Sorry, but you are not correct. The IBM Executive model, which was in common use during the 1970s, was capable of all of these things. It was famous for having proportional typing capabilities. Centering was as simple as setting a tab stop and using the correct keys to backspace half of the line length

Look at the centering. There are 3 lines perfectly centered. How can you back space from a center tab stop proportionally and get perfect results like this? The typewriter does not know what you are going to type. I remember when Wordstar came out for the PC, and this multi-line centering stuff was really gee-whiz tehnnology.

The Executive was well capable of this. Remember, it was only delivered with one font. There were multiple-width space and backspace keys, and you could accurately move the carriage to do type-setter-like work. This was a professional machine, designed to be used by highly skilled typists.

Somebody's going to reproduce this thing on an old typewriter, and then we will wish we concentrated on the obviously forged signature, fake P.O. box, and suspicious content of these docs.
