Picked up a Bally 6000 black and white 5 times pay, dead battery nothing on display. Changed battery, and noticed game proms (are they referred to as personality chips too?) Were backwards. I reversed them, and than actually got the 88ff.
Finally got ram clear chips in the mail, went to go clear it and saw legs Messing on the main chips ugggh. So I tried the clear anyways, no CH or anything, just two blinking lights. I assume the game chips are fried from being installed incorrectly
Need : game chips u18 and u20 for Bally 6000 (5 times pay) smi9329, or any percentage for this game, don't care (9330-9333 and 9392 I think are the series), plus a set of mains u28 and u43 that'll work for this game. Pm what you have and price to socal pls.
Would consider getting an entire MPU with chips on it already. Might be easier in the long run
***Found the chips***
