Ok, I thought it was just going to be a wiring issue with a dedicated ST upright. Well, blue and yellow is not coining up. Red and White is not coining up.
I've gone all the way back to the pins on the CPU board. Which pins are supposed to coin up? P7 nothing.
I thought it was 5/6 and 7/8. But shorting them does nothing. What wires are on your coin mech?
I'm wondering if it's the 74ls chip off of 5/6/7/8 pins of the cpu. But maybe I'm trying the wrong color. there's not much off of P28.
The only thing that coins the game up is the test switch.
