NCP and TCP operated in parallel on the ARPANET for a while. The
Internet Protocol Transition Workbook from November 1981 encouraged new
hosts to only implement TCP, not NCP, and says at that point there were
TCP-only hosts. On several occasions during 1982, NCP was temporarily
blocked, but TCP was allowed. What happened on flag day was that NCP
was permanently blocked.
So what I was wondering was: were there any VAXen talking NCP, or did
they jump straight to TCP? I`d like to see evidence, not handwaving.
