It seems that the author never used a typewriter! The typewriter has tabs, so that you can center the equal sign, for example, after 3 tabs, and the alignment will be perfect each time. Most probably Dennies Richie sent his manuscript to a professional typist who provided services to the university, unless he was adept at spend several hours typing until he got professional results.

Or possibly multiple typesetters, as the disparate "4" versions may imply.

> It appears that Dennis was able to replace incorrect copy with new text in the surrounding original copy, but note the extra space in the corrected version. Other than corrections, the January and February versions are identical in every way: February is not a new version, but a copy of the January draft except for corrections. ... The natural explanation is that he used white-out and a Xerox copy machine. Except that there have been no reports from anyone from this era that white-out / replace / Xerox editing treatment was possible at the precision and reproducibility seen here.

Could he have simply retyped the entire page?
