So basically, whenever a program's run, the RAM is rearranged so that the program starts at $9D95, is that it? Why wouldn't changes be automatically copied back, then?

That's how shells work, and changes are automatically copied back in that case. But running a program with Asm( actually makes a copy of the program at $9D95 (this is why you need as much RAM free as the size of the program you are running). The copy is deleted after execution finishes.

Ah, I see. I was wondering why Mirage allowed me to run programs with almost no free RAM at all.

the most amazing reply of TI to this would be:

a sdk or/and asm/c support for nspire,
as this they can do simply with a software/ OS changes and wouldn't have to make a new calc...

/*

For me this would be a reason to love TI again

*/


*kyllopardiun knows it won't happens  :'(

even then, Nspire won't have 16bit depth color on it's screen, and I'm too pissed at TI for them to try just slapping together a SDK to get rid of us.  No sir, I want some real effort from them.  I'm already saving money for the prizm; I don't plan on switching the reserve sign from "Prizm fund" to "Nspire (which is really suckish) fund"

So I'll hate TI until their first color calc, which better be an improvement over even the prizm!  And they aren't going to be doing anything in that context any time soon.

Don't get me wrong -- I love their 84+'s :D
* ASHBAD_ALVIN grabs and stuffs his 84+ into his pocket, as he can't leave home without it :P

Well, if they made Nspire BASIC as good as 84 BASIC, then added ASM support, you wouldn't be saying that ;)

Well, I'd have to pick -- If Prizm has good C/ASM support AND has a good BASIc language I'll probably be sticking to my earlier point.  But I doubt what you say might happen will ever indeed happen :P  Which is really too bad

Well, I do believe if TI launch an ASM support, soon will appear the most amazing OS ever,
TI nspire CAS + 84 emulator

or maybe a TI 89 emulator, as it has been done before...

it will make it the most amazing calc for math ever...

*kyllopardiun cares about math stuff in calculators

Now, thing about an average student, if you knew you could have a powerful tool with both awesome games
and math, wouldn't you pick it instead of just a basic colored thing?

But I'm sure the "colored thing" is going to have awesome games and stuff, and the math should be simular to the normal Nspire.  Plus, we can write our own CAS :P

Most students don't really need a CAS calculator till Calculus anyways, so I'm not sure If I should spend all my money on something I won't use all the math capabilities for 2-3 years, when a CAS colored calc ill come out :P

The TI-89 and other 68k calcs have 24-bit memory addressing, so there is no need for swapping any memory cause that's 16MB of space to use. The OS is run from the Flash ROM (I think the Flash is fast enough to handle it, since the processor runs at ~15MHz or less; I don't know the exact details but different models have different processor speeds). Normal programs are loaded into RAM. I have no idea what happens with applications.
Hmm I was sure the 89T had 2.7 MB of flash or something O.o. Does it really have that much hidden memory?
I think he means that it is capable of addressing 16MB of memory. The 89T has 4MB of flash with 2.7MB for the user. There's 256K of ram with 188K for the user.
It is bad luck to be superstitious.

For some reasons, I fear if they do that they will make it a paid software. Until 2002 or so, the TI-83+ Flash Debugger was not free. We had to pay to sign apps. If you wonder why so few app games were made back in the days, that might be why.

However, if the new calc has good programming capabilities, I am sure TI might try to release a free SDK to attempt to compete.

Also the new Casio calcs (and this topic) made Slashdot front page earlier today, while I was at work: http://slashdot.org/submission/1355718/Casio-unveils-new-color-screen-graphing-calculator . That should probably explain you why there are so many guests on the forums. If TI reads that site but not TI ones, maybe they'll see what Casio is up to :P

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

The nspire looks bad, anyways a color graphic calculator loooks good, finally enough of the monocromatic 16gray tons calculators!

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.
