Loses some of the charm of the photocopied original floating around the internet, but this reproduction is done for the sake of readability/searchability of the text.
Tesseract does a majority of the heavy lifting, making about a 85% transcription with minor changes needed to spelling and slightly more effort formatting it into markdown for rendering.
Pre-processing using OpenCV and tuning tesseract for the typewritten font may produce even better text.
Preserving alternate spellings not created in the OCR process.
