The iMac G3 was the first model of the iMac line of personal computers made by Apple Inc. (formerly Apple Computer, Inc.), and the originator of the Legacy-free PC market category. Like the first Macs, the iMac G3 is an all-in-one personal computer, encompassing both the monitor and the system unit in a single enclosure. Originally released in bondi blue and later a range of other brightly colored, translucent plastic casings, the iMac shipped with a keyboard and mouse in matching tints.

History

Steve Jobs reduced the company's large and confusing product lines immediately after becoming Apple's interim CEO in 1997; toward the end of the year, Apple trimmed its line of desktop Macs down to the beige Power Macintosh G3 series, which included the iMac's immediate predecessor, the G3 All-In-One, which featured nearly identical specifications and was sold only to the educational market. Having discontinued the consumer-targeted Performa series, Apple needed a replacement for the Performa's price point. The company announced the iMac on May 6, 1998 and began shipping the iMac G3 on August 15, 1998. The iMac was dramatically different from any previous mainstream computer. It was made of translucent "Bondi Blue"-colored plastic, and was egg-shaped around a 15-inch (38 cm) CRT. There was a handle, and the computer interfaces were hidden behind a door that opened on the right-hand side of the machine. Dual headphone jacks in the front complemented the built-in stereo speakers. Jonathan Ive, currently Vice President of Industrial Design at Apple, is credited with the industrial design.

A radical step was to abandon the 3½-inch diskette drive (which had been present in every Mac since the first one in 1984). Apple argued that recordable CDs, the internet, and office networks were quickly making diskettes obsolete. Apple had initially announced the internal modem in the iMac would operate at only 33.6 kbit/s rather than the new 56k speed, but was forced by consumer pressure to adopt the faster standard. Apple's omissions generated controversy. At the time of iMac's introduction, third-party manufacturers offered inexpensive external USB diskette drives, often in translucent blue plastic to match the iMac's enclosure.

The keyboard and mouse were redesigned for the iMac with translucent plastics and a Bondi Blue trim (Apple USB Keyboard and Apple USB Mouse). The keyboard was smaller than Apple's previous keyboards, with white letters on black keys, both features that attracted debate. The mouse was mechanical, of a round, "hockey puck" design which was instantly derided as being unnecessarily difficult for users with larger hands. Apple continued shipping the round mouse, adding a divot to the button in later versions so that users could distinguish proper orientation. Eventually, a new oblong optical mouse, known as the Apple Mouse (formerly "Apple Pro Mouse"), replaced the round mouse across all of Apple's hardware offerings.

Technical

Internally, the iMac was a combination of the MacNC project and Common Hardware Reference Platform (CHRP). Although the promise of CHRP has never been fully realized, the work that Apple had done on CHRP significantly helped in the designing of the iMac. The original iMac had a 233 MHz PowerPC G3 (PowerPC 750) chip, with 512 KB L2 cache running at 116.6 MHz, which also ran in Apple's high-end Power Macintosh line at the time, though at higher speeds, with more expensive models shipping with 1 MB L2 cache. It sold for US$1,299, and had a 4 GB hard drive, 32 MB RAM, 2 MB video RAM, and shipped with Mac OS 8.1, which was soon upgraded to Mac OS 8.5. Parts such as the front-mounted IrDA port and the tray-loading CD-ROM drive were borrowed from the Apple laptops. Although the iMac did not officially have an expansion slot, the first versions had a slot dubbed the "mezzanine slot". It was only for internal use by Apple, although a few third-party expansion cards were released for it, such as a Voodoo II video card upgrade from 3dfx and SCSI/SCSI-TV tuner cards (iProRAID and iProRAID TV) from the German company Formac. The mezzanine slot was removed from later iMacs, though according to an article in the German computer magazine c't, the socket can be retrofitted on revision C iMacs. The hard drive in the iMac G3 was a Quantum Fireball.

Updates

The iMac line was continually updated after initial release. Aside from increasing processor speed, video RAM, and hard-disk capacity, Apple replaced Bondi blue with new colors—initially blueberry, strawberry, tangerine, grape, and lime; later other colors, such as graphite, ruby, sage, snow, and indigo, and the "Blue Dalmatian" and "Flower Power" patterns. A later hardware update created a sleeker design. This second-generation iMac featured a slot-loading optical drive, FireWire, "fanless" operation (through free convection cooling), and the option of AirPort wireless networking. Apple continued to sell this line of iMacs until March 2003, mainly to customers who wanted the ability to run the older Mac OS 9 operating system.

USB and FireWire support, and support for dial-up, Ethernet, and wireless networking (via 802.11b and Bluetooth) soon became standard across Apple's entire product line. In particular, the high-speed interface, FireWire, corrected the deficiencies of the earlier iMacs.

The iMac CRT model, now targeted at the education market, was renamed the iMac G3, and kept in production alongside the iMac G4 successor until the eMac was released.

As Apple continued to release new versions of its computers, the term iMac continued to be used to refer to machines in its consumer desktop line.

In popular culture

The iMac G3 was prominent in early 2000s pop culture. It was featured on many different TV shows, including Daria, King of the Hill, Ned's Declassified School Survival Guide, George Lopez, My Family, Malcolm in the Middle, Queer as Folk, Lizzie McGuire, The Simpsons, My Wife and Kids, American Dad!, and Arthur. iMacs were also featured in the films Zoolander, Max Keeble's Big Move, Scooby-Doo! The Mystery Begins, and Freaky Friday, the syndicated comic strip FoxTrot, the flash series Homestar Runner, and the site BrainPOP.

Legal action

Apple protected the iMac design with legal action against computer makers who made imitations, such as eMachines’ eOne. Some manufacturers added translucent plastics to existing designs after the iMac, following the trend started in 1997 by Dyson. In 1999, Apple obtained the registered domain name appleimac.com from Abdul Traya, after legal intervention. The website now automatically redirects to Apple Inc.'s website
