Aren't the SCCS sources for the real history

them available on his CD, I have them somewhere.
In a previous private e-mail I received from Kirk, he said:
The folks at UC
Berkeley have always required me to track distributions of the SCCS
files as they somehow think of them as still sensitive.
which implies that the SCCS files cannot be released publicly. However,
the SVN version is a "derivative" of the SCCS files and, on that basis,
is publicly available. Go figure :)
Here's another data point: when I asked Kirk regarding the public
availability of the SCCS repo he pointed me to
you can find a single
1GB repository that integrates many of the snapshots and version control
repositories available through TUHS and other sources (including the
CSRG data). Its commit history starts on Jun 20th 1972 with the First
Research Edition and ends with FreeBSD 10 in 2015. Git blame works
across all the history's commits.
