I'm no expert on the workings of floppys & drive selection. I believe
though, that the twist in a PC cable forces the drive to drive 0 (zero)
from drive 1 (default). Therefore, connecting a floppy connector to the
end of a twin BBC cable (no need to remove the BBC flat edge connector)
leaves the 3.5" drive as drive one (as there is no twist in the BBC cable).

At least that's how mine seems to function.

Cheers,
