The Duo 270c featured a 33 MHz Motorola 68030 processor. It was the first model with an active matrix color display 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.Duo Dock by Billie Hawkins, Apple Macintosh Museum. Accessed 2021-05-02.
