I spotted THIS on eBay, and was surprised to see that the monitor included is a real Osborne GM-12 external monitor. I haven't seen one until this one. Check it out!
I don't think it's going to sell anytime soon at that price.
That last photo is how I know it's the real deal, as it's drawing both the video signal and power through the ribbon cable, which connects to that live edge connector on the front of the Osborne machines.
