✦ Synopsis

is a small lightweight keyboard which allows simultaneous input of alphanumeric and digitized data.

Its size (167mm x 100ram x 15ram) and weight (130g) make it suitable for use with Summagraphics digitizers. The RS232C interfacing (or on special order 20mA current loop) makes the keyboard suitable for most users.
