MACH II & MACH III JOYSTICKS
for the Apple II, II+, HE and IIC Personal Computers
All CH PRODUCTS JOYSTICKS provide you with the ultimate
computer control that precisely translates the position of the con
trol stick into X-Y coordinates on the screen. These precision con
trols contain two linear potentiometers, one which reads the
X-axis and is accessed by Applesoft using PDL (0) the other which
reads the Y-axis and is accessed by Applesoft using PDL (1). The
MACH II JOYSTICK has 2 pushbutton switches while the MACH
III JOYSTICK has 3 pushbutton switches. The orange pushbutton(s)
and the brown pushbutton are read using Peek (-16287) and Peek
(-16286) commands respectively.
INSTALLATION
16 Pin Connector (Apple II, II+, or HE) Plug the 16-pin con
nector into the Game I/O socket located inside your computer
on the logic board. Pin 1 must match up to Pin 1 on the game
I/O. Pin 1 is marked with a small white dot on the logic board.
9 Pin D Shell Connector (Apple ME or IIC) The 9-pin D shell
connector plugs into the outside of your computer on the
DB9 connector.
ROTARY TRIM ADJUSTMENTS
Because all computers and their software are not created equal,
each axis (X and Y) provide independent rotary trims to enable
the operator to adjust cursor positioning. This feature is most
useful while in the "self-centering" mode of operation, to adjust
the cursors return to center location. Rotating the X and Y axis
trims clockwise moves the cursor to the right and bottom of the
screen. Counter clockwise rotation will move the cursor to the
left and top respectively.

SELF-CENTERING ADJUSTMENTS
All CH Products Joysticks are designed to take full advantage of
the software developed specifically for your microcomputer by
providing you with optional self-centering or positive-true-positioning
modes of operation.
To change modes of operation simply push the mode slide switch to
the desired mode as indicated in figure 1.
Note: For correct operation the mode slide switch should be position
ed to one extreme or the other.
