Giga Soft Mouse
The Giga Soft Mouse was one of the first mouse systems released for the Sinclair QL. This connected with an interface which plugged into the QL's joystick port (CTL1) (and unfortunately for power supply in the QL's ROM port) and provided a mouse with a resolution of 0.26mm
It came complete with both EASE (a desktop front end) and GigaBASIC a toolkit to allow you to create your own sprites and add pulldown menus to your own programs.
