Based on that extra info I think you have a later version of Network Unix, which
is still wonderful and exciting.

Wow, that's great! That means that you have
the initial version.
The file write dates are May 1979, so that's the latest it can be. There is
one folder called 'DTI' which contains an email message from someone at DTI to
someone at SRI which is dated "10 Apr 1979" so that seems to indicate that
that's indeed when they are from. I could have sworn that I'd seen _listings_ of
the code in a UIllinois
document about NCP Unix that I had found (and downloaded) on the Internet, but
I can't find them here now. I did look again and found:
"A Network Unix System for the Arpanet", by Karl C. Kelley, Richard Balocca,
and Jody Kravitz
but it doesn't contain any sources.
The initial 1975 implementation was - in the authors' recollection - only some
one to two thousand lines of extra kernel code and one thousand for the NCP
daemon. That would make for some 50 pages of printout. It is possible.
I know the Kelley document well and sections 5 and 6 contain a fairly
detailed code walkthrough. Perhaps this is what lingered in your memory.
I suspect this (Oct 1978) code walkthrough will match with the code on your
tape.
