iMac Late 1999 Datasheet

In the ever-evolving landscape of personal computers, one device emerged in 1999 that not only captured the essence of innovation but also left an indelible mark on the industry. The Apple iMac Late 1999, affectionately known as the iMac with Slot Loading Drive, stands as a testament to the convergence of cutting-edge technology and sleek design.

The roots of the iMac Late 1999 can be traced back to the immediate aftermath of the first iMac shipment. The development of the “Kihei” model marked an evolutionary step for Apple, leveraging the success of its predecessor. Introduced to the market on October 5, 1999, this marvel required Mac OS 8.5 or later to unleash its full potential.

Distinguished by its slot-loading CD-ROM and DVD-ROM drives, a 100 MHz system bus, RAGE 128 graphics on a 2x AGP bus, a Harmon Kardon sound system with an optional subwoofer, and compatibility with Apple’s 802.11b AirPort Card (adapter required), the iMac Late 1999 was a technological spectacle. The new case design, reminiscent of the classic Macintosh Plus and Volkswagen Beetle, embraced air cooling, eliminating the need for a cooling fan. This innovation, coupled with a more compact and lighter build, marked a departure from the tray-loading iMacs.

At its core, the iMac Late 1999 boasted a formidable 350 MHz PowerPC 750 G3 processor, a 15-inch CRT display, 64 MB of RAM, a 6 GB hard drive, a 24x CD-ROM slot-loading drive, and 8 MB ATI Rage 128 VR graphics. This formidable combination of features positioned the iMac as an attractive option for consumers seeking a potent and budget-friendly computing solution.

Compared to its predecessor, the iMac Early 1999 series, the Late 1999 version showcased significant improvements. The slot-loading CD-ROM drive, a faster processor, an enhanced system bus, increased default RAM, a speedier Ultra ATA hard drive, an upgraded video processor with more VRAM, a superior sound system, and optional AirPort (802.11b) wireless card support solidified its status as a technological powerhouse.

As with all technological marvels, the iMac with Slot Loading Drive had its moment in the sun. On July 19, 2000, it was officially discontinued, making way for the iMac Mid 2000. Despite its departure from the market, the iMac Late 1999 continued to hold its ground, securing a permanent place in the annals of technology history.

Even 24 years after its initial release, the iMac Late 1999 remains a symbol of innovation and a significant piece of technological heritage. Its sleek design and groundbreaking features have paved the way for the evolution of Apple products, leaving an enduring legacy that resonates with enthusiasts and tech aficionados alike.

In retrospect, the iMac Late 1999 was more than just a computer; it was a harbinger of change and a pioneer in personal computing. Its impact reverberates through the corridors of time, influencing subsequent generations of Apple products.

As we navigate the digital landscape of the present, we can’t help but acknowledge the role played by this iconic device in shaping the technological marvels we enjoy today. The iMac Late 1999 stands tall as a timeless beacon of innovation, reminding us that the pursuit of excellence is a journey that transcends the constraints of time.
