First available in Canada (1993), and then Asia and Europe (and never sold in the home US market), the Colour Classic II (also known as the Performa 275) shares the motherboard design of the LC III. Running at a relatively fast 33 MHz, memory can be expanded as far as 36 MB.

Colour Classic IIThe CC II/Performa 275 and Performa/LC 550 share the same motherboard. If you ever need to perform a motherboard transplant, a 550 makes for a very inexpensive donor.

This is what the Color Classic should have been. It is also quite rare on the used market and commands a premium price, especially in the US.

The Colour Classic II was the last Mac with a built-in 10″ (9″ viewable) color monitor.
