Yes- I noticed the readme in the version of DiskDup+ I was using was dated
'89, long before the new-style drives and controllers came out.   So we now
know it could have worked. I wonder if Apple did this on purpose for some
nefarious reason, or if it was just a mistake that wasn't caught because
they didn't bother to check backwards compatibility.

In any case, it's great to have a solution for Power Mac owners.
