In true RayB fashion, I'm going to avoid your question (which I don't know the answer to Grin ) and will instead say... That's a rare game! (I think???)
I don't know how rare, but it seems that all Eight Ball Action machines were conversions of either a Donkey Kong, DK Jr. or a later Pac-Man conversion.
What's weird is that just about everywhere I've seen these, they are a joysticked game. I saw this up on eBay for $89.00 starting bid with the trackball.
Wouldn't be a bad buy, would probably convert and restore the cab back to DK, but that trackball has me intrigued.

Anyone have more details about this?
