I was in the basement of UCL computer science (in the Pearson
building) in 1988. Our lab had a very special yellow (Don't ever touch
that!!) cable that ran across the ceiling between joists, then off
under UCH toward Telecom tower. Of course we hung bits of origami on
it with cotton. Apparently that was JANET. I never heard anyone say
"The Internet" back then, but we did have a coms lecture where
"inter-networking" was a thing. Nice to read some old names in that
piece.
