HAL 9000 was the artificial intelligence on the space ship and responsible for killing the crew after going a bit schizophrenic. Famous for his quote "I'm sorry Dave I can't do that!". In the film the name was never explained but it has become to be an acronym of "Heuristically programmed ALgorithmic Computer ", tho' some people think it is a jibe at IBM, since if you use the next letter over in the alphabet from IBM you get HAL.
