Zip-A-Doo

Released by Bally Manufacturing Corporation in August 1970, Zip-A-Doo is a "Happiness - Flower Power" themed electro-mechanical pinball machine designed by Ted Zale with artwork by Christian Marche. Bally produced 1,083 units of this two-player machine, which was assigned model number 874 with a project date of December 30, 1969.

The playfield features two flippers, four pop bumpers, one mushroom bumper, one kick-out hole, and a center up-post. The game offers a maximum displayed score of 99,990 points per player. The backglass was produced in both crystal glass and Plexiglas versions, reflecting different manufacturing techniques of the era.

Zip-A-Doo embodies the late 1960s counterculture aesthetic with its flower power theme, making it a cultural artifact of its time. The machine represents typical Bally electro-mechanical engineering from the period, offering straightforward gameplay mechanics that were popular in arcades during the transition from the 1960s into the 1970s.
