Tim,

Using two floppy controllers would be the same as using the CoCoSDC & a
FDC.  You would probably have to write your own routines to switch the MPI
slot for the I/O lines.  Not sure how Disk Basic would handle.

As far as NitrOS-9 goes that is something I think might need to be updated
with the disk driver and maybe have a value some place in the descriptor to
specify which MPI slot the drive is connected through.

Personally, I think this is something that should have been done many years
ago.  It would have been nice to be able to use multiple controllers for
use with multiple drives.

Now this is something I find interesting.  Could one set the SDC for the Dragon addressing 
and then use both the SDC and a standard COCO with real disks on it?  Assuming one made
custom drivers for NitrOS9 for the SDC.  Hmmm...  What about a custom version of HDB-DOS
that was aware of both?  So many ideas, so little time.

At least I am making headway with my floppy project.
