[Coco] Creating a real floppy from a dsk image over drivewire

[Michael Furman]

I have found myself without a linux pc with a real floppy drive and  
need to create a real floppy disk from a dsk image that I have on my  
Mac.  Is there any way to do this?  I have tried various things like  
playing with the drive on/drive off command in hdb dos, and also  
trying in nitros9 doing backups from /xN to /d0, and also backup f  
blah.dsk /d0 with no luck.

Any hints?
