I'm about to get started on the development of this and I have a couple questions.

Are there any web links for help with Empeg development? I've found this cross compiler:
http://www.empeg.mars.org/devel/software/toolchain.php

Is the hard disk needed or could I store my program in on-board flash? My drive needed a sharp whack to get it going again, I'm not sure how long it's good for. I suspect that I will need some kind of storage device though, and in that case I will use a compactflash or something similar.

Thanks for any help guys, and I'll post progress reports as I go along.
