I have a Nishijin from the mid 70's or so. When balls fall into the pockets, they fall onto a surface below instead of out the back. The tulip will open but the jackpot won't pay out. However, the lever on the back toward the top of the jackpot will cause it to pay out, as normal. I took some photos. Any thoughts, anyone? Thanks a bunch. I like this machine and would really like to get it up and running.
