anyone know how to make the coin settings save? when you change them in the test menu, they go right back to 1 coin 1 play no matter what setting you make each coin slot. even if you scroll around through the adjustments, the next time coin settings comes back around, its reset at 1 coin 1 play. all other settings work and save fine, just the coin settings have issues.

System 3 for reference..

tuff one heh?
BTW- replaced stock battery with holder and new 3v lithium even though voltage was fine and same issue exists

oddly SOLVED. you actually have to go one coin at a time in the menu. there is a hidden section kinda. 1 coin equals zero second coin in equal zero, 3 coins= in equals credit, etc. very strange. only 6 gottliebs were programmed like this. the 6 street versions.
