>in 2006 was still using svn

Perhaps you meant cvs? Subversion was released in 2004 and git appeared in 2005.

Subversion 1.0 was released in 2004, but it was already widely used before then.

We used cvs, but did switch to svn before/around 2006, but I could be mixing that up. We did not switch to git even by 2012 when I left.

The reference to the 70s and 80s code didn’t imply it was version controlled before svn/cvs though if that’s what you meant, but by that time it was and still had old timestamps commented in the text files.

I just wanted to say that "still using svn in 2006" sounds odd when talking about version control system that existed just for several years and what turned out to be its replacement was 1 year old.

gcc, for example, transitioned to subversion in 2006 and switched to git only in 2019 [0]
