How pcbs were made in 1969

is it really an analog circuit if you make it on a computer anyway !? :wink:


is anything analog if quantum mechanics holds up as a fundamental theory? not a troll question, something i think about a lot. for my classes i usually go into digressions on how “analog” video can ever be, usually the point i try to emphasize is that anything with discrete components beyond a certain liminal point is nearly always indistinguishable from a “continuous” signal but ive always been leaving out the quantum nature of light and electricity and wondering how much that rabbit hole is worth exploring for practical purposes
