So I just got a shiny new Nspire with Touchpad! I don't exactly know where to start with setting it up, though.
Questions:
1. How do I switch the OS to the CAS version?
2. How then do I get the OS to 3.6?
3. Will any of this affect 84+ keypad compatibility?
-
I'll answer the last question first, because my answer is easy: I don't know :P
Now, the first question is kind of easy to answer now that KhiCas (http://tiplanet.org/forum/viewtopic.php?p=166225&sid=6f5ce6a425272cdd6cea6d1744e301f8#p166225) is out. You just need to Ndless your OS and you have a CAS, no matter what your hardware revision is and no matter what your OS is (as long as it runs Ndless so 3.6 or 3.1).
Otherwise, if you want a real CAS OS on your calc, then you'll have to use nlaunch. The problem is that you can't have a CAS OS 3.6 with nlaunch. You can have a non CAS 3.6 OS, and every 3.1 and 3.2 OSes (CAS or not). You can even have two OSes on your calc if you want so you can have 3.6 non CAS and 3.1 CAS.
So what do you want ? :P
-
Well Nspire non-CX doesn't exactly have the most data storage space...
So you're saying that the when I use ndless I gain access to the CAS? If so that's good enough for me. I just want to be able to run my CAS programs from my CX CAS.
And just to be sure, none of this affects the 84+ touchpad, right?
-
You can't run TI's CAS with 3.6 on a non CAS calc.
If you do it for 3.1 you lose the 84+ keypad compatibility.

The 84+ touchpad is in its own happy little world. ChiCAS (ha! English) is NOT normal OS-based CAS. It's a bridge between the Nspire documents, Lua, and the Ndless Giac/Xcas backend. You can only use it in the KhiCAS document. It's better than nothing, but not everywhere.

Um... which of these is right?
Also, about the whole CAS thing. Can I run the 3.2 CAS, and if so, can I use ndless with it?
-
The CAS os does not include the 84+ ROM and probably emu so you can't use it.
To your questions : yes and no.

The keypad was made for only the non-CAS models, so the CAS OSs won't have the 84 part. The 84 emulation just sits in it's own corner of the OS isolated.
-
So basically, I can either have a CAS OS or I can have 84+ keypad work, but not at the same time.
-
That pretty much sums it up, yeah.
-
Thanks everyone. I guess I'll upgrade to 3.1 for now, and nlaunch 3.1 CAS, at least until my keypad comes in the mail.
Oh and also can I run ndless in nlaunched 3.1 CAS?
-
You can. In fact, I do.
-
So I've been trying to install nlaunchy for the 3.1 CAS OS. However, whenever I go to the maitence menu, I can't delete the current OS. How do I install this?
EDIT: And here's the readme http://www.ticalc.org/cgi-bin/zipview?nspire/asm/programs/nlaunchy.zip;readme.txt (http://www.ticalc.org/cgi-bin/zipview?nspire/asm/programs/nlaunchy.zip;readme.txt)
EDIT2: So I did some testing, and I noticed that when I had the 1.4 Boot2 installed, the OS could not be deleted from the maintenance menu. When I pressed 2 on the menu nothing happened. This is a problem, as you have to delete the OS to install the other one. Anyone know how to fix this?
-
I have a question about this. I have the Nspire touchpad, non cas. You guys are saying that it's not possible to have the CAS OS installed without losing the TI-84 functionality. Why couldn't I install 2 OS's? 3.6.XXX and 3.2.XXX. Then boot into 3.6 for the use of the 84's keypad and reboot into 3.2 to use CAS?
Would that work?

It would work but you have a very limited amount of memory available on the Nspire Touchpad so you can store much stuff besides the two OS's.
-
I'd like to try doing that. Could you please point me in the right direction? I can't seem to find a write up that works. I've managed to install 2 OS's, but either they're both CAS or their not. I used this guide.
http://tiplanet.org/forum/viewtopic.php?f=57&t=13213
I installed 3.1/3.2, but can't seem to figure out how to install one CAS and one non CAS.
Thanks!
-
You can mix and match OS's. I myself dual boot 3.1 CAS and 3.6 non CAS on my CX.
-
Thats awesome, and what I'm trying to figure out how to do. I have the CXCAS version of the calculator and I also have the old touchpad Nspire as well. I use them both, but if I could figure out how to install a version of CAS on the touchpad calc, I could use it and switch out the keypads for class. Then I wouldn't have to carry around both calculators.
Is this impossible on the non CX version of the calculators?
-
It is very possible. Just take the 3.6 non CAS and 3.1/3.2 CAS from the switching packs.
-
Alrighty.. Thanks! I'm working on trying to make it go. I've installed the non CAS 3.6 os. Then downloaded the 3.1/3.2 switching pack. I installed ndless and all its files. Disconnect usb from the computer, or it hangs. Then it reboots and and launches nandmngr I think? Anyway, I follow the instructions and press 2 for boot 2 area, then boot 2 again to flash.
If I press 1 and select CAS, it comes up with a warning that the image is rejected as determined usage if flashed on this model.
So, I make sure that the boot order is Boot2, Diags. Then press 0 to exit.
Now, it's time for Nlaunch. I think this is the step that I'm screwing up. Do I choose to install the CAS version from the get go? Do I choose the non CAS version that matches my calculator and then when it asks for an OS install the CAS version there?
-
If I try to send the nlaunch.tnc to the calc when its at the "operating system not found" stage, I get the "wrong handheld type for OS being sent" message. If I rename it to nlaunch.tno, it goes and installs the CAS OS, but it installs the CAS OS on both OS's. I can't figure out how to install one of each. :banghead:
-
Send the nlaunch.tno. Your calc is not a CAS model.
-
Alright, thanks! I'll try it again. :)
-
The only way I can get the CAS OS installed is if I rename the nlauch.tnc to nlaunch.tno. Otherwise I get the OS mismatch warning. It installs the renamed CAS version thinking its the non CAS. The only issue is both OS's are CAS then. Ugh..
-
What you need to do is mix some files. Take nlaunch.tno and OS 3.6 from the non CAS pack, and replace OS 3.1 or 3.2 in it with the one from the CAS pack.
-
Okie Dokie. I'll give it a try. Thanks!
-

Man, I really appreciate all your help. but I can't seem to figure this out! I downloaded and installed the 3.6 OS and then followed the instructions.
In the switching pac, I can't find any OS's. There are directories for the CAS and the non CAS versions, then nlaunch has 2 different versions but they aren't part of the CAS/nonCAS directories. Is it the phenix files? Is the the operating systems?
-
Actually I have no idea how the packs are structured because I did all that manually. :P I'll look into it tomorrow and make you a custom pack.
-
Iirc, this will not work on any hardware revision >J or else you will screw your NAND chip to all hell and back?
-
Yup, all the guides warn not to do anything with revision J or above. Mine is super old though. The touchpad that I'm using is revision C.
-

Dude, seriously, that would be awesome. I genuinely appreciate that!
-
The revision J thing is only for CX calculators. You can safely disregard it on grayscale models.
-
Yup, my CX CAS is revision J. That's okay though, I have my old greyscale one. :)
I wish they would have done more with the changeable keyboards. Seems like a cool idea.
-
Did you ever get a chance to take a look at the 2 OS's for me?
-

Woops sorry I forgot. :P I'll look into that asap.
I suppose you want 3.2 and 3.6 right ?
Edit : There is no need to make a custom pack. Simply follow the non-CAS instructions but use the phoenix.old.tns from the CAS folder instead of the non CAS one. Then you'll have 3.2 CAS and 3.6 non-CAS with Ndless.
-
Thanks so much! I'll give it a try this evening when I get off of work! I truly appreciate it!
-
I did what you said and it worked awesome! Now I don't have to carry around 2 calculators! I wish I was smart enough to know how to edit the CAS OS to include the TI-84 files, but rebooting into one or the other works great!
Thank again!

I agree, but the issue with the changeable keyboards was that the contacts eventually became worn out after constantly swapping the keypads back and forth (especially with gbc4nspire). If they ever revive those keypads, they need to redesign them. I wonder if doing them like Super Nintendo cartridges would be better? The only issue would be dirty connectors and having to blow into your keypads, but SNES cartridges took about 10 years before finally becoming dirty and not playing every time from first try.
-
Hey, it's been about year since I made a post here. I heard that now a days you can run nlaunchy on a 3.6 calculator? That is, would I be able to swap between 3.6 CAS and 3.6 non-CAS on my touchpad nspire?
If so, do I still need flash the boot2 to 1.4 using nsNandManager? Or is the method of doing this different now?
