OK I agree on not betting money into this yet. We need some serious planning, I deem it best for alberthrocks to do that. Just let one person do that, this prevents the project to eventually break down. I hope alberthrocks can confirm he will do that? or maybe he can appoint somebody else, as long as there are no more then 2 people max working on it we should be fine. This person (or persons) could then output their ideas to the community and the community can give feedback and new ideas, once the design and harware design is decided the community can more actively involve into this.
Remember that building this can take years, I estimate it about 1 or 2 before we actually get to a point where there is something sellable available. I do not intend to be pessimistic but I think we should al consider the huge effort and time this takes.
now I will await a confirmation that alberthrocks or somebody else will do the planning, until then 9and after it) we can still spit ideas here...
I pretty much ask everyone to be patient with this, it is quite a undertaking and not something to be taken lightly.
Once somebody has the lead over all this we can then move further along side the directions given by that person.

Keep in mind that Linux is programmed in C, so z80 isn't the best option. (compilers are not very good for z80)
Aah true, forgot about that. Maybe a PIC( http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=2607) is more flexible then? MicroChip has some pretty good ones. Maybe we could even have a dedicated GPU? (seeing that Micrcontrollers aren't that expensive). It adds to complexity though. Does anybody know any good 16/32b C compatible microprocessors? I honestly don't altough I bet the intels I referred would work... Edit: I think the PIC32 (MCU) has all that is needed and it is quite cheap, around $30 if I recall it properly but ocne again I have no clue whether all the C-specific content can run on that...You'd pretty much have to hard-code all C operations and libraries and do-i-know-what into it which is extremely tedious and error prone.

Aye, altough I'd prefer to take a siderole. I am willing to invest a little, it really depends. Also I have alot of other projects running in parallel so well, yea I am not constantly available. We need people like BenRyves and KermMartian though, and we need their time :p
I think we should first maybe produce a dozen devices maybe more, maybe less.
As for importance:
Color: 8
Mouse: 7 (if it's going to be a linux driven system then it might be useful, adding a PS2 port isn't that hard (or we could go usb))
Keyboard: 9 (allows for greater productivity, if used wisely often faster then a mouse and if there is a PS2 port already...)
Math: 6 (important but not a must)
Speed: 10 (speed allows for great creativity AND, you know 1+1=2 faster then the other folks cheating the test)
LCD Resolution: QVGA or VGA (respectively: 320x240, 640x480) I don't really care that much, if it raises the price to much I deem QVGA enough. If we are going to have a (multiple) window based GUI then 640x480 is pretty much a must.
Color Depth: 8 bit (pretty high quality, if it affects speed to much the take 4 bits)

if anyone will gie me something to read about the chips and stiff for making it that would be great.
this is a vast resource about digital electronics. It contains pretty much everything you need to knwo except how to solder. It teaches all the theory. ( http://www.asic-world.com/digital/tutorial.html)

Very intresting project, altough it is all just specualting now. Reminds me of the Pandora  . Well anyway altough I am really just starting with all this kind of stuff I do know something about processors and circuits. If anybody is going to take this seriously then you ahve to start to decide what kind of processor 'we' will use. I think a 32 bit processor should be more then enough, 16-bit might do the job as well. Some good 16 bit processors are: INTEL 8088 @~7.2 MHZ INTEL 80188 @~18.72 MHZ Some good 32-bit processors (and not to expensive) are: INTEL 80386 ranging from 16 to 33 MHZ INTEL 80486 ranging from 25 to 100 MHZ. Altough clockspeed isn't everything I suggest at least 50 or more MHZ. Another focus point would be a (G)LCD with a high refresh rate so we can use the processor at full speed when writing to or reading from the screen. Another Idea I had but which I am not sure about is practical is having several Z80's. The reason to choose Z80's in the first place is because this whole calculator community is familiar with it and we want to develop for this community right? Ease of use is a second. My last suggestion would be the most updated version of the Z80, the eZ80 ( http://en.wikipedia.org/wiki/Zilog_eZ80). Being 9as wikipedia says) 4x as fast as a regular Z80 it might be enough. Frankly what I need to know is how resource intensive the final OS (linux) will be, based on that decide the processor and based on the processor decide the other hardware. So what is going to be this things purpose? Is it going to be a gaming device with some math capabilities or is it going to be a hybrid? Shortly siad, what do we want it to be capable of? Maybe everyone should make a wishlist?

ENIGMA is freakin' awesome! Altough it's just too late for me, I dived in the XNA pool, very steep and deep

Because the Chameleon'd TI-73 was donated.
Don't forget, we are calc programmers.
We r brokeded.
Tell that to the people who purchase nspires for the sake of games and not programming 
Hey! I never said I didn't want to program it ! and secondly there are quite a few calculator experts around that do have more then three or four calcs. I think I am quite humble with just two (Ti84+ and Nspire (still being send)) sorry for being off topic but I had to reply to that to avoid misconceptions of, especialy, myself.

Many thanks all. I have ordered mine now. However until it arrives I want to get to know the device trhough this emulator, but since its in french I don't really understand what to do....  could anybody very roughly translate? I have tried google translate but that gives garbage... the description of this video:

I have been tinkering quite a while now about getting a Nspire. Seeing all the amazing stuff Ndless can do with it plus it being programmable in C makes me feel I have to. However since using Ndless on this thing will be my main use what is the best Nspire I can get(not neccesarily the fastest)?
Nspire Clickpad (blue)
Nspire CAS Clickpad (light-grey)
Nspire Touchpad (dark-blue)
Nspire CAS Touchpad (black)
I seem to recall the CAS versions were not compatible with Ndless? Or is my memory playing tricks on me?
Thanks for the advice in advance! Remember I WON'T be using it for math purposes just for development and gaming (how seriously can you take gaming?)
P.s abot gaming, gaming I really mean GAMING, like a game...
Darn I just lost
but,
so did you.

Basically we are seeing Ti being very very undescriptive. Err: Version wouldn't make you guess that the header of a group was split over 2 Flash pages wouldn't it? Err: Flash or Err: Header or Err: Boundary would have been better. Secondly it indeed shows Ti being lazy about getting the header always in the right place, makes me wonder if data actually is at all neatly packed of any prm or app in flash rom. Would there be FF's between several apps? that would indicate that Ti is even more lazy then I initialy thought. Does make something as rudimentary as a garbage collector needed though.

As far as 3D stuff goes, I at first voted mode7 but then revoted for polygons. I think polygons can be done if you don't have too many at the same time. I think it is just awesome if we could work with them! I can already imagine a on-calc model creator-viewer that stores models into appvars. I guess using the OP registers for the vertices would be the fastest?
mode7 has my second vote if there is such a thing. In terms of speed I still do recon it faster then poly's but it is 'less 3D' then the poly's.
Now here I am just gonna suggest something that is maybe out of bounds but I'll say it anyway. How about a combined mode7 and poly's? can you imagine a character (poly) walking around in a mode7 world? All the structures and trees would be poly's but the basic ground texture could easily be a mode7 'texture"
I am really looking forward to this!
On a side note I personally would like different tokens for Axe then for basic, but that is just me having hard times switching between the two.

Cool Units! I can't promise anything but I think I should be able to finish the Xaos before the end of this week.
