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