It documents the different locations where the inventor Charles H Moore worked and optimized Forth.
MIT 1958, Stanford 1961, Freelance 1965, Mohasco 1968, NRAO 1971.
Within programming community there is a very strong feeling about this language - for it and against it, often quite emotional.
Charles' moral from the eBook:
I know Forth is the strongest language so far.
I'm disturbed that people who should don't appreciate how it embodies their own description of the ideal programming language.
Forth has lead to an architecture that promises a wonderful integration of software and silicon.
One way it has been described: You need longer to learn it to work with it efficiently - but from then on you will program faster. The same even seems to apply if the programmes steps back to her/his language of choice.
