If anyone can help me out with information or advice I'd really appreciate it. In the new year Im having my TAF totally rebuilt. It currently has the gold ROMs fitted. As everybody will no doubt know, at the end of the gold version game an extra ball can be bought for 1 credit. Obviously original TAF cabinets dont have the extra ball button. Does anybody know if a small conversion can be carried out to the wiring to facilitate an extra ball ball button being fitted? Thanks, Jon.
