What I interpret what you said above to mean is that
the interface between
the controller card and the ST-412 drive is not simply a digital
interface. It is acutally the MFM stream bi-directionally, and that the
controller is what converts this to the system required digital stream,
and the systems digital stream to the MFM stream.
Is this essentially correct?
As long as the signal meets a few constraints, the drive doesn't care what
the signal is. Think of the ST506 as a big fast floppy drive. Except for
buffered seek, pretty much dumb as a stump.
