Download ClefOS for System z

Use the file list below to obtain the installation files needed for your preferred ClefOS version. The links are direct, so you may copy and paste the link URLs if you are downloading with wget, curl, or similar command-line utilities. If you are downloading with a graphical web browser, you will want to use your browser's "Save Link As..." feature (usually in the right-mouse context menu for the link) to directly save the file rather than viewing it. If you prefer, you may also use our unformatted file list.
