iMac G3 333 Hz Revision D 1999

The iMac G3 333 Hz Revision D is identical to its predecessor save for the processor speed upgraded to 333 Hz. It had lost the mezzanine slot and the IrDA port. So on a bright side, the price was reduced. The design remained the same but five more “fruit” colors were added: Blueberry, Strawberry, Grape, Lime, Tangerine.

  • The speakers are manufactured by the third party Harmon-Cardon.
  • The iMac G3 design is protected by copyright law, so it’s unique. It supports the external hard drive via FireWire, e.g. an iBook and the internal hard-drive up to 128 GB of storage. This makes the iMac G3 a stylish choice for a home web-surfing center or server. That is if you’re fine with the old shimmering monitor.
  • iMac G3 is one of the most upgradable Apple products. One can enhance the RAM and even replace the hard drive with the solid state drive. It will boost the performance. Even now iMac G3 is OK to surf Web, to write some documents and watch non-HD movies. It can also stand in as a home server. Of course, all these things demand some expertize at least at an advanced user level. But it shows how reliable first iMacs were and are. I doubt you can make any of IMB based desktop from the late nineties work even with SSD installed.
  • iMac G3 with 233 MHz clock speed undergone two revisions: A and B, featuring the Power PC processors models and the upper limit of the RAM supported. The video card across the generation was on ATI chip.
  • Tray-loaded iMacs G3 arrived in 1998 and the slot-loaded – in 1999. The slot-loaded iMac G3 also sports FireWire port, AirPort for Wi-Fi connection and the top hardware specifications of the family: up to 60 GB hard drive, up to 256 MB RAM and up to 700 MHz clock speed. This one iMac G3 also sports the most outrageous colors of the Apple gamut: Flower Power and Dalmatian Blue.
  • Yes, for general public that couldn’t tell a processor from a can of beans, iMac G3 revisions were marked with colors. iMac G3 was the first ever desktop (and the only one to our knowledge) that went wild with colors. Bondi Blue was succeeded with so called ‘fruit colors’ – Blueberry, Grape, Strawberry, Tangerine and Lime. Then with first tray-loaded iMacs came more serene Indigo, Snow and Graphite for those who might like less vibrant hues in their surroundings (those were models of 2000). And then Power Flower and Blue Dalmatian brought up the rear. Malicious rumor has it, they ran out of colors and had to invent something extraordinary to invite the public to buy. In a way, it was an ingenious move, since these iMacs will never be forgotten and were voted as the ugliest and the weirdest iMacs of all times.
  • iMac G3 ran on Mac OS 8 based on HFS+ file system, also referred to as Mac OS Standard, HFS Standard or Sequoia. The latest representatives of the family can be upgraded to Mac OS X 10.4.11 “Tiger” and Mac OS 9.2.2.
