Doug McIlroy kindly sent me contact information for John Chambers,
co-author of the cited book about the S system. I have just heard
back from John, who offered a link to his summary paper from the
2020 HOPL conference proceedings
S, R, and data science
https://doi.org/10.1145/3386334
and reported that S was licensed to AT&T Unix customers only in binary
form, and that the original source code may no longer exist.
That is a definitive answer, even if not the one that I was hoping to
find.
