Identification and Background ¶
The PowerBook 100 Series was the released in October 1991. It was the very first generation of PowerBook laptops.
These machines caused a stir in the industry with their compact dark grey cases, use of a trackball, and the clever positioning of the keyboard which left room for palmrests on either side of the pointing device. Portable computers at the time tended to have the keyboard forward towards the user, with empty space behind it, so this was a surprising innovation and set the standard layout all future notebook computers would follow.
The PowerBook 140 and 170 were the original PowerBook designs, while the PowerBook 100 was the result of Apple having sent the schematics of the Mac Portable to Sony, who miniaturized the components. Hence the PowerBook 100's design does not match those of the rest of the series, as it was actually designed after the 140 & 170 and further benefited from improvements learned during their development. The PowerBook 100, however, did not sell well until Apple dropped the price substantially.
