Came across a Watara Supervision at a thrift shop in Seattle. This is a particular system that I have never seen in a shop. I got mine on E-Bay. The screen had a black mark on it that looked like it could have been a busted LCD, the casing, screen, and hinge however were in near mint condition. There was a mysterious cartridge taped to the back of the system. I snapped a couple blurry photos with my iPhone.
