I spotted it sitting in an alleyway.
For those who are into microcomputers you may notice it bears a striking resemblance to Tandy's monitor for the TRS-80 model I. That's because it's the same set but with the tuner and speaker removed.
I happen to own one of these systems and this is awesome because the expnsion cabinet has indents designed for the feet on this set and the ventilation grilles line up.
Tandy swaps out that vertical standing board inside with their custom board full of magic. There are no documents on what this board actually does that I can find so I'm forced to use an RF modulator instead of any kind of direct connection.
Anyways, the cord had been cut but when replaced I powered it up and man she wasn't happy.
It's hypnotic. The image oscillates and the speaker gives off an angry buzz. This will be a fun one.
