Re: File manager, need someone with an Alpha board

It can also use the frame buffer, without X.

Re: File manager, need someone with an Alpha board

No one? :/
I think this would be a pretty useful file manager for the RPi, because it doesn't need X and stuff, and it has some features mc doesn't.

Re: External (on board) memory

Do the SoCs used for the RPi support external (non PoP) memory?
The RAM is quite cheap now, and if the SoC supports additional external memory, it would be nice to have a C model soon with something around 1Gb of RAM.

Re: External battery

Yeah, would be really nice to get an official answer on how the voltages are obtained (switching or wasting).
