If I were to buy a new one, it would be the newest one, which would be the Voyage. But I really don't plan on buying another calc for a while.

YaHoO! TI-89's rule!

YaHoO! TI-89's rule! fits in your pocket. small lightweight. LOTS of Mem

THE 92+ FITS IN YO TOO AND ITS ALSO LIGHT WIEGHT!

what you just said is completely wrong...
the 92+ is opposite to what you just said

its plenty big
more then heavy

its like carrying 3 89s all at once or something

how many times did you have to patch and fix your pocket until it properly fit??

I have an 83+SE, and it doesn't fit in my jeans pocket (not comfortably anyway). So, I made a quick belt holster for it. I bolted a slide case to a Maglite holster, then cut the bolts short & rounded them. It works VERY well.

That's really weird... i calc holster? That ranks up there with pocket protectors...

I have an 89 and an 83+SE so i really wouldn't buy another calc, Especially not a 92/92+/Voyager... My 89 does Exactly the same stuff they do, at the same speed (12mhz, which is faster than the 10mhz 92) and it's smaller... So i really don't see any grounds for a 92x/PLTx vs. an 89... that's my 2 cents.

Belt holster? That is Awesome.

Belt holster?

How sick can you be? And I used to think I was the only person capable of inventing such sick and useless crap.

...Another dream vaporized :).

Very cool. Mine was a cell phone clip cut off and rubber cemented to a slidecase. Quite the nerd accessory :)

TI-92+ are cool but they are so big and not allowed for use on any of the AP or SAT tests. Too me I don't see why anyone would buy one.

They are much easier to use (in general) than a TI-89. You can type much faster, and the screen is bigger and easier to read.

I don't care about portability or what your allowed to use them in. the 92+ is just AWESOME! Of course, if mine helps a little in ap physics (which it DOES), all the better. My calculator is primarily an outlet of ideas for me. I didn't get it for school. I didn't even get it because I'm rich (because I'm not. I actually had to save up for it). At first, I was going to get an 89, but then I saw a picture of the 92+, and my jaw dropped.

Won’t bring a lot of attention if you are playing it when you are finished with a final.

heh heh... or using it during the final...

The next calc I buy will be the TI-86+ with Flash ROM if TI ever gets half a brain and decides to make one. Linux on the z80 calc, bay-bee!!!

I think Linix would be too large for a calculator with that size of memorey. Plus Ti calcs use thier own special kernal, which is probly not compatable with linux's kernal and file system.

ha hah
u misspelled memory as "memorey"
oh, and compatible as "compatable"
LONG LIVE 89s!

If those are the only mistakes you saw in that message you're just as bad as he is.

So let the man rest in peace.

AND THE TI-89 WINS!!!!! HA HA H A!!!! YAHOOOOOOOOOOOOO. IF SOMEONE READS THIS REPLY!

I would have to buy an HP 49G. It's CAS is superb, and I know where to get one for the same price as an 89 (it retails for ~$190 according to HP).

I agree with you, I already own a 86 and a HW2 89. The Voyage is too large and the 92 series desgin is nice buts more of a toy than anything else. The 89 and HP48G are great calcs for engineering, I am currently renting one from the school and I use it a little more than my 89, so if I go to buy a new calc it will probably be the HP48G, equivalent if not a little better than the 89, but the 89 has much better program support because of sites liek this one.

Well, I know I'll get flamed for this, so some background is in order.
Graphing calcs I have owned:
TI-82
TI-83
TI-89
Graphing calcs I currently own:
TI-81
TI-86
and of course, my trusty HP-49

After carefully comparing the TI-89, and HP-49, I decided to risk learning a new interface and ditched my '89, and used that money to buy my HP-49G for $160 (TI-89 was $150)
Additional investment:
$30 HP Connectivity Kit, I already have the TI-graphlink which would have worked with my TI-89.
Time to learn a new CAS, programming, calc interaction.

Even with my graphlink none of the programs I use to have on my old '89 would work under AMS 2.05 and HW 2. Since I don't currently have the connectivity link, the '89 and '49 are equal to me as far as programs go, so I was basing my decision mainly upon the calculator, not which has the "l33test g4mez".

I do understand that hw2patch will work with 2.05 now, but DoorsOS still wouldn't really run, neither would most any ASM program I tried to run. And I knew I was getting the HP link soon hopefully.

So there you have it. After a couple weeks of ownership, I am pleased with my purchase, but haven't found anyone in reality or online who owns one yet. I know someone's gotta be wondering this, so I'll include a list of faults for you TI guys, and a list of

That's what I get I guess for hitting send before previewing the message...

>>I know someone's gotta be wondering this, so I'll include a list of faults for you TI guys, and a list of pro's for those actually interested:

Con's:
*Calculator pauses at times, for no apparent reason ("garbage collection"?)
*Calculator CAS does a few things funny, like (5)(2) doesn't multiply them, rather it gives an error.
*It comes with very sparse documentation, I realize most people don't read the manual, but I do, and it doesn't even cover all the commands, defering to a pocket manual for that.
*A seemingly poor level of accuracy, although I may have it configured incorrectly. 449! on the HP-49 returns an erronous result, whereas my TI-86 returns a result nearer to the actual (3.8519305180280725...e997) value. The highest result the HP-49 (afaik) can return a !factor is 253. That's disappointing.
*Slow movement throughout the OS.
*Lack of a "Entry" command to recall not just an answer off the history stack, but also a past command entered into it.

The Pro's:
*-PROPER- placement of the alpha characters.
*Ability to type both numbers, letters, and space when in alpha-mode (very handy!).
*Built in clock (handy in chem classes, and to remind you when lunch is over).
*Built in sound, and extensive control over buzzer (okay, it's a bell/whistle, it comes in handy when used in conjunction with the clock).
*Better handling of Flash by OS that TI's.
*integrated RPN support.
*Ability to modify all system settings.
*3 variable fonts, ability to turn off pretty-print, ability to modify/create your own fonts.
*no need to upgrade in order to get collapsable directories.
*Support of 127 character filenames!
*innovative (and efficient) usage of "", (), [], etc.
*Integrated assembly support (Compiler & debugger), and "BASIC/Advanced BASIC" support.
*1 Mb user Flash memory, 512 KB of user RAM (afaik), each divided nicely.

And of course, more will no doubt come to mind, hope this post is helpful!

Score: +4 informative/ -1 VitrolBait

Just two things, you can turn off pretty print on the ti89 too, and what do you mean by the system settings? what system settings is it you want to change on the 89 that you can't?

And another con on the hp calcs in general, the lousy screens. really terrible contrast, and pixelsize.
Maybe it is better on the hp49g, I havn't studied it, but on all previous...

Ya, HP-49 has a bad screenthe size of TI-86 and a slower than 6 MHz processor. It has an absolutely inferior linking interface and the whole calc isn't intuitive at all. I'm not saying it's bad, it's just not user friendly as TI calcs.

I like the linking interface. It uses standard rs-232 protocol so I can send stuff to it with hyperterminal which comes with windows.

So I spliced the unit to unit link that came with it and for $5 made a link to conect to the computer.

My HP-49G (ROM 1.19-5) will preform 499! to every digit (all 1132 of them) in about 13 seconds. You are
probebly useing your 49 in approximate mode: most of the good CAS stuff happens exact mode.

see ya'

my .01 .01 + $ _ or
1 100 / 1 100 / + $ _ in exact mode

It really shouldn't matter... it should give a reasonably accurate answer in approximate mode as well. The CAS consists not only of the symbolic manipulation.

I checked out the 49G at hp.com. The screen res is pretty low - much lower than an 89.

I also have a question, are there really any good communities for hp calcs? Like TIcalc is for TI calcs? And where are there more detailed specs of the 49G? (HP.com sucked royally)

lol, check www.hpcalc.org
it has a lot of programs and info about the HP calcs

The community exists mostly on comp.sys.hp48, which
you can read by surching for it in google's groups section, but all the software is located on hpcalc.org

There are a lot of better spec. sheets on hpcalc.org under one of the documentation sections.

what the new buyers should really look for is a good CAS computer algebra system, and not new apparatuses.
Texas instruments should think first of improving the rom of the ti89 and ti92+ before taking out a new apparatus, I suggest to you that they(ti) place in its web a section of suggestions to improve the rom, as the hp in http://bugs.hpcalc.org /

that somebody communicates with Texas instruments and he/she sends him this message

Well i would get a voyage cuz seems pretty cool and i already have a TI-89 and 82 planning to get a 83+SE and a Voyage as soon as they release them...

I'm not entirely sure why that comment was there, but I think that may be the first place I saw someone saying they were going to get a Voyager (the rest are likely later in the posts, I haven't finished going through them all yet). Anyway, I would also like to get a Voyager, in order to compliment my 92+.

I believe (not sure) that the HP 49's CAS will not only do algebraic problems, but can tell you the steps it does in attaining the answer. I'm not sure on this, as I don't own one. This is why I said the CAS is superb.

The step by step feature is sort of overated, quite often the steps that the calc does are quite unintelligable.

It is still very powerful and at $106 it is quite a bargain.

Showing steps has nothing whatsoever to do with how powerful the CAS is. In fact, the more powerful the CAS, the harder it is to show the steps (for most relevant functions).

I bought my 49g for $180 and got a $75 rebate.

At office depot 49gs are now going for $106 which is comparable to an 83+ but much better.


-Samuel

wow. i oughtta check them out.

I would buy a HP-49G also, if I had another $160 to spend on a calculator. I own an 89 and none of the other calculators look like they are enough of an improvement. The Voyage 200 adds more Flash ROM, but you can only use 1MB for archive, who's idea was that?

Also, Voyage finally has a clock!

HW2 TI-89's and TI-92+'s will have new clock functionality as well.
