The Columbus Unix was also running on VAXen, but I don't have great dates for that and most (all?) of those machines were confined to internal AT&T. I recall reading, but don't recall where I read it, that the Urbana networking was ported to 7th Edition. I tried to find such source, but couldn't 18 months ago. 32V is basically the same as 7th Edition, so would make a good candidate for such a port, though 3BSD isn't so radically different, except in buffer mapping, that it couldn't run there w/o much effort. The VAX never had a V6 port that I've read about anywhere, though I'll defer to others with better sources. I'd bet some $$$ that BBN did the port, but I have no good source for that either.
