Here’s my first post, inside the 2Wire 2071A Bigpond Gateway, I think this modem is about 2-3 years old. No screws to unscrew this modem, so I just took a dermal to it and opened it up (not like it was working anyway).
1. 2Wire Perseus Chip
We remove the sticker and we can see this chip.

This looks to be a 128 Mbit NAND. PDF

3. Nanya Memory
Looks to be 16 Mbit of memory. PDF

4. Metal cover removed
Nothing much to see here
And that’s it, we’re done. I didn’t expect to see a large NAND or Memory on this device. If anyone wants to comment on this or let me and others know how it all works, etc feel free to do so 
Great coverage! Nice to see blogs like this
