The Apple Macintosh PowerBook 180 featured a 33 MHz 68030 processor, 4 MB of RAM, either an 80 MB or 120 MB hard drive, and an internal 1.44 MB floppy drive. The screen was a 9.8-inch grayscale active-matrix display.
The PowerBook 180 supported 4-bit grayscale on the the built-in display, and it allowed 8-bit color when plugged into an external monitor.
Because the laptop supported an external color screen, included a fast processor for the time, and supported a 120 MB hard drive, this PowerBook was the first Macintosh laptop that could replace a desktop with no compromises. In fact, the PowerBook 180 was equivalent in performance to the Macintosh LC III+, also available at the time.
