The PowerBook 140 is a notebook computer that was released in the first line of PowerBooks. It was the mid-range PowerBook, between the low-end 100 and the high-end 170. As with the PowerBook 170, it featured an internal floppy drive, unlike the 100. Codenames for this model are: Tim Lite, Tim LC, Replacements, and Leary. In 1992, it was replaced by the PowerBook 145, which was essentially a speed bump, though the PowerBook 160 essentially superseded it as the new mid-line model.
