A lot of companies probably did hand-draw up into the early 90s, or later. PCB CAD software really didn't come into it's own until probably the mid-late 90s.

hand routing a PCB must have been quite a skill back then

funny how people now use space age cad software to make basically simple widgets on 3D printers, or plastic green yodas

mostly yodas

It was quite the skill, you can always tell a hand routed board because the traces are all rounded. I just tossed a boatload of early hand-route boards, and some of those things were incredibly complex.

those mainframe boards were something else, 2 foot square with hundreds of TTL

I'm not planning on anything bigger than a Eurocard
