As the title says, I need a custom Bally I/O/audio chip. I've got a bad one in a Gorf. This chip was used in Gorf, Wizard Of Wor, Space Zap, Extra Bases, Sea Wolf II...and maybe Robby Roto (not for sure on this one...never actually seen a board set).
Most are AMI chips with the Bally number 0066-117XX. There's other numbers on the chip, but that's the important one. I've also found a chip with MA 0066 070BX...this one works too. And lastly, Bally released a service bulletin stating chip number 2720 is also the same. It's a 40-pin chip. Thanks!
