Interesting. In my head, v7 is kind of the pinnacle of what you should run
on a PDP-11 (yes, I know 2.11BSD is still maintained), but that once you
add a networking stack, the 16-bit address limitations really start to
hurt, no matter how clever you are with your overlays. But when I think of
v7, in my mind it's running on an 11/70.
I also find the multilayer switching described in the streams networking
implementation a lot like "inetd, all the way down." That's kinda nifty.

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.
