45 **  Self Destruct Sequence
46 **
47 **	The computer starts up the self destruct sequence.  Obviously,
48 **	if the computer is out nothing can happen.  You get a countdown
49 **	and a request for password.  This must match the password that
50 **	you entered at the start of the game.
51 **
52 **	You get to destroy things when you blow up; hence, it is
53 **	possible to win the game by destructing if you take the last
54 **	Klingon with you.
55 **
56 **	By the way, the \032 in the message is a ^Z, which is because
57 **	the terminal in my office is an ADM-3, which uses that char-
58 **	acter to clear the screen.  I also stick in a \014 (form feed)
59 **	because that clears some other screens.
