Not to mention how every Apple II box with the 9 pin joystick port has a
little paddle or joystick icon next to it to identify the port. Anyone who 
can botch that is in a bad way.

I thought most parallel ports had a Centronics 36 pin jobber. But anyway,
it seems that if you have the savvy to install cards, you can also keep
track of which port is what. You'll notice that on all Apple boxes, the
built in ports have icons to identify them.
