You need someone familiar with the skip field system AVCO used.
Good Luck

I agree that finding a working one would be the best bet.

One note of encouragement: "Hooking" at the top of the picture due to horizontal sync mistiming was visible mainly due to the slow horizontal AFC in TV sets at the time (done for best off-air performance). Later TV sets (and VCR/DVD recorder dual decks) have been built with faster AFC to accomodate the horizontal mistiming that may occur with any home VTR. So, I expect you could get reasonable playback into a modern TV set or DVD recorder.

Everybody I showed the chassis and "fish tank" electronics to thought I was crazy. How was a 16 year old kid going to get color tv programs with a black and white TV as the receiver. I was lucky, mine came with the camera and using a modulator I could trace out the video/audio in's and outs and even taped my cat to be sure I had the wires hooked up right. Those vidicon cameras neaded a LOT of light. Then I hooked up the video out of the 5 inch B/W monitor and hit record and pause and a color picture came up on the 19 inch monitor. First program I taped to show off to my friends was of course Star Trek. About 5 people came over, I crossed my fingers and pushed the lever for the play button and after about 30 seconds was a pretty good picture of Capt. Kirk. Everybody in the room wanted me to buy them one and make it work. Sorry, not without a supply of TV's with A/V out and inputs. A couple of years later Betamax came out for something like $1,700.00. It could be cool to be a nerd back then.
