While the sentient computer installed in the lunar base in Moon is very reminiscent of 2001's HAL, the mental processes of Gerty - voiced by Kevin Spacey - are somewhat different, with more human-like co-operation than Kubrick's self-aware logic-led machine. It also has a small emoticon display to reflect its mood. Cute.
After our protagonist tricks Gerty into breaking programmers' orders, ignorance is shattered with both parties discovering the sordid truth to their existence. With conflicting orders - obey the corporation or provide support to its astronaut - the computer is left to make a moral choice and does so without the traditional motherboard implosion.

2001: A Space Odyssey (1968)
Even in this day and age, Kubrick's Space Odyssey blows me away. It's incredible to think all of that happened just a decade ago... In all seriousness, though, the film's Heuristically programmed ALgorithmic computer - more familiarly known as HAL 9000 - is one of the greatest computers
the world space has ever seen.
Capable of speech and facial recognition, lip-reading, natural language processing and, of course, an appreciation of fine art and music hall numbers, HAL 9000 is far more than your average personal computer. Brainy as it is, HAL turns fruit loop when ordered to lie to the astronauts in its care. To protect the mission, HAL panics and starts to kill everyone on board. You can hardly blame a computer for that.

Not a computer per se but the computer-controlled bomb in Dark Star is worth a mention, surely? Nice to see Holly in there though.
Perhaps the "Talky Toster" from Red Dwarf should get a mention, it's toasted bread products obsession was something to behold. I always thought of it as a Microsoft Product.
This list is broken, no mention of Orac or the ships computer from Star Trek.
