  14: **  Self Destruct Sequence

  16: **	The computer starts up the self destruct sequence.  Obviously,
  17: **	if the computer is out nothing can happen.  You get a countdown
  18: **	and a request for password.  This must match the password that
  19: **	you entered at the start of the game.
  20: **
  21: **	You get to destroy things when you blow up; hence, it is
  22: **	possible to win the game by destructing if you take the last
  23: **	Klingon with you.
  24: **
  25: **	By the way, the \032 in the message is a ^Z, which is because
  26: **	the terminal in my office is an ADM-3, which uses that char-
  27: **	acter to clear the screen.  I also stick in a \014 (form feed)
  28: **	because that clears some other screens.
