Wow great answers everyone! I really appreciate hearing the perspective of my fellow people who collect vintage TVs
I have exactly three videotape machines, and none are VHS or Beta. one is an AKAI VTS -110 Monochrome camcorder, another is a Sony AV 5000A color videorecorder, and lastly a Hitachi SV-512 Time Lapse Recorder that I believe is monochrome and possibly was part of a video security system? (Not sure what other use there would be for time lapse video?) All three are open reel systems ("reel to reel" as it were) and I've saved them due to the relative rarity of such vintage equipment.
