I've recently discovered that the J-Pac in my MAME cab does not have a duff EEPROM as I had long assumed as it was failing when attempting to program it. My model is just incompatible with Windows 10. I set up Win 7 on an old laptop and found it works no problem. Being that I VERY rarely need to reprogram it, keeping a whole machine around for that one purpose is a bit much. I might look into setting up a VM on my MAME cab's PC but for now I'm just interested in if anyone else has managed to program the J-Pac model I have under Win 10.
It's the middle model so no massive IC, but still has the two PS/2 ports (one for connection to PC via USB and a keyboard passthru.

I read on the BYOAC forum that some people had had success by using a PS/2 to USB adapter (yes, one of those green ones) connected to the port on the J-Pac then to the PC via a USB 2.0 male to male cable. This seems a bit odd as surely that's what my PS/2 to USB cable is already doing but who knows? Any thoughts?
