Macintosh PowerBook G3

Introduced: November 1997
Terminated: May 1998


Running the new G3 PowerPC 750 processor at 250Mhz, the PowerBook G3 had a 5Gb hard drive.  It had a 1.4Mb floppy drive and a 20x CD-ROM.  It had a trackpad and a full size keyboard and weighed 7.5lbs.  There was 32Mb of logicboard RAM that was expandable to 160Mb.  It had a 12.1” active matrix LCD screen with an 800 x 600 resolution. 


The first PowerBook to use the G3 processor, it was similar to the PowerBook 3400 but more than two times faster.  It also had improved graphics abilities that allowed the screen to refresh much faster than any previous models.

The PowerBook G3 is the only G3 model that was not compatible with Mac OS X, which would be released in the future.

    Credit to Apple for sticking it out and bringing out new devices in the market to make it (market) more competitive. - Guy Riordan
