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.
