http://minnie.tuhs.org/PUPS/ The 5 th edition seems to be the
earliest complete
version. Also the C language has changed a good bit between version #1
and #5 too.
Neat.. that pretty much covers it.
I liked the last part of the following quote:
"If you have a historical bent, then you can run 5th, 6th or 7th Edition Unix.
These tend to be limited in the hardware that they support. I'd recommend that
you use one of the PDP-11 emulators for these systems, as it will give you less
heartache then trying to install it on a real -11, and you probably will
get frustrated by these old systems anyway."
For anyone else interested, the above links to an article on the early
development:

And Ritchie provides some of his notes from 1972,
with mention of the DEC hardware supported:
