iMac (Bondi Blue)

Introduced: August 1998
Terminated: January 1999


The original iMac was an all-in-one shipped in an entirely new “Bondi Blue” translucent plastic case.  It ran the G3 PowerPC 750 processor at 233Mhz and had 4Gb hard drive.  It had a tray loading CD-ROM, a USB keyboard and a USB mouse.  It had a maximum RAM of 256Mb and an ATI Rage IIc graphics card.  The built-in monitor was a 15-inch shadow mask CRT with a 13.8” viewable area.  There was one mezzanine expansion slot, analog audio input/output jacks, a built-in microphone and built-in speakers.


The iMac represented a new vision for Macintosh computers.  It was posited as a computer for the new millennium.  The “i” indicated the computer’s compatibility with the internet, which was expanding at an exponential rate. The new case was sleek and modern, with the familiar handle that had been a feature on many early Macintoshes.

The iMac was aimed at a low-budget market, with the original costing $1,299.  There was considerable attention given to it from the press and from marketing.  The unique new design made it easily recognizable, giving Apple new brand awareness.  Ease-of-use was much touted by Apple and consumers found that it lived up to that promise, affording the ability to set up and connect to the Internet in two steps. 

There were initially detractors who did not approve of Apple’s changes to hardware and their changing priorities, the original G3 iMac launched a hugely successful commercial line that is still in production.  Tapping into the Internet boom and highlighting their user-friendly interface became lasting hallmarks of the iMac line.

  • I wonder if this machine would have been able to run an analytics software comparison. iMac was very advanced at that time. I guess that iMac was always ahead when it came to technology, but very behind when it comes to compatibility with other software.
