At the university we were a few hundred undergraduates using two VAX
780s through about 40 serial terminals. They were running 4.3BSD. It
was common for students who would leave their terminal for a few minutes
to lock(1) it, so that others wouldn't mess with their account.
Sometimes terminals were forgotten with the lock program running, and
then a staff member would come, type some magic characters, and exit the
lock program. Through shoulder surfing a student had found that magic
sequence, and some of us were led into this secret. What we didn't know
at the time, was that the magic character sequence was the root password.
