IMHO, I'd be quite happy if it simply created a single big file eating all
of the free space (or some - asking on format how much to grab) the on the
card and presented that to the Newton as a block of storage. I wouldn't
worry about trying to read the rest of the card. (i.e. a "file" on the
flash card would be equivalent to the Newt as an entire linear flash
card.)

If you want to make it fancy, you could have the file grow as the Newt
allocates more space on the card. But that's not critical.

You could then use your PowerBook (or anything else capable of reading ATA
Flash / Compact Flash) to simply backup your newt. It would also be much
faster than NCU/NBU - though it wouldn't get the internal store.

Compact Flash is certainly cheap enough to not bother sharing it with
other devices, but it would be convenient to allow other devices to read
the virtual linear flash "card" file for backup.

Eventually someone could figure out how the soups are stored and write
transfer programs, but getting an ATA driver in place is more important.
:)

That would certainly be a great start.

So the real question is who has the docs needed for this? i.e. docs on
how to write a Newton driver.
