Hi All,
I'm helping a friend with a Fireball Classic that is not saving high scores. Voltage is getting to the board from the remote battery holder and the high score is even saved for some time after the machine is turned off then back on. But, after some time the high score is reset to factory settings. I've scoured the manual and found on page 8 a note saying that it is "recommended that the (HSTD) level, which will build with play, be periodically reset to the factory recommended level to encourage game play" but it does not explain how to turn this HSDT resetting feature on or off. So, I feel like maybe it is just me and I cannot figure out where the settings are for this feature so that my friend's HSDT can be saved and his legend can live on without the use of a sticky note.

I appreciate any help on this.

There is voltage at the terminals on the board. Is there a chip leg I should check voltage at?

Thanks a bunch for this. I finally checked into the issue and found no voltage at leg 22 of U8. Turned out to be a broken wire inside the battery holder. doh!
