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