I have 3 old video cameras from 1983-1984 that use vidicon tubes (or as Sony called it, the Trinicon tube.) They are one of the first consumer all in one units: Sony Betamovie BMC-110. I have that one, and an identical Sanyo and Toshiba clone of it. Image is very smeary at times, and white balance was kinda crappy. Manual focus. These were record only with one head.
