That way, a system that could handle 1:1 interleave would get one version 
of sector 3, while one that could not handle 1:1 interleave would get the 
other one, and you could have different code for the two kinds of 
machines.    :-)

But, that has 11 sectors on the track
Were they 512 bytes each?
Was it 8"? 5.25"?  SD?, DD?, "HD"?
