I just picked up a new vintage (1983-ish) apple IIe branded joystick. The joystick seems to work well, but I'm only getting partial range for the Y axis.
The X axis is good-- I can adjust the center to a value of 127, and pushing the joystick full LEFT goes to 0, and full RIGHT goes to 255.
The Y axis can also be adjusted to center at 127, but pushing full UP goes to about 34 and full DOWN goes to about 220. So I'm not getting the full range for the Y axis. I'm happy to disasemble the joystick to see if there is a resistor or other component that is out-of-spec or something, and then replace it.
Is this something that can be fixed? Or are these values determined by the potentiometer itself that is an integral part of the Y axis, and therefore not easily serviceable? Or maybe it just isn't even worth worrying about?
