PowerBook Duo 270c

The PowerBook Duo 270c was the first color subnotebook from the PowerBook Duo line to be introduced by Apple Computer on October 21, 1993.

Features
The Duo 270c featured a 33 MHz Motorola 68030 processor. It was the first model with an active matrix color display (8.4-inch) which supported 640x480 in 8-bit color, and 640x400 ed in 16-bit color. It is the only Duo model to contain its own built-in Motorola 68882 floating-point unit. The logic board contained 4 MB of RAM which could be upgraded to 32 MB. It also included an improved Type 2 battery.

The Duo 270c was compatible with the Duo Dock II and Plus models. Owners of the original Duo Dock required a top cover upgrade to accommodate the slightly greater thickness of the color display.

The Duo 270c shipped with System 7.1 (with PowerBook Duo Enabler v1.0) and could be upgraded to Mac OS 7.6.1.
