The following is a message from Dennis Beach at Purdue..  He does not have
authorization to post to the net, so I am relaying this for him:
-------------------------------------------------------------------------------

    For a long time I have been wanting to experiment with the parallel port
in the back of my 800XL.  However, I can't find any info whatsoever about
it.  I have the XL supplements to the tech notes, but it doesn't even mention
the port.  I would like to know what locations control the port, and what
each pin does.  Also, is there a standard type of jack that will plug into the
port?  If so, what is it called so I can ask for one in a store?  I would be
greatly appreciative if anyone could give me this information or tell me where
I could find it.
