Inside the World's Greatest Keyboard

IBM's Model 5150 PC, released in 1981, was a classic, perhaps the computer most responsible for launching the PC revolution. (In fact, it's one of our 25 Greatest PCs of All Time.) Sadly, however, its keyboard did not live up to that standard. This 83-key model was IBM's first, and critics hated it, complaining about its awkward layout and nonstandard design. Stung by the criticism, IBM assembled a ten-person task force to craft a new keyboard, according to David Bradley, a member of that task force and of the 5150's design team. Their resulting 101-key design, 1984's Model M, became the undisputed bellwether for the computer industry, with a layout that dominates desktops to this day. As we peek under the hood of this legend, you'll soon see why many consider the Model M to be the greatest keyboard of all time.
