 nooOo - anyone is still free to create open hardware projects, either CPU
Cards or I/O Boards, at any time.  we cannot however base a $NNBn business
on the hope - the hope - that someone *might* come along and create such a
CPU Card.  or that i (personally, who really WANTS there to exist an
open-licensed EOMA-68 CPU Card) personally *might* have the time and skill
to create a open-licensed EOMA-68 CPU Card using e.g. kicad.

from what i can gather, it's simply that wits-tech is the company that
allwinner chose to design their EVB.

mmm... i don't know that that's true.   what we do know is that every x86
laptop product they've produced has been too expensive for export, but that
that hasn't really mattered because their laptops are only bought
*internally* inside the PRC via "Govt Channels", where the *actual* price
really doesn't actually matter, it's all "funny-munny" so to speak.

when we asked them what their goals were they said "to not lose too much
money and to keep everyone employed" which is shockingly hilarious given
the scale they're operating on.  luckily they have many many different
departments, some of which are massively profitable so they can absorb
these kinds of things, but not forever!

so... we can't *actually* say that they are "price-orientated".  we do know
that their absolute top priority is to keep everyone employed.
profit-maximisation is definitely a secondary consideration for them.

do you have any rendering or picture of the device you can show?
no - we're still waiting for them to supply the samples that need to be
converted.  ok, we've been screaming at them, if i'm honest, given the
short timescales.  i'm told that they're ready, and i'm told that an AOC
screen has been used (i am *guessing* it's a 1280x800) but i won't know
until we receive the samples some time in the next few days.

i'm thinking of asking the ODM to add a daughterboard for dealing with
different LCD panels, just in case.

we'll see.

ok gotta go.
