Well, after doing *heaps* more cleaning with contact cleaner and a
slight bit of manipulation of the pot internals (the sweeper?), I have
managed to get the old joystick functioning pretty well (and no
soldering was required). The erratic behaviour has gone completely,
however, I am still facing the problem whereby one of the pots only
gives a range of  0-225 (ie. using the applesoft joystick test). BTW,
this was the pot that I did not "manipulate" the internals of
(hmmm....maybe I should).

Is there any easy way of fixing this, or is this the problem of
linearity that you mentioned is hard to fix?

I imagine most games would function OK with this range, however, the
game I tested it with (Sensei) did not respond to downward movements
(ie. moving the stick in the limited 0-225 axis). I read that you can
counter this when converting an IBM style joystick by introducing a
capacitor to increase the resistance somehow. Would it be possible to
do something similar here to increase the range?
