Maybe you’ve seen this resource before, but here is a video about what computing was like at AT&T in the early 1970s. Believe it or not, sometimes I actually miss those days! [Warning: there is an inappropriate photo pasted to the console at 5:40. I do not recall such things, but I do remember a very large print-out of “Snoopy” across several sheets of fan-fold paper].
