Thank you for your reply, it's a bit disappointing that the two cannot be
used at the same time, but not too bad *IF* it is possible to still swap MMC
cards as required (i.e. treat it like a *very* small CD MP3 player) - I
assume you switch off the player to swap cards?
I have just purchased a 1GB SD card for my PDA, but the largest MMC I have
seen is only 512 - Does anyone know of a 1GB MMC card?

|the Ondio has an internal 128MB memory, which is basically an
|MMC card on a chip, firmly mounted. The control can be
|switched to an external MMC in a slot. SD cards are thicker
|and don't fit into the slot, although the logic which drives
|the card should be capable of SD as well.
|Archos uses these memories mutually exclusive. If an MMC is
|plugged, you don't see the internal any more. For USB
|operation, it certainly has to be like this, because the
|USB<->MMC bridge chip can only talk to one card.
|For Rockbox, it is imaginable to switch at runtime as desired,
|using the two memories like 2 drives. But this is a new
|concept, so far only one HD was supported, don't hold your
|breath for that.
|Rockbox on Ondio will have the voice UI, no reason to drop
|that. Since flash memory has no spinup time/power demand, it
|may even be better with "while hovering".
|Because the transfer is much slower than from disk, I may have
|to change the way the voice file is handled. Right now it is
|completely loaded into the
|mp3 buffer (and has to fit there) when first used, to avoid
|This may be a big latency with MMC, so it's probably better to
|load only the index, and the clip parts later on demand. So
|the voice file can grow as large as you want on Ondio.
