The PowerBook 180 was the first portable Mac with a 4-bit active matrix display. With a 33 MHz CPU and improved screen, it replaced the PowerBook 170 and was in very high demand through its life. Like the PowerBook 160, the 180 has a video out port supporting an external 13-inch to 16-inch monitor. With the PowerBook 160, it was the first PowerBook to support more than 8 MB of RAM.
 
The PowerBook 180 reintroduced SCSI Disk Mode to the PowerBook line, a feature previously found only on the PowerBook 100.
 
As with all early PowerBooks, when buying used be sure it has all the memory you need (new PowerBook RAM is getting more difficult to locate, especially at reasonable prices).
The PowerBook 180 has a 14 MB memory ceiling, although you can go beyond that by using Virtual Memory (slow and free) or RAM Doubler (faster, not free, and discontinued). Another option is RAM Charger 8.1, which offers better memory management than the Mac OS.
