There were several MFm replacement devices years ago, IIRC they were battery

Oddly enough, I've been working on a design for an MFM
drive replacement on and off for a while now. I don't
believe that flash memory is the way to go though with
cheap and plentiful IDE drives available.

I've seen that commercial offering somewhere in Europe
- looks expensive.
