Adapting serial mice to quadrature systems

Hi,

Most mice actually start off with quatrature output position detectors and
are then converted to serial. I had to replace an Amiga2000 mouse once,
ended up removing the mouse chip and wiring the detector outputs straight
into the amiga mouse port - works fine - no PIC required.

secret PDP stash in this part of the world :)
