Two web pages devoted to real and fictional computers featured in the movies.
For real computers check this out:
Starring the Computer is a website dedicated to the use of computers in film and television. Each appearance is catalogued and rated on its importance (ie. how important it is to the plot), realism (how close its appearance and capabilities are to the real thing) and visibility (how good a look does one get of it). Fictional computers don’t count (unless they are built out of bits of real computer), so no HAL9000 – sorry.
Fictional computers are listed in an iper-detailed page on Wikipedia (where else?) which goes like this:
List of fictional computers. Computers have often been used as fictional objects in literature, movies and in other forms of media. Fictional computers tend to be considerably more sophisticated than anything yet devised in the real world.
This is a list of computers that have appeared in notable works of fiction. The work may be about the computer, or the computer may be an important element of the story. Only static computers are included. Robots and other fictional computers that are described as existing in a mobile or humanlike form are discussed in a separate list of fictional robots and androids.
Aren’t robots and androids computers, as well? Yes they are.
