What is the partitioning scheme for multiple ProDOS partitions?
I *think*  CiderPress can only access a single ProDOS volume on
a physical device. And Windows only maps one partition to a logical
device.

The idea here is to make it easy to store images to the flash memory
on any platform. They all understand FAT. Suppose I write 10 .hdv files
up to 32MB each and 10 .nib files 228K each to the FAT-formated SD card.
The firmware lets the user select one image and maps linear sector addresses
to the physical storage according to FAT.

Same way as Apple emulators use .hdv images on my NTFS drives.
