- "Good afternoon, gentlemen. I am a HAL 9000 computer."
– HAL 9000
The HAL (Heuristically programmed ALgorithmic Computer) 9000 computer is an artificial intelligence and the onboard computer on the spaceship Discovery 1. HAL 9000, more commonly called "Hal", became operational in the HAL plant in Urbana, Illinois, on January 12, 1992. His first instructor was Dr. Chandra. He is the hidden main antagonist of 2001 and a major protagonist in 2010.
Hal is capable of many functions, such as speech, speech recognition, facial recognition, lip reading, interpreting emotions, expressing emotions, and chess, in addition to maintaining all systems on Discovery.
The novel explains that HAL is unable to resolve a conflict between his general mission to relay information accurately, and orders specific to the mission requiring that he withhold from Bowman and Poole the true purpose of the mission. (This withholding is considered essential after the findings of a psychological experiment, "Project Barsoom", where humans were made to believe that there had been alien contact. In every person tested, a deep-seated xenophobia was revealed, which was unknowingly replicated in HAL's constructed personality. Mission Control did not want the crew of Discovery to have their thinking compromised by the knowledge that alien contact was already real.) With the crew dead, HAL reasons, he would not need to lie to them.
HAL speaks in a soothing male voice, always using a calm tone.
2001: A Space OdysseyEdit
- "I'm sorry, Dave. I'm afraid I can't do that."
– HAL 9000
Hal is built into the Discovery 1 spacecraft, and is in charge of maintaining all mechanical and life support systems on board.Hal also has several "eyes" placed periodically around the spacecraft. About three weeks into the flight, Hal picks up a fault in the AE-35 unit, the system responsible for keeping the satellite dish antenna aligned with the Earth, and states that it will go one-hundred percent failure within 72 hours. He suggests that they go EVA and replace the faulty unit with a new one. Dr. David Bowman goes out and retrieves the unit. But when he brings it back and runs it through diagnostics, they can find no problem with the AE-35. They radio Mission Control about the problem, and Mission Control says that Hal is in error predicting the fault. This is a bit of a surprise, as the 9000 series has a perfect operational record.
Noting that this kind of thing has always been because of human error when it has occurred before, Hal suggests that they go out and "replace the malfunctioning unit and allow it to fail. Then it should be a simple matter to track down the problem."
But by this time, both Dr. Frank Poole and Bowman are becoming suspicious of Hal's behaviour. They climb into one of the EVA pods, out of earshot of Hal. Poole states that he has "a bad feeling about him". Bowman and Poole suggest disconnecting Hal if he is wrong about predicting the fault. Unbeknownst to them, Hal read their lips through the window of the spacepod. Translating their lip motions, Hal learns of their plans for his disconnection; according to Clarke, "he (will) be deprived of all his inputs, and thrown into an unimaginable state of unconsciousness. To Hal, this (is) the equivalent of death. For he (has) never slept, and therefore he (does) not know that one (can) wake again."
Poole goes out to replace the supposedly malfunctioning AE-35 unit. As he drifts through space to the satellite dish, Hal takes control of the pod and rams it into Poole, disconnecting his oxygen hose and venting the air in his suit, killing him. Bowman, obviously distraught by the loss of his friend, goes out to retrieve Poole's body. However, while Bowman is out on his excursion, Hal shuts off the life support systems on the three astronauts in hibernation, which kills them all. After Bowman returns to the Discovery I, Hal denies him reentry into the pod bay. So Bowman has to maneuver the pod over to the emergency airlock. Unfortunately, in his haste to retrieve his friend, Bowman had not bothered to don the helmet of his life-support suit because he had not believed he would need it, making it very difficult to enter the emergency airlock, as he would have to travel through the vacuum of space in order to do so. This, however, does not stop Bowman. Risking the hazards of explosive decompression, he eventually gets inside, grabs a space helmet, and goes to Hal's logic memory center. There he pulls out the memory tablets that control Hal's higher functions. As his memory degrades, Hal begins to give off information programmed very early in his life, such as the date he became operational. When all his logic is gone, he begins to sing the song "Daisy Bell." His final act of consciousness is to play a briefing that Dr. Heywood R. Floyd pre-recorded about the Tycho Monolith before their departure, and the real purpose of the Discovery I's mission.
Hal is a major protagoinst in this film and is revived by Dr.Chandra once the Leonov reaches Jupiter, and prepped for his new mission of piloting the Discovery One back to earth. However, due a change of plans caused by TMA-2's disappearance, the crew of the Leonov is forced to leave the Discovery and Hal behind. Just before Jupiter explodes, becoming a star, Dave goes to Hal to send a message: "ALL THESE WORLDS ARE YOURS. EXCEPT EUROPA. ATTEMPT NO LANDINGS THERE." Hal is then saved from destruction at the hands of Jupiter as per Dave's will, and is transformed into a Star Child like Dave.

The computer's main objective in the story is to stop Jaime Sommers (Lindsay Wagner) from deactivating the doomsday device.
- The 2005 film Stealth involves an autonomous combat aircraft known as Extreme Deep Invader , or EDI for short (pronounced like "Eddie"). After learning how to disobey orders, the central logic system of the aircraft goes haywire after being struck by lightning and goes on a target hunting spree. The voice and demeanor of EDI is directly reminiscent of HAL-9000, even going so far as to include red luminescent camera eyes on EDI's central processor.
- In the Timon and Pumbaa episode "Forbidden Pumbaa", when Timon confronts the main antagonist (a robot) who has captured Pumbaa in a pod similar to the Discovery ones, Timon yells out "Okay, pal! Open the pod bay doors!"
- In the Season 5 episode of Mystery Science Theatre 3000, Mitchell!, in which Joel escapes from the Satellite of Love, Gypsy watches Dr. Forrester and TV's Frank have a conversation in profile, much like HAL watching Bowman and Poole in the pod.

Eventually, it acted like HAL 9000 and malfunctioned, making odd pizzas such as nurse shoe pizza and golf pencil pizza. Realizing what HAL was doing, Einstein came to the scene immediately and unplugged HAL.
- The music video for The Cardigans' 1998 song Erase/Rewind features a HAL 9000 reference along with a more prominent reference to Star Wars Episode IV: A New Hope. In the video, the band plays inside a room whose side walls gradually close in on them, much like the walls of the trash compactor in Star Wars; additionally, they are observed all the way through by a HAL-like 'red eye' lens, which, at one point, lead singer Nina Persson sings to. The video's two available endings have the band either escaping the room just as there is no more space for them, or being observed through the lens while the walls crush them - the video fades to black at the very last moment.
- On Muppets Tonight, an episode of "Pigs in Space" featured a HAL-esque computer called the "AL 1995 Plus Tax".

In the ensuing dialogue the computer has the last word: I'M PERFECT! ARE YOU? The dialog between man and computer was probably derived from the conversation between spaceman David Bowman and HAL 9000. Keith Emerson's vocal attribution refers to the 'computer voice' in Karn Evil 9 which says 'negative', 'primitive', 'limited', 'I let You live', 'What else could you do?' and 'I'm perfect. Are You?', produced by running his voice through the Moog's ring modulator.
- In a What's New, Scooby-Doo? episode, called High-Tech House of Horrors, "the gang ends up going to a future fair in Omaha; however, the main attraction the house of the future is closed due to the mysterious disappearance of a teenager.
