I concur with untwisting. The PC modification to the standard floppy 
cable does more than just swap drive IDs (though I can't remember enough 
of the shugart interface spec. to say what). Use an untwisted cable and 
try to set the drive IDs to 0 and 1 (being PC floppies, they'll be A: 
and B: which won't map directly to :0 and :1 or something equally 
irritating done to make it harder for the unqualified to break something).

Last time I tried connecting a PC floppy drive to a Master, I got 
precisely no results.. even with a single drive. So it might be a case 
of changing more jumpers than just the drive ID.
