Overview
Travel Time and Summer Time are electro-mechanical pinball machines released by Williams Electronics in the early 1970s, both designed by Norm Clark with artwork by Christian Marche.
Travel Time is notable for its unique gameplay mechanism where players earn extra time instead of additional balls, making the length of the game dependent on hitting specific targets to extend play. Operators can set the initial game clock between 45 seconds and 2 minutes 30 seconds. The game only ends when the clock hits zero and the current ball in play drains
The machine is well-known for appearing in the background of "That '70s Show" in the Hub.
