Archives of OS/360-ish public domain software?

Are there any on-line archives of OS/360 software in the public domain? I'm thinking not only of operating system software distributions (which are rumored to be in the public domain), but also of user-group collections of software for these beasts. I'm also interested in software for previous generations of old iron, like IBM 1401's, etc. I've asked around at a couple of prominent computer museums, but they all just shrug their shoulders when I ask them how they archive and index the original software, like they've never considered it to be important. I really feel like I'm talking to all the wrong curators, because they seem to have no interest in the subject at all. I've heard of the Hercules emulator project, but I don't know what software they have archived so far, or what efforts they are currently making. If someone could point me towards an index of their software archives I'd appreciate it. I consider myself to be an expert at archiving DEC-related software, and often am involved in all sorts of projects in that sphere that benefit everyone from hobbyists to those with legal cases, but I know little to nothing about what archives of old IBM stuff are available. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
