Zip-A-Doo

The Zip-A-Doo, manufactured by Bally in August 1970, is a two-player electro-mechanical pinball machine (model 874) with a "Happiness - Flower Power" theme reflecting the counterculture aesthetics of the era, designed by Ted Zale with artwork by Christian Marche.

Zip-A-Doo's notable features include two flippers, four pop bumpers, one mushroom bumper, a kick-out hole, and a center up-post. The maximum displayed score is 99,990 points per player. Bally produced backglasses for this machine in both crystal glass and Plexiglas versions.

With 1,083 confirmed units produced, Zip-A-Doo's flower-power theme and vibrant graphics are characteristic of the late-1960s/early-1970s counterculture-influenced designs that a number of manufacturers embraced during this period. It remains an appealing and reasonably well-documented example of Bally's EM output from 1970.
