Driver instructions for Summagraphics Summasketch 1,2,3

The Logic Group digitizing software can be used with or without the windows wintab driver, other vender software will generally require the windows driver. The digitizer can be used connected to the computer with either the serial port or usb port (using a serial to usb adapter from radio shack). A digitizing tablet manual is not needed to use the digitizer but one is available for download from the www.gtcocalcomp.com website.
