Yeah, I suppose there are a few more details in the mix worth mentioning... I'll have to write something up later (when I can go back over the notes).  But I will note that we were using The Inspector to grab the track nibble images, then sending those as files saved on regular disks.  Via ADT 1.2.2.  Which had a bug in sending images.... an so on.  Great fun.  Advanced Demuffin was used once the RWTS was isolated.  Should have converted nice and slick.  Except Advanced Demuffin had a bug in it (I posted on that a while ago).  But hey, after we got the tool chain debugged and working, it was fast!  I'll post something later.
