General Computer Corp. (GCC) is famous for programming "Quantum
" and "Food Fight
" for Atari. This was as a settlement with Atari after producing the unauthorized "Super Missile Attack
" hack of "Missile Command
". The settlement actually called for them to make three games. Nightmare was the third game, and it was never released. The PCB is actually loosely based on a "Food Fight
" board with many mods and a large daughtercard.
