I was wondering if Unix had any form of networking
before uucp appeared
in Unix v7.
In general, no, but I know of a number of networked Unixes prior to V6.
ISTR that there were a number of Unixes attached to the ARPANET; I know at
least one (at UIllinois) was - that was a V6 machine.
There were several different TCP/IP implementations done under V6; the
UIllinois guys did one (in C), BBN did one (by Jack Haverty, who ported one
done in assembler by IIRC SRI), and one was done at MIT (by Liza Martin, in
C). I don't think any of them saw significant deployment.
