Trackball Roller Plus
Trackball Roller Plus
this trackball is marketed under several names
- Penny and Giles
- Roller Plus
- Traxsys
This one is beautiful.
The brown translucent cover is removable. The purpose of the cover is to prevent accidental clicks.
How much? I found $280 online, while another site is $400+. You'll have to search.

Spin Ball
the ball can spin, for about 5 seconds. Amazing.
Buttons
The blue button on lower right is a drag lock. (equivalent to holding the left button)
The button north of the trackball is X-Y switch. “ Pressing this switch once gives left-right cursor movements only, pressing again gives up-down only. To cancel this function the switch should be pressed a third time. Selection of this function is indicated by an LED at the top left of the unit.”
The lower left button, with picture of man running, is speed control button. Basically, a DPI switch.
