PowerBook 140

The Macintosh PowerBook 140, introduced in 1991 (along with the PowerBook 100 and PowerBook 170), was the mid-range PowerBook.
As the mid-range laptop in its day, the PowerBook 140 was faster, and came with a larger display.
The PowerBook 140, unlike the PowerBook 100 and the Macintosh Portable, uses a NiCad battery.
Weighing in at 6.8 pounds, the PowerBook 140 zips along at 16 MHz on a Motorola 68030 chip and has 2 MB of RAM (expandable to 8 MB).
