I keep meaning to test that.  I have all the bits (Zoomfloppy, on
Linux, and multiple D9060 and D9090 drives).  I haven't yet gotten my
Zoomfloppy working with my 2031, so that's the sticking point there.
I should check the firmware version.  It works perfectly with a 1541
or 1571.

I would say that depends on how deep you want the docs to go.  CBM DOS
3.0 and the block structure are documented.  The standard read/write
commands all work like all the floppy drives, but there is one unit
("0:", like a 1541 or 2031) and a larger amount of sectors per track
and tracks than a floppy, but ultimately, very much like a large
floppy with the directory at the front not the middle.

What's less well documented is internals and how the "DOS board" talks
SASI to the Xebec SASI<->MFM bridge.  Some stuff is known from
disassembling the DOS board ROMs, but not as well understood as, say,
the 1541.

For writing an application to grab directory blocks and read the
allocation map and read files, all of the necessary things are
