The flyer refers to the "exclusive" Bally "Game Brain" circuit board. This is a different "Bally Brain" than the original Bally's 1974 'Flicker' prototype. A 1999 GameRoom magazine article indicated that David Nutting of David Nutting Associates signed an agreement with Midway in 1976 to produce home versions of pinball machines, using his company's "Bally Brain" invention. The Bally Brain of the article was a 4004-based unit installed in a Flicker pinball. The Bally Brain of the Fireball/Galaxy Ranger/Evel Knievel/Captain Fantastic home professional series used a Fairchild F8 processor for series 1 and a Mostek 3870 for series 2 and is based on the architecture of the original Bally Brain.
