ASCII was used by teletypes, not typewriters. They were "cylinder" heads, as compared to IBM's golfball typewriters. The endless CR/LF/CRLF line ending problem would have been solved if the RS (Record Separator) ASCII code was used instead of the physical CR = carriage return, ie move print head back to start of line, and LF = line feed, ie rotate paper up one line. But Unix decided on LF, Apple used CR, Windows used CRLF, and even today, I had to get a guy to stop setting his system to "Windows" because he was screwing up a git repo with extraneous CRs.
