xerox to symbolics conversion

This describes the connections to convert a Xerox 3 button optical mouse (15 or 9 pin connector) to be used with a Symbolics machine. Earlier optical mice have the 15 pin connector, but the one we bought in winter of 1988 came with a 9 pin connector. Included, is the pinouts for the custom IC used in the optical mice for persons converting the mice to a different machine.
