Modified Kidtrack
This is a large sturdy, full-sized, three button trackball, which is 100% Microsoft mouse compatible and very popular. The low profile case acts as a natural hand rest. The central green coloured key (situated at the back of the yellow ball) is a "drag lock" feature - simply press the drag button and the button stays 'locked' until you press a second time. Supplied with PS2 connector or USB connector. For PC only.
The three colour coded switch jacks allows easy switch operation of the left (blue) button, right (red) button and drag-lock (green) button . We can supply blue, red and green switches.
This device allows mouse-click access to all simple switch software.
