I grabbed a non-working lowboy Ultracade locally a while back and have finally gotten into getting it working. I replaced a fuse and the CMOS battery and corrected the BIOS and got the JoshuaOS running as it should. I've cleaned up the cabinet and rebuilt all the controls. I got the kick harness installed properly but I'm having a hard time getting the trackball connected. Does anyone have any documentation or know the pinout for the Jammalinx? All I can find in hours of searching is USBlinx info.

The connector for the trackball has much smaller pins and clearly won't even plug into the Jammalinx header. I tried to rewire it to a connector that will fit the pins hoping I could get signs of life on the P4 or Aux connectors but I've spent a long time looking for the right pins with no luck.

Anyone know where to plug the trackball in on this board?
