If you peruse the maps at the Computer History museum
site you can see
some real diversity in the systems. For instance in April 1971
Burroughs had an IMP and a B6500 front-ending the under-construction
ILLIAC-IV (later moved to Ames and front-ended by a couple of
PDP-10s). PARC's MAXC appears in the mid-1970s.
Maybe this is a good time to ask if anyone knows whether any of those
diverse systems has software preserved? Specifically, the
implementation of the NCP and 1822 Host-to-IMP protocols?
