I typed many term papers and theses on regular typewriters and electric typewriters through the years, and none of them, even the Selectric I used, had the superscript capability. When I had to put in a footnote, I used to have to turn the roller part way down to position it slightly above the rest of the line, then use the number key to denote a footnote number. The footnote number was always the same size as the rest of the letters you were typing because there was no way to reduce it in size.
