PACmate 20 Braille Display

The PACmate 20 is a 20-cell braille display with two pushbuttons over each cell, and two 'whiz wheels' (mousewheel-type wheels) on either side of the braille area. It connects to a PC or other device via USB, and can be attached to the PACmate notetaker to integrate them into one device.
