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.
Now, would anyone go to this trouble for a memo? I doubt it. And I do think the docs are forged. But let's all stay clear on the real evidence, and not end up falling into a trap here.
Maybe so, but would typing that letter on the IBM Executive have the *exact* overlay that typing it on MS Word does? I think not.
I work at a Help Desk. One of the partners in my firm wrote a book when we were using Word Perfect. He wanted to print out a few more copies but we had since converted to MS Word. Now, we used the same computers (different software, though), the same font (Times New Roman, coincidentally), the same pitch and could not get the text to line up exactly. We had to change the parameters (i.e, condensing white space, kerning, line height spacing) for almost *every line* in a 200+ page book to get the same line breaks and page breaks in Word as we did in WordPerfect.
And this was no 30 YEAR DIFFERENCE in technology -- no more than 3!
So if you can show me that you can get an exact overlay from a 30 year old typewriter as you can from MS Word I would be very interested to see it!
The th would not have been smaller. You had to roll the paten (carriage) to superscript, but it did not make the letters smaller,just raised where you were able to slide the paten.
The line pattern could not have been replicated on Word, as it has been shown to be many times over by many different experts/bloggers, etc.
but there that matter about the 4 and the apostrophies, which did not exist at all in said font......
