PowerBook 140

PowerBook 140 is a notebook computer introduced by Apple in October 1991 as part of the first generation of the PowerBook line. It was positioned as the mid-range model between the low-end PowerBook 100 and high-end PowerBook 170. Like the PowerBook 170, it included an internal floppy disk drive, unlike the PowerBook 100. However, like the PowerBook 100, it used a passive-matrix LCD, a 16 MHz processor, and 2 MB of onboard RAM, compared with the PowerBook 170's active-matrix display, 25 MHz processor, and 4 MB of RAM. In 1992, the PowerBook 160 assumed the 140's role as Apple's mid-range notebook. The PowerBook 145, a revision of the PowerBook 140 with a faster 25 MHz processor and 4 MB of RAM, became Apple's entry-level notebook. In 1993, it was succeeded by the lower-priced PowerBook 145B.
