I just picked up a sinbad adventure pachislo. It has a two prong plug and also has a seperate wire that runs as a ground right next to it. Do I have to plug the ground wire into the screw in the middle of the outlet or can I leave it alone? Should I change this to a three prong plug? Also could someone post a picture of the inside of their sinbad. Mine came with a few things loose and I think I got them back in the correct area. Also is a 110 transformer okay for this machine. Any information would be appreciated.
