A friend has a JPM Thunderbirds machine which rarely pays out. Inside it has 8 DIL switches with ON another switches 1+2 and MORS above 6,7 + 8.
It has an input plug for a percentage key, what do the DIL switches do? And does he need a special piece of equipment to plug in to change the percentage? Thanks.
