SCCS was released in 1977 and it hasn't even turned up in these comments at all. "Not evenly distributed". (I introduced RCS as a replacement for "just editing files" at a job in 1990; "there's a man page and some binaries on the system" really doesn't contribute to adoption. CVS at least propagated through things like USENIX, because solbourne made cool toys and talked about the challenges.)
