Howdy,
Trying to wire a Betson 3" trackball using a mouse hack. I have studied all the guides, and I have a PCB here that I can't seem to find. It is a Microsoft mouse, but different in the there are only 4 resistors on the board, labeled R1, R2, R5, and R6.
The optical parts are no problem, and neither is the red wires for +5V, but I can't seem to find where I would attach the black wires from the trackball.
Any help would be appreciated.
James
