ABSTRACT:
A system which is physically oriented in a vertical plane, is attached to a wall, and has a hinged keyboard. The keyboard is attached to the system solely by a hinge which has at least three positions. The hinge has a closed position to minimize space when the system is not used, an open position during normal use, and a breakway position to release the keyboard when excessive pressure is applied. The breakway keyboard eliminates damage caused by excessive pressure placed on the keyboard due to a person leaning on the board.
