Nothing except that I thought they were a more recent innovation. I was
thinking along the lines of, this is how you might build it with technology
available in 19XX

Can anyone give a timeline with (a) the invention and (b) the first commercial
availability of: PCBs, Transistors, ICs (perhaps divide up by technology and
scale of integration), and possibly other items of technology relevant to this
period (say, 1940 to 1970)?

Along similar lines, what multipin plugs were available at what date? In the
1930s and 40s, multipin plug and socket often meant something that plugged into
a valve (tube) base...
