Released in March 1983.
Also released as "Discs of Tron [Upright 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.
