NOTE: A FEW BALLY GAMES HAVE A 5TH STROBE (STROBE5) COMING FROM A DIFFERENT MPU HEADER THAT ALLOWS FOR AN ADDITIONAL 8 SWITCHES (SWITCHES 41-48). THIS IS NOT PART OF THE NORMAL WIRE HARNESS USED WITH THE 64 SWITCH MATRIX TESTER SINCE THIS IS ONLY A VERY LIMITED NUMBER OF GAMES. SWITCHES 41-48 WOULD NEED TO BE MANUALLY TESTED ON THE GAME. SLINGSHOT & THUMPER BUMPER COILS WILL BE ENERGIZED WHEN SWITCH IS MADE IF TESTING IN-GAME. |
