Thanks Mark, I did figure out what they meant, and I looked through the MAME config but did not find any mapping for them at all. I am using version .81 for my setup, did the CW, CCW setting not come in until a later version?
The diagram you reference did come with the purchase of my GP-Wiz49, and it does show all the key numbers, it doesn't really reference which ones would go to the default CW, CCw, etc.
Like I say, I think I am just missing something basic and the light isn't turning on in my head.
Thanks,
Marty
