Due to popular demand, I've made a video all about the RCA Videodisc system.
This was intended to be a quick and simple look at an obsolete technology, but somewhere during the course of the four problem-filled months that it took to put this video together, it went off the rails and ended up as a half hour video documenting man's struggle against machine(s).
It's like the youtube gadget-review version of Fitzcarraldo.
Some useful links:
CED Magic - The Website for everything about CED. Includes a full catalogue of every disc released.
The Full Electron microscope video on the Applied Science Channel can be seen here on youtube.
If you buy an old Hitachi player you'll need to replace those two rubber belts shown in the video. These can be purchased in the UK from CPC Farnell - here's the link
