my self and 4 of my friends got banned from using the computers at our school for ~5 weeks. We were the geeks in the computer class.<p>Showing my age, but the class had 12 Apple IIs and a networked Corvus hard drive connecting them all for storage. The system had accounts. Each student got some space on the shared hard drive to save their work and could not access each other&#x27;s storage areas. The teacher of course could access everything and used it to read students&#x27; programs for grading.<p>One time the teacher had logged in and then stepped away to deal with something or a student. One of my friends took that opportunity to do a binary save of a large chunk of memory on that machine, the part where OS&#x2F;state extra was. Turned out if you loaded that save back into memory you&#x27;d become the teacher. He gave us all copies of the file.<p>We never used it for any kind of mischief but a few days later the teacher noticed one of us doing something we shouldn&#x27;t have been able to do. The teacher wrote our parents letters and said we were banned from using the computers till the end of the quarter.<p>IIRC only one set of parents were actually upset. I think the rest were actually kind of proud. It didn&#x27;t affect our grades. We also liked the teacher. I just thought it was his way of appropriately punishing us to make it clear even though you can do something doesn&#x27;t necessarily mean you should.
