iMac G3/233 Processor Upgrade And Discussion
Page - Performance
Of Latest G3 Processor Upgrades
Introduced in the late summer of 1998, the
original iMac was an instant success, selling over 300,000
units in its first few months of availability. Not only was
it snatched up by diehard Mac users, but Wintel converts and
first time computer users flocked in droves to to get their
hands on an iMac. The press, other than a few naysayers, fell
all over themselves in praise of this innovative product from
Apple. The computer was exceptionally easy to set up and connect
to the Internet. Reviewers praised both the design and low
cost of the machine calling the iMac a great value
In large part it was the iMac that revived
Apples fortunes, from what had been a near death experience
for the company.
The computer was completely aimed at the
consumer and education markets. It has no PCI expansion slots,
no free drive bays and limited graphics upgradability. There
is also no SCSI port or other high-speed transfer protocol.
The machine uses hot-swappable USB ports (of which there are
two on the machine) for connecting keyboard, mice or other
external devices. This use of USB was a first for a Mac and
heralded an explosion of USB capable devices.
The original iMac sports a G3/233 processor with 512K of
backside cache. It has 2MB of VRAM giving you thousands of colors
at 1,024 x 768 pixels. You can add an additional 4MB allowing
you to have millions of colors at the highest resolutions. It
is capable of 2D & 3D acceleration courtesy of a ATI Rage
IIc graphics chip.

The machine came with an anemic 32MB of Ram installed, which could
be expanded to 128MB at the time of its release (see "Facts
At A Glance" notes). It had a fast 4GB hard
drive but came without a floppy drive. The lack of a floppy drive
generated a lot of criticism but the market quickly adjusted and
provided other methods for getting data in and out of the iMac.
The CD-ROM drive is 24X and is rather noisy in operation. It is
the same CD drive found in the PowerBooks of the time, and does
not have a powered drawer. It is kind of fragile for school use.
Some complaints were raised by traditionalist
about the compact keyboard and the non-standard round mouse. However
many new users liked both.
On the front of the machine is a infrared port,
from which you can beam information to/from other infrared capable
devices, such as PowerBooks, digital cameras etc. The machine
has a built-in 56K modem and on-board 10/100 Base-T Ethernet.
In a few short months Apple came out with a revision
"B" of the iMac. Bowing to the complaints of gamers,
this revision had 6MB of VRAM and a better graphics accelerator
- the ATI Rage Pro Turbo - but otherwise remained unchanged.
