Hm, strange, when I unpack the zip file again, I get the following (on OS X), so it seems the resource forks are intact. The file was generated using Finder on OS X 10.9, which is aware of resource forks as far as I know (in contrast to the zip/unzip command line tools). However, the FinderInfo is missing compared to the stuffit file posted by mac1zzz.

I could also generate a floppy image if it helps...
