DETAILS: I bought this game
along with a Food Fight from a local
collector friend who was looking to downsize
his collection. At the time, I
had another Quantum, but bought this one
because it was in such nice condition.

photos of the 2 known pre-production models
that have different artwork, visit the
Quantum Registry page.

FAST FACT: Quantum was originally
designed by General Computing Corporation,
who had infringed on Atari's copyright of
Missile Command when they made "Super
Missile Attack". Atari sued, and won,
and as part of the settlement General
Computing Corp. was mandated to develop 3
games for Atari. Those 3 games were
Quantum, Food Fight, and Nightmare
(Nightmare was never released).
