I think I won't start planning a rev02 until you confirm the basic input/output 
in rev01 works =).

Well, flash then. Anyways, external storage... is there a need for that, or is 
there already flash storage available for keys etc. on the Novena? On the DE0?

Aha, OK. No problem. I guess we don't have any real RF or other data leak 
concerns on these early prototypes...
