The Apple Extended Keyboard was released in April 1987. This keyboard was first sold separately alongside the Macintosh II and SE. Later the Apple Extended Keyboard II was prepackaged with Apple Professional Desktops during the early 1990s (starting with the Macintosh IIsi in October 1990).
These keyboards are widely considered by enthusiasts to represent the golden era of Macintosh Keyboards and are fondly remembered by many. Retrospective articles credit the success of the product to a combination of sound, feel and durability.
Some features of the Apple Extended Keyboard include: caps lock key that physically locks down when activated, which is considered to be better for touch typists, large spacing between keys, especially the top function keys, the width of the keyboard matches the width of the Macintosh II and the height allows it to fit under the "chin" of the Macintosh SE.
The Apple Extended Keyboard was discontinued in 1990.
