In Scotland in the mid/late 70's you could do computing as part of a maths course, so we all signed up as "Computers Were The Future"....
Got taught Fortran by the simple expedient of handwriting code on gridded paper. These were then gathered up and posted once a week to the county computing centre where they were transferred to punch cards, the job ran, and the program listing and output printed and mailed back to us. Whole process took 2-3 weeks and if you missed a quote mark or comma and the job bombed, you had to rewrite the offending page, resubmit the following week and so on. One time I was about 8 weeks trying to get the one 20 line program to run.
