Any other details? Can you tell what kind of processor it has, sound chip, etc? Looks like there's 12 chips with paper masks, the 8 on the left (which I assume are the PG1-8), then there's 2 more. What do those say on them?
When I was searching thru MAWS, one of the Phoenix sets did have PG1-PG8, but with the Bally sticker on yours, I figured it wasn't Phoenix (the PCB pic they had was different too...guess I shoulda checked crazykong.com too)
