The Dougintology Department of Acquisitions is pleased to announce an addition to it's Museum of Technological Antiquities. This is a Philco Predicta TV from 1957-1958. I'm told it doesn't work,but to be honest I haven't actually tried. I found a guy who fixes these, but he has to hand make the parts. I should expect it to cost $500 to make it work. Of course, since the TV signals have changed since then it would be for playing the Pong system.
Yes, the museum has one of those, too.
