I've looked for some video of through hole pick and place machines but have come up with nothing BUT, I do distinctly remember seeing pick and place in the movie Koyaanisqatsi (which is in my top five best movies of all time). Ironically, that movies was made in 1982. It seems 1982 was a very good year! Oh and for those who are interested, the story about how they made Koyaanisqatsi is as interesting as the movie itself. In some ways, hacking a Poly-800 is much like what Fricke and Reggio did for the majority of their work in that film. Everything they shot was done with old school camera/film hacking. That movie is truly one a kind and is a far more moving experience than any of the digital masterpieces of late. Interstellar being one of them - great movie! Yet, Koyaanisqatsi remains a quintessential experience. I thoroughly recommend it to anyone that has not seen it on the big screen. Do NOT see it on a TV, not even an 80" flat. Koyaanisqatsi must be taken in as a full cinema screen experience ONLY! Now where were we? Oh yeah, pick and place machines! /Rant over.

Wear eye protection! Breaking up those bakelite type sockets is an eye hazard!

Back in the 1980s I had a school holidays job assembling PCBs at the
electronics company my dad worked for. We built up roughly
eurocard-sized PCBs in a jig, which were using similar technology to the
Poly 800 - pick-and-place is hard with through-hole parts! That was all
hand-built, back then.

Sockets are cheap.
