PowerBook 145

The PowerBook 145, manufactured by Apple Computer, was a speed-bumped successor to the PowerBook 140 that was released on August 3, 1992.

Specifications
The processor speed was increased from 16 to 25 MHz. The standard hard drive was upgraded from 20 to 40 MB. The 145 also introduced a new feature for the battery-conscious: users would be able to set the 145 to sleep or completely shut down whenever the clamshell unit was closed.

History
Though a direct descendant of the 140, the 145 was actually the replacement for the PowerBook 100 as the low-end model, with the 140 having been superseded by the new mid-level PowerBook 160. It was replaced by the PowerBook 145B in June 1993. The codename for this model is: Colt 45.
