I have an OLD ipac with 2 ps2 connections, one says kbd pass through, the other says PC usb/ps2
I am assuming that the PC usb/ps2 can be hooked up via USB? If so is there a cable available?
I also have a trackball from Happs Controls that has 3 buttons and a ps2 connection.
Is it possible to run the trackball through the pass through port on the ipac?
I am trying to set up my built controller so I can use it with a Retropie running on a r-pi3 (USB only).
