- Allows you to use two analog or two digitial joystick. Not exactly
- what you're looking for (convert the digitial signal to analog), but
- allows you to use those 'ole Atari Sticks.

- Why? because it doesn't translate those (digitial) signals into
- something that you could read via PDL(x). The joystick positions and
- button status' were converted into various combinations of the push
- button switches & things (been a long time, can't remember too well)
- I still have the manual around here somewhere, 'should dig it up.
-
- I suppose one reason they stopped making it is because of
- (ready for this?) the Apple //e. Before the //e there was no
- such thing as Ctrl-OA/CA-Reset, so the Joyport was able to make use
- of what was to become the Apple Keys.
- When you have the joyport set to digitial (you could use analog
- sticks, or digitial sticks, but not both) and nothing plugged in, it
- causes the computer the think the game buttons are being pressed. So
- if the joyport was like so and you reset the computer, it thinks you're
- doing a Ctrl-OA-CA-Reset, throwing it into the self-test with the high
- pitched screech. (what caused that anyway? =^)
