Technology Connections explains how 1970s pinball machines used relays, stepper switches, and electromechanical logic to track state and score without electronics.

Why it's here

What people say. Recommended for its deep and fascinating explanation of how complex game logic and state tracking were managed using simple electromechanical interfaces.

I've been watching his videos on a 1970s pinball machine. It goes horribly in-depth (in a good way). Fascinating how much complexity could be managed with the simplest of interfaces. link link to this video

On “Does DNA have the equivalent of IF-statements, WHILE loops, or function calls?”

After reading the reason why code isn't a good analogy, the mechanical/analog logic of old pinball machines might be a better example of how DNA processes instructions? Ref: link to this video

On “Can you get root with only a cigarette lighter?”

Yup - the first few minutes of one of Technology Connections' videos on electromechanical pinball machines shows this mechanism in action: link to this video

…e's state machine in a big function, haha switch statement go brrr. Reminds me of the old NES games which would statically allocate memory for game objects, very much in the "structure of arrays" style, they too had game logic just like that. Also reminds me of old electromechanical pinball machines. You can literally see the machine cycle. link link to this video…
