It appears that the format used by the Rainbow disk controller is not
compatible with the format used by the controller in the MVII :-(

It looks likely you will have to run something on the Rainbow itself to do
this unless it is possible to extract the disk controller from the Rainbow
and put it into something else that can cope with it.
