Thanks for response Jeff,
The floppy controller I am referring to is not an internal CDTV item but the small board I took out of an Amiga external disk drive, you can see it in the pictures just beinh the HxC.
I suppose the first question should be, can the HxC operate two drives (A+B) from a single external floppy drive interface?
Has anyone done this before?
I can see that most HxC users are connecting directly to a machine's internal floppy drive connector, whereas I am connecting to an external disk drive's interface, even though the CDTV does not have an internal floppy drive, just a socket at the back of th machine.
Do you think there is something wrong with my set-up or configuration that would prevent drive B (DF1) from working?
Check if the DS0 & DS1 lines are connected to the HxC !
