It definately works with BASIC also.  In it's simplest form, you merely 
DISKINI for 160kb.  Of course, with ADOS, you can get the full 720kb, 
but noone has ever shown me how you can copy an application from a 160kb 
disk when all your drives must be the same size, as required in ADOS. 
 Check the latter volumes of CFDM (sorry, I don't have the URL handy) 
where I wrote about both the genesis of the Grizzly CoCo, which used 3 
built-in 3.5" drives for both OS9 and BASIC, and the conversion to 3.5" 
drives.  They are under the column "The Hardware Store".  Oh, yes, at 
one time I was running a system which had a SS/DD drive, a DS/DD drive 
and a 3.5"  720k drive tied together.  They not only worked fine in 
BASIC, but I could also change the default drive by menu under OS9.
