The MOOF format was developed by John K. Morris as a way to store the data coming from low-level disk reading hardware, such as the Applesauce. It's essentially a minor modification of his WOZ v2.1 format that emphasizes support for the Macintosh instead of the Apple II.
Differences from WOZ:
- Some of the fields in the INFO chunk are different, or have different interpretations. For example, the Disk Type field drops 140KB GCR floppies and adds 1.4MB MFM disks.
- The set of standard fields in the META chunk is different. Fields whose meaning changed
were given different names, e.g.
side_namevs.disk_name, avoiding ambiguity. - The bit data may be MFM instead of GCR.
For additional commentary, please refer to the WOZ notes.
