Very few people HAD a computer in 1982, except for tech-geeks and office cubicle-drones (or professional programmers)--
So most of the "computer vibe" the movie had to sell its marketing to were the arcade-game kids, promising "Live-action Pac-Man!", and it...wasn't quite that.
Nowadays, the humor plays a bit better, now that we're a little more computer-literate enough to get the tech-geek jokes.
And, of course, at least it had a sense of humor, compared to its grimly and preemptively reverential '10 update, determined to enshrine the original in "rave" culture.
