Hi, is it possible that snowleppard isn't supported by the modern bootloader on your 2013-2014 systems? I don't see why this shouldn't work, but maybe if you google the above you will turn something up.
Also, if you happen to have either another old hard drive or a 128 gb sd card, why not try a clean install of snow leopard using your modern mac and see if it flies? Then swap the media back into your old machine and see if it boots? Finally, as I'm writing, I seem to recall that network administrators had some issue with deployment on snow leopard. Unfortunately that was 7 or so years ago, and I don't remember what the issue was. It's possible that Snow Leopard was restricted to run on the hardware where the installation was performed, especially if you used the home version and not the server version.
