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of the 140, the 145 was actually the replacement for the PowerBook 100 as the low-end model, with the 140 having been superseded by the new mid-level PowerBook 160.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.
