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).
This is where I wish we had teleportation--I've got stacks of various
old ST506-interface controllers and drives. One I don't have is an
ARLL Perstor controller--that might be interesting.
Phil, what are you using for your sample rate? I'm thinking that
30MHz might be adequate for the job, since hard drives don't seem to
have the ISV issues that floppies do.
