SummaSketch Plus Graphics Tablet

The SummaSketch Plus is a graphics tablet produced by Summagraphics. The tablet is controlled via a specialized custom pointing device that is moved over a 12"x12" grid space, and has four toggle buttons that perform various actions depending on what software is being used. The pointing device is hardwired into the rear of the unit along with the combined power/data cord that goes to a parallel port connector with a power brick attached feeding +12V and -12V into the unit. The bottom of the unit has an extendable support that can also be adjusted to prop it up higher on a table.
