Hello, I just purchased my first cabinet, a 1979 Williams Time Warp. When I bought it, it was able to save scores and settings. When I got it home after a bumpy 3 hour car ride the settings and high scores were erased. The seller told me it might have to do with a broken solder joint but when I look at the boards nothing is jumping out at me. The battery seems very old so I was thinking maybe I would replace that but I can't seem to find any batteries like this online. Looking for any advice as to where to start trouble shooting this. Thanks! Also... You can't see it in the picture but there is some writing in the cabinet near the battery that says it was replaced in 1991 lol, almost as old as me.
