Heading says it all. I have a Spectrum +3 (with +3e ROMs if that makes any difference) with a DivMMC SD card interface.

This works fine in +3e mode, but as I like to use the +3 with CP/M plus (Original Amstrad/Locomotive) are there any CP/M drivers available to use the DivMMC as a drive C:?

Or are there any technical reasons why this wouldn't be possible?

This video (no longer present) seems to imply it's possible with a DivIDE, at least. Unfortunately, there is no further explanation on that.
