Very interesting. I worked in a theater at a time when reels still were assembled and test screened usually the night before. Got to see the machines and operation up close and personal. Very technical and highly engineered equipment. Closer to clocks and watches than run-of-the-mill consumer equipment - might be of interest to have a look at the history of the devices!
