Yes.
The ST506 adapters have been prototyped on padboard (using my trusty
Roadrunner pen), but I don't have a finished PCB design yet. That's on
my "Stuff to do in my copious spare time" list.
I have got proof of concept code to decode data written by a Western
Digital 10xx MFM controller. Other MFM coding schemes probably won't be
much harder to implement, but I have no other controllers to test with
(just a WD100x of some description, and I don't even have the manual or
low-level format utility).
I do have a Seagate controller card, but that's RLL (and I haven't got
the drive -- it's in a machine at my father's house -- again, "copious
spare time")
