Yes.
I'm currently working on that.

I'm just wondering if I could remove the OS, then send a more recent compatible OS (which I don't have for now) and use it to dump Boot1, Boot2 & diags.
But if this 1.1.7xxx boot2 has no USB linking support, then the calculator will be totally unusable.
You still have the option of upgrading the later developer boot2 through RS232
Did you manage to build an adapter?

Does it accept a Ti-84+ keypad ?
And if so - see if there are undocumented calls for this prototype .
It does accept a TI-84+ keypad. It's running a 2.42 TI-84+ system. I've dumped it, and it is different from the 2.42 system included in production OS 1.1. According to my hex reader, there are many differences, and many of them are in the OS area. I have an unrelated question. According to the above tests, it seems that prototype cannot exchange data through USB. Where is the USB linking code? In the OS? In the Boot2? In both of them? I'm just wondering if I could remove the OS, then send a more recent compatible OS (which I don't have for now) and use it to dump Boot1, Boot2 & diags.

Without the RSA private production keys, no.

Sorry for being late. I have no more info than you.
It's my guess, but I'm pretty sure that it will be one of those 2 things:
- either some kind of TI-84+ emulator for the iPhone or something like that
- either a special TI-84+ using a clam shell, like the Casio fx-9860G Slim

The nand reader seem to freeze randomly.
(after severall minutes with the down-arrow key stuck)
It means more work for me, but it's still possible.
(although I might lose my nerves when I'm going to film the OS... I've filmed 66% of the boot2 up to now)
But the other problem,is that it means more workk for the OCR too, as each video segment will have to be calibrated separately.

ExtendeD, I have posted severall messages about that...
What about the programs which need to use the numeric keys for menus (Norse, Nover, mViewer...) or for inputting data (Norse) ?
Such a trick should not be cared of at the Ndless level.
If I've understood well, I would need to modify all of them in order to check for arrow keys... And once the TouchPad arrows are supported, I'll need to modify them back to check for numeric keys...
Why don't you simply let the programmers the freedom to decide by themselves how they want to handle numeric key presses in their own programs?
If the "2" key is being pressed, Ndless should simply report that the "2" key has been pressed and not the "down-arrow", which is a lie.
I don't think it's hard for game developers to check for "right_arrow OR 6 OR 3 OR 9" for example...
And as programs have anyway to be recompiled in order to work with the TouchPad keypad, I can't understand at all why you've made such a strange mapping.
Thanks for reading.

Apparently, TI-83 Plus Flash Debugger/SDK no longer comes with calc ROMs. When Advent downloaded the SDK from TI website, he got told he needs the ROM of the TI calc to run it.
I remember they used to be included, as .clc files.
I just downloaded this thing no less than 3-4 months ago, so this change must be pretty recent. 
No change. The version is still 1.0 build 29, the file is still 4.15Mb large, and it still contains the ROMs. The only difference, is that depending upon your browser, TI forces you to accept a license, saying that you have to own a legal ROM copy (for example a calculator), in order to use the SDK (and the included ROMs). Anyway, the SDK uses a special CLC format for the ROMs. The ROM files available on the Internet or dumped by TiLP for example won't work with the SDK without being hex-edited.

Nice, do you think they could be used on Omni front page too?
No problem about that

I might have found a way to dump the 1.7 OS/Boot2/Diags (but not the 1.7 Boot1 yet). In that very old diags software, the "additional functions" menu has more options. It has a "NAND Flash read" option, which lets you input a nandflash address and then shows the Flash content. You can move in the flash by using arrow keys. Have a look at the start of the boot2:  Then the idea would be to stuck an arrow key and use a webcam for hours... I'll have to dump: * 00004200-0015A800 for the boot2 * 0016B000-00210000 for the diags * the OS which seems to start at 00221040 I can take the time to do it but once done, I'll probably need some help with the video files... Does anybody have an OCR software that could then generate the hex data from the videos? Or an easier idea? Thanks.

I've purchased 2 identical basic TI-Nspire prototypes. They are very rare. Have a look there: http://ti.bank.free.fr/index.php?mod=galerie&action=img&id_gal=9&id_img=129They come with the oldest 1.1 OS/boot1/boot2/diags I've ever seen: * OS 1.1.7320 * Boot1 1.1.7314 * Boot2 1.1.7314 * Diags 1.1.7387 They are detected as standard "TI-Nspire handheld" by Windows, but... - None of the TI-Nspire Computer Link versions is listing them... Not even the 1.0 version, not even by updating/downdating the driver, not even by using the Computer Link 1.0 driver... - The "Send OS" menu item is disabled. - Unlike my other prototypes, they cannot exchange data with commercial TI-Nspire BAS/CAS, prototype TI-Nspire CAS/CAS+, and not even between themselves! The "Send" menu item simply returns immediatly, doing nothing. If I'm guessing right, the USB link protocol had not been implemented yet in the 1.1.7320 OS. Seems it is going to be hard to dump anything without USB linking... Any idea?

Does this mean no more 84+ emulator anymore. Not that TI would make a good emulator for a color screen anyways.
If there are no removable keypads, then yes this would be true.
But we cannot yet completely confirm that the keypads will not be removable.
To be honest, I wouldn't be surprised if TI removed it. In fact, I wouldn't be surprised if OS 3.0 for the regular Nspires removed it too. TI stopped distributing the 84+ keypads with new Nspires and last Summer they discontinued the 84+SE in some countries. Maybe they're trying to force people to buy both calcs or want to make sure there are no games possible on the TI-Nspire. However, the design was really flawed anyway: Qazz's calc broke because of constantly swapping keypads.
But OS 3.0 is going to include the 2.56MP 84+ system. This has allready been announced on TI web site, and reported by TI-Bank.
