Features
Intended as a replacement for the Portable, the 140 series was identical to the 170, though it compromised a number of the high-end model's features to make it a more affordable mid-range option. The most apparent difference was that the 140 used a cheaper, 10 in (25 cm) diagonal
The 140 was introduced with
Design
Though released at the same time as the PowerBook 170 and PowerBook 100, both the 140 and 170 were designed entirely by Apple, while the 100 was miniaturized by Sony from the full-sized Macintosh Portable. As a result, the 140 represents the very first notebook computer created by Apple, with the 100 actually representing the first design improvements, though its internal architecture is the oldest in the series. 140 was designed by Gavin Ivester of the internal Apple Industrial Design Group.
PowerBook 145
The PowerBook 145 was a speed-bumped 140, increasing the processor speed from 16 MHz to 25 MHz. The standard hard drive was upgraded from 20 MB to 40 MB. The 145 also introduced a new feature for the battery-conscious: users would be able to configure the 145 to sleep or completely shut down whenever the clamshell unit was closed. Though a direct descendant of the 140, the 145 was actually the replacement for the PowerBook 100 as the low-end model, the 140 having been superseded by the new mid-level PowerBook 160.
It was replaced by the PowerBook 145B in June 1993. The only codename for this model is: Colt 45.
PowerBook 145B
The PowerBook 145B was the same as the PowerBook 145 that came before it, but with a lower price and additional 2 MB of RAM soldered to the motherboard. The only codename for this model is Pikes Peak.
Unlike previous Mac models but like the
The 145 was superseded by the PowerBook 150 as the next low-end PowerBook.
