41 ** Self Destruct Sequence
42 **
43 ** The computer starts up the self destruct sequence. Obviously,
44 ** if the computer is out nothing can happen. You get a countdown
45 ** and a request for password. This must match the password that
46 ** you entered at the start of the game.
47 **
48 ** You get to destroy things when you blow up; hence, it is
49 ** possible to win the game by destructing if you take the last
50 ** Klingon with you.
51 **
52 ** There used to be a \032 in the message (^Z), which is because
53 ** the terminal in Allman's office was an ADM-3, which uses that char-
54 ** acter to clear the screen. There was also a \014 (form feed)
55 ** because that clears some other screens. Now there is nothing.
56 ** Presumably the most general screen clear today would be
57 ** ESC [2J
