Happy 45th Birthday to the IBM PC and Model F/XT

On August 12, 1981, IBM launched the Personal Computer (IBM PC), fundamentally transforming the computing landscape by introducing x86 architecture to mainstream offices and homes. The article credits much of the PC's success to its well-built Model F/XT keyboard, while noting that IBM-compatible clones played a crucial role in sustaining the ecosystem's long-term prominence. The PC's development built upon IBM's earlier work with portable computing systems dating back to the 1970s, including the 5100 Portable Computer.
