  On any unix system this is a problem. Go up to a micro version of unix.
Reboot from a floppy with a small unix kernel on it. (say XENIX and the XENIX
distribution disk). you will now be superuser. Edit the /etc/passwd file so
that root has no password. Reboot. Anytime anyone has full access to a system
you don't have security. That's why god created machine rooms.

  Note that the above instructions were taken from the Microsoft XENIX manual
What to do if you Forget the SuperUser Password. Bozos.

Today's scientific question is: What in the world is electricity?

And where does it go after it leaves the toaster?
