In my last year of high school in the 70s, the school acquired a Business Basic 4 computer to do some of the administration work. They also created a computer class for the students, where we punched out programs on punch cards, and the teacher would batch run them overnight.

The teacher did not allow any students near that computer, as he was sure we were going to hack it and wreck everything.

(Yes, hacking was a thing even in the 70s!)
