What do these do? Credit Mult Bypass PC (from a Pac)

Anybody know what these guys do? They come from Pac/Ms Pac games.

They mount on the side of the cab and it has to be pluged in for the game to coin up. Supposedly there was some thing else that pluged into the harness(where the bypass board typically is located) for over seas use back in the day.
 
Yeah, in other countries, the cab had a logic board that would plug into this connector. It would multiply the # of coins to the # of pulses each coin would produce.

E.g. Assume the common "quarter-equivelent" coin in Germany was actually worth $1. The factory or op may set it up so that putting in $1 worth as a single coin would pulse the coin in 4 times giving 4 credits.

Conceivably you could have the opposite: Something that would take a 5 cent coin and wait until the 5th one inserted to send just 1 pulse to equal a normal 25 cent drop.

Other boards like Atari's had this built into software through dip switches: 1 coin 1 credit, 2 coins 1 credit or 1 coin 2 credits, etc...

These bypass boards simply ensure a 1 coin = 1 credit. There're nothing more than a jumper wire configured with a .156 header and foil traces.
