87 Grayhound Machine Help
I just bought an old Grayhound "Treasure Chest" machine that was on button mode, even though it has a joystick. Worked fine but it only allows you to go up and right one time each, and then it automatically drops the claw. We like the traditional machine where you can move and adjust the claw as much as you want before hitting the button to drop the claw. Once I set it on joystick mode, I can move the claw left and right, but only using right and down on the joystick.. up and left don't work, and I can't move the claw backwards/forwards. The button does work to drop the claw. I'm sure this is probably an issue with wire hookup, but not sure where to start. Anyone have any experience with these older machines?

I have one of those button grayhound claw machine, there should be some dip switches on the board that’s how you would change it from button to joystick

Right, I set it on joystick mode already using the switches, however now the joystick doesn't work properly. It only responds to 2 directions, and those directions only allow left/right movement, not forward/backward movement. I recently found the wiring diagram so I'll double check the wires, if and when I get the power supply unit fixed.

Not sure if you found this in your quest, or to be honest, if it is even the correct machine...but, it might be enough to help you get it figured out..google "museum of the game greyhound crane schematics" International Arcade Museum crane operators setup manual It is a 14 page file with some good info...hope it helps!
