I’m a little surprised it’s 1950, actually, if it is transistorised. The transistor wasn’t even invented till 1948.
Yes - I’m right - it is 1959, which explains the Sputnik design ethos. The first really commercial transistors date from around 1954, and the “universal” 2N404 dates from 1958. It wasn’t possible to build a really stable operational amplifier until silicon planar transistors came along, as those old germanium transistors were extremely temperature sensitive. But by the time the silicon planar transistor arrived, digital computers were already consigning analog to the scrap heaps of the Western world.
