So what is needed to get the MS-FST to work with a CTI FDC-10 disk controller
card?  This is the controller card which allows the use of IBM-PC disk drives
on an appleII.  The ROM on the FDC-10 contains routines for reading and
writing raw data to the disk and also routines to read and write Prodos
blocks.  What kind of interface does the FST expect?  Is this documented
anywhere?   (I do not have a GS only a IIe so I do not expect to use this on
my current machine).  Also how does the OS decide which FST to use for a 
given disk,  does the application software have to tell it what to use or
is this transparent?
