A guy I knew who was considered an RSTS/E guru had already beaten us to the booth. Years before he had been one of the guys who had challenged me to break into the DEC internal development computer, after which his associates had turned me in. Since those days he had become a respected programmer. We found out that he had tried to defeat the LOCK-11 security program not long before we arrived, but had been unable to. The incident had given the developers greater confidence that their product really was secure.
