  During my undergraduate study of physics at Otago University in New Zealand in the 1970's it became pretty apparent that typing would become central to computing, so I took the Pitman speed typing class and got certified. As a certified Pitman typist from that era, I can say that there is nothing inconsistent to me about this document being typed on a typewriter. It was also common practice to use Letraset to add any characteristics to the page not otherwise available on the typewriter [1] [1] https://en.wikipedia.org/wiki/Letraset https://en.wikipedia.org/wiki/Letraset

    I was actually trying to remember exactly how I did my Master's thesis in 1981. The output was printers with daisy wheels connected to a Honeywell mainframe. I'm pretty sure I must have been able to do superscripts directly. But I may have used Letraset for the Greek letters.
