PowerBook Duo 2300c

The PowerBook Duo 2300c/100 was a color subnotebook from the PowerBook Duo line that was introduced by Apple Computer on August 28, 1995.

Features
The Duo 2300c featured a 100 MHz PowerPC 603e processor with a larger 9.5" color display which supported 640x480 in 8-bit color, and 640x400 ed in 16-bit color. The logic board contained 8 MB of RAM which could be upgraded to 56 MB. It also included an improved Type 3 battery.

The Duo 2300c 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 2300c shipped with System 7.5.2 (with PowerBook 5300/2300/190 Enabler) and could be upgraded to Mac OS 9.1.

Upgrade kit
Apple also offered a PowerBook Duo 2300 upgrade kit for owners of earlier PowerBook Duo models. It included a replacement logic board with 100 MHz PowerPC 603e processor, a new case bottom, stiffener assembly, 36-watt power adapter, and a PowerPC name plate sticker to indicate an upgraded unit.
