Apple PowerBook Duo 210

Apple PowerBook Duo 210 was introduced in 19 October 1992 as the first ultra-compact PowerBook Duo, designed to gain desktop ports, drives and expansion when inserted into a Duo Dock. It used a Motorola 68030 at 25 MHz with 4MB standard; expandable to 24MB. Motorised Duo Dock could accept the notebook and expose monitor, floppy and NuBus expansion.

The docking concept offered a genuinely small travelling computer without forcing office users to give up a full desktop environment.

Notable Features

• Motorised Duo Dock could accept the notebook and expose monitor, floppy and NuBus expansion.
• No internal floppy drive reduced weight and thickness.
• Compact display and keyboard prioritised portability.

Historical Significance

• The docking concept offered a genuinely small travelling computer without forcing office users to give up a full desktop environment.
• Its place in the range reflects Apple's progression from the original compact Macintosh toward broader professional, educational and portable markets.

Collector’s Notes

• Dock mechanism condition, display cabling and original power adapter are important
• Original keyboards, mice, storage devices and model-specific accessories help document a complete period configuration.
