Leaving the machine off (I'm assuming to cool) results in normal function. The button still dips the claw like usual. When you stop holding the joystick, the claw stops dipping. After that, I reset the machine and the forward and right controls work, but the left doesn't and the back (towards operator) actually dips the claw while the joystick is held. My wife and I played the claw constantly for over 100 plays, but after that the claw got stuck at the bottom of its reach, then retracted with claw open and stowed itself open. The claw operates normally for an hour or so. I plan on putting this on a route as soon as I have these gremlins worked out.įirst, the issue I'm having. Everything non electrical is more or less mint as it can be for an '80s machine. The board had had several hands on it by the looks of it, and I am not hopeful that I can restore it, its pretty rough. The cabinet its self is in great shape, as well as the claw and gantry.

It is the microprocessor driven board (CTL-1 Rev D) with joystick and sound. I am attempting to establish myself in my area on a very limited budget, so I bought a Betson Big Choice claw machine on the cheap (100 bucks) because it had a few electrical gremlins.
