Original DOS Arcade Volleyball sources

[Lohoris]

Hope you don't mind the questions: are the sources for the original DOS Arcade Volleyball available somewhere?

I've read that it has been compiled with Borland C, ok, fine, but I couldn't find the sources, just this vague statement.

Yes, I am aware that there has been an open-source clone called GAV, but I tried that years ago, and the physics felt completely different, like if it was rewritten from scratch (as it likely was), and not terribly faithful to the original IMHO.

Side-question: again, sources claim that the original author is "Rhett Anderson" and that he released the game under public domain… but is there any actual proof of that, anywhere?

Thank you in advance in case anyone manages to find an answer!
