I always love Joerg's pages, great job, keep up the great work!

Thanks for your nice words!

An ARM9, eh? Who wants to be the first to get a Linux kernel running on that? :D

There's already Nucleus RTOS inside, why would you want Linux?

To run our own programs? Duh...

I still want to know why they never released the PLT SHH1...

That's a good question. I stay in contact with some former employees of the development group but they signed a NDA (non disclosure agreement) and they have to respect this.
My guess: It was too expensive, too power hungry, difficult to operate and development costs went over the budget because of the software porting to the ARM9.

I received last week a prototype of the TI-Nspire CAS (the second production run used for the Summer 2006 evaluation) and this one is completely different from the 2007 products available in the shelves now:

- Based on a Texas Instruments OMAP instead the LSI Logic ASIC
- Very power hungry
- Display with poor contrast

It looks like a major redesign and cost optimization approach was taken the last 12 months.

I posted pictures of the new TI-Nspire CAS (which is a very different construction from the TI-Nspire) already to the Datamath.org site.
The pictures of the Prototype will show up later in August.

Stay tuned!

Will the CAS model do the same stuff the TI-89 does at the same speed?

functionality: The CAS only supports tibasic functions not programs.
performance: the inspire is 20 to 30x faster.

Can the regular nspire support ti-basic, or can only the nspire CAS?

I have a TI-Nspire and will be getting a TI-Nspire CAS soon. The TI-Nspire has programming functions and statements, but like the TI-Nspire CAS, it only execuates them in command line entries or inside defined functions. This is to be upgraded. OS upgrade is expected in September 2007.

With the potiential of this machine, an onboard 89 emulator may be possible, but it needs to be created.

I wonder what the battery life of this new calculator is like. How long will the batteries last?

Hi Everybody !

here is a review of the TI-NSpire CAS (in french) with some pictures :

have a nice day

This calculator's processor eats too much battery. I ordered rechargable ones to use because of it's power hungry circuitry.
This bulky design could've opened up more room for AA instead of AAA, just like the TI-92 series.
Why can't TI make a calc with touch screen and color??? (Of course, that would be a PDA, but with Graphing calculator functions)
