IBM 5140 "Convertible"

 IBM's first laptop computer was called the PC Convertible because with a few add-on modules, it could become a primary desktop machine. IBM's entry into laptop computers legitimized the fledgling IBM-compatible laptop market that had largely been pioneered by Toshiba. It could run on battery or AC Adapter. Strangely, the PC Convertible's styling is identical to the IBM PS/2 lineup, although the PS/2s were not introduced for another year or more.
