Say... I got a board just like that one.
Actually not. I had 2, and then I got a third that was truly "new". I sold you the 1st one, this is the 2nd.
The one I sold you was slightly different - the footprint of the case was smaller and I think that yours was PS/2.
Different model number, too, I think - wasn't yours an RT101+?
They are all very close. I had a hard time deciding which one to put up for sale when you bought yours.
This one is just as nice.
