It was my impression that the only ESDI drives in the line were the really
big ones (the 70 and 115Mb disks available on the Models 60 and 80).  I
thought the regular drives (the one built in to the Model 50 and the 44Mb
drives on the 60 and 80) were the same old stuff.  Of course they all run
at a 1:1 interleave, so is that a hint?
