Addendum: Cybernetics and its human application, bionics, crept into science fiction literature in the 60's, and was introduced to popular culture through the seminal 1973-78 TV series "The Six Million Dollar Man" (based on Martin Caidin's 1972 novel Cyborg). The most famous cyborg in popular culture must be Darth Vader; while to hardcore cyberpunk fans, it's Molly Millions from William Gibson's "Neuromancer" and "Johnny Mnemonic" (the story, at least).
