The first version control system I ever used was CVS and it was first released in 1986 so it was already old and well established when I first came to use it.

Anyone in these past forty years not using a version control system to keep track of their source code have only themselves to blame.

CVS was, for the longest time, the only player in the FLOSS world. It was bad, but so were commercial offerings, and it was better than RCS.

It’s been completely supplanted by SVN, specifically written to be CVS but not broken, which is about exactly as old as git. If you find yourself using git lfs, you might want to have a look at SVN.

Somewhat ironically RCS is still maintained, last patch a mere 19 months ago to this… CVS repo. Dammit I did say “completely supplanted” already didn’t I. Didn’t consider the sheer pig-headedness of the openbsd devs.
