To bring it back to the Atari 800, I remember magazines like Compute and Antic having breathless headlines about how Atari and Commodore played some big part in making the movie. As the new owner of an 800 in 1982, I was quite excited by this. Thinking my Atari could render a lightcycle! Turns out, it was minor sound effect work done on the Ataris. That wasn't quite as exciting.
