Actually, it's 128 bytes decimal, not 80 (you probably meant 80$)  :)  I 
found a reference to a posting by you Robert that mentioned stuffit 
expander ( http://five.pairlist.net/pipermail/coco/2004-January/003346.html)

The best way to see if the disk format is OK, after modifying the file 
is to load it with the MESS wimgtool .
