TI-Nspire™ CX II-T Is Now Available!

[Namir]

Hi All,

I just purchased the "TI-Nspire™ CX II-T graphing calculator" from AMAZON. They are asking USD 157.

Is that the "TI-Nspire™ CX II-T" or the "TI-Nspire™ CX II-T CAS"?

The "-T" models have a red colour scheme, whereas the "non-T" models have a blue colour scheme. I wonder if there are other differences between "-T" and "non-T" models?

I had assumed for some time that when TI came out with their next model, it would surely have a touch screen. When I read something months ago about the name "TI-Nspire CX II-T" I jumped to the conclusion that I had been correct. Not so.

Based on https://tiplanet.org/forum/viewtopic.php...7&p=239014 (and google translate), it appears that the -T has to do with test mode. There are some other differences like having exact calculations in the non-CAS version and the removal of the wireless option.

When it arrives, please report on the keyboard. The Nspire series has had its share of keyboard quirks.

- Original Nspire Clickpad - creative arrangement of letters that didn't work out so well. Anybody with fingers wider than average couldn't use it without hitting the wrong key.
- Nspire Touchpad - better, but the removable keyboard often had problems with the contacts where the keyboard plugged into the calculator. My students often complain about keys not registering due to the plug, not the actual keys. Also, there are a half a dozen different types of keys on the keyboard and they all feel different from each other. I found it hard to get into a rhythm.
- Nspire CX - I really dislike the CX keys. They are extremely stiff with very little "travel". They remind me of my college roommate's TI-55-II. I had a TI-55 which worked okay, but the 55-II keyboards had terrible debouncing issues. The Nspire CX does not have the debouncing problem, but they have the same stiff feel.

So I'm very curious how the CX-II keys will feel.

Edit: By the way, when my TI-55 died, I bought a 41-CX (keyboard bliss).

It's the "Texas Instruments Ti Nspire CX II CAS Graphing Calculator "

Namir, can you send the actual Amazon URL. I can't find it.

[rprosperi]

Possibly this:

https://www.amazon.com/Texas-Instruments...B07RL7HM5V

...but it doesn't mention the trailing "T", so possibly not.

But, do note that for $99.99 more, you can get "Expert Wall Mounting"...

It seems to be available In Spain.

Is the PC version synchronized with the latest firmware?
I want to try the latest graphic commands.

Thanks for the info! I just ordered one. When it gets here I'll have to benchmark it against the HP Prime G2.

Yes that is the link!

Maybe the "T" letter desribes european version, similarly to TI-84 Plus CE and TI-84 Plus CE - T.
Citation from wiki:
In 2016, the TI-84 Plus CE-T was released for the European educational market. The only significant difference from the CE model is the addition of an LED that blinks while the calculator is in Press-to-Test mode.

Has anyone been able to spot any hardware differences yet?

The CX II CAS looks identical to the CX CAS, and Wikipedia lists all the same hardware spec. But they don't mention cpu, so that might be faster. Same storage, it appears.

Shame we get the garish red T version in Europe; the US blue looks nicer to me.

Oxford Educational (UK) have it listed for £144.

The new version is faster: 396 MHz instead of 132 MHz:

I wonder if the red markings are easy to read.

If it had a touch screen, I might be tempted to upgrade. I really don't like the touchpad, mainly because they combined it with the cursor keys and it is very easy for cursor key presses to get combined with unintended touchpad inputs, making menu navigation a PITA.

Given that the cursor keys stick fast, on my Nspire CX CAS at least, there's not much risk of that. No key presses, just touch pad input!

Yes. I have the PC student software 5.0.0.1701 (available from the TI education website) and it has all the new graphics commands. I'm using it to try programs on the PC while waiting for my new CX II to arrive.

[pier4r]

The ones that get it and has a bit of time can try the summation benchmark.

I wonder if the ndless team will crack it.

I'm using the PC Student version until my calculator gets here. Here's the program I use to test all new graphics calculators. If the PC version is the same speed as the actual calculator, the Prime has it beat, running this in 3-4 seconds as opposed to about 8 minutes for the CX II CAS! In any case here's a nice program to try:

Code:

Define hat()=
Prgm
:Local l170
:Define l170()=Prgm
:  x1:=xx+zz+p
:  y1:=yy-zz+q
:  SetColor 0,255,0
:  PlotXY x1,y1,7
:  If y1≠0 Then
:    SetColor 0,0,0
:    DrawLine x1,y1-1,x1,0
:  EndIf
:EndPrgm
:SetWindow 0,319,0,199
:FillRect 0,0,320,200
:p:=160: q:=100
:xp:=144: xr:=1.5*3.1415927
:yp:=56: yr:=1: zp:=64
:xf:=((xr)/(xp)): yf:=((yp)/(yr)): zf:=((xr)/(zp))
:For zi,−q,q-1
:  If zi≥−zp and zi≤zp Then
:    zt:=((zi*xp)/(zp)): zz:=zi
:    xl:=int(0.5+√(xp*xp-zt*zt))
:    For xi,−xl,xl
:      xt:=√(xi*xi+zt*zt)*xf: xx:=xi
:      yy:=(sin(xt)+0.4*sin(3*xt))*yf
:      l170()
:    EndFor
:  EndIf
:EndFor
:EndPrgm
