[Tiptoi] Information sharing about Tiptoi hardware (was: ein bischen Fund)

Hi,

I am the guy who worked on the hardware. :-) Unfortunately I couldn't 
spend in the last months so much time into TipToi investigations.

>/  And how it is known that ZC3202N is an ARM processor?/

That the ZC3202N integrates an ARM926EJ-S is highly probable because 
Anyka uses it for related products, like the AK10 
(http://www.anyka.com/en/productInfo.aspx?id=101).
A disassembly of a small portion of the firmware binary supports this 
understanding.

At least some of the GMEs (for example Leserabe "Im Garten der Feen") 
contain binary code for ZC3201 (seems to be the predecessor of the 
ZC3202N) and ZC3202N.
(in this context you may want to have also a look into 
https://github.com/webforge-labs/psc-cms-js/tree/master/tests/files/tiptoi)

Anyway, within the last days I did some measurements with my 
oscilloscope and found some new details. These are not breaking news but 
nevertheless I like to share this information with you.
This is information is text but also screenshots. Besides of this, we 
have hardware related information Matthias found out already some months 
ago. I think also this should be made more available.

What tool should we use for sharing? Github is of course great for 
source code but for documentation with attached graphics etc. it's just 
not the right tool. Sharing by mailing list is also not the best 
solution for future reference.
In my opinion, a Wiki could be ideal for this purpose because it's much 
more accessible and easier to use than Github.

What do you think? Maybe someone has already experience with setting up 
a Wiki or has another idea?

Regards,
Björn

There are some ARM binaries attached to some of the data files.
It isn't sure what purpose they have yet.
