They are simple.  The paddle controllers use two player boxes
for each DB-9.  Each of these little boxes contains a pot and
switch.  I'd have to open mine (again) for details.  The joystick
boxes use one DB-9 per player.  They contain 5 switches.
5 volts is also available (either pin 7 or 8 I think).
I think the pots go to pins 5 and 9, but I can't remember if they
are tied high or low.  Atari computers also use these.  I've
used them to control my direct digital synthesis signal generator
from my atari 400.  I bet you can find some old paddles at a
garage sale, probably with a cheap VHS too.
