The Python source - https://github.com/python/cpython/ - with full commit history back to 1990.

The Unix source - https://github.com/dspinellis/unix-history-repo - with quite a number of releases dating back to 1970.

Had no idea the Unix source was out there, very cool. Weird to see "53 years ago" on GitHub. Thanks!
