In the early 80's I was doing my computing 'A' levels at a technical college. I used to type my programs on one of those old-fashioned teletypes, which I think were a cast-off from a regional polytechnic. I think the computers did have keyboards, but there were only 3 of them, and competition was tight. So I used a teletype. Making a "backup" consisted of printing the program out to paper tape. I kept the rolls of paper tape and occasionally used them as streamers, much to the curiosity of neighbours.
