In article by Frank Wortner:
Bob's wish list includes a plea for DECsys and
the First through Fourth
Editions of Unix, but unless someone unearths a cache somewhere, these may
be lost to history. Too bad. :-(

A 3rd Edition kernel (ok, nearly 4th Edition) still survives at:
http://www.tuhs.org/Archive/PDP-11/Distributions/research/Dennis_v3/
We don't have any 3rd Edition application. However, the kernel can be
tweaked to understand the 5th Edition filesystem layout, and we have
been able to boot this kernel and run some 5th Edition programs on it.
Of course, the pipe system call is missing :-)
