The documents could have easily been done with superscript in 1972. "After the Selectric II was introduced a few years later, the original design was designated the Selectric I. The Correcting Selectric II differed from the Selectric I in many respects: The Selectric II was squarer at the corners, whereas the Selectric I was rounder. The Selectric II had a Dual Pitch option to allow it to be switched (with a lever at the top left of the "carriage") between 10 and 12 characters per inch, whereas the Selectric I had one fixed "pitch". The Selectric II had a lever (at the top left of the "carriage") that allowed characters to be shifted up to a half space to the left (for inserting a word one character longer or shorter in place of a deleted mistake), whereas the Selectric I did not. The Selectric II had optional auto-correction (with the extra key at the bottom right of the keyboard), whereas the Selectric I did not. (The white correction tape was at the left of the typeball and its orange take-up spool at the right of the typeball.)
