I hear an interview with Kuberic years ago about that. He had asked IBM if he could use their name in the movie. After reading the script and seeing the rogue computer, they said "Hell, no!". Kuberic still needed to name his computer, so he DID subtract 1 letter from IBM to get HAL. It worked out well, because now the computer had a name that the crew could use to talk to it - I mean, the name is right there - HAL 9000!Do you know how the HAL 9000 got its name?
