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 with no FPU, identical to the low-end 145. However, the PowerBook 160 came with a 10-inch (diagonal) passive matrix LCD screen, which for the first time was capable of displaying 4-bit grayscale. Like the Macintosh Portable before it, the 160 and the 180, were the first PowerBooks to add an external color video port, as well as increasing the maximum RAM to 14MB. 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. It was sold until May 1994.
The 165 added a 33MHz processor and larger standard hard drive. Along with the PowerBook 145B, this would be the last of the true 100 series PowerBooks and the last Apple laptop to include two serial (printer & modem) ports. It's entry level descendant, the PowerBook 150, would continue to sell for another year and though it used the 140 case design, its internals were actually based on the PowerBook Duo and PowerBook 190, a 100 series PowerBook in name only as it used the PowerBook 5300's motherboard and case as well.
The 165c (pictured)was identical to the 165, except that it included a 68882 FPU and had a passive matrix color LCD capable of displaying 256 colors. As a result of the thicker color display, the exterior case lid was redesigned, more closely resembling that used on the PowerBook Duo series. The PowerBook 180c used the same case modification.
