Hi all,
Hope you can help me solving this problem..
I bought a TI-nspire CAS+ on eBay, but it seems it can't be detected by the student software. All the stuff about maths and calculus are working on the palmare, so I really don't know what's the matter.
I recently discovered the existence of prototypes on eBay, not able to share documents with PCs. Two questions for you:
1) How can I know if mine is a prototype? (Even though I have a bad feeling about this.. >:()
2) Is there a way (hacking or something like that) that allows me to share documents using the software?
Last thing: I don't even know if all I'm asking is legal or not, even the possession of the prototype (that's supposed to not be sold, right?). Please let this newbie know if he's asking or doing somethin stupid.
-
The nspire CAS+ were the prototypes, yes. But I'm almost sure it's legal to possess one.
I don't know much about the CAS+, but others here have experimented with hacking or updating it.
-
Thanks for your answer.
The problem is I can't update it, since it can't be detected by PC. Manual reset isn't an option either, I think it will just screw up the whole thing.
Any other suggestions or hacking experiences?
-
The newest student software probably wouldn't work with it. Have you tried TiLP?
-
Not yet. I'll let you know if something magic happens.
-
TiLP won't work with a CAS+.
You need an old TI-Nspire Computer Link Version: 1.0.59
http://tiplanet.org/forum/archives_voir.php?id=1439
It has an update menu, but it's totally useless as no CAS+ OS has ever been released publicly by TI, and no CAS+ ROM has ever been dumped up to now.
You won't be able to update and have to stay with that awfull 1.0 OS.
Hope it wasn't expensive...
-
True, no device detected by TILP. Just experienced.
I'm not very interested in staying with the old OS, i just need to share files between the calculator and pc. Is it possible?
Anyway, not so expensive..

*Update*
The TI-Nspire computer link doesn't recognize the palmare as well.. :(
-
I'm not very interested in staying with the old OS, i just need to share files between the calculator and pc. Is it possible?
Yes, but only files generated with a TI-Nspire CAS+ handheld/software.
Meaning that you won't be able to open 99% of TI-Nspire files available on the Internet.
You should contact TI-Cares and see if they can do something for you.
You've bought an unfinished prototype which is "not for sale" as written on the back.
-
Has Ndless been created for that OS by the way? Of course new Ndless programs were created for newer versions, though, but I'm just wondering in case.
But yeah it's best to be careful on Ebay to make sure the calculator your are buying is not a prototype. Also be careful, because there are prototypes called TI-Nspire on Ebay that are passed to buyers as commercial models to trick people into buying them.

Apart the fact from discovering that TI-Nspire CAS+ & TI-Phoenix were the same thing, nothing interesting has been achieved on those models yet.
No flashing, no dumping, and no ndlessing... :(

I wish sellers like those have their balls fired up on a barbecue.
Well anyway, 30 euros for a CAS calculator isn't too bad, it could be gone worst. :)

Yes, but only files generated with a TI-Nspire CAS+ handheld/software.
As I said before, that software doesn't work anyway. No palmare found.
I'm on a VMWare machine, running xp. Could it be the problem? :|
-
did you download the version at the link he gave you? It's an older one, specifically for your calculator.
With VMWare, you have to make sure you set up the USB correctly. Do you have other USB devices working properly?
-
Yes to both questions, software downloaded and installed, and all usb devices working great.
-

You could possibly send this fun calc to critor for analysis... ;)
But yeah, you're pretty much SOL... Amazon I would trust more. A friend got an old Clickpad CAS for ~$50. (And it's not a prototype - he install ndless3 on it as soon as he got it! :D)
If you do decide to ship it to critor, he will likely pay the shipping for you, and maybe (tentatively :P) give you money for a new one :P
-
Well, as a calc it should run just fine.
Why do you need to transfer files to and from the pc? There's not much to do with them once they're there, and there aren't any I'm aware of that you would send to the calc.

TI Cares answered this morning:
"Dear Customer,
Thank you for contacting Texas Instruments.
By looking at the provided serial number and the name of your model i can verify that you have a prototype calculator. Unfortunately this means that there's no way of enabling connectivity to transfer files or update the operating system. I'm sorry for the inconvenience and if you should have any further questions, please don't hesitate to contact me again. Thank you and have a nice day!"
Seems I should resign. :(

I have some files by a friend's Texas Calculator that I would like to have on mine.
*UPDATE*
I did it!
On XP, the TI-Nspire was recognized as unknown driver, so I just update the calc's driver following these (http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetId=85964) steps.
Now, that linking software posted before is working properly and I'm able to put stuff on and from the calculator.
Thank you so much everybody! :D

According to the eBay photo, it's one of the CAS+ prototypes that were massively evaluated in schools in 2006-2007.
I don't need this calculator - it's nothing like rare.

Wrong, connectivity to transfer CAS+ files works perfectly with the software I linked you.
When I say TI-Cares is not accurate and doesn't know what they are speaking of...
Last year, TI-Cares answered that for 80$, they could exchange you the prototype for a production model.
You should ask them about that.

If it's not a CAS+ calculator, there is currently no way, more than 5 years after the CAS+ evaluation.
And it's unlikely that there will be such a possibility in the near future.

You see that TI-Cares was wrong! :P
-
Just like critor says, no files can be read by the TI-Nspire, even if they are .tns themselves. It can read files only generated on the calc.
That's pretty bad.. :/

You serious? I'll give it a try as soon as possible. I'll let you know the answer (but I'm no optimistic).
-
A solution can probably be found after we've been able to dump the CAS+ Boot1 / Boot2 / OS.
But as far as we could try, the CAS+ seemed to be pretty well protected, and only a harware-dumping method seemed to be possible without knowing more on the OS.
-
Ok, so I'll try to be in touch with news about dumping this 1.0 OS..
If TI Cares answers, I'll let you know.
-
I have a thought: Does anyone have any CAS+ .tns files? Inside they're just xml files on the older ones, and maybe a converter for CAS+ files to newer formats could be managed.
-
Now that's a good idea. ALso it would be handy for those who got other OSes as well. I remember Lua games made for OS 3.0.1 using third-party tools didn't work on OS 3.0.2 for example and I think some old documents didn't open in newer OSes or vice-versa even if sometimes they didn't use any new feature.

If it can be helpful, i can create a file on the CAS+ and send it to you. so you can handle it. I'm quite new in this kind of things.
-
If those calc's are not for sale, how does TI dump them on the market? Don't you just love the way TI sets up unsuspecting customers for a bummer!
-

Yeah, really a good question..
-

TI gave many to shop's and schools to test, and they put them on sale. But TI should have done something so this situation could not be possible.
-
Yeah the issue was mainly TI trusting teachers and some employees too much and those finally decided to make money off the calcs, fooling people in the process.
-
Not only "some" teachers, DJ_O.
Depening upon the school, the CAS+ weren't lent to the teacher, but to the students who could take them home and everything.
-
I would like to see a CAS+ file, it might be interesting to see what's different. I would think that notes, at the very least, would convert fairly easily. Programs have a good shot too, since AFAIK TI hasn't removed any commands, just added some, and they're probably stored as plain text. Other parts, though, could e completely different. Who knows, maybe they completely redesigned the spreadsheet application.
-
I appreciate your disposability, here are a couple of files created on the CAS+, a notes and a calc file.
http://www.mediafire.com/?911ctvc748mdnl3
http://www.mediafire.com/?hhd71w3bdllw157
Let me know if you need some additional information or other kind of files. :)
-
Cool.
Okay, so first impressions: The XML for the calculator app is fairly readable. (See Problem1.xml) (Oddly, it's called the scratchpad, which is a feature all its own in later OSes.)
*you entered 7*8, then 87*84, then [[8][a]]. It also contains info stating whether each answer is in degrees or rads, complex numbers or real, and something that "comp" stands for.
For the note one, you wrote "i know a mouse and it hasn&'t got a house,i dunno why i called him gerald." It's got the basic html-style symbol replacement ie &
Document.xml is less readable, but short enough to be deciphered easily. It's a bunch of numbers representing settings. I think that this file was the same between both tns files.
All in all: It's extremely similar to the specifications for the 1.1 OS, no great surprise there. Converting by hand would require the least startup work, and isn't terribly difficult.
Critor should know this one: Does the file converter work for sending 1.1 files to 3.1? I remember there being one when they switched to the encrypted filetypes.
-
Thank you very much for your effort, let's see if critor can give me some hopes.. :)
-
I can take a look at it; maybe I can make nCreator (http://tiplanet.org/forum/viewtopic.php?p=121171) create CAS+ supported documents.
I've done quite some work with the Nspire XML the last month's so that I think I'm up to the challenge :)

It would be awesome..
-
Okay, the XML is incredibly similar (quite normal actually) to what we have now (In 3.1).
improponibile, can you make some other notes pages with bold, italic, multiple lines of text and other stuff (If CAS+ can even do that).
This extra information will help me a lot :)
Thanks
-
Here we go:
multiple lines (http://www.mediafire.com/?9fdkxqx2g1nnpi9)
bold (http://www.mediafire.com/?zj727mb897sa7as)
italic (http://www.mediafire.com/?ner00nsi6fu9wxa)
underline (http://www.mediafire.com/?gv2xapu0hr3k6xu)
superscript (http://www.mediafire.com/?5j24sh0psyuhhsj)
subscript (http://www.mediafire.com/?gscfayibvoh6b4r)
Please let me know if you need some other stuff. :)
-
Wow, this is great. What turned out to be a purchase on Ebay unintentionally of a nspire CAS+ gives us the opportunity to delve into TI's early progress with the TI-nspire.
We might be able to develop special tools/programs for the Nspire CAS+.
-
The last notes and scratchpad documents work fine on 3.1 (recompiling the tns with Luna).
So, if you want to see your documents on the computer, you can do this:
1) Install Luna
2) Change the file extension of the TNS file to "zip"
3) Take the Problem1.xml out of it, and run it through Lune like this: "luna Problem1.xml mynewdoc.tns"
4) Go to the online document player of TI (http://education.ti.com/calculators/products/US/document-player/) and select mynewdoc.tns.
You should now be looking at your document :)
-
nCreator looks nice and promising. If it could support documents for every single TI-Nspire OSes and allows converting between OSes it would really be great for the TI community, especially for students.
-
Yup, here are still many things that we are going to improve it with :)
Right now it even supports more colors than what you can do using the official software :D

Works like a charm, nice job!
Files cannot be modified on the document player, uh?
-
Glad it works :)
Files can not be edited in there, but I might make that nCreator supports cas+.
(The document player and nCreator are two different things)
-
That would be nice. ;D
Yeah I know they are different, I'm a newbie but I can tell what's an online reader or a generic software. :)
Waiting for your news, buddy. Then you can decide where I can put your statue.
-
I have a question for you : does the file you generated work on your cas+? Probably not, but interesting to try :D
-
You mean, the mynewdoc.tns one?
No, it doesn't, it says "not supported". But that was predictable.
-
Ok, thanks.
I'll see to give you some documents to test soon.
Edit:
Can you try the attached TNS file?
Edit2:
Oops, error in file :P Re-uploaded
-
File can be read. You did it! :thumbsup:
Where's the magic?
-
Well, I was lucky that they did not yet add a special header to the TNS files :)
Anyway, here is another file that you can test.
-
That is not supported.
-
Can you try these?
-
Only test3 is readable, test2 not supported.
-
Okay, that means that it only supports RTF based styling and not the XML based one that the newer versions support.
nCreator doesn't support RTF, but I think it's not ttoo hard to implement :)
-
So, how did you create the test3 file? You just wrote it in .rtf and converted it?
-
No, I converted the xml output from nCreator to RTF by hand.
-
Ok, I'm not familiar with this but I can understand.
I just discovered nCreator, so that is an online player as well.. Didn't know it.. :-\
I just need for it to support .rtf? Ok, in the meantime I'll try to work on converting stuff. ;D
-
I think I'm making you a bit confused here :P
nCreator is a program to make documents online. You cannot open exisiting TNS files. nCreator is made by me and TI-Planet.
The document player is made by TI, and only shows the content of it (you cannot edit).
The rtf is quite different then the normal rtf, and you need to do many other stuff before you can make a tns file of it.
-
Yeah I saw that nCreator had not an "Open file" in it. So the TI item is just a reader, while your work can create a tns file. Hope to have understood now.. :/
Guess I can't be of any help, just waiting for you to fix things.
-
I don't know what's going to happen now, now that jimbauwens has left...
Sorry I personally can't be of much help...
-
Actually I'm waiting for him to find a way to implement nCreator with rtf files..
Let's see how things go on.
-
I don't know what's going to happen now, now that jimbauwens has left...
Sorry I personally can't be of much help...
It probably depends, as he'll most likely be around on certain IRC channels not in Omni territories or in direct contat with TI-Planet staff. And wow I didn't realize there were Nspire OSes that opened RTF-style documents.
-
What's the file size of RTF style documents as compared to XML? I'd suspect that XML styling would result in smaller tns files (eg: .rtf/.doc/.docx) so perhaps that's why they changed the styling for the release OS version.
-
from the format it looks like it could go either way, but I suspect XML would be somewhat smaller. I bet the real reason they cared enough to switch is the ability they gain to have expandable types, so they can support their fancy mathprint rendering.
-
Yes I think that reason fits quite nicely, the mathprint being better with XML. I wonder how the xml styling would work for the addition of Chinese Characters in >OS2.1...
-
Hey all :)
I need to clarify some stuff regarding the rtf and xml.
All Nspire OS's, even the new ones support the rtf based markup.
But, this markup is different than normal style rtf, and it's still embedded in an XML document (which is then in a (encrypted) zip document).
Because TI added stuff to the rtf, mathboxes and other stuff can be put in it.
You can do everything you can do with XML.
Now, I don't know when I will be able to add support to nCreator, since I got a lot on my head. (meaning I have a lot of other stuff to do :P)
-
You already did a lot, just allowing to read files created on the CAS+.
Take your time. :)
-
...so? Any news about the object of the discussion?
-
Still one exam to go, and I have a bit more time to work on stuff :)
-
Best luck for the exam, looking forward for hearing your news.
-
Well, let's give it a try again. :)
Any news?
-
Well, beside that I've got 2 CAS+'s in the meantime, and tried to hack them for various stuff, I haven't actually worked on the editor.
Sorry for that :[
