What was the introduction date of this line of Macintosh portable computers, introduced in conjunction with the MagSafe?
MagSafe MagSafe is a series of proprietary magnetically attached power connectors, originally introduced by Apple Inc. on January 10, 2006, in conjunction with the MacBook Pro at the Macworld Expo in San Francisco, California. The connector is held in place magnetically so that if it is tugged — for example, by someone tripping over the cord — it will pull out of the socket without damaging the connector or the computer power socket, and without pulling the computer off the surface on which it is located.
PowerBook 180 The PowerBook 180 is a portable computer released by Apple Computer, Inc. along with the PowerBook 160 in October 1992. At the time, it constituted the new top-of-the-range model replacing the previous PowerBook 170. Its case design and features are the same as that of the 170, but it shipped with the more powerful 33 MHz Motorola 68030 CPU and Motorola 68882 FPU. Along with the 160, it introduced a new power saving feature which allowed the processor to run at a slower 16 MHz rate, the same speed as the original 140.
