Fantastic as always Ken. I spent years of my life repairing IBM mainframes and I love these info drops. I guess its part of human nature to assume that our predecessors were dumb peasants (how did they build those pyramids?) but IBM had some incredibly sophisticated and elegant electromechanical, pneumatic and hydraulic systems in those days. The worst beast I used to work on was the 3890 check sorter https://en.wikipedia.org/wiki/IBM_3890 https://en.wikipedia.org/wiki/IBM_3890. This monster filled a (large) room, and when it was down, stress points went through the roof as bank's check sorting and money clearance ground to a halt. There's nothing like having a furious CEO leaning over your shoulder shouting at you while you're elbow deep in a dusty noisy furiously spinning machine to raise your blood pressure.
