The only way I could find to do it was to use DOS routines to read absolute
sectors off of the disk.  A real pain.  I had to write an assembly language
routine to allow me to invoke an arbitrary interrupt and to pass register
values back and forth.  My PC doesn't talk to this machine yet, so I can't
give you the sources here.

I started with reading sector zero to find out how the disk is
layed out.  I recommend Norton's Programmer's Guide as a good reference.
Good luck.
