China DOS Union

I want to ask about a topic unrelated to DOS. Does wiengier or any other moderator have an early UNIX operating system, that is, something relatively small? Because of my network speed, I can't download those things nowadays that are several GB at the drop of a hat.
Sorry for asking some off-topic questions at an inappropriate time. I hope other netizens won't scold me after seeing this. I also hope that if any netizen has it, please provide it. My MAIL: YIYESONG@SINA.COM. Thanks in advance.
