OK/Red Letter Game - Super OK
Super OK is a feature unique to Bounty. If lit and the current red letter is one of [NTY], super OK is does nothing. If, however, the current red letter is one of [BOU], you plop two balls in the orange section and collect the OK win, then the game resets to the "N" level settings.
On earlier games, this could have been implemented by stepping up the red letter unit so it was no longer in sync with the green scores, but the new design uses the green score unit to drive the ok/red letter function.
The only simple solution is to step up the green score unit before the ok/red letter unit starts stepping up the various units/trip relays, but after the position 29 relay is powered to indicate an ok/red letter win is being collected.
The blue circuit takes care of that. When the super OK feature is enabled, the pulse stream entering at the top on the purple circuit is directed along the blue path and is used to step up the green score unit. Note the position 29 relay switch highlighted in yellow is open so the pulse can't sneak off elsewhere.
When the green score unit steps up high enough, the super OK relay is unpowered and the switch flops the pulse stream back along the purple and green branches where it can do the ok/red letter unit and other unit step up functions.
I won't show the circuit that is operating the super OK relay. It's around D-17 on the Bounty schematic if you want to look.
