I was just given a Kyoraku L77 Pachinko Machine. I love the machine but it doesn't seem to work. I'm assuming that there is something wrong although it may just be something very simple. I purchased some balls and have put them in the rear tray as well as the in the front tray. The knob does nothing when I turn it. Am I missing something?

When I look at the back of the machine, the far right ERROR indicator is flashing. I'm trying to determine what that indicator is telling me. I've read a couple posts about adding a card reader dongle and jumping PC3 relay but I'm not sure that is what is necessary.

Any ideas?
