Last night I fired up Joker Poker after not having it powered up for a couple months. It had 68 credits on it! I launched plenty of first balls, started four players, and repeated. I got the credit counter down to 9 credits and then shut the game down. My son turned on the game today and he reports that it has 68 credits on it again. I had a similar problem last week with my EBD game, but a purchase from Pinitech.com for a 5101 NVRAM upgrade solved the problem. They don't have such a chip for the Gottlieb System 1 games. Any thoughts?
Thanks!
