An annotated history of some character codes or ASCII: American Standard Code for Information Infiltration "This document is about character codes, specifically a history of ASCII(1), the American Standard Code for Information Interchange, and immediate ancestors; FIELDATA, ITA2, Murray's telegraphy code, Baudot's telegraphy code, and Morse's telegraphy code, and involves some forensic bitology. ASCII, born at the dawn of the modern computer age (1958--1965), is perfectly representative of the period; clean, spare, optimistic and ultimately ignorant of anything but its immediate past; its view of the future, our present, rosy because it was so naive." https://www.sensitiveresearch.com/Archive/CharCodeHist/
