Title: Bally 5500 what U3 U4 U12 & U15 goes with Post by: badbaud on September 08, 2010, 01:33:57 AM Red Hot 7's - the customer has a 94% machine and wants us to put in a set of chips for the 85.84% payout.
We have the SMI 7419 84.84% and the SMI 7420 for the 88.99% game but can't seem to find the set of U3, U4 (SEQ?) and U12, U15 (MEQ?) that will us to get the game running. Trying the sets we have in stock only gives us a slow flash of the lamps on our tester indicating "bad EPROM match". Does anyone know what the number's are on the chips that would work? |
