I bought this IBM SpaceSaver II keyboard from UpgradeBay a few weeks ago. They were listing it for about 140, but I wanted to play around with having no external mouse. I ended up using it for a few days and opting for the filco keyboard instead.
I've attached a photo of it. A few notes: there is a light scratch that it came with on the N key. The keyboard is also PS/2, and did not come with any drivers (you may have to dig these up).
I can post this on eBay if anyone wants, but I would prefer just to sell it to someone here thats interested over PM.
I'm thinking $90, if that's reasonable.
