Actually, they are slightly different, though I never ran into a problem where
the difference mattered.  The original 800 SIO port had 12V on one of the pins.
The 800XL puts out 5V on this pin.  (This is because the 800 ran off of
an low voltage AC power pack and rectified its DC internally, whereas the 
800XL runs off of a 5V DC power pack, and thats all it has to work with)
