Apple Adjustable Keyboard (1993)

The Apple Adjustable Keyboard is Apple’s only ergonomic adjustable keyboard. This keyboard was released in 1993 and used the then-standard ADB (Apple Desktop Bus) port to connect to Macintosh computers. The QWERTY keyboard is split down the center between the 5/6, T/Y, G/H, and B/N keys, while a large space bar remains fixed in the center. The keyboard can be split up to 30 degrees, and palm rests are included to support the wrists while typing.

The keyboard shipped with a separate, ADB-connected numeric keypad, also with a palm rest. The keyboard and numeric keypad each have feet to raise the keyboard to a steeper angle.

The purpose of this ergonomic design was to resolve repetitive stress injuries that could lead to carpal tunnel syndrome. The primary problem with this keyboard is the vast amount of desk space that is required to use it.

The Keyboard packaging provides the following information:

The Apple Adjustable Keyboard has been ergonomically designed to make typing more comfortable. Its features include:

  • A split alphanumeric section that can be adjusted from a standard typewriter-style configuration to an open-angle configuration.
  • An adjustable keyboard slope and optional palm rests (included), which help your forearms and hands assume a neutral, more comfortable position.
  • A separate extended keypad (included in this package) with 15 function keys, 6 special keys, 4 cursor-control keys in a standard inverted-T layout, and an 18-key numeric keypad.

Please read the manual that comes with this keyboard to find out how to best use this product. Be sure to read the “Health Concerns Associated with Computer Use” section.
This keyboard is compatible with all Macintosh computers equipped with an Apple Desktop Bus connector and system software version 6.0.7 or later.

The keyboard uses two types of switches/buttons: ALPS SKFS switches for the keyboard keys (providing “clicky” tactile feedback) and recessed buttons for the function keys, volume, power, and other non-typing controls.

I have two of these keyboards in my collection. One includes the original box.
