I currently have an Atari Trackball from a friend here. It was in an unopened original CX22 box. It has two cables, one with male and one with female connector. When I turn it 90º clockwise it works like a ST mouse. The box has no markings suggesting is it an CX80... But it's some sort of CX80? Does other CX80 Trackballs behave like a ST mouse without rotating?
