Hi again,
Well, yes... I remapped according to what drives I have attached (one 5 1/4" and one 3.5" floppy, and two Horizon HRD's at >1400 and >1600 respectively), the path, the command prompt, and the necessary drive assigns. In any case, as a minimum, I'll have to remap the floppies to the HFDC of course, but I could try without any other changes?
I do have an original TI floppy controller available as well, if that could prove useful somehow; testing etc.
