The Apple Macintosh PowerBook 160 features a 25 MHz 68030 processor, 4 MB of RAM, either a 40 MB, 80, or 120 MB hard drive, and an internal 1.44 MB floppy drive in a compact portable case with a 9.8" grayscale passive-matrix display.

Most notably, although the built-in display on the PowerBook 160 only supports 4-bit grayscale, it supports 8-bit color on an external monitor and was the first PowerBook to offer such capability.
