Wow! You should definitely be able to get at least one working. If you determine it has baseband video and audio, that would be the way to go. If not, using the RF is a reasonable plan B.

They started long before then. The first one was in 1948. There were 70 cable systems in 1952.

There were also other reasons for having a 73ohm input. See the attached image from a 1949 Sylvania manual.

The audio in and out is on the connector that does not connect to the transport, the video in and out is on the same connector, I think it is the green one. Look at the wires going to this connector and you will see four shielded wires feeding it, 2 are audio and 2 are video. I hooked up the camera and started to probe the shielded wires center conductor with a small video monitor until I got the image from the camera on the monitor. Then did the same with the audio until I got feedback from camera mic to monitor speaker. Then the inputs were easy to figure out.
GOOD LUCK!
Richard

The 528 in the model number tells who built it-Warwick. I think Sears was their only customer. Later Sanyo took them over. The 312 on the crt means it was made by Sylvania; they sold to many other companies. Just as a TV, if it didn't have the catrivision, it would not be valuable but would be kinda rare...not many have survived. As a combo, a real keeper!

That console is a Warwick and was most likely made in their Forrest City, AR. plant (now Sanyo). It's definitely a keeper. I'll be watching this thread as I have a Cartravision unit I need to get going. Keep us posted on your progress.

connections

If I remember correctly, it was back in the early 1970's and I was 16 or so there is a switch by the camera input jack for camera or input from tuner connector, make sure it is on camera so it will pass the camera video to the connector you are probing. All my friends thought I was crazy that I could make this pile of wires and chassis record TV in color. The first show I played for my premire was a Star Trek (of course) then they were throwing money at me to buy one for them and wire it up. The hardest part was finding a TV that had video outputs, when I tried to tap the video of a regular TV it would draw down the signal. I would up using a 9 inch B/W Sony monitor and nobody could understand how I was getting color from a B/W tv. Oh yeah I fed the output through a Channel 3/4 modulator.

I was away from here a couple of days - glad to see someone jumped in with some answers.
Baseband composite video and audio is like what is on "RCA phono" connectors, usually red for right audio, white for left audio, and yellow for video on modern gear, but probably not existent on your set. So you have to play around to determine what you have.
Please do keep us informed on your progress.

Edit - I meant the connectors are probably not present, but as Richard D says, the signals are somewhere there on different wires or connectors.

Did the picture at any time have static or snow in it, or was it always gray no matter what deck you used?
