X (horizontal) Left= 0 Right= 255
Y (vertical) Up= 0 Down= 255
This way, you have lots of active swing which makes graphics work and playing
most games much easier.
If you included the trim pots in your converter, adjusting for maximum
active swing will be easy so long as you can get to the max 255 values with the
pots at lowest resistance. (Increasing the resistance acts like lowering the
value of the connected capacitor.) If your converter does not include the trim
pots, experiment with swapping in capacitance values between .002 uF and .01 uF
to get the best control 'spread'.
The converter I built fit inside heat-shrink tubing. Putting it in a small
plastic box may be better. You could mount the trim pots (and/or switches with
fixed "trim resistors") and select between settings for a 'Fast', short swing,
'hot' Game Stick and a 'Normal', full swing, 'cool' Game/Graphics Stick.

005- I have a great Apple II joystick I'd like to use on
my PC. How can I do an Apple-to-PC Joystick conversion?
If you've compared the pinouts and info for Apple II and PC joysticks, then
you know there are some important differences:
The Apple II stick uses a 9-pin plug vs. the PC's 15-pin plug. (Older Apple II
sticks may use a 16-pin plug which fits in an IC socket.)
The Apple II stick's X, Y controller potentiometers are a bit larger.
The buttons are wired differently.
You can use an Apple-to-PC adapter (such as the one supplied with the Epyx
A2/PC joystick) to handle plug conversion; or, you can replace the entire cable
with one from an old PC stick.
The PC's joystick interface will work with the Apple2 150k pots; but, in
some applications, you may notice a tendency to max out early in the stick
swing. You can correct this by connecting a 300k resistor across each pot (from
the center to the end with a wire going to it).
The difference in button wiring is the main reason an Apple-to-PC
conversion involves opening the joystick and making changes. (The Apple stick
has a slightly more complex, less flexible circuit. Apple2-to-PC is not as easy
as PC-to-Apple2.)
Basically, you need to change the Apple stick's button wiring so that it
looks like the PC stick's button wiring.
