      Today relays are an off-the-shelf component, but it was interesting to note that Williams were making their own custom multi-circuit relays for their machines. I assume that must have been common for any manufacturer who was making electromechanical devices of similar scale.

    This is fantastic. And it’s interesting to note, that the relay logic seen in how the machine was programmed is still used to this day in factory automation.

    Because factory automation was traditionally done with relays, they’ve created digital programmable relay systems called Programmable Logic Controllers (PLCs) which are incredibly common today.

    I love the running "joke" where he disdains computers or anything non-analog. Great video.
