We had a teletype machine at my school in 1980 connected to the local authority mainframe. There was nearly always a queue to type your own program but you could write it out on a sheet of paper (one character per box) and get a printout of somebody who had typed it in for you. When they made a mistake your program didn't run and you had to send it again the next week. and I'm only 50!
