operating analog telecom switches, Feb 2017, Seattle's Museum of Communications

Seattle's amazing and little-known museum of analog telecom technology, where fascinating volunteers, young and old, with a culture all their own, preserve and operate huge analog/mechanical telephone switches of various eras dating back to the early 1920's. A geek's delight! No video can do it justice. Beware: having seen this, you'll have to experience the whole museum yourself. There's much more to see.
