Subject: Delete previous submission! Space Duel: Add the P10/11 dip
switch

Delete previous submission!  Functionally the same, just reordered 
some source and added a comment.  Thanks!


Space Duel: Add the P10/11 dip switch (only 4 switches instead of the 
standard 8)

Let me know if you have any questions.

Franklin
