Of Latest G3 Processor Upgrades
The iMac was the first complete machine that
was the result of the "2nd Coming of Jobs" era. Its unique
all-in-one futuristic design, speedy processor, low price
and excellent marketing propelled it to become one of the
best selling computers of its time. The revision C version
of the iMac was released at the January 1999 Macworld in San
Francisco, a short 6 months after the initial release of the
original iMac. As of the release of version C, Apple had sold
over 800,000 units of previous iMac versions. According to
Apple 40% of purchasers were first time computer purchasers
and Wintel converts.
The revision C iMac has a few modest technological
improvements over the previous revision. There is a small
processor performance boost (from 233Mhz to 266Mhz), a larger
hard drive (6GB instead of 4) and the machine came with OS
8.5.1 installed which fixed some bugs in the original release
of 8.5. The biggest change with revision C was in its looks.
The iMac came in 5 Lifesaver colors; strawberry, lime, tangerine,
grape and blueberry. In addition Apple dropped the price on
the revision C iMacs 8% from the price for the previous version.
Apple showed, with the iMac, that it had really
got on the ball again in marketing and generating interest
in its products. The changes to the C version are really rather
modest in terms of technology, but when combined with the
cosmetic changes, the C versions made quite a big splash.
Apple's efforts showed just the type of care and nurturing
of its product line that had been woefully missing in previous
The machine sports a G3/266 processor with 512K of backside
cache running at 133MHZ. It 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"). 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.

As with previous iMacs there is no floppy drive
or high-speed SCSI port for connecting external drives. Instead
the iMac has two 12Mbps hot-pluggable USB ports and built in high
speed 10/100BASE-T Ethernet. Also included, was an internal 56Kbps
Other changes that occurred with this revision
of the iMac, was the removal of the proprietary mezzanine slot
and, alas, the infrared port.
Geared for the consumer , school and business market
the machine is capable of very little upgradability and is more
appropriate for general computer use. The machine came with a
substantial software bundle.
Some complaints were raised by traditionalist
about the compact keyboard and the non-standard round mouse. However
many new users liked both.
