Apparently, OS 1.7 itself just won't even work on the CAS Touchpad Nspire, while 1.1 and 1.6 do.

OSes 1.6/1.7 won't boot on a TI-Nspire CAS TouchPad with any of the 4 available keypads (84+, ClickPad, basic TouchPad, CAS TouchPad). You either get continuous reboots, either a "wrong keypad" dialog box when the progress bar reaches 100%.

Here's a photo of that dialog box:

The photo comes from that french news, which might have other usefull infrmations for you:

OSes 1.1-1.4 are booting on a TI-Nspire CAS TouchPad with the original keypad without any problem.
You can't boot with a ClickPad keypad (continuous reboots), but you can swap the keypad while the calculator is on. The calculator won't turn off or reboot as those OSes don't check for the keypad being removed.


As Ndless 1.7 will never work on a TI-Nspire CAS TouchPad with OS 1.7/1.6, it has been modded in order to be installable on OS 1.4.

According to Levak's tests, with OS 1.4, we're getting exactly the same USB- and theta-bugs as with OS 1.7.

I should still have a copy somewhere...
Too bad you can't exit the emulator without removing the batteries.

Some stuff seems to display a bit slow. I guess that might give us an idea about Casio BASIC speed on it, but hopefully some stuff will be fast enough.

And guess what... I've doubled the framerate! :p
But those captures clearly come from the Prizm "emulation" software, as a mouse pointer is sometimes visible.
Speed on true hardware can be very different: better or worse...

Me too.

I really wonder what will be their response to those new calcs... can't wait for this Winter.

If there is a response, DJ!

There may be one...
But there may not be one!


It has been clear for years that TI is not interesting into designing/building/supporting graphic calculators any more.

* TI-83+/84+ are just TI-83-like systems (1996) with a bigger Flash-ROM.

* TI-68k OSes haven't been updated since at least july 2005.

* The last TI-84+ 2.53MP OS is full of bugs and was designed too quickly just to include MathPrint (because similar features were available on the new Casio low-end graphic calculators)

* Although they have been reported online, the last TI-84+ 2.53MP OS has not been officially fixed yet.

* Most official TI z80/68k softwares (link, sdk, emulators, editors...) are difficult to run on nowadays computers. Most of them have never been updated. And the rest was only updated after years... (64bits drivers for TI-Connect for example)

* All TI-83/83+/84+ calculators are giving you a completly false answer when you type angle(-1) while being in degree mode. It just answers -Pi. A human may understand (and forget/ignore that it's supposed to be in degrees), but not a basic program.

* 2 years ago, I've informed TI of that important bug (as it is related to math). They thanked me, but never fixed it...

* The last TI-Nspire 2.1 OS has a major bug which prevents it from starting on a non-CAS Nspire with boot2 1.1 (and it cannot update the boot2 before having started fully). But TI-Nspire Computer Link still tells the users to update to 2.1. If they've just bought a new basic Nspire built in 2007/2008, the system will freeze when the progress bar reaches 100%, although the users haven't done anything unofficial.

* TI is aware of that major bug, but hasn't fixed the OS since july. TI-Cares just tell you to use the maintenance menu (welcome to TI World) to remove the OS, and to install the 1.7/2.0/2.01 OSes first, which will update boot2 1.1 to 1.4.

* the TI-Nspire screen is just crap

* the TI-Nspire is less programmable than a Casio non-Flash calculator

* TI did allmost nothing for the TI-Nspire between 2006 and 2009

* TI-Nspire are battery-eating monsters. We had to wait 4 years to get a rechargeable battery... but it's not even included in the new TI-NSpire TouchPad packs.

* TI-84+ keypad is not included any more in the new TI-Nspire TouchPad packs.

* TI may even have recently tried to discontinue the TI-84+SE


Do you need more examples?...


Let's all migrate to Casio calculators.

Don't worry, we were allready aware of his existence.

I didn't bother about 83+ OSes because the latest one is pretty fine.

I easily understand why the 2.43 OS still available on ti.com (even typing "1+1" on a 2.53MP may give you a "RAM Cleared" message...)

But why is the TI-83+ 1.16 OS still available on ti.com ? (and not 1.17 or 1.18...)
Are there some problems with OS 1.19 ?

@Qwerty not really, it's pretty much the same. There are reports that the 83+SE BASIC is slightly faster than the 84+ and 84+SE though.

I remember something about the 84+ being a couple of cycles faster for some commands than the 84+ SE.

Don't know, but the TI-Nspire in 84+ mode (it's emulating an old 84+SE) is doing something like that...
It's a little slower than a true 84+ in general, but much faster for some commands.

For example, with MathPrint, the text Disp/Output commands are faster on the Nspire emulated 84+ than on a true 84+.
They still remain slower than without MathPrint.
