Color-Screen TI-84 Plus Calculator Leaked

KermMartian writes "It has been nearly two decades since Texas Instruments released the TI-82 graphing calculator, and as the TI-83, TI-83+, and TI-84+ were created in the intervening years, these 6MHz machines have only become more absurdly retro, complete with 96x64-pixel monochome LCDs and a $120 price tag. However, a student member of a popular graphing calculator hacking site has leaked pictures and details about a new color-screen TI-84+ calculator, verified to be coming soon from Texas Instruments. With the lukewarm reception to TI's Nspire line, it seems to be an attempt to compete with Casio's popular color-screen Prizm calculator. Imagine the graphs (and games!) on this new 320x240 canvas."

Indeed. I'm clinging on my HP-48s, and I dread the day they'll stop working, because absurdly old tech or not, there's just nothing better on the market right now.

If you have a Maemo device, there's a pretty good HP calculator simulator for it. Runs the same programs, behaves just the same except of course that you don't get the keypress feel from the real physics keyboard.

FTW RPN.

I think every OS and software platform in existence has a HP48 emulator. Currently I use one on my Android cellphone when I need to calculate something and I don't have the - increasingly rare - real thing with me, but as you say, without the excellent HP keyboard, it's nowhere near as fast to do anything with it.

HP still offers RPN on a few of their calculators. In the graphing-calculator department, there's the HP 50g [amazon.com] , which can switch between RPN and non-RPN modes.

They have a list of the six RPN calculators they still sell here [hp.com] (bottom of the page).

Re:And for all of us who prefer RPN? (5, Informative)

zubiaur (1207636) | about a year and a half ago | (#41951187)

Last time I checked the 50g was their top of the line calculator. Well built, powerful enough and with a good, clear, easy to read BW lcd. Software wise... it has not changed much. The 50g uses its "powerful" 200mhz processor to emulate the old 4-8mhz saturn one, the software in gneneral is just a minor evolution from the one found in an older 49g, it runs faster but thats about it. The one gripe I have with the 50g is its battery life, probably related to the fact that it its running everything emulated.

Do I hope HP will do something about its aging calculator lineup? No.
Am I happy with the current calculators? Yes.
Will I be tempted to buy a Casio or a TI? Hell no, once you go RPN you never go back.

LaughingRadish (2694765) | about a year and a half ago | (#41951421)

Really what HP needs to do is bring back the 42s and 32sii and ditch the 35s (or at least redo it from the beginning and not screw up this time, thus making the 35sii). For the successor of the 50g, I want to see the ENTER key put back where it belongs and ditch the emulation. Sheesh, there are people out there doing the engineering for this stuff for free.

If anyone can find better math software for an android device, post here?

Odd how you can get decent software on cruddy hardware, or cruddy software on decent hardware. I'd like something as powerful as a HP48 but not emulated... native. I know octave is available on android but the keyboard situation is icky.

you can find the new ones, still, on ebay (still new).

new cpu, new buttons and plastic but the same basic idea and even though it was $100, I did buy one. and one for a backup.

I hate touch screens and I loved my old style hp calc. when the 15c came back, I grabbed some to use and keep.

have not found a need for graphing. once I need more than the 15c, for example, I'll lift my lazy ass up and go find a computer to use (ob disc: I'm not in school and never asked to 'solve maths', live, on the spot, anymore, thank deity.)

Apple users have access to PCalc on both OS X and iOS, which is the best "traditional-style" calculator app I've found, and it has RPN support. It's a freemium calculator; basic functionality is there, as well as standard "scientific calculator" features (and basic RPN, but no visual stack), but you have to pay a dollar here and there to unlock everything.

Now for an aside. I first learned of RPN in an algorithms class I took a while back, and never saw the purpose for it beyond novelty use. However, a couple weeks ago, I decided to give it a fair shot. I find that I actually like it quite a bit, but the odd thing is I can't articulate why. So I ask: Why do you, Slashdot users, like RPN?

for me RPN, LISP and FORTH are the same in that regard: instead of coding, you built the parse tree explicitly the way you wanted it to be, not the way the interpreter/compiler decide to interpret your code. You do not think about operator precedence and evaluation order, you explicitly formulate it the way you want it to be evaluated and event tough it seems like that explicitation should increase the cognitive load its most good programmers that I know found that it decrease it... Now, rightfully, you could ask why... and to that question I have no answer.

I use an HP 48 emulator on my smart phone every day. Sure I miss the button feel, but with vibrate tactile feedback works okay. Maybe HP should just make an android device with nice calculator buttons. Then just make good math apps, along the lines of math cad.

If course admitting that a graphing calculator is just a general purpose computer these days would probably get them banned by schools and test proctors.

HP-15c fiasco: HP doesn't want your money (0)

Anonymous Coward | about a year and a half ago | (#41951643)

They recently released a batch of HP-15c calculators as a Limited Edition.

Sold out in a few hours, as every engineer and scientist thinks this is the absolute best calculator ever made. Everyone screaming and shouting for them to release more and make it an actual available product in the modern range.

So what does HP do? Well, nothing. They can shift millions of the things and they won't, because they just don't care. Not about their (potential) customers, not about money, not about making good products. Gold mine, these things.

I hate chinese knock-offs, but when a shady-market HP-15c clone comes out I'll order a whole shipping container of them.

Certified dumb for school use? (4, Interesting)

Re:Certified dumb for school use? (5, Insightful)

catchblue22 (1004569) | about a year and a half ago | (#41951199)

IMHO, graphing calculators are largely an artifact of the past, except in the case of school examinations. Students need a calculator that is "dumb enough" to not write the entire exam for them and not be able to wirelessly share answers between neighbouring students. When a student enters the world outside school, the graphing calculator will be largely useless. If you are an engineer and you need "smart features" when doing a particular problem, you will likely use a proper computer and a dedicated software package tailored to the task. The only reason you might need a small calculator is to do quick calculations.

Myself, I'm a fan of the old HP 15C. No menus. Excellent key layout. Reverse polish notation. Everything you need, nothing you don't. Perfectly tailored to the task of doing quick calculations.

Re:Certified dumb for school use? (2)

AmiMoJo (196126) | about a year and a half ago | (#41951529)

Excellent key layout.

A scroll wheel or maybe even a little pad would be nice, for easier editing of equations. Live update of graphs/results as you edit the equation, with a USB interface to dump results to a PC would be handy as well.

Adding a colour screen is pointless, it is the interface that needs an upgrade.

Students need teachers/profs who are "dumb enough" not to realize that graphing calculators have enough memory to store an entire crib sheet of formulas that the students were supposed to memorize.

The dumb one are quite intelligent nonetheless... For all my 1st year engineering math classes I built a software that actually did write the entire exam answer on a ti-92. It was wizard based so you only needed to select the problem type and type the equation. I had an A+ in all math classes so it worked quite well but since I was bragging about my edge, the professors there begged me not to share my software. They could not legally compel me to do so but they begged a lot since they would have to redo the entire math curriculum for that particular engineering school, I told them that I would not share my edge until I graduated and luckily for them, a virus built-into a game erased my calculator during a particularity boring chemistry class. That virus/game would format the flash memory of the calculator when you defeated the final boss. To add insult to injury, I had to train quite a bit to be able to defeat that boss (around 75Hr)....

Re:Certified dumb for school use? (3, Interesting)

JonySuede (1908576) | about a year and a half ago | (#41951969)

I am really, really, really bad at organization and business.
The entire math curriculum was design around the limitation of that calculator. Also it helped that most problems that the calculator was unable to solve by itself had a methodical solution taught in the textbook.
So for the problems where the calculator was able to compute the correct answer, I would compute and pretty print the intermediary step backward from there. For the few problems that were beyond the calculator reach I would compute a lot of discriminants, keep the one that matched a known solutions family then I would extract the meaningful coefficient and pretty print the solution with the test used.Since that software was written on the ti-92 keyboard procrastinating instead of drilling myself with math problems in the directed exercise portion of the math classes.

Re:Certified dumb for school use? (1)

TheStonepedo (885845) | about a year and a half ago | (#41951513)

Dumb enough for primary/secondary school - maybe.
Dumb enough for college (or professional certification/licensure) - no way.
In courses from calculus to physics and beyond, scientific calculators without graphical bells and whistles are adequate for use with problems designed to demonstrate understanding of a subject.
If you really need data visualization use Matlb or Excel.
If you need to test for Matlab or Excel proficiency, let the students hand-write code on the exam.
It's just too easy to cheat with technology to use much of it during testing.

Power usage.

The Nspire-CAS (shade of grey, extra longevity power) and Nspire-CAS-CX (color) are not that bad. To me, they are better than the Voyager200. The main problem is key layout (a,b,c vs. qwerty) and lack of macros / configurable keyboard shortcut.

The killer feature is lua support, so you don't have to learn or remember ti-basic anymore. Of course, they are mostly useless outside of engineering classes. MatLab and Matematica are better.

Too powerful. TI, cynically but effectively, has targeted the overwhelming majority of their calculators at the educational market, roughly in the middle school to undergrad range, depending on local and instructor policies. To this end, they gimp the devices hard enough that teachers and standardized test admins mostly don't freak out about them.

Yeah, for everything except keyfeel(which could be solved by a $20 USB or BT HID keypad with a calculator layout), the ship has sailed long ago in terms of power, performance, features, even price; but it'll be a cold day in hell before "So, I'm just going to bring this internet connected device in to the test and connect to one or more gigantic outside databases(and possibly a confederate who is helping me with the questions), that's ok by you, right?" goes over well. That is TI's target market, over which they enjoy a substantial grip.

The easy way around is to create some sort of control app for the instructor, and then require that students in a particular class/section/whatever register with the instructor's control app for the exam period.

Then I'd tell the students they can use a cell phone calculator, or tablet calculator, if they wanted.

Some of the TI graphing calculators can share answers anyway using an the built in IR port or bluetooth that some of the newer TI's have already anyway. Most teachers I have had don't care what model of calculator you use as long as it is a TI. Math classes may as well be graded by who has the most expensive TI branded calculator. For one of the standardized tests I was forced to take they only allowed TI branded calculators and would not let me use my cheap casio scientific calculator because use of all other brands of calculators were considered to be "cheating". So they supplied me with a four function TI branded calculator to do the timed test on. Meanwhile some of my classmates did have the top of the line TI graphing calculators with all of the equations preprogrammed in.
Hell several of my text books have contained TI-86 specific instructions throughout.

Yes, smartphones are capable of everything a calculator can do, and more. However, what I find perplexing is that, no matter how many calculator apps I try, I can't find one that I actually prefer over my old TI-83 Plus. Here are a few edges it has over calculator apps I've tried:

1. Battery life.
2. Physical keys.
3. Variable support. Even the best apps I've tried don't let you store many variables, or as easily.
4. Stupid easy and fast scripting abilities.

There are also some subjective intangibles, familiarity being a big one. I also like that there are no distractions with a dedicated calculator. The only thing I want that it doesn't have is RPN support, but I can always buy an HP-50g if I really need it (I don't).

I have RealCalc on my phone, but at the end of the day I still reach for my TI-86 (home) or 92 (work) on my desk. Probably because it's quicker: no need to wake it, unlock the screen, navigate to the app, launch the app, then constantly repeat the first two steps when it invariably goes to sleep before I'm really done.

TI could release the official TI-xx app for the iPhone/Android, sell different features, etc, and probably make a boat load of money.

Because an iPhone/android phone on the desk is even more of a distraction/cheat-risk than a graphing calculator that runs arkanoid. My math teacher used to make each of us wipe the memory in front of him before each test.

just emulate it (2)

kenorland (2691677) | about a year and a half ago | (#41951189)

Except for nostalgia for the hardware itself, I don't see why anybody would buy these. You can get excellent emulators for pretty much any of these calculators on both Android and iPhone. And their interfaces actually work well on phones too. Even the phone hardware is often cheaper than these calculators.

If you are graded based on your *answers*, instead of you *understanding the concept*, then your country is DOING EDUCATION WRONG!

True understanding can't be texted. It can also not be put into a multiple-choice form. EVER.

But hey, in a sane world, the kids would see understanding concepts and cheating the same way they see it in *games*. Where cheaters are laughed at and socially excluded in competitions, and cheating in single-player games is only there as a little helper to keep you motivated over frustrating parts. (Since keeping on going is key, to learn the frustrating parts later).
And where kids have fun and show pride in managing to understand and solve problems!
Imagine that!

High scores, acquired without cheating... THOSE are the real grades that matter! THAT is how education should be. Then all those artifacts of our fucked-up system... like kids hating school, it being no fun, not motivating, it feeling pointless and useless, and kids only doing it because they have to... would go away in the blink of an eye!

I suspect the only people who really use scientific calculators nowadays are students in exams. I don't know what the rules are like elsewhere, but when I did GCSEs and A-Levels, many years ago, exam boards had lists of allowed calculators and mobile phones were banned from exam rooms.

Test taking - calculators do not have WiFi or Cellular radios.

Keypad - Physical keypads are superior to touch screens.

Re:just emulate it (0)

Anonymous Coward | about a year and a half ago | (#41951441)

That's probably because you haven't tried.

First of all, touch-screens can't compete with a dedicated hardware keyboard specifically designed for punching numbers, just like no sane person would try typing a novel on a sw-keyboard, period.

Secondly, it's nice to not have to frequently have to charge your calculator like you do with your phone. Batteries last for months if not years, and it's usually not a case of "oh, shucks, battery's dead". Neither will necessary communication impair your ability to use your calculator, neither by draining the battery nor by DOSing it.

Thirdly, calculators are expensive because they have a captive market, students, who just have to buy them, usually TI ones.

Some engineers do need to pull some calculations in the field, and if you are in a construction site then consumer smartphones,tablets or laptops are not the right tool for that environment.

My Casio fx 82 still works (3, Interesting)

G3ckoG33k (647276) | about a year and a half ago | (#41951237)

after 30 years! Used, overused and abused. Thrown in the wall, broken, reassembled. Loved.

Unfortunately my even older Texas Instruments was stolen some thirty years ago.

Before those, at school we used http://en.wikipedia.org/wiki/TI-59_/_TI-58 [wikipedia.org]

And before that I got my Citizen. Don't recall what model though.

Those were the days.

BTW, is there no web page with images of all these old models? For nostalgia.

I have a Casio fx 7000 that I still use. It's almost 30 years old, and only on the third battery. In high school I used to write programs on it that turned the display into a drawing program. You could plot lines using the crosshair. I used to draw flight simulator displays on it and trick my friends into thinking I'd written a flight simulator on it.

This is 2012. Not 1982 anymore.

The only reason TI is popular is because they pay off textbook makers and contribute to elections for school board executives. $120 for something with 1/5000th of the computing power of a smart phone? A rip off.

When I moved to Canada senior year at highschool they were all dumbfounded why I had such a strange device that costed so much. In this day and age wouldn't an Android shit tablet for the same price with a crippled version of Maple be better?

Call me cynical but I did not understand why 32k of ram more is still a premium for these calculators when I went back to school in 2004. I felt like I was living in 20 years in the past. The profit margins have to be insane

Its time for TI and Casio to bite the bullet (1)

Viol8 (599362) | about a year and a half ago | (#41951279)

Either bring out a calculator that is essentially a programmable scientific computer with a PROPER programming language, (not some hobbled joke that would have embarrassed an 8 bit home computer) and a PROPER display , or just call it a day , accept smartphones can do everything a graphic calc can do except better and just stick to producing cheap school calculators that can do logs, trig and notalot else. TI sort of tried with the TI-92 about 10 years ago but the display was a joke and it was dog slow. Oh , and cost a small fortune.

Math Prof here... (5, Insightful)

Anonymous Coward | about a year and a half ago | (#41951297)

TI-fail. We've been talking, they haven't been listening. We don't want this (and I'm fairly sure I speak for Faculty and Students alike)

Don't get me wrong, color and higher resolution would be nice, but I'd much rather they sell the current device for what is more along the lines of what it costs to produce. Probably TI would still do quite well if they sold these beasts for $20....$120 is just ridiculous highway rapery prices.

Look, we (the faculty) need our students to use these. Are they outdated? Yes....but even though the students would get much more use out of tablets (which cost about the same) the TI83/84 are designed to be hard to program (and easy to reset). That coupled with the fact that they are the most sophisticated computational device that doesn't have WIFI access, we can be confident they give the students a level playing field during an exam of what is pretty much still the accepted amount of technological reliance needed to assist (but not interfere) with instruction of concepts from College Algebra/Calculus/Trig, etc. This is why we continue to use them. However, at the college I teach at, most of these are purchased by students who use them for one semester and then they become a worthless brick to the student. There isn't anything you can do with them besides try to resell them to someone else, and the cost is comparable to the textbook price, ie, significant (and don't get me started about book prices)

Its been a policy at my college that College Algebra (and above) courses require TI-83/84 calculators. However, as college continues to become more expensive many faculty are piloting alternatives. We're even getting to the point where we're considering letting the students use tablet/smartphone calculator apps (if they want) and just requiring they use a TI-83/84 at exams, which they would be able to check out or rent from the department during exams.

Why "and above"?
If the students can't hack it with pencil, paper, and the occasional scientific calculator one-liner, what business do they have taking math courses beyond algebra?

Solution: Import $20 alternative in bulk, sell them to students for $50, offer courses on how to translate from TI instructions to alternative. Students save money, your school should about break even and TI gets a well-deserved fuck you.

Those who enjoy and cherish HP calculators may be interested in the DIY4X [flickr.com] . It's a homebrewed effort to recreate the HP 41 and 42 calculators with enhancements. Is HP watching? A few individual HP employees are, but it's not clear if HP is officially aware.

MindPrison (864299) | about a year and a half ago | (#41951375)

I would like a calculator to be just a calculator and nothing else.

One of the things that I like about my TI83+ is that when I power it on, it's there, ready to use instantly.
I also have the TI-nspire with the 84+ keypad plugin, and it's a joke. If I don't use it for a few days, the system has to RE-LOAD and it's like booting windows on a calculator, very annoying. And the touch-pad is a joke too. You have to fiddle with it for minutes in order to have the arrow appear.

TI - find back to your roots, let a calculator just be a calculator. I want it to be ready when I am.

Probably still a Z80 processor. Doesn't need MAME, no need for emulation. Good thing TI finally beat CGA graphics.

Pointless self-hurting nostalgia (0)

Anonymous Coward | about a year and a half ago | (#41951443)

I can have a full mathematics suite on my laptop, Qalculate! for my quick calculation needs, and basically a full programming language with graphing (that beats the hell out of any standalone calculator) on my phone.

There is no need for standalone calculators anymore, and just like an old console that can be 100% perfectly emulated on a modern computer, the only reason it still exists, is because some ultra-conservatives (which is essentially what nostalgia is) think back to "better times" that never were better except in their soft-blur-filtered false memories.

Give me GHCi with a decent graphing library over anything else anytime! (Yes, on my phone too! It has a real keyboard and actually is a full computer, unlike your iShit.)

I mean couldnt you just get a smartphone app that does the same thing but better? Doesn't the average smartphone have a much more powerful cpu and much better graphics?
