The PowerBook 170 was the only first generation PowerBook to sport an active matrix screen. With a 25 MHz 68030, it was 2/3 faster than the PowerBook 140. Between the faster CPU, faster screen, and addition of a floating point unit, the 170 was nearly twice as fast as the 140. It was replaced by the popular PowerBook 180 in October 1992.

Apple released two special editions of the PowerBook 170: a multicolored version for the Japan LPGA and a white “10th Anniversary Mac” version in 1994.

As with all early PowerBooks, when buying one be sure it has all the memory you need (new PB RAM is difficult to locate, especially at reasonable prices).

The PB 170 has an 8 MB memory ceiling, although you can go beyond that by using Virtual Memory (slow and free) or RAM Doubler (faster, not free, and now discontinued). Another option is RAM Charger 8.1, which offers better memory management than the Mac OS.
