Joystick

The joystick is a mechanical device used to do rotations in MGED. Any movement left or right rotates the display about the X-axis. Any movement up or down rotates the display about the Y-axis. When the joystick top is twisted in a clockwise or counterclockwise direction, the display rotates about the Z-axis. Any combination motion of the joystick will produce a ``combined'' rotation about the appropriate axes. As implemented on the Vector General hardware, all of these motions have a spring return to a null center position.
