The original Marc Rochchild/John Mashey and team code from PWB 1.0 can be
found:  http://tuhs.org/Archive/Distributions/USDL/spencer_pwb.tar.gz
In the directory: sys/source/sccs4
The man pages are in the same archive but mixed with the rest of the
commands in usr/man/man*

That said, there is Gnu version of same written C++ if IIRC:
https://www.gnu.org/software/cssc/

And there's more ... but I'll Larry offer details here other than point out
his: http://www.bitmover.com/bitsccs/ [which is of BitKeeper] is a
more modern implementation still]
