laptop by Apple

The PowerBook 180 was the first portable Mac with a 4-bit (16-shade) active matrix display. With a 33 MHz CPU and improved screen, it replaced the 25 MHz PowerBook 170 and was in very high demand through its six-month life.

Like the PowerBook 160 , the 180 has a video out port supporting an external 13″ to 16″ monitor. With the 160, it was the first PowerBook to support an external monitor (using Apple’s proprietary VID-14 connector with an adapter) and the first PowerBook to support more than 8 MB of RAM.

The 180 reintroduced SCSI Disk Mode to the PowerBook line, a feature previously found only on the PowerBook 100 .
