I recall V7 had UUCP and that some non-tcp/ip
networking
implementations existed for it,
Yes, various serial-networking based ones (early
DECnet, X.25
and PacketNet stuff) and perhaps the multiplexer device stuff.
but I have never heard of a tcp/ip stack for V7.
Does
such a thing exist?
Nope, didnt fit in the address space. As far as I know, the
earliest TCP/IP UNIX for PDP-11 was 2.10/2.11bsd.
