I'm not sure who maintains it but you can Google it and download a live CD. But caveat emptor, when you run it, It assumes you are installing it and it will rape your hard drive, and convert it to FAT32 if it fcan't find a FAT partion to make it's swap file on. Won't hurt a windoze install though. It mostly resembles OS/2 Warp 4, and when I tried it, it seemed primitive. I love Solaris, but don't have a machine to piddle with it on. Now that it's open source there are several distro's you can try. I want IRIX to hit the free market too.
Oh...I'm a tool....here's the link.
