Hell, even today if a CME or something wipes out our electronics we'll have to go way back to vacuum tubes or even simpler setups to restore our society since most modern electronics need modern electronics to be designed and manufactured.

You can make something as complicated as a 6502 processor with just electricity for furnaces, motors, and pumps, without using any electronics.

You’d have to go back to hand-cut Rubylith for the mask sets.

Hand made transistors are no problem, just more expensive.

People still do this stuff for fun too. So it's not some lost knowledge.

I wouldn't be surprised if some colleges taught this as part of a history of computers course.
