@Travis Hunt:

As already mentioned, I'm not sure if this necessarily means something (see my web.archive-links). Probably SoftWindows-1-68k also wasn't mentioned in the docs of SoftWindows-1-PPC - could anyone who ownes SoftWindows-1-PPC please confirm this (or the opposite)?

I could post a link to an Italian website that mentiones SoftWindows-2-68k, if someone is interested (and speeks Italian).
