Here we have a lovely full-page ad from Electrical Engineering, February 1948, extolling the use of Deltabeston power cables and wiring…over a million feet (5,200 miles) of it. It was produced by GE and was covered (and layered?) with asbestos. In any event I’ve paid attention to electronic/electric/analog/digital/electrical/mechanical description of the human brain, either described so or pictured with gears and tubes and such. This image from 1948 is relatively late for the early period of this sort of imagery.
This is the Mark II at Harvard, also known as the Aiken Relay Calculator, and was programmed by Aiken and Grace Hopper at the beginning of operations in 1947. It followed the Mark I, the famous wartime machine (the IBM ASCC, operational 1944), and preceded the Mark III (the ADEC, operational in 1951) and Mark IV (1952).
