(And upon slightly closer inspection of the RFC's header, it appears that
it was *written* in March of 1975, though Postel didn't post it until May
of that year. That certainly predates the V6 release by a few months, so
it seems probable that they were, in fact, running either V5 [possibly with
patches] or a pre-release of V6.)

Unix was on the ARPAnet circa 1975 (if not earlier):

V6 was "released" in May 1975, and that document was also published in May
1975 and says that the software had been running for about a month, so it's
entirely possible that the ARPAnet Unix work was done before V6 (or perhaps
they were an early test site: I don't know what the policies were around
that). It's been many years since I've read RFC681 closely and from my
quick skim just now, I don't think they say what version of Unix they're
running. It's clear from the RFC that they had been running Unix for more
than a month given the description of their site, and if I had to hazard a
guess I'd say they were running V5; perhaps heavily patched. I idly wonder
if any of that work has survived; it would be interesting to see an
ARPAnet/NCP implementation for early Unix.
But to address your question yes, Unix was certainly networked well before
UUCP emerged in V7.

Hi folks,
I was wondering if Unix had any form of networking before uucp
appeared in Unix v7. It would be interesting to know if one could pass
a file from one Unix v5 machine to another without having to store it
on a magnetic tape.
There's some reference to a mysterious "Spider Interface" in the Unix
v5 manual. It seems to have something to do with DR-11B (which is a
general purpose direct memory access interface to the PDP-11 Unibus).
There's also reference to the "Spider line-printer" :)
