UNIX-32/V was the second version of UNIX I used, on a big VAX-11/780 --
just after getting my feet wet on a PDP-11/60 running V7, at the U. of
Calgary. We continued to use those machines for the two years I was
there, though quickly upgrading the VAX to 3.9-BSD, 4.0-BSD, and then
4.1-BSD just after I left. When I visited a year later, they were
running ~64 terminals that VAX! The 11/60 had been upgraded from 16
terminals to an 11/44 with ~24 terminals too!
It is my recollection that 32/V came from Berkeley, but was done by one
of the AT&T'ers who was there on sabbatical (ala the reason BSD got such
a foot in the door).
