  As far as I know, they ONLY worked with 8-inch drives.
The one I used
 only did FM (single density).  It's perhaps possible that they might have
 later offered an MFM (double density) version, although such a controller
 would have been rather more complicated.  On an 8-inch MFM disk, you 
I stand corrected.
SVA told me (at Comdex one year) about an MFM project, but I never saw a
result.
Could you cable it to a "1.2M" drive and run a "high density" (~250K)
FM
5.25?  (77 track, 250K data transfer rate, etc.)
