Noticed that some of my scores didn't end in 00, too.
I mean, that's a pretty good error-check there - pinball scores always end with at least one 0, and you might well assume that in the computer they're stored divided by 10 and then there's a dummy display digit that's always 0, and that was true on electromechanical games but on solid-state games the computers actually store the whole score in memory, meaning that a score that doesn't end in a zero is a REAL NICE CLEAR OBVIOUS INDICATOR that you've got PROBLEMS, maybe a RAM chip's going bad or this thing got hit by a particularly angry Cosmic Ray or something, either way take the dollar bills off the glass 'cause these scores ain't valid uh I mean no gambling amusement only
