There may be some crossover, but Unix got it's start on the PDP-7 in
1969 I think--and it more directly ties its heritage to Multics.  Also,
V1 Unix was around in 1971, and V4 was around by 1973.  RSX/11M wasn't
released until 1974, so much of the PDP-11 AT&T Bell Labs Unix was in
place by that time.  If there are similarities, I'd almost suspect that
RSX/11M found some inspiration in Unix.

Wow, this is on tech-kern and not ClassicCmp or the PUPS list.
