Thanks for your reply. Yes, the machine was working fine, both accepting quarters and using credits, before I stupidly hit the cash out button, but I have done that before without any problems. When I open and close the machine, the reels spin back to the double bars position (where I last hit) and the 962/40 flashes, which as you say is the payout/last win. Shouldn't it just go back to 0?
I did find a place where a key should go, and I know I don't have that key, but I don't think I should need it since the machine did finish the payout. thanks again. I love playing this machine and it's making me sad that it doesn't work.
