The PowerBook 160 is a portable computer that was released by Apple Computer along with the PowerBook 145 and PowerBook 180 in October 1992. At the time, it constituted the mid-range model replacing the previous PowerBook 140 in processing power. Its case design is the same as that of the PowerBook 180, but it shipped with the less powerful 25 MHz Motorola 68030 CPU and no FPU, identically to the low-end 145. However, the PowerBook 160 came with a 10 in (diagonal) passive matrix LCD screen, which for the first time was capable of displaying 4-bit grayscale. The 160 and the 180, were the first PowerBooks to add an external color video port like the Macintosh Portable before it, as well as increasing the maximum RAM to 14 MB. Both PowerBooks introduced a new power saving feature which allowed their processors to run at a slower 16 MHz rate, the same speed as the original 140. The PowerBook 160 was sold until May 1994.
