There are several kinds of Duo Docks of two main types: The full docks, such as the Apple Duo Dock, take the Duo inside much like a tape into a VCR; full docks provide ADB for keyboard and mouse, video, floppy, SCSI chain, two NuBus card slots, and two serial ports.
Apple’s PowerBook Duo notebooks were very lightweight and very portable, but they are very limited in connectivity unless you can acquire a Duo Dock. The Duo 201, 230, and 280c can all be overclocked. If other Duos can be overclocked, we have not found reports.
My first Mac was an old PowerBook Duo 2300 I got as a birthday gift about four years ago. That’s all it took to get me hooked.
In October 1992, Apple introduced two updated PowerBooks, a new PowerBook Duo series, and the last members of the Macintosh II family. You couldn’t ask for a greater contrast.
2007 – With all the rumors and speculation about a new subcompact MacBook Pro, which some have even suggested might be called the MacBook Pro Duo (I’m exceedingly doubtful about that), I thought it would be timely to take a retrospective look at the original subcompact Mac notebooks (aside from the PowerBook 100, which was […]
1999 – I just purchased a PowerBook Duo 270c from a friend of mine for $100. I am able to network it with my newer computer, but I would like to get this PowerBook online on its own. What kind of modem should I purchase? I also need an external floppy drive.
The PowerBook Duo 2300c was Apple’s only PowerBook Duo based on a PowerPC CPU. To make the 2300c compatible with Duo Docks for earlier models, the 100 MHz 64-bit PowerPC 603e CPU was used on a 33 MHz 32-bit bus, which seriously compromised performance.
Apple upped the ante by moving from the 68030 to the 68LC040 processor on the Duo 280 and 280c in May 1994. (The 68LC040 is a low power version of the 68040 with the internal FPU disabled.) Other than the CPU, this is essentially a Duo 270c.

Introduce in October 1993, the Duo 270c added an active matrix 640 x 480 pixel 256-color screen to the Duo 230. With the improved battery, this color Duo could still run for two hours per charge.
Introduced in October 1993, the PowerBook Duo 250 added an active matrix screen to the Duo mix.
Apple addressed some little things with System 7.1, introduced in 1992. The biggest innovation was putting a Fonts folder inside the System Folder. An entire generation of Mac users has now grown up never having had to move fonts to or from the System file using Font/DA Mover.
Along with the 25 MHz PowerBook Duo 210, the Duo 230 was the first dockable Mac. By eliminating the internal floppy drive (as with PowerBook 100) along with other size and weight saving measures, Apple got this one down to 4.2 pounds.
