Atari_Bill, The room we were in had a lot of rare items. The only Intellivision besides mine had the piano keyboard, which was pretty cool.
That would be mine. People seem to get a kick out of the music keyboard every year, so I keep bringing it. I would have done a more standard Intellivision display if I had known there wasn't going to be one at all. Usually the Underdog Chamber has one, but I don't recall seeing one running anywhere at the show this year, besides your Tutorvision and my Intellivision II/ECS.
