As part of my on-going quest to fill my apartment (and hackerspace) up with semi-working 1970′s supercomputers, my effort to revive the Cray-1 supercomputer needs your help! Through the grapevine, I managed to get my hands on a genuine backup disk pack of the once-thought-extinct Cray Operating System (COS). Using my homebrewed disk reader I was able to make a copy of the disk, and the folks over at the internet archive (thanks Jason!) were kind enough to host it for me. Now is where you, kind reader, come in! Help me reverse-engineer the file system so I can recover the actual operating system files and take a step closer to towards booting this awesomely-useless machine!
Download it and get hacking!
