   48: **  Self Destruct Sequence
   49: **
   50: **      The computer starts up the self destruct sequence.  Obviously,
   51: **      if the computer is out nothing can happen.  You get a countdown
   52: **      and a request for password.  This must match the password that
   53: **      you entered at the start of the game.
   54: **
   55: **      You get to destroy things when you blow up; hence, it is
   56: **      possible to win the game by destructing if you take the last
   57: **      Klingon with you.
   58: **
   59: **      By the way, the \032 in the message is a ^Z, which is because
   60: **      the terminal in my office is an ADM-3, which uses that char-
   61: **      acter to clear the screen.  I also stick in a \014 (form feed)
   62: **      because that clears some other screens.
