Just for reference, should I or anyone else care to use it, would you
like to document what they are (or point us to where we might find it on
the web).

Mine.  I've tried and tried again the read ADFS 3 1/2" disks formatted
to ADFS 640K formats and it just doesn't work.  I can, however,
successfully read and write 720K disks on both BBC and PC and transfer
data between to two.

of the filename.
