I'm eight years to the day older than Rob, so I got to work with even earlier technology than he did. As far as I know, Rob never encountered the IBM1401, the PDP-7 with its 340 display, the Titan and its time-sharing system, 7-hole paper tape and Flexowriters, or the horrible Data General Nova mini-computer. I never used an IBM System /360, but we did both work with CDC machines, and punch cards.
I think Rob and I started on PDP-11s at about the same time in 1975, me on RSX-11M at Imperial and Rob on Unix at Toronto. Rob was always much closer to the center of the Unix universe than I was in the UK, but the Unix history he recounts was mine too, from Version 6 on. Rob's talk is a must-watch video.
