All these Weazle thingies are just pulse timing samplers plus floppy drive
controllers.
The interpretation of the timing information is separately done in
software, with the hazzle of implementing some kind of software PLL. Been
there, done that with my own Linux software written for a modified version
of the MFM hard disk emulator running on my Beagle Bone White.
The setup is even able to write such images back to disk (I have
successfully used it to create Apple 2 GCR and Amiga MFM disks).
