I think I have 4 or 5 of these boards in storage. Besides the trackball games, these were a strange configuration. Three buttons each. They were a big earner back in the day, and I remember the kids would use the sleeve of their school jumpers during the 100m Sprint and rub it left and right across the buttons. It was easier than using your fingers.

Do you need a special cab for these Nino? I'll talk on Wednesday re: boards :-)
