History: Introduced in October 1991, The PowerBook 140 was a 68030 (16 MHz) counterpart to the PowerBook 100. It also included an internal floppy drive, a feature that the 100 lacked. Despite the problems inherent in the passive matrix screen, the PowerBook 140 was a remarkably viable machine. It sold for $2,000 U.S., and was discontinued in August 1992, when it was replaced by the PowerBook 145.
