Apple PowerBook 550c Specs

All PowerBook Models | All 1995 Models | Dynamically Compare This Mac to Others


Apple PowerBook 550cThe Apple Macintosh PowerBook 550c -- sold only in Japan -- features a 33 MHz 68040 processor, 8 MB of RAM, and a 500 MB hard drive in a sleek portable case with a 10.4" color active-matrix display.

The PowerBook 500 series introduced the "trackpad" -- where the cursor followed the movement of your finger on a "pad" rather than a plastic ball. The trackpad was a revolutionary input device and has been used since in the vast majority of modern notebooks. The PowerBook 500 series also introduced dual swappable "bays" that could be used to hold either one battery and a PCMCIA adapter or dual batteries to extend runtime.
