Symptomes: Boardset powers up on bench, but keeps resetting after G bounces across screen. Does not boot up in game cabinet, keeps banging reset pin low. Will not run Spaeth RAM test. Does not run Diagnostics. Does not finish Attract Mode.
Verified all EPROMs with Fluke 9010a and reads correctly.
Current Fix: Found (2) bad 2114s on ROM/RAM board. Attract Mode runs on bench. Test Diagostics runs on bench. Boardset runs in cabinet with Spaeth Adapter reset tied to 5VDC. Screen is too red, that's next.
Found bad RGB board. Kept sending the cage into reset. Replaced with known working board.
Resetting issue fixed.
