I don't know. The DW records the usual System/3 format -- single-sided;
1 track of FM, and 76 tracks of 256 byte MFM sectors. The filesystem
seems to be tailored to the application--there are lists of pointers to
records with attributes like Document name, date, starting lines, extent
table, formatting data...
There is also an allocation bitmap.
Ring any bells?
