Trackball was pulled out of a working machine. I replaced the shafts and threw in a new black trackball. Was going to use it for another project but havent had the time to build anything lately. I also have an OptiPac. I believe its the dual serial version although it comes with a serial to usb cable if you want to run usb. Not sure what these are worth to anyone. Shoot me an offer. If anyone has a LCD TopGun or Arcade VGA they want to trade, lmk. Also open to other trades...just PM me. I will get pics up tonight or tomorrow morning.
Thanks
Bill
