DistroWatch.com has found a non-publizied link to SUSE 9.1 Personal ISO. This would be the equivalent of Red Hat's Fedora Core, since this version of SUSE has no commerical software.
This is a great way to try out SUSE LINUX 9.1 and see its
capabilities, before upgrading to the Professional edition via FTP or purchasing the full boxed versions (which includes commercial software). Download from here: SUSE-9.1-personal-x86.iso (700MB) or try one of the official SUSE mirrors.
