Jurassic Park, while beloved as a film, has been the subject of snarky memes for the infamous line in which one of the characters declares, "This is a Unix system, I know this!" while using a computer with an unusual 3D file manager interface.
Despite the memes, the film's production team was meticulous in accurately sourcing the right PCs (and adjacent details) for the sets—not too much of a surprise, given writer Michael Crichton's background with computing and his obsessive attention to detail in the book the film is based on.
