iMac G3

The original "Bondi Blue" iMac G3, released in 1998.

The iMac G3 was the first model of the iMac line of personal computers made by Apple Computer. The iMac G3, based on the Columbus architecture is an all-in-one personal computer, encompassing both the monitor and the computer in a single enclosure. Originally released in striking "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 streamlined 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 started shipping it on August 15, 1998.

Aesthetically, the iMac was dramatically different from any other mainstream computer ever released. 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.

The iMac was the first computer to offer USB ports as standard, including the connector for its new keyboard and mouse, thus abandoning previous Macintosh peripheral connections, such as the ADB, SCSI and GeoPort serial ports.

A radical step was to abandon the 3½-inch floppy 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's move was considered ahead of its time and was hotly debated. At the iMac's introduction, third-party manufacturers offered inexpensive external USB diskette drives.

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 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 in later versions so that users could distinguish where the button was. Eventually, a new oblong optical mouse, known as the Apple Pro Mouse (later "Apple Mouse"), replaced the round mouse across all of Apple's hardware offerings.

Technical

Internally, the iMac was a combination of the Macintosh NC project and CHRP.^{[citation needed]} 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; this was removed from later iMacs. According to an article in the German computer magazine c't, the socket can be retrofitted on revision C iMacs.^{[citation needed]} The hard drive in the iMac G3 was a Quantum Fireball.

Updates

iMac G3 "flavours" which replaced Bondi Blue.

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.

Successors

With the introduction of the LCD-based iMac G4, the older CRT model was retroactively renamed the iMac G3 and kept in production for the education market until being replaced by eMac.

As Apple continued to release newer versions of its computers, the term iMac continued to be used to refer to all-in-one models of its consumer desktop lines.

Timeline of iMac models

Legal action

Apple protected the iMac design with legal action against other computer manufacturers who made imitations, such as the eMachines eOne. Some manufacturers added translucent plastics to existing designs, following the trend started by Apple. 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
