The only copy I could find was a PDF that contained images of the original paper, literally printed on paper. It seemed worth redoing and putting online properly.

I've tried not to change anything beyond the typography, but it's tricky to get perfect. It's on GitHub, so feel free to chip in.

Can you link to the scanned PDF and your GitHub repo? I've noticed a few places with mismatched brackets, such as "(....]", and wanted to check to see if they were mismatched in the original or if that's just a transcription error.

edit: Found the original at http://hall.org.ua/halls/wizzard/pdf/vaughan.pratt.tdop.pdf and your repo at https://github.com/tdop/tdop.github.io. Am reading the paper now, it's not one that I'd read before so thanks for posting it, and will send a pull request with suggested fixes when I'm done.

There seem to be a number of places where you've changed hyphens to em-dashes. (E.g.: "This argument is independent of whether we specify program control explicitly, as in Algol—like languages, or implicitly, as in Planner—Conniver-like languages.") It's a bit confusing to read. Would you possibly mind fixing this? Thank you!

I collected up a number of nits like this, plus some more meaningful transcription errors, into a branch, and have sent a pull request: https://github.com/tdop/tdop.github.io/pull/2
