My Dad had one of the first Macintoshes and a dot matrix printer. I have a ton of those sheets. None of the digital copies.
I had a ton of Tales From The Floating Vagabond sheets that I printed out on a dot matrix... brrrrrrrrrrrrrrrrrrnt brrrrrrrrrnnnnnnt
Back in the day (82 or so) I didn't know where pre-made character sheets came from; probably I saw some that older kids at the library group had, but the idea that you could buy them (e.g. the goldenrod AD&D ones) either never occurred to me or seemed too expensive. So I sat down with a typewriter and laid out my own, by the expedient of going across each row, typing in the things I wanted on that row, and then putting in a : where I wanted a vertical line between sections to appear, then doing it again on the next row with the : hopefully lining up with the one above. How much time and White-Out I spent on this cannot be imagined. (I did then have my dad copy it at his office, though - I didn't do it every time I wanted to make a new character).
If you go to Mammoth Cave in Kentucky, you can still find the character sheets that me and Grog carved into the wall with stones for our games. That's how far back in the day I go.
