TI has finally released the v2.0 of its Nspire OS! It has many new exciting features that can be seen here:

http://education.ti.com/educationportal/sites/US/homePage/nspire-software-os.html

This new version still allows downgrading, since the boot2 code hasn't been modified. Also, the 84+ mode has been updated to v2.54MP. Also note that it doesn't yet work on Goplat's emu (something about new code concerning USB...). Naturally, Ndless doesn't work on this OS, since only v1.1 is supported.

They also have released a new version of the Nspire handheld in itself, which now uses touchpad technology, and has a completely new keyboard layout!!! The old Nsire non-CAS won't be left out as TI will also propose the touchpad on its own, thus allowing us to get the touchpad without having to buy a new calc.

Download is avaliable here.

For Ndless users with Windows 7, Texas Instruments also released a new version of the TI-Nspire Computer Link Software on their website here, which no longer freezes when exiting under Windows 7. We do not know what other improvements were made to it, though.

You can download it here.

UPDATE (March 6th 2010): It appears Ndless is not compatible with TI Computer Link Software version 1.4. You will get an error about a missing navnet.dll when attempting to install it. DO NOT upgrade to 1.4 if you are planning to continue using Ndless 1.0. ExtendeD is currently working on a fix for this.

The fact that this comes a week after the release of Ndless must be more than just coincidence. But unless Google Translator is wrong (and it very well could be), a post on yAronet says that downgrading is still possible in 2.0.
I wonder if TI intends to phase out the old Nspires and replace them with a new model incompatible with OS 1.1?

Lol epic ninja here. I posted a news about it like 5 mins later, written at the same time XD

I just added some parts of mine in yours, such as emphasis on Ndless issues, the Link software update and changing the title.

Yeah, lol, I made an epic ninja here! XD
Also note that the new version DOES have input in the form of a popup windows in Basic programs.

Sounds cool!  (If I only had a Nspire...)

With Asm, could hooks let the getKey command be possible? (Hooks like xLib)

Here's some more interesting info:
-84+ emu mode is in v2.54MP
-OS 2.0 is downgradable
-boot2 code wasn't modified
-TI will release a touchpad for the old non-CAS Nspire, making it work like the new one

Will the new keypads work on OS 1.1?

Also it sucks for BASIC gamers about OS 2.54 MP x.x

I doubt that the 1.1 OS will support these new keypads, meaning that if someone buys this new Nspire, he'll have to wait for Ndless being ported to the new OS.

You say is coincidence one week after the ndless, but I would only get sure it is a response in coding effort by TI if it disabled the downgrading and fixed the exploits.

Ninjas are getting common. :P

No it doesn't, DJ...

My speed tests are showing something very interesting...
...
..
..
.
.
.

Displaying on the text screen with MP enabled is 2.5 times faster on the 2.54MP system, than on the 2.53MP system.

For previous systems, 84+ emulation speed on the TI-Nspire was similar to a true TI-84+ speed.
So it's not the Nspire cpu that is making a difference...

Furthermore, with MP disabled there is no difference between the 2.54MP and the 2.53MP...


No, TI has done "something" special for the 2.54MP system...

The 1st question is "what?"...
The 2nd question is "can it be ported to the true TI-84+?"...

That's pretty neat critor.  I'm curious as well.  What did TI do...

Great job finding that! :)

Thanks.


So let's sum up...


Reference is OS 2.43.

With MP enabled, Disp/Output are 6 times slower on the 2.53MP...
With MP enabled Disp/Output are only 2.5 times slower on the 2.54MP!!!


DJ, can you test?
What do you think about it?

I'll be happy to read you  ;)

I might test later altough this would mean having to switch back to 1.1 later and reinstalling Ndless, right? (which takes a long while, btw x.x)

Also does Ndless works with TI-Nspire Computer Link Software 1.4?

Interesting to hear about the speed differences, though.

What I am curious about on 2.54MP is if xLIB runs fine. It would be funny if stuff that no longer worked on 2.53 worked fine on 2.54

EDIT: Ok finally installed OS 2.0. It took 10 minutes x.x Some infos so far:

1) WARNING! ONCE INSTALLING OS 2.0 FROM 1.1 (not tested on other OSes), IN 84 MODE, YOUR ENTIRE MEMORY IS CLEARED! BACKUP ANYTHING FROM ARCHIVE AND RAM BEFORE UPGRADING!!! ILLUSIAT 13 WAS ARCHIVED AND IS NOW TOTALLY GONE, AND I WAS GREETED WITH 1.3 MB OF FLASH APPS PRE-INSTALLED.

gonna reinstall Illusiat 13, some other games (such as XXR and Reuben 2) then perform other tests now

EDIT:

I haven't tried BASIC games yet, but to anyone still having an old TI-Nspire OS, was the speed difference of some ASM code THAT bad between the 84+ and the Nspire 84+ emu? Note, on the computer screen, one copy of Wabbitemu runs OS 2.41 and the other 2.53MP. They have been running for 2 minutes before starting video recording and it seems 2.53 MP runs ASM programs a tad slower, despite it barely being noticeable. Unless it's WabbitEmu?

But look at how fast my Axe Parser program (BASIC compiled into ASM) is on my Nspire compared to the 84+. NOTE: I tried my program on a real 83+ and SE calc before and got similar speed as on WabbitEmu. Also I had MathPrint ON on my Nspire. With it OFF I got same speed. I am really curious if older Nspire OSes runs ASM programs at such innacurate speed.

Btw I tried a modified version of Quigibo Space Invader clone in Axe parser too, having 6 rows of 10 ships showing up on the screen every frame, on both 2.54 and 2.53, and got pretty much similar speed results, but the 2.54 Nspire 84+ OS seemed to run it slightly faster.

The video showing Wabbitemu and my Nspire running the same program (despite using a different picture), is attached to the post.

Now gonna try Illusiat 13. I'm not gonna do a video, because I know how fast it runs on 2.53 MP with mathprint ON/OFF but I am gonna report on the overall speed.

By the way, sending TI-84 Plus files with TI Connect to a TI-Nspire in 84+ mode on Windows 7 is a MAJOR hassle x.x. You have to turn OFF/ON the calc almost every transfer else the USB transfer will constantly fail.

EDIT: ILLUSIAT 13 TEST DONE!

With MathPrint OFF, no speed difference over the 2.53 OS, altough maybe there could be minimal ones, but I haven't checked accurately. However with MathPrint ON, the speed still drops. I am unsure how slow it is, but the Illusiat menu animations appeared 2x slower than classic mode. These uses Disp command btw

EDIT 2:

Tested xLIB and Celtic III: xLIB fails like OS 2.53 MP. Celtic III works fine. Grayscale looks a bit crappy, though. This is the xLIB program I tried in the image attached below:
