on that picture, UCL would have been running triple (or maybe even
quadruple) staccks - we had the x.25/colour book (you did i think),
and the cambridge ring stuff, as well as some weird port expanders and
so on......
to get email between 2 pdp11/44s on a cambridge ring at one point we
used to use the external loopnack on an LSI/11 satnet (simp) interface
as far as i recall which meant that in theory, email goijng across the
room went about 35,000 miles....so you could say that the
interplanetary internet started in the earlie 1980s in a small
basement room....
