IBM 5151 Monitor, New In Box!, Model 5151001, tested.

I’ve dealt with a good bit of vintage IBM merchandise and I’ve never seen a monitor new in box like this before. I have no idea how to price this so please send offers if you know better than me. Buy it as quick as you can if I grossly underpriced it, I’d appreciate the business either way. I tested as best as I could with a CGA card. The video output I have doesn’t do vertical control with monochrome, sorry I couldn’t get a good picture of the screen because of this. I can say that the green phosphor is amazingly bright and I’ve never seen a monochrome this mint before.
