I'll post a summary (including wiring diagrams and a parts : list) if I can find the connectors. Hi, I managed to get the parts for the mouse. Included in this posting is a diagram for the pinouts that I used, followed by the parts list. It turned out that the DIN connectors are pretty standard, and can be gotten from several sources. I also included the original mail sent by Mike Andrews which I used as a basis for making the cable. Note that my pinout has XA and XB reversed from what was originally posted. Several people responded by asking what mouse I used. It's a Logitech MouseMan Bus mouse, which comes with a ISA card for PC's. Does any know whether the mouse can be purchased without the card? We plan on replacing several mice that are on their last legs, but don't want to waste the money on cards we'll never use. PINOUT: The following are pin placements for the connectors, looking at them from the solder pin view (the end your looking at when soldering on the cable). The numbers correspond the the 10 pin single row connector within the Logitech mouse. NEXT ------------ 6 1 3 10 9 7 8 4 LOGITECH ------------ 2 3 6 7 9 10 1 4 8 In addition to wiring the above with an 8 conductor cable, I added two diodes to the Logitech connector to allow the middle button to active both other buttons (used by many X packages to emulate the third button). The diode cathodes (the banded end) should be both be soldered to pin 2, the anodes should be connected to pins 1 and 3. I used low powered switching diodes which fit within the Logitech 9 pin receptacle.
