Hello,
I've picked up a Daytona USA twin in rough shape. One side starts ok (set in freeplay mode) but the volume has to be set to the max. It is way way too loud. The coin box wasn't included and I think that's where the service button and volume control would be. What are the buttons for on the I/O board? Are they redundant buttons for service mode, etc? Is there a pinout for the coinbox mechanism? I can see an unused molex in the back of the machine.
