Hey everyone, working on a Capcom Airborne. Had multiple problems at first but we have narrowed it down. Basically, to make a long story short, the problem is that when we turned on the game, the CPU would not finish its boot sequence and the game would bog down. After some triage, we narrowed it down to the optos. When the opto power is plugged in (J15 on power board), the optos do not work and it ends up bogging down the CPU and game will freeze up. If we unplug the optos at J15, the game will boot fine and go into attract mode.
When we put the DMM on the power board at the opto pins the voltage is 10v. Does this make sense?
Anyone else notice the capcom airborne manual doesnt match up with the boards.
Any help appreciated.
