I'm sure this information is online somewhere, so I apologize, but I'm not finding it. I'm trying to hook the trackball from a dead Powerbook 170 to a Pico to use as a USB device. (I'm using extension ffcs so no trackballs will be harmed by amateur soldering!). I can see that it's a four-pin connector, I can see only 3 traces are used. I've gathered that they are +5V, Ground and Data, but for the life of me, I can't confidently find the order they go in. My best guess based on traces is: Data, +5, Ground, Unused. Can anyone confirm, because if I'm right I have a different problem? TIA!
