There has been a lot of discussion on this
subject and I have tried to
read all of it, but I may have missed a discussion of what I think is
the key problem in such a product. Apologies in advance if I am
repeating something.
I think you've got it right--my implementation seeks to simply sample bit
transitions without getting involved in the implementation of the details of IAMs, CRC/ECC--although one would expect
that MFM data is still
MFM data. Hence the need for speed and RAM.
At least data rates are fairly standard--5MHz for MFM, 7.5MHz for 2,7 RLL.

Does anyone know if the connectors on the cables are still obtainable?
