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.
Here is a shot of the PC Convertible with the serial/parallel module, display module, and printer module attached. The PC Convertible monitor sits in the background on its special stand that allows it to peer over the back of the PC Convertible. |
