
summer of 1981.  as far as i know it was only released internally and to
some universities which had professors on loan from the labs.

i had the misfortune of having to deal with it for a short time, prior
to xavier (where i hung out) getting release 5.0 running on the 11/45.
i can't say much about 4.0, except that it appeared to be closer to
5.0 than to 3.1 (did i get that right???  was it 3.2???)  we were having
hardware trouble so no one got to use the system much.

as i recall, 4.0 still fit in 128K or so of memory.  release 5.0 had to
be trimmed down quite a ways, and it still took more than 128K.  which
leads to the next question.  has anyone every managed to fit s5r2 on a
pdp-11?
