I am trying to use the trackball from an old laptop and would ideally like to connect to a PC using the standard PS/2 interface. However, the driver IC is made by Logitech and I cannot find the pinout for this device. I realise that it is made specifically for Logitech but I don't know where to find a pinout for it, if one even exists. I could try poking around with logic probes and might be able to identify some of the connections, but as I only have one of them I don't really want to destroy it by applying the wrong polarity etc!
I would be grateful if someone could point me in the right direction!
