Quoted from MarkG:According to the schematic the drop targets only reset during startup or when he Player Unit advances. Extra ball prevents the Player Unit from advancing so I don't think the drop targets should reset in that case.
The Double Bonus relay is a trip relay so once it trips it stays tripped until the Player Unit advances or the game resets (same as the drop targets). So I think it would persist through an extra ball too.
Would this hold true for the ABCDE sequence as well as the drop targets? Mine does not reset either when an extra ball is served up.
