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

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.
