Re: Extracting files off “unknown” 8 inch disks. Any thoughts…

[Jerry Weiss]

I stand corrected.  It appears that the handwritten label has a ODS1 style numerical UIC.

The printed directory may not actually be from the floppy media itself.  It is
hierarchical.   So perhaps it is from some ODS2 media that is holding the files 
that are being transferred to/from the Floppy.
