ut1238, Goplat: let's sum up things for the dumping of the TI-Nspire CAS+ OS 1.0.554.
I have done some tests for months by my side and got some similar and new results.
1) Calculator "Send OS":
The "Send OS" menu is disabled.
Even when you connect the calculator to a computer, to a TI-Nspire/Nspire CAS, or even to another TI-Nspire CAS+.
According to tests I had asked for to Datamath, the "Send OS" menu was enabled on previous CAS+ OSes (1.0.4xx, 1.0.3xx). But I've never seen those older prototypes anywhere outside the Datamath museum.
The CAS+ doesn't understand ".." folder
It has no "/phoenix" folder.
Visible folders are only:
"/"
"/phx"
"/phx/documents"
"/phx/tmp"
And nothing interesting in those folders.
So, the OS is not visible in the filesystem.
2) Maintenance menu:
Do not try menu+enter+p. It doesn't show a menu, but does remove the OS.
3) Diagnostic menu:
I haven't managed to trigger the diagnostic menu.
With Esc+Menu+G, the calculator just doesn't turn on until you remove the batteries... Strange...
4) Ndless 1.4/1.7:
Great news! Trying to install Ndless 1.4/1.7 crashes the calculator!
You can still move the pointer and turn the calculator off and on.
But that's all.
All other keys seem useless...
And except about the pointer, the screen is not updated and seems frozen: no "low battery" or "low ressources" indicator flashing, no control key flag...
Seems the main program/OS loop is crashed/stucked, but that interrupts are still working.
It would be great to try to install Ndless 1.0/1.1/1.1.1...
5) Computer "Send OS":
The TI-Nspire Computer Link 1.0 looks for ".tnc" OS update files.
If a CAS+ calculator is connected, you immediatly get a "bad file" error when trying to flash the 1.1 CAS OS, or even the 1.1 OS renamed from ".tno" to ".tnc".
I've used a Java decompiler. The sources were not 100% ok (won't compile again - syntax errors), but here is what I have understood about the "Send OS" code. Note, I might be wrong.
- I think the ".tnc" file is not sent to the calculator.
- The ".tnc" file is decompressed on the computer in a temporary folder.
- All included files are sent one by one to the CAS+ in the "/phx/tmp" folder.
- The code checks that you've sent a ".img" file, and a "manifest_img" file.
- Then, the code calls a native method installOS() with the calculator pathes of both above files.
I've made various tests by sending such files to the "/phx/tmp" folder, but the native installOS() just triggers a "Bad File" exception without telling me anything more.
That's all for today.
I've got 2 identical TI-Nspire CAS+.
If you've got any idea of other interesting tests, just tell me.
What would be interesting to do with the CAS+ is:
- installing Ndless 1.0/1.1/1.1.1
- installing Ndless 1.4/1.7
- dumping/reflashing the 1.0 OS
- dumping the 1.0 boot2
- flashing a 1.1 OS
- flashing a 1.1 boot2

Try this , its a test to see if the installer will work on the OS version you are trying.
For me it does not work on OS1.1 - the clock keeps spinning.
The test:
If you get a checkerboard across the top of the screen and the calc freezes then its possible to
port Ndless.

Thanks.
I don't get the checkerboard.
I don't get a clock keeping spinning either...
I 'm getting exactly the same symptoms I got with the Ndless 1.4/1.7 installer.

There is no specific installation procedure for the emulator. But I'm adding this section to the ReadMe file:
Code:
How do I install it on nspire_emu/Ncubate?
==========================================
Use the "connect" command of the emulator, then send 'ndless_installer.tns' and
'ndless_resources.tns' from the calcbin/ directory to any directory of the
emulated calculator.
Open 'ndless_installer' from the Documents screen of the calculator and wait a
few seconds for the installation.

Hi! I'm wondering how did you "see" the /phx and other folders? Thanks!
Do you also know what kind of "language" the calculator uses? I've came across few commands (fput, fget, scrn, mkdir, dir) and I would like to know if there is a list of this commands.

I've tried it severall times with nspire_emu 032 and OS 1.7. I'm getting the busy pointer for some seconds and a dirty screen exactly like on the real hardware. But then, instead of the "installed" dialog box, I'm getting a full reboot...

Through modified Java code which has been extracted from the TI-Nspire Computer Link 1.0 jar files. |

I've noticed that too. I believe success or failure depends on the state of the OS heap. Try doing something that will make the OS allocate some memory, like opening the examples folder or something, then run the installer. That works for me. |

Thats strange ?? 
I have been having success with the emulator with Ndless1.3/1.4/1.7 , but
I am using the older beta release[first non warmboot version - not the most recent beta release],
and modified versions of the emulator - usblink changes only. |

Just a question:
Since it was possible to emulate NES on the TI-nspire, why is so difficult to emulate the TI-89 Titanium on TI-Nspire? I believe it would be very nice to see how would the TI-89t OS perform on the nspire processor.
Maybe its difficult because nobody tried to do it yet. |

The TI-89 emulator exists. But calc84maniac hasn't distributed (any ?) sources of it due to an ethic problem. You buy a nonCAS Nspire, and you can emulate a CAS calculator ? |

I don't know, at least would be nice to test it. |

| Actually, it no longer exists because of that hard drive failure I had last year. Haven't gotten around to starting that project again. |

It existed and now disappeared. But you can watch some videos of it. xD
I am more anxious to see a good z80 calculators emulator in Nspire, though. |
