Quoted from Heretic_9:Total misread on your part. Not arguing, just inquiring. Relative newbie here, when it comes to pin ownership. Just trying to get better educated about these things -- that's all. Of my few tables, only one is later than the late 1980s, and that's the only one where I could see or identify a battery. I want to learn the things that I need to know.
This is the location of the manual for the Alltek:

(Look up the memory clear feature).
The board uses different memory locations for different games. Sometimes when you switch the board moving it from one game to another you end up with garbage in the memory locations the game uses. Clearing the board usually clears them.
The thing about doing that is that all the settings go back to default. So things like background sounds may no longer be enabled. The older games like Embryon had both dip switch settings, and soft settings. I think Embryon also has different soft settings for two different types of sounds, and which targets activate them or not. Those settings will be found in the Embryon manual.
