My Johnny mnemonic is resetting randomly. I've had it happen during games, during test mode, and in attract mode. I recapped the logic supply, installed a new bridge and a psu5 switching lm323k replacement. Voltage is 5.04v on the mpu. Wall is 121vac. Happens when the game is cold or after its been on for a while. Are there any other culprits to check? Never had a wpc resetting issue that a power rebuild didn't fix
New! Dark mode!
