We had NCP running on the JHU kernel which essentially a V6 kernel with extra stuff
(including the ability to mount both V6 and V7 disks). This was done on an 11/34 at Xmas
time 1982 when the Arpanet went to long leaders and the UofIll ANTS we had became
obsolete.

Ah, OK.
I have seen references to it in the ARPAnet
census documents running on
both V6 and V7 (though mostly they were silent about which version).
Well, V7 came out in January, 1979, and NCP wasn't turned off until January,
1983, so people had a lot of time to get it running under V7.
I thought this was the normal nomenclature of the
time, but I may be
mistaken.
I'm not sure what it was usually called; we didn't have much contact with it
at MIT (although I had the source; I'm the one that provided it to TUHS).
The problem was that although MIT had two IMPs, all the ports on them were
spoken for, for big time-sharing mainframes (4 PDP-10's running ITS; 1
running TWENEX; a Multics), so there were no ports available to plug in a
lowly PDP-11. (We were unable to get an IP gateway (router) onto the ARPANET
until MIT got some of the first C/30 IMPs.) So we had no use for the NCP Unix
(which I vaguely recall was described as 'the ARPANET Unix from UIll').
