Another angle on this thing, since its only the mouse clock that's out, 
and it's supposed to be range 10 - 16.7 kHz, could I make a dongle with 
a clock source, there is info out there to take a PIC work with a PC  
mouse, and that's a separate issue possibly for the [PIC] list, just 
want to explore the dongle concept here. The mouse connector has 5vdc 
and ground available which should be adequate for a little circuit. Is  
that clock sync'ed with something, or just free running. Any other thoughts
