My school had a teletext printer/keyboard attached to a BBC micro (their first school computer), which had a paper-tape reader. Its biggest achievement was when one of the geekiest in the form above me managed to get it writing patterns of holes that could be read as real letters. Very cute. The rest of us just liked the bell character, which of course was a real bell. It was several years (and many cassettes) before the school BBC got a proper floppy drive.
Later, when we had a room full of computers (I forget what sort) we got a proper computing teacher. It was the maths teacher, though (a formidable lady and superb teacher) who policed the no-games policy. She never used a stapler, but was paranoid about the way every time she went in the room there would be a collective "BEEP" as everyone hit the break key simultaneously (remember, in those days the break-key was hard wired to the reset pin of every chip in the computer, and caused an instant reboot, getting you out of trouble if you were in mid game; remember the days when booting took a microsecond?).
The computer teacher spent hours trying to get us to draw a simple rectangle. I got so bored. I remember my rectangle flashed on and off, but I was completely out-classed by our form's greatest geek: his was set up to wait for a couple of seconds while the teacher appreciated it, before starting to bounce gently round the screen.
