What's a fun operating system I can play around with in a VM? I was playing around with Windows 95 recently since I missed using it and actually built an old 486 to use it properly with. But I want to try something else. It could be a Windows OS, Linux, Inbox, BSD or something else. I've played with Haiku and like it so I don't want to use that again.

Pls respond and let me know.
