When I was in college, I had to use a typewriter......
I would have given anything to have a word processor. They simply weren't affordable when I was in college.
I remember cutting up papers, so that I could insert paragraphs without having to type the entire thing over. If you left something out, you either had to literally "cut and tape" the thing back together, or type it over.
I had professors who wouldn't accept taped together papers, so you were stuck with retyping those. There were people who would type papers for others for a fee and they made good money.
I'm dating myself.
