The 512Ke Keyboard
Original Macintosh Keyboard
The Color Classic originally shipped with the same short Macintosh keyboard as the original Macintosh and the Macintosh 512K, but the Macintosh Plus Keyboard with built-in numeric keypad could be purchased optionally.
Apple sold a version of the 512Ke called "512K/800" outside North America that included a full keyboard and had a M0001D model number.
ADB Mouse II
Replacing the Older Shape
Apple replaced the original wedge-shaped Apple Desktop Bus Mouse with the Apple Desktop Bus Mouse II (M2706). The Apple Desktop Bus Mouse II was a better overall design, and with its rounded edges it was much easier on the hand.
