Apple Adjustable Keyboard

Contexto histórico

The Apple Adjustable Keyboard was introduced in 1993 at a retail price of $219 U.S. The keyboard attached to the computer via the Apple Desktop Bus (ADB). It aimed to solve repetitive stress injuries resulting in carpal tunnel syndrome, after several computer keyboard manufacturers were sued for poor design. The Apple Adjustable Keyboard came with contoured plastic wrist rests, and a separate keypad with function keys and arrow keys. This was the third and last time Apple offered a separate numeric keypad. Unlike its predecessors, it was not sold separately. The keyboard also included volume buttons and a record button on the right side of the keyboard. It was hinged at the top, allowing the user to adjust the angle between the right and left sides of the keyboard. The split came between the key pairs: 5/6, T/Y, G/H, and B/N. The space bar floated midway between the two parts.
