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.
Macintosh IIx The Macintosh IIx was introduced by Apple Computer in 1988 as an incremental update of the original Macintosh II model. It replaced the 16 MHz Motorola 68020 CPU and 68881 FPU of the II with a 68030 CPU and 68882 FPU running at the same clock speed; and the 800 KB floppy drive with the 1.44 MB SuperDrive (the first Mac to have this feature). The initial price of the IIx was US$ or US$ for a version with the 40 MB hard drive.
