Color-Screen TI-84 Plus Calculator Leaked 245

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.

      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).

      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.

      • 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.

        It could be fixed with a flash upgrade, but this is New HP, not the old one where the top guys had pride in what they did and didn't look for pennies to save, so it won't happen.

    • by catchblue22 (1004569) on Sunday November 11, 2012 @03:32PM (#41951199) Homepage

      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.

        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 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.

        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.

        (Not that I'm speaking from experience here, of course.)

      • Nothing still does units quite as easily as my TI-89. I take it everywhere and anytime we're with a supplier/customer that insists on non-metric (or even worse a mix of metric/non-metric) I just let the '89 sort it out.

        I use it all the time to verify that I'm doing unit cancellation correction.

    • 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.

      Yeah but it sure us nice being able to use it for a whole semester without having to change the batteries. Not to mention that I don't ever recall having to reboot my TI-86 in the middle of an exam. People complain about some of the outdated specs, but these things were reliable and got the job done. I love my android phone but wouldn't trust it to last a 3 hour exam followed by another 3 hour exam.
    • Yeah, frankly I'm surprised people are still using these. It seems like they should be able to make an iPhone/Android app that could do much better. For $100, I'd think they could make something comparable to a cheap Android phone in terms of computing power and capabilities. If they're worried about power consumption, maybe they could switch to a high-quality e-paper display. If they're worried about security, they could make a device that lacked network connectivity.

    • Especially since TI themselves make a wide variety of advanced processor cores with built in touch screen display controllers. I'm guessing its more to do with schools requiring them and thus guaranteeing a market so why spend on R&D?

    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.

      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.

    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?

    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.
