Hi
 As was mentioned, not all controllers do single density. MFM double
density is no problem. There are a number of programs out there
that handle differing sector counts and sector sizes. You could
also write your own. You'd need to know how to setup the DMA and
the floppy registers. It isn't real hard but it is easiest if
you have some examples.

 If your disk are single density and you have a controller that
handles single density then you are OK. Intel's double density
was M2FM and not MFM, for the 8 inch disk. About the only way
to read this was with an Intel M2FM controller. As far as
I know, these only existed on multibus boards.
