I meant to say TI83+SE actually. The rest I already have more or less. And a Voyage is something for next year.

I would get an 83+ because i have a 92+ and that would make the voyage and 89 a waste of money for me

Why would you get an 83+, they can't do jack. Even the 86 can do more than the 83+. They are popular but in my opinion they are nothing compared to 89 and up!

That is kind of ... obvious. If the 83 series were more advanced than the 89 series, then there must have been something seriously mixed up over at TI's.

And I already have an 89. I just want to play with that Silver Edition calculator.

I'd get an 89. About the 83+, in my opinion, the reason they're so popular is that:
a)it's what most middle/high schools use
b)they're cheaper
c)there are more games (not exactly better, but more nevertheless)
d)now they have most of the functions 89s have
e)they have a simplistic appeal and they're good for the novice programmer

I still agree that 89s are good, if not better (I like the programming options; they have non-flickering GREYSCALE!!!)

Anyways, I'm satisfied with my 83+, but I wouldn't mind an 89...

I found a 83+ program, just the other day, that allows you to create non-flickering greyscale pics aswell, or at least, that's what the inventor claimed.

Can't tell for shure. Haven't tried yet.

Ti-85 and up have a different type of LCD driver (hardware) that allows you to make the screen flicker much faster. So fast, in fact, that you can't see it's flickering and you think it's grey. The good 'ol Ti-83 doesn't have that driver, so it is theoretically impossible to keep greyscale from flickering.

But who knows, maybe there is a brilliant programmer somewhere out there who can :-).

I can't remember, but after a lot of searching on my harddrive I found it and discovered that it was for 83+. Sorry for giving you hope :-).

Other greyscale routines for 83 can ofcourse be found in ticalc.org's archives. But they usually flicker quite a lot.

It flicker a bit on my SE, sending it to my normas 83+ right now...

Done...

It flicker almost just as much on my normal 83+

Maybe i'm gonna take up 83 asm again (that's why i bought the SE) and stun you gents with FF6 or sumthin in a year or so...

btw: Does someone know how to copy the textshadow back to the homescreen (83)? Like _grbufcpy_v for the graphscreen. I can't find it and REALLY need it.

Thanx.

The word "Link"? It means "dangerous", but also "link" as in URL-link.

And if it was my response that interested you, the correct translation is something like:

"If that's dutch; no, I don't think it is very risky. Although greyscale often crashes on the newer Ti-83 models, but you shouldn't buy that crap; the old design is much more beautiful :-)."

Yup. I would buy an 83+ just cuz there are more games. Also it is a thing of honor at my school to make billions of dollars at drug wars. Anyway,
a)I already have an 89
b)I do not have the dough
c)I do not really want one

If there's one thing you should know about math, then it's the fact that everything is possible. Even if at first sight it seems not, it still is.
Calculating the (pseudo-)inverse of a non-square matrix is done through the singular value decomposition. But there isn't any function on the 89 for that either, is there?

OK rephrase: everything is theoretically possible. Not being able to write down Pi in decimals, is because of a limitation in the way of how decimals are represented, not because math doesn't allow it. Pi is just Pi as square root 2 is just square root two and not 1,41...

At first we learned that you couldn't do things like 2-4. Then we found out you can. Then they said you couldn't do sqrt(-1). Then we found out you can. Then they say you can't do arccos(x) when abs(x)>1.... I'm sure there's more, but I haven't learned of them yet.

Also, explain how to find the "pseudo-inverse" of a 3x4 matrix, and I'll write a function to do it.

an 89 is the highest level ti calc u can take on the SAT. it has a generally better and significantly faster processor as well as several times more room for games, which are of quite high quality and refinement. an 89 may have a higher learning curve, but its functionality is immense. once you are used to navigating between applications and dropdown menus, the features will save anybody much time. there is also a bit of exclusivity which also helps to ensure that usually experienced, skilled programmers work with such a calc to create more advanced programs for it.

however, i did start with an 83+ and enjoyed it immensely--especially for its simplicity. but i have never regretted purchasing my electronically 89 (and perhaps a voyager in the future:)

I happen to own a TI-83 Plus Silver Edition and love it. I wouldn't trade it for anything short of a 92+. For those of you who have said they would like to play around with it, I would suggest that you do. I am so glad I sprung for the extra 30 bucks to get one instead of the regular 83+

89 is the boss. At first, I was worried that I may have wasted money for a complicated "toy," but Its bailed me out of so many Algebra II quizes, tests, and exams its not even funny... The link cable is worth it also, 'cause I put VTP89 (Visual Pereodic Table), and that things chem. equation solver bailed me out of lots of chem quizes and tests.

I have a ti-92+ and an 83+ and 2 86s. I may only be a freshmman(in my defense I'm taking precal(maybe calculus) and trig next year), but I will be buying a voyage 200(minix anyone?) and an 89(I'm gonna slip it into an 83+ come acts.)

The 83+ does suck, the only thing that it can do better than the 86 is averaging.
