Hey, everyone, thanks for your advice and support. Wayne Eggert at Pinitech.com set me up with a 5101 NVRAM replacement chip and it works great. It arrived yesterday and I installed it while i was home for lunch...and I was late getting back to the office. EBD lives again! My boys and I are so pleased that we decided not to put the game back together right away. We're going to shop it on Saturday afternoon. Parts will be here later today.
I've been a pinball nut since I as a tyke. I'm 57 now. This hobby wouldn't be near as much fun without the Internet and people like you willing to help out your brother pinheads. I'm proud to be a member of this fraternity.
Next up for repair and shop service...Six Million Dollar Man! There's a tech issue with that game, too, so you'll be hearing from me. This is going to be an important repair because my older son wants this game in his apartment at college next fall.
