Now I'm glad I updated to 2.0!

I like the Idea I can reboot the calc at any time. Is it hardware based? It would be lots easier for resetting crashed ASM programs!

Yeah, it's hardware based, since it would be a bit stupid to make the button work only if your calc ran normally.

Are you sure? It has to be software-based (at least to some extent) because they changed what the button did between OS versions.

I am pretty sure it's software-based. Else, the key combination per OSes would be the same accross all calcs

I think that what it does is that it has a specially allocated place in memory where the instructions on what to do if the reset button is pressed are stored. When the user presses the button, the hardware interupts whatever the calc was doing before and executes the reset code.

Mhmm strange I swear I did try the button in 1.1 and lost nothing. I wonder if you need to hold it for a specific amount of time?
Me too.
On the OS 1.6 CAS when I tried the first 3D function viewer (not mine, the other one), it crashed and I pressed the reset button (I was a noob, don't care about it :p). When it turned ON, I lost the 3D viewer file, not all my stuff.
I think it only erase the RAM.

Wow, their very own commands crashes? x.x

That tells how crappily they test their stuff before releasing it (if they even test at all)

Wait, there's 3d available? I didn't know that! Is it a function? (Prays) I could use this in my text engine!

EDIT: Oh wait....CAS.......  :'(

Actually, the program also works on the non-CAS, but since it's written in Nspire Basic, it's awfully slow.

Wait !
They both works on the non-CAS engine !

Hmmm...now that we have C support it should be fairly easy to write a 3D grapher. Someone really needs to find/write some I/O functions, since a grapher would not be very useful without a way to enter the function.

True
But... we were 4 active forums, They are only one (omnimaga) and a half (TI-Bank) and a little piece (UTI) today I think. Nspire Yaronet section is "dead" for 3 weeks (thus, no news about Ndless2)
Either all developpers (in general) are "dead", or all that developpers are creating awesome stuff without saying it to the community. Who cares ?

There's also Cemetech, which is the second most active z80 TI forum around, but it doesn't appear to have any Nspire ASM/C users yet, nor Ndless users.

I think one major issue is the lack of OS 2.x support for Ndless and the lack of updates for Ndless 2.x. Many people don't want to keep OS 1.1. Many upgraded back because of the power management issues. There's a huge potential for developers and users, but they want to be able to do it on newer OSes.

The TI community is also not dead, altough still not as active as 3-4 years ago. The thing is that over the time, activity shifted from forums to others. Back in 2002-2004 it was all about yAronet 68K forum and the z80 one (that used to be outside yAronet). Then activity half-shifted toward TI-Gen, then later TI-BANK. Kevin Kofler kinda scared a few people away too. TI-BANK mods being very active helped a lot. MaxCoderz died because all staff are inactive, UTI is slowing down because only two are active anymore (Weregoose and Digitan) and some events last year caused some of their most active members to shift towards Omnimaga. But if we combine all of the english forums together, it looks like this year will be a 2nd activity increase in a row and TI-BANK still appears to be very strong.

Another thing is that on Omnimaga, Ndless competes daily with Axe Parser. Since most people here got either a TI-Nspire regular or both a CAS and a 8x calc, they'll choose Axe Parser over Nspire ASM/C if they're used to the easy TI-BASIC syntax.

I'm fairly certain the Nspire draws a lot of interest, still. Everytime I check the online list, many guests are viewing Ndless-related topics.

Well, I'll give it a try later. I'm kinda busy right now, so no time for calc sends.

I just got an idea. Notice that the regular nspire already has the solve command set, but when you type it in it brings up a text nox saying "you need CAS" Since the hooks are already there, is there a chance of hacking that one command to give us solve(?
