Really what you should seek is either full emulation in an MFM card or a PCI compliant MFM adapter.

If you could hook up your MFM drive to a more modern system this would solve a lot of your problems.
Extracting data being the goal, you mount the drive in any OS you want... linux perhaps.. and get the data off onto that PC's local storage or over the network or to USB..etc.

This has been done by the way...

Since "gulgul2006" has brought back to life this discussion started by "Bob in Wisconsin" back in February 2011...

Bob started this discussion because he wanted a solid state replacement for the aging Quantum Q540 connected to his CompuPro 816 system. The easiest way to do that now (which didn't exist back in 2011) is to use the DREM MFM drive emulator - it can easily be configured to emulate the Q540's geometry, and directly supports the drive format generated by the CompuPro Disk3 MFM drive controller. The only setup required is to create an blank file on the DREM's SD card equivalent in size to the formatted capacity of the Q540, and to modify a configuration file on the same SD card to specify "CompuPro Disk3 format" - from that point, it is "plug and play". See https://www.drem.info/
