Late September 2008 I asked some questions on the topic: Atari
Joysticks on Apple II using "Atari Joyport"
Thanks for all the help. It got me going in the right direction.
Now that I have completed it you can see the Atari Joystick to Apple
II's "Atari Joyport" converter here in my blog:

The way in which the Joyport works it sets PB0, PB1 and PB2 to the on
state when the joystick is not in use. Since PB0 and PB1 are tied to
the Open-Apple and Closed-Apple keys this causes a problem during
reboot ie you get a self test instead. I would be interest to hear if
anyone has a better work around than the ones I came up with.
Cheers,
Alex.
