Btw is the calc on the photo a production model or a prototype? Will the consumer OS feature the same GUI?
Good question but I believe that if this is some "final prototype", it wil lstill look the same, and that pretty much applies to the OS look too. But of course, for the OS, that can change over time anyway.

One problem is if TI uses a much more powerful processor, will they finally drive away from their XKCD #768 mentality or will the cost of the calc be proportional to 83+ specs? :P

Also I hope that if the calc in the pic is a prototype that it will remain the same in the final release. It would suck if for example they scrapped Asm at the very end.

By the way I'm buying it the second it comes out over here. That's of course if the calc doesn't cost something like $192 or so. <_< (seeing how high TI charges for calcs in Canada)

Nintendo has confirmed that the Wii U console will have the same price in Canada and the United States.

TI... why can't you do like Nintendo? D:

I don't see why so many people think it will be z80 based. That option just seems very unlikely, considering how TI has significantly better options. Why on earth would you make a graphics chip that can interface with a 16-bit processor, but can run a true color, 320x240 display, when you can replace both with an ARM processor that you just happen to already manufacture, not to mention having the OS backend all set up.

They don't care about assembly compatibility. At all.

Well, to be honest I am not too sure if TI would be willing to recode the TI-OS entirely unless they've been doing so for a few years already. The only other way it won't be a z80 is if the 84+ C Silver Edition is actually the Nspire 84+ emulator, but modified for the higher resolution and colors.

But yeah maybe they didn't care about ASM compatibility at all and it will totally be a new emu. But then they'll lose a lot of users because one reason why the 83+/84+ are so popular is the large amount of programs already available for it.

Well, we'll see. Recoding the GUI on top of the nucleus RTOS wouldn't be that much work, though, compared to the work of recoding an OS from scratch.

They're apparently recoding the GUI either way. The question is whether they're really recreating the meat of the OS "from scratch", even if it's on top of Nucleus or whatever.

I think they are making it on top of the old stuff, i mean, why should your rewrite all the functions like sin etc.?

I hope they make it a double-buffered display for BASIC and graphing.

But if they won't it will still be possible with asm libs :P

I'm thinking of people who have to use them for math, though.

They don't need double buffering for BASIC, because it is just for math and not for games so random rendering is irrelevant.

I was referring to the problem with speed. double-buffered graphing would be significantly faster than current graphing. Keep in mind that it refreshes the screen for every pixel the screen is wide. (it might be twice, depending on if the line-drawing mode also draws the pixels) This is because of how TI's bcalls for drawing are set up:

Draw to the buffer
Render to the screen
Return from the call.

It's not an issue of random updates. It's an issue of performance.

Oh, that's right, it would speed stuff up then >.>
Maybe it is also possible to speed rendering up by just using b/w ?
I'm new to color stuff :P
