The RX50's are MFM encoded. There's no FM anything on it, unless it's
that way on all MFM diskettes.
Other DEC diskettes may have done this, but RX50's are just higher track
density, but old pre IBM-AT data encoding rate diskettes.
At least on the Rainbow the floppy chip is kept in MFM mode all the
time, unless you've written something to hack it to read alien disks.

You're quite correct--I didn't notice the "RX50" until I'd posted. No,
I was thinking (as probably was the OP) of RX02 double-density.
That was my mistake. I wrote RX50, but I meant RX02.
And, as Chuck pointed out, the MFM data within the sectors is not quite
the same as the MFM encoding used by others.
Sorry about that.
