New to all this, here is my situation that I need help on. Acquired a S5500 that is set up for nickels. Replaced battery, cleared ram and then received 31 error, that continues to come back. This is based on the MPU dip switch set to .05. If I change the switch settings to .25, then clear ram, the machine plays with nickels just fine. The bill validator (IDO-44) accepts $1 but gives only 4 credits. Here is my question (S):
Is the AS-1200 super hopper universal as far as coins are concerned or would it require a mod to process nickels? The credits provided by the bill validator are they tied to the Dip Switch settings on the MPU? The game chips are for a 3 coin Diamond Winners. Would like to leave as a nickel game, but have to solve the 31 error, every time I change dip switch to .05. Any and all help appreciated.
