The US versions of the AppleDesign Keyboard and the Extented Keyboard II have the same key layout. However, there are some subtle differences in the overall design of the keyboard.
- The Extended Keyboard II has two ADB connections, one on the right side, and one on the left side. The AppleDesign Keyboard has one ADB connection on the underside of the keyboard for a mouse or other pointing device. There is a 6-foot long cable permanently attached at the front of the keyboard for connecting it to the Macintosh.
- The Extended Keyboard II has a multi-position switch at the back of the keyboard for adjusting the keyboard angle to several positions. The AppleDesign Keyboard has two feet on the underside for raising the keyboard angle.
- The AppleDesign Keyboard is slightly smaller and lighter.
