- rbanffy 2y agoThe stick that got slower responses the further you pushed it towards a corner.
- amelius 2y agoIndeed, it was resistance based and it used a timer to measure the resistance.
- grahamj 2y agoheh my friend and I (young teens at the time) used to wire photoresistors into the analog in pins on the joy port. We put the sensors in toilet paper tubes on one side of a hallway with small lights across from them and wrote BASIC code that would turn on a light via the annunciator outputs when change was detected. Then we’d see if we could sneak down the hall undetected, Mission Impossible style. I never noticed the detection speed varying with light level but I guess it did!

I took an Apple analog joystick apart when I was in junior high and measured the resistance in all directions. Then I took a Wico "bat-handle" digital joystick apart and wired resistors in to simulate the full deflection of the analog joystick. Then I had to cut the 9-pin plug off and solder the necessary wires to a DIP plug to go into the Apple computer. The Wico joystick already had two buttons, which were necessary for the Apple (ironically, considering Steve Jobs's stand on multi-button mice years later). I wrote the whole thing up as a how-to article for Compute magazine, but I don't recall what response I got to the submission. They didn't publish it, but the thing worked. I still have my one prototype around somewhere in its original box.
