TRIVIA

Discs of Tron was released in March 1983.

Also released as "Discs of Tron [Environmental model]".

Discs of Tron was originally designed to be a part of the original "Tron" coin-op, but was cut out at the end and set aside for refinement and release as a stand-alone coin-op in its own right.

Discs of Tron is inspired by the short sequence in the movie (Tron, 1982 Disney) where the character Flynn beats another trapped program and eventually 'derezzes' him, and when Tron is introduced, beating four 'computer players' very early in the movie.

David Bagenski holds the official record for this game with 418,200 points on June 28, 1986.

A Discs of Tron 'prototype' machine was shown at the 2003 classic arcade games show 'California Extreme' in San Jose, California.
