Golly! Ghost!

'''Golly! Ghost!''' (exclamation marks compulsory) is an electro-mechanical/videogame hybrid that was released by Namco in 1990. It runs on Namco System 2 hardware, and uses a diorama which is controlled by the game's driver board to open and close mechanical doors which are connected to solenoids, much like the movable items on a pinball table. The diorama has lights (24-volt globes) that come on only during gameplay to light up the rooms. All the lights are on when the game is being played during the shooting scenes and off for the cut scenes, title screen and high scores. The lights are not individually controlled, they are either all on or off. The driver board powers the diorama unit's solenoids and lights via some connectors on the driver board. The guns also plug into the driver board via another small connector.

A sequel named Golly! Ghost! 2 themed around sunken treasure was released in 1991, but only in Japan.
