As long as we’re talking about analog video, I can’t stop myself from throwing Dan Sandin’s analog image processor in there. Think the principles of a moog synth, applied to video signal. Here’s a totally amazing video of him demonstrating the machine, circa mid 70s:
Sandin also had a distribution philosophy that was a precursor (early contemporary?) to FOSS: he called it “copy-it-right”. He’d send anyone a copy of the schematics, but you were expected to build it as designed and not get creative until you at least had it working properly. The process of building the machine was also supposed to teach you how it worked.
Many moons ago I emailed Sandin and got a copy of the plans. They’re a hell of a document. Unfortunately some critical components are no longer in production, and updating the schematics was beyond my skill (setting aside that the scale and expense of the project was also beyond me, but hey).
