Macintosh PowerBook Duo 210 Datasheet

In 1992, Apple unveiled the Macintosh PowerBook Duo 210, a groundbreaking addition to their Macintosh PowerBook series. While its lifespan was short-lived, this portable notebook left an indelible mark on the world of technology, setting new standards for laptops that followed.

The Macintosh PowerBook Duo 210 was officially launched on October 19, 1992, and quickly garnered attention for its innovative design. Weighing a mere 4.2 pounds, Apple achieved this remarkable lightweight profile by eliminating the internal floppy drive and implementing other size- and weight-saving measures. It was a true pioneer in dockable Macs, making it possible to seamlessly transition from a portable notebook to a desktop Macintosh by connecting it to the dedicated Duo Dock.

Equipped with a 25 MHz Motorola 68030 processor, a 9.1-inch monochrome LCD display, 4 MB of RAM, and an 80 MB hard drive, the Macintosh PowerBook Duo 210 was a capable computing machine for its time. Its 4-bit passive-matrix screen resembled that of the PowerBook 160, which weighed significantly more at 6.8 pounds. Though not as powerful as modern devices, the Duo 210 represented a major leap forward in terms of portability and convenience.

While the Macintosh PowerBook Duo 210 introduced groundbreaking features, it did have a few limitations. Due to its slim form factor, it lacked an internal floppy drive, external hard drive support, SCSI device compatibility, direct connection to an external display, and standalone network capabilities. These functionalities were only available when the notebook was docked into the Duo Dock. Unfortunately, these limitations and the emergence of more advanced models led to the discontinuation of the Macintosh PowerBook Duo 210 on October 21, 1993, after just one year on the market.

Despite its relatively short lifespan, the Macintosh PowerBook Duo 210 remains a significant part of Apple’s history and the evolution of portable computing. Its innovative design and engineering showcased Apple’s commitment to pushing the boundaries of technology. The PB Duo 210 set the stage for future laptops by demonstrating the potential for seamless transitions between portable and desktop experiences. It laid the groundwork for the integration of features we now take for granted in modern laptops.

As we look back at the Macintosh PowerBook Duo 210 on its 31-year anniversary, we recognize its game-changing impact on the world of portable computing. This pioneering notebook showcased Apple’s dedication to innovation and design excellence while setting new standards for future laptops. Though no longer in production, the Macintosh PowerBook Duo 210 will forever be remembered as a historical relic that shaped the trajectory of portable computing, leaving an enduring legacy within Apple’s rich technological heritage.
