In reality, the question has nothing to do with RLL or MFM encoding, it
has to do with whether or not the OS supports a particular type of
controller.  The OS needs to know a lot of information about a disk
controller, including where it's registers are located in the memory
map, what interrupt it is using, formats of the Command/Status
Register, what DMA channel if applicable, etc.

Esix publishes a list of hardware they are compatible with; get a copy
of the list.  If your disk controller isn't on there, find out if any
that ARE on the list work with your drives and buy a new disk
controller, or find out if another V/386 supports your disk controller
and buy it instead (this will probably be more expensive than replacing
the disk controller).

My opinions, your screen.                                   is much better than
Raxco had nothing to do with this!                        the best day at work.
