Apple Macintosh PowerBook 180C
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 PB 170 and was in very high demand through its life. Like the PB 160, the 180 has a video out port supporting an external 13" to 16" monitor. With the PB 160, it was the first PowerBook to support more than 8 MB of RAM.
The PB 180 reintroduced SCSI Disk Mode to the PowerBook line, a feature previously found only on the PB 100.
As with all early PowerBooks, when buying used be sure it has all the memory you need (new PB RAM is getting more difficult to locate, especially at reasonable prices).
The PB 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.
