OT: TI-Nspire 2,0 arrived



#2

Hi folks,

I received yesterday both a TI-Nspire 2.0 and TI-Nspire CAS 2.0 and played two hours or so with them.


Short answer: PERFECT CALCULATORS!!!

I found nothing to complain and look forward to spend $10 for the new Touchpad and upgrade my original TI-Nspire's. Unfortunately can the the original TI-Nspire CAS not be upgraded.

I tested all configurations with the different versions and keyboards and it look pretty impressive!

Even the new TI-Nspire with Touchpad emulates the TI-84...

Regards,

Joerg

Looks great, Joerg.

I'm not sure what you mean by this. I upgraded my original CAS unit to OS v2 and it works OK, just no touchpad, of course. I also upgraded my PC software, teacher CAS edition, to v2 and it works fine with the touchpad emulator.

One thing I noticed about the new programming commands, Text and Request, is that Text does let you split your text across several lines using char(13)&char(10), but Request does not. Perhaps TI will add that capability to Request in v2.1.

Jörg seems to be referring to the simple keypad upgrade available for the non CAS version of the Nspire only. This is the $10 option he's mentioning in his post. The v2 OS is running on my older Nspire CAS with success, just with the original clickpad.

Jörg, how's the touchpad?


#5

I don't speak for Jörg, but my personal experience with the touchpad is that it is much nicer than the clickpad, but it is still far from being as good as a touchpad found on today's laptops. When you press the MENU button, the pointer disappears. Touching the touchpad requires a few milliseconds for the pointer to reappear (i.e. moving your finger over the touchpad does not result in the immediate response of a moving cursor; there is a bit of a delay). I think I have become too used to the touchpad on my laptop, and am a bit more critical of the touchpad's sensitivity than perhaps your "normal" user.

Bottom line, however, it is worlds better than the clickpad.

See Han's comment below.

I agree 100%.

Congratulations Joerg! They look great!!!

When will the public be able to order them???? I am ordering one (or two).

They do look good. However, they still remain aimed clearly at "education", meaning schools. No differential equation graphing; still very few input and output facilities in programs (although the improvement is nice); no 3D graphing (perhaps because it isn't required in schools? I'm not sure about this). These machines are so powerful that it seems to me that they would make excellent engineering calculators or general-purpose data-collection devices. Are these latter two markets really so small that TI has chosen to ignore them?

I fear that the answer may be "yes". Will TI ever again produce a new calculator like the TI-89?

I've made the experience that functions like differential equation solver or 3D-ploting are rarely required for engineering purposes.

Personally I owned a TI Voyage 200 that I used for some time in university. When I started my first job I had it in a drawer in my office for quite a while but never used it. Everytime things like differential equations, 3D plotting or something smilar had to be tackled I used tools like Scilab ot Matlab.

Part of the reason for this is surely that these tasks were part of larger projects that needed to be documented in a traceable manner. That's something you can hardly do with a calculator unless you connect it to a printer.

So frankly, I do not see much use for such powerful calculator functions nowadays unless you need a really handy powerful unit for field use.

#11

Definitely meant for the education market, not for engineers: look at the size and position of the EE key!

#12

Nice pictures,

does anyone know if these are new improved hardware and if so what the specs are, or are the new models just variations?

thanks,


#13

Can it be re-purposed? C, C++?


#14

Egan, I did read somewhere about some hack that allows you to run C-developed apps on the NSpire, but I know TI would frown upon that since they guard their operating systems pretty closely. But it might be "possible".

#15

Difficult question!

The old SoC was labeled TI-NS2006 and the new one TI-NS2007 Magnum.

The old PCB had three memory chips, the new one misses the NOR-Flash. I suppose that it was integrated into the ASIC. Everything else looks identical.

Execution speed is identical, LC-display is identical.

I will post pictures of the PCB'son my website before the end of this week.
Stay tuned.

Regards,

Joerg
