Macintosh Portable

Introduced: September 1989
Terminated: October 1991

Description

Apple’s first foray into portable computers was the Macintosh Portable.  It was similar to the Macintosh SE.  Using a low energy version of the Motorola 68000, it ran at 16MHz.  It had 1MB of RAM that was expandable to 9MB.

The screen was a black and white active matrix display; it flipped down, covering the keyboard, when the computer was not in use.  Mouse functions were handled by a trackball to the right side of the keyboard.  It had a 3.5” floppy drive, an optional internal hard drive and an internal modem.

The Macintosh Portable weighed 15.8 pounds, meaning that it was not very easy to carry around.  The travel battery was good for up to ten hours.  The battery charged through power supply, but the computer could not run off of AC power.

History

Though it was widely liked by reviewers, the Macintosh Portable was not a commercial success.  At $6,500 it was expensive and not without its problems.  The clunky build and poor readability depending on the lighting were just some of drawbacks that limited sales.

Although it was not successful, the Macintosh Portable was a major step in the newly emerging world of portable computers.  If nothing else, the design problems helped to show what to avoid in the future.

Timeline

After the Macintosh Portable was released in 1989, problems with readability lead the release of a Macintosh Portable with backlighting in 1991.  The backlighting, however, caused the battery life to be cut in half.  It was discontinued later that year.

  • I like it’s design very much and I think it looks great in black and white, but I think this is a little expensive and I don’t know if I can afford one like this. Cazare Rucar ieftina
