Macintosh PowerBook 140

The PowerBook 140 was released in 1991 and is the first PowerBook to be designed by Apple Computer, as the Macintosh PowerBook 100 is actually a Sony design. It is the mid-level PowerBook between the 100 model and the Macintosh PowerBook 170.

General Information

Introduced in October 1991, the PowerBook 140 was a 68030 (16 MHz) counterpart to the Macintosh 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 and was discontinued in August 1992, when it was replaced by the Macintosh PowerBook 145.

Codenames: Tim LC, Tim Lite, Leary. Originally shipped with system software 7.0.1.

CPU

The PowerBook 140 uses the Motorola 68030 processor clocked at 16MHz. There is also a lack of math co-processor.

Memory

There is 2MB RAM onboard and the system can be expanded to 8MB total.
