EVERYTHING used to be so complex. Before minicomputers all control systems mostly used relays, so a complicated AV automated system would have walls of octal base relays. We just only have the pinballs and juke machines left because all this was ripped out of industrial places since the 70s and replaced with PLCs and embedded controllers. The complexity is nanoscale and software now so harder to see.
- HeyLaughingBoy 2y agoI've posted about this before on here, but in the mid-90's I visited the group at the US Army Signal Corps that built their radio simulators. When you opened them up, there were just banks of time-delay relays and ladder logic. It was insane.
