Does your Apple IIc or IIe joystick suffer from limited range? When you measure your X and Y axis potentiometers, are they way off from the ideal 150 kOhms? Have no fear, you can compensate for old worn potentiometers by installing a small compensation capacitor inside your joystick. This kit provides an array of different sized capacitors. You can buy any run-of-the-mill capacitors from your favorite local supplier, on-line suppliers such as DigiKey and Mouser, or you can save yourself the hassle of looking through a huge on-line parts inventory and add this kit to your cart.
All-in cost is $8 including shipping anywhere in the lower 48 US states. You kit includes two of each of the following sizes of capacitors (all numbers in nF – nanoFarads): 1.0, 1.2, 1.5, 1.8, 2.0, 2.2, 2.5, 2.7, 3.0, 3.3, 3.9, 4.7, 5.0, 6.8, 8.2, 10.0, 12.0, 15.0, 20.0, and 22.0.
You’ll need to have these tools to do the job:
- Small phillips screwdrive to open your joystick up
- Solder
- Soldering iron to add the capacitor to the circuit
- A multimeter to measure the resistance of your potentiometers

Q&A
Q: Do I have to buy your capacitors to make this work?
A: No, you can buy capacitors from anywhere in the world. Feel free to use all of our tutorials to fix up your joystick!
Q: Why are the capacitors all different physical sized and colors, and why is a 22 uF cap smaller than a 10 uF cap?
A: We have no idea, the manufacturers make these in all sorts of shapes and sizes. Sometimes the bigger cap has a smaller value and vice-versa.
Q: I have a CH Products Mach II or Mach III joystick, will this kit work?
A: Yes and no. Some of the Mach joysticks do not carry the “ground” wire into the joystick. The compensation capacitor is installed from the output of your potentiometer to ground. You might need an extra DB-9 cable, check your junk bin. We are working on a separate kit for upgrading IBM CH Products Mach joysticks over to Apple IIe/IIc.
Q: If I’m converting an IBM controller, can I just buy an adapter/dongle instead?
A: Yes, there are many, wonderful, fully functioning dongles available for sale all over the internet (and even on our website) that makes it “plug and play” easy to connect your 15-pin IBM joystick to your Apple IIC/IIe. This capacitor compensation thing is for people who don’t mind soldering, want to save a few bucks, and are sick of having lots of dongles laying around the house.
