My parents just found this dusty old treasure, and I took it home with me a couple of days ago. All the parts seem to be there, but it has only one output jack. The TV I'm using is fairly modern, so it has zillions of input jacks back there. No matter which one I use, I just get blue screen. Yes, I did switch the Atari to Channel 3.
I also tried using the video jack in the front of my VCR, but this was likewise fruitless.
What to do?
Will accept reasonable cash offers.
