The IBM Personal Computer Keyboard was the first individually distinct and most common Model F keyboard. Debuting with the IBM 5150 Personal Computer (the original IBM PC) in August 1981 and later featured with the IBM 5160 Personal Computer XT (that gave it its common nickname), this keyboard played an important role in establishing the PC as a high-quality computer and solidifying buckling springs-based keyboards as IBM's go-to for well over a decade after its release. Relative the competition, the Model F/XT brought unsurpassed reliability and build quality to the mix but arguably suffered from a layout too different from others.
