   Does it fail
to see any sectors at all?  
 Correct. I haven't tried a catweasel on it yet to see
 what the details of the sectors are. 
Then most likely there is some other factor in the 8-sector format
which makes it incompatible with the PC disk controller...

Seems odd - if other formats commonly used on this machine use
standard enough encoding, headers and marks for a PC controller
to read, I wonder why they went with a different format for the
8-sector variety. Is the 8-sector type older? (ie: perhaps the
changed to a more standard format somewhere along the way?)
