I found one of these locally, then looked them up online. They're certainly not rare, typically coming with few different input cables due to the model they were paired with.

Since these were for cameras do you think they'd be a decent (even though just black and white) picture? I'm wondering if I could pair it as a monitor to one of my micro computers.

It porbly is just standard composite monitor. so that would porbly be pretty easy to get working. However it looks like it uses a din plug so I would try and find the service manual. So you can figure out the pinout of the plug. Aslo dose it plug in to the wall or dose get it's power from the camera it original came with.

I'm into semi useless stuff, so I'll pick it up.
