No, the community does not "depend" on it. There is a company that feels
itself a member of this community and has developed an offer everyone can
accept or decline.

Yes. This is no difference to Openmoko, Inc. did since 2007.

For proprietary hardware you have no schematics, no clear identification of
the components, some custom made components without any information,
and no documentation which GPIO is doing what.

Yes. And the PDF is the source. You can run OCR and convert it into any
format you like. And modify it as you like. What else do you expect? More

The Schematics and the component placement chart of the GTA02 - both
as a printable PDF - were sufficient to design the GTA04 board... So it is not
lack of information if nobody is picking up the GTA04 design...

Is this a requirement for FLOSS that you can commit anything directly to the
original repository? Do you have commit access to the master branch of

Anyways, you can make change proposals and there are others who
"sign off" and accept your patches into the master if they fit into the
project goal and fit to some design style and rules.

So if you want something to be changed, please write me an e-mail (in
natural language) with your patches. Or propose it here on this list.

The community can help much better in other areas, e.g. marketing, spreading
the word, software, etc. because high density PCB design needs a very specific
type of knowledge that isn't widely available. And, the PCB must be 100% correct
or even 100.000000%. so it is better to have a very small team.

No. Because you can do it as well.

You can start to learn how to design PCBs, aquire some PCB design tool,
capture or convert the schematics, and make your own layout. Then, find
someone who does production for you.

Because designing such a difficile and miniaturized device is more challenging
than the average hardware hacker is capable to do.

It is possible to design a board for that by the procedure descibed above.

Essentially you are mixing openness and modifiability of source and
compiled binary.

The source in such a hardware project is the schematics (which is
open for the GTA04) and the compiled result is the PCB (which is
not easily modifiable, even with proper tools).

It is like you are asking an open source project to publish compiled
binaries, before you call it "open source". IMHO this is only convenience.

Finally some more technical aspect: it is not easy to just modify the
PCB to fit into an N900 case. You more or less have to redo the whole
PCB layout process (i.e. the compilation), although the Schematics can
be almost the same. So you virtually want to change

	boardc -mgta02 gta04.source


	boardc -mn900 gta04.source

But unfortunately there is no automatic boardc available... It is manual work
eating up several days or even weeks of work...

So everything appears to be available that you can start (including a
community that you can ask for suggestions and help):

What is stopping you from taking the GTA04 schematics and
documentation and run your n900-revival project as described above? 
Money? Courage? Disbelief in the existence of a "market"?
