 does anyone have a copy of the Dan Lawrence DND?? It
 used to be hosted on <http://dnd.lunaticsworld.com/> but that site's
 server crashed and the files were lost and the ownder did
 not allow the Wayback to archive it.
 I wasted so much time on that at school at
 Rose-Hulman.? A Rose student also did a lot of
 modifications to our copy. I had a tape with it once but it
 was destroyed by accident. 
Is that the one Dan Day worked on?  I'm pretty sure he did that
before I got there, but as I remember the story, he played the
game and got to the point where there wasn't really an endgame.
So he wrote a FORTRAN decompiler to turn the binary into source
that he could modify, wrote an endgame, and then recompiled
the results.
