I think it was slightly later. I joined mid-1980 and VAXes to replace the
11/70 were being discussed but had not arrived. We needed to convert a lab
into a VAX machine room and decide between BSD and Reiser, all of which
happened in the second half of 1980.
Reiser Unix got demand paging a little later, and it was spectacularly
fast. I remember being gobsmacked when I saw a demo in early 1981.
Dead ends everywhere.

London and Reiser had ported Unix to the VAX, replete with virtual memory,
in 1978. By the time v7 was released (1979), Vaxen had become the workhorse
machines in Research.
