5. Label each of the leads coming from the PC cable. If it is still connected to
a joystick, the following pic will help identify each lead:
PC Joystick
(15-pin male connector)
[1]--------------- +5V
[2] -------------- Button 0
[3] -------------- X-axis
[6] -------------- Y-axis
[7] -------------- Button 1
[4] and [5] ------ Ground
If the cable is still connected, snip the the leads once they are all labeled.
If both Ground ([4] and [5]) leads are present, twist them together and treat
like a single Ground lead.
FINISHING UP
6. You have six labeled wires in the Apple2 joystick case: +5, GROUND, B0, B1,
X, and Y. The same six leads are labeled on the PC cable. Splice each Apple2
wire to the corresponding PC cable wire. Use heat-shrinkable tubing to cover
each connection.
7. Seat the new cable in the joystick case, arrange leads to avoid mounting
posts, etc., and close up the case. Viola!
CHECKS
If you have an Ohm meter here are some checks you can do:
X (Horizontal) Check- check R between cable pins 1 and 3. As you move stick left
to right R should go from 0 to about 100k.
Y (Vertical) Check- check R between cable pins 1 and 6. As you move stick up to
down R should go from 0 to about 100k.
Button 0 Check- (Button 0 is the main, "Fire" button.) cable pins 2 and 4 or 5.
It should be very high and go to 0 when Button 0 is pressed.
Button 1 Check- check R between cable pins 7 and 4 or 5. It should be very high
and go to 0 when Button 1 is pressed.
TRYOUT
Plug in the stick and try it with a game.
Some games (such as Elite Plus) will claim no joystick is present if the stick
is badly out of adjustment. If this happens, try the stick on a game which is
less picky and includes pre-play stick adjustment.
