the PC "FlightStick" when plugged into our Apple II+.

Most likely, you will find that the a stick tops-out too early in the

X and/or Y

max direction. For best control precision, what you want is for extreme

values to occur near the extremes of stick movement:

X (horizontal) Left= 0 Right= 255

Y (vertical) Up= 0 Down= 255

For adjusting, use a program which continuously reads and displays X

and Y stick values. The program below does this and displays "B0" when

Button 0 is pushed and "B1" when Button 1 is pushed. Do a CTRL-C to exit.

20 PRINT "X= "; PDL(0); TAB(15); "Y= ";PDL(1); TAB(30);

30 IF PEEK(49249)>127 THEN PRINT " B0";

40 IF PEEK(49250)>127 THEN PRINT " B1";

50 PRINT: GOTO 20

Experiment with capacitance values between .002 uF and .01 uF to get

the best 'spread'. For easier fine-tuning, add the 50K-100K trim pots in

series with each capacitor.

The converter I built fit inside heat-shrink tubing. Putting it in a

small plastic box may be better. You can mount the trim pots (and/or

switches with fixed "trim resistors") and select between settings for a

'fast' (short swing) Game Stick and 'normal' (full swing) Graphics Stick.
