This is _very_ interesting finding. I wasn't expecting that the Ondio is
derived from our recorder hardware.

Your experiment shows that the hardware must be very similar, including the
LCD connection. Are there any pictures of a dissected Ondio available

So very likely we could port Rockbox to it, for the sporty folks who have
trouble with a disk player. Although it's a bit overpowered for a device
that can hold only 2 albums.
The good part is that the NAND flashes are all alike, since they have a
8-bit parallel interface instead of a data and address bus. So the internal
memory could perhaps be upgraded .

Rockbox will have to at least learn some new tricks like:
- NAND flash driver (very likely to be used, if no CF card inside)
- FAT16 (we're likely to find that being used)
- MMC driver (for the expansion, can be done later)

Now where do I get an Ondio?
