Flashboard questions...

Hello, I'm new to the Jornada scene.

I haven't been able to find a picture of a stock Rom board.  Is it identical to the flash board except for the fact it has rom on it?

I can't belive there is not a way to interface (Hack it.  Look up zipit in google! Also if someone can add a IDE cd-rom to a gameboy they should be able to do this....) a compact flash card (or SD card or even something else) to the rom board.  Even if you must remove the origional rom and put the new memory in its place I would think that viable. Interfacing removable media like SD or CF would also solve the flashing problems...

Let me know if I'm way off base here...
