[Coco] 720kb Diskettes

[Ed Orbea]

   I'm finally getting around to accessing via my SDC) the Australian OS9
   POD library files graciously provided by Bob Devries in Feb 2015 (yeah,
   I know it's taken me a year).
   Bob says that they are 720k diskettes and I am having problems getting
   dmode properly set (either in VCC or SDC) to access the drives.
   Whatever I try just gives error 249.
   Can I get a  listing of the proper dmode settings?
   Thanks
   Ed
