power book 140
The PowerBook 140 was - along with the PowerBook 100 and PowerBook 170 - launched on the market in the fall of 1991. It was equipped with a Motorola 68030 processor, 2 MB of operating memory and an HDD with a capacity of 20, 40 or 80 GB. In terms of design, it was practically the same as its siblings. Compared to the first mentioned model, it had a slightly larger display, slightly larger dimensions and an internal 3,5-inch floppy disk drive (the PowerBook 100 had to make do with an external one). It was intended as a replacement for Apple's first portable computer, the Macintosh Portable. Unlike it, it had an LCD display with a passive matrix, which made it significantly cheaper ($3 vs. $199). In 7 and 300 Apple launched slightly more powerful PowerBook 145 and 145B models.
