The MouseStick actually consists of two units: the stick itself and the Gravis Mouse Processing Unit (GMPU). The stick is mounted on a wide, stable base with rubber feet, and is connected to the GMPU, which plugs into your joystick or mouse port. There are two fire buttons on the base and one on top of the stick.

You can set the base fire buttons to emulate your right and left mouse buttons, or to emulate your left mouse button and activate the MouseStick editor.

The mouse editor lets you configure the MouseStick and includes a variety of options. Since the GMPU has only a single-line LCD display, however, programming it is slow and somewhat tedious. You can save up to four configurations (three plus the default configuration).

Enter the editor for a true test of your trigger finger; you have to push the designated editor button three times fast and hold it down on the last press. The editor gives you a list of options the most complex of which is RECALL A SETUP Besides letting you recall any one of the four configurations, it lets you set the MouseStick for AUTO CENTERING, VECTORING, COMBINATION or JOYSTICK modes.

AUTO CENTERING gives you direct control over the mouse pointer and returns the pointer to the center of the screen when you release the stick. In VECTORING mode, the pointer position glides across the screen in the direction of your stick handle's movement. COMBINATION mode provides a combination of AUTO CENTERING (when the stick handle is upright) and VECTORING (when it's moved left and right). JOYSTICK mode sets the MouseStick to emulate a standard eight-position joystick.

PROGRAM A BUTTON option allows any of the three buttons on the MouseStick to be set in TURBO FIRE mode. This is handy for some games, although rapid fire attachment for joysticks are sold at most toy store for about five dollars.
