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.
The 9.5″ 640 x 480 display normally runs in 8-bit/256-color mode, but by switching to 640 x 400 resolution it support 16-bit color.
The 2300c marked the end of the PowerBook Duo line.
