New High-End HP Calculator? 345

Posted by Hemos from the graph-the-heck-out-of-it dept.
mschaef writes "There's a pretty convincing looking story over on hpcalc.org describing a new high-end HP calculator. The bottom line: 75MHz ARM9, USB Port, IrDA compatibility, 128x80 display, and a slot for SD cards. It also looks like the same basic software is running, either ported or via emulation of the venerable Saturn (HP-propriatary) CPU. The full story is over at HPcalc.org. It's good to see HP back in the game (hopefully) like this."

      I got rid of my HP48G+ two years ago mainly for the reason that it was just too damn slow. I loved the RPN-by-default entry, though, and I seriously loved the clackety keys and the big fat ENTER button on the middle-left-hand side of the keyboard. It was really the lack of the latter that led me to buy my Texas Instruments TI-89 instead of the HP49, since the TI can be made to accept RPN.

      If only HP had kept the HP48 keyboard layout on the HP49 I wouldn't have deserted. Seems the new model seems to be following the same pattern.

        Yup. My HP48SX still works great and I use it frequently. I got it within a month of its being for sale in our student union (upgraded from a 28S) and think it's quite possibly the best calculator ever made. I can't tell you how many times it's been dropped from desks and has only lost a vertical row of pixels (the 4th from the left). Definitely one of the best, if not *the* best, that HP ever made, IMO.

      I've had my 48GX for almost 10 years. It has fallen off desks and out of trees,
      been crushed at the bottom of a backpack countless times as the backpack was
      tossed into a corner (pretty close to your hammer behavior), been rained on, and
      still shows no sign of wear except for the rubber feet which are somewhat worn
      from use on concrete.

      The 48GX meets my needs and until it stops working, I'm not going to replace
      it with anything. However, if this new calculator is built with the same solid
      construction and has the same wonderful user experience, then I would have no
      any problem recommending it to people.

            At Boise State University, there were no algebraic calculators allowed in most Calc and DiffEQ classes. They were allowed in engineering classes, however. The assumption was that, post Calculus, we were learning about engineering, not math. The problems were not designed to trip us up on the math, but, rather, on the engineering!


            That being said, I have to say that I think that my 48GX is one of the best calculators ever made in terms of speed, size and ease of use. However, indefinite integrals are the devil on it! A TI92 makes them a piece of cake. Tests involving fields just couldn't be done with the 48GX because there wasn't enough time. I was lucky enough to be able to afford both the HP and the TI, so I could use whichever tool worked best.


            As a practicing engineer, though, I only use the 48GX. I think I've used the TI92 to balance my checkbook when the HP was at work, but that's about it...and I only really do arithmetic on the HP anyway...computerized field solvers do all of the differential equations for me. Welcome to the real world!

      That's likely a non-issue. The HP 48 series had IR capability, but the receiver's effective range was about 4 inches when taking signals from another HP 48. Definately not easy to cheat with.

      HP calculators have had infrared beaming for at least twelve years; my 48SX was top-of-the-line when I was a sophomore in high school, and supported the beaming of programs, equations (I guess, we never used it that way) and other goodies. Like the Palm handhelds, though, the range is too limited to be used for cheating. You have to have both units a few inches away from each other, too far unless you're communicating with someone on the same table as you--in which case you're better off just writing it down on paper.

      I miss my HP, I really do. RPN took some getting used to, but I put that thing through its paces for almost four years--trigonometry, calculus and pre-calc, four years of Math Team (don't laugh, it's no geekier than Slashdot) and an AP exam. Once I got to college, though, the math classes got more proof-oriented and less numbers-oriented. If I'd been an engineering student, I'm sure it would have been invaluable, but as a mathematics major it got relegated further and further back in my desk drawer. Nowadays I can't even remember how to use most of the power functions, let alone graph a polar parametric equation or plot a vector field.

      To be fair, TI calculators can do almost everything those HPs could, and for a lower price. If HP can still make a top-of-the-line today, though, I say more power to them.

    • I'm sure some people still prefer to work with real, physical buttons rather than a touch screen. Also, you can get more detail on buttons when you don't have to rely on a 320x480 (or smaller) screen.

      If you're using a calculator enough, it will be better to have one of these rather than a PDA masquerading as a calculator. Also, if all you need is a calculator, you might as well get one of these which will probably end up cheaper than a PDA.

      • I think that by changing your idea of the interface a PDA can become a very useful calculator. Handwriting recognition is very good these days. Imagine writing:

      lack of numberic keypad makes it WAY too slow for real heavy duty use, add in the fact that there is no symbolic logic package for a PDA that I am aware of and you can't compete with calculators like this. (btw the Ti-89 is basically Maple in firmware, Ti hired the guys behind Maple to write all the software for it). IF there were a symbolic logic app for Palm or another PDA then it might compete, but you would still have to deal with the slow input, and I can guarentee the app would not be free.

      It's really a matter of perspective.

      We have PDA:s that can also make cellular phone calls. We have phones that can double up as PDA:s. They seem to aim for exactly the same market, but, of course, they don't, since they're best features are aimed at different uses.

      Same thing with calculators. I'd love to have a HP calculator that will also function reasonably as a PDA. I'm a lot less interested in a PDA that can also do some calculator functions.

      It's all about where the focus is. Take the keyboard as an example: a dinky on-screen keyboard, or aphanumeric keyboard just isn't nearly as functional and convenient as a 'real' calculator keyboard a'la my deeply missed HP15, where all the functionality is right there, at your fingertips. Likewise, a phonepad isn't really that good for PDA functionality, and a touch screen isn't really that good for a phone.

      Also, the software for PDA:s are of varying, and unknown, quality. One thing that really made the HP line of calculators stand out was their attention to various corner cases. When you got a result, you knew that was the correct one, to the practical limit of the hardware and encoding used. The Palm calculators I've tried have inevitably had various bugs and have missed special cases that made you get the wrong result from time to time - they would not handle over/underflow correctly in all cases, or use algorithms that would not give the stated precision over all of it's range, and so on.

      My dream would be a new HP calculator with the format and design of the HP15c, but modernized (faster CPU with more memory; pisel screen, rather than segment, and so on). That one was a nearly perfect unit for me. After fifteen years, I had unfortunately dropped it, spilled coffee and soda in it, buried it under piles of books, stuffed it in dirty, dusty bags and submerged it too many times and it gave up :(

      • The real issue is that SD seems to be the favoured choice of memory storage/extension in new hardware, despite higher costs to both producers and end users.

        Consider that the CF spec is an open one and involves paying no encryption license fees to an organisation like SDMI: it makes me wonder whether the execs are casually treated by SDMI reps to lavish holidays at exotic destinations in exchange for securing the slot for SD.

    Another thing is QA. How are we to be sure that some program we downloaded to our PDA does the calculations correctly. When you buy an advanced calculator you can be pretty confident that the different mathematical functions has been thoroughly tested. Since the key sellingpoint of a calculator is the ability to, well, calculate, the vendor has probably gone to some effort to ensure that it is infact capable of doing that correctly.

    The calculator looks nice, but I think HP may have a hard time finding a market for it. In fact I wonder if any effective market niche still exists for non-Texas Instruments high-end calculators. The education market -- high school and college math/science students -- is pretty well ruled by TI and has been for years since TI came out with the TI-92. Nearly all of the calculator-oriented curricula out there is designed specifically for TI calculators. And part of this is HP's fault -- when the TI-92 came out, a colleague of mine was at a math teachers' conference and asked HP if they had anything coming out that could compare with it, and their answer was a resigned "Nope". And for years, the textbooks and lab supplements went specifically toward TI machines because nobody else bothered to keep up with them. Although this machine does compete with TI's, it seems, I think there is just too much brand loyalty and curricular momentum in the education market towards TI for HP to make a dent.

    The only thing that's successfully competed with TI calculators has been computer algebra systems (you can get a good, cheap CAS program like Derive -- another TI product, by the way -- for $99 for the student version and $199 for the professional version) and PDA scientific calculator programs. Existing hardware and software is more flexible and less expensive than this new HP. So if this isn't intended for the student market, I wonder who it is intended for, and if it'll actually sell once it's out.

      TI calculators are dominant in schools.

      And that's all they're good for. They are piddly toys for students.

      The HP 48GX, despite being far older and slower than the TI-92, is dominant in engineering. At my company, there are two types of calculators people use: HP 48s and PCs running Matlab. I have NEVER seen an engineer here using a TI.

      Even in my high school, almost everyone who was planning on going into engineering disciplines bought an HP48. As to your comment, "And part of this is HP's fault -- when the TI-92 came out, a colleague of mine was at a math teachers' conference and asked HP if they had anything coming out that could compare with it, and their answer was a resigned "Nope"."

      Then why did at least two people I know in high school buy TI-92s, only to replace them one year later with the *significantly older* HP-48? The TI-92 sucked. It was a monstrosity that was DOA in the education market because it had a QWERTY keyboard and hence was not legal on any standardized tests. The HP48 was legal on most tests if you blocked its IR port, and most proctors didn't even bother checking that. (It was widely known that the 48's IR receiver was very weak and only good for calc-to-calc communications of 6" or so. There's an ongoing debate as to whether this was done for power savings or to keep the calc test legal.)
      • Granted, the 48-series are dominant in engineering. But why whould engineers replace the 48G with one of these 49s? The 48G does the job, and for heavy work, as you correctly point out, you use a computer anyway. So the speed of the calc is not that relevant. And the battery life on the 48 is absurd (measured in years, in some cases).

      In education, TI rules. People can't stand HP calculators. But it's kind of nice to have one while in school, that way no one wants to borrow your calculator. Or if someone does ask to borrow it, and doesn't know how to use it, it's always a good laugh trying to explain how post-fix (or reverse polish, if you prefer) notation works...

    I've used an HP 49G ever since it came out. It's impressive in it's strengths, and nearly as impressive in it's weaknesses.

    I have found in several situations that the CAS, while a bit slower, can come up with a correct answer to a complicated transform that causes a TI89 to barf and quit. It can effectively calculate factorials up to about 250!, which I think is very neat (if not all that useful). The equation writer is incredible - it's like entering equations in Mathcad, easy to see what they ~really~ look like, and quick too. Clock, calendar and on-board help menus are very useful as well. RPN always adds mucho score points. Too bad it defaults to algebraic out of the box...

    My biggest complaint is in the ROM - only the latest (non-HP approved) ROM revision fixes the more serious bugs, like random garbage collection delays, in the calc's OS. There's also the standard complaint about the sucky rubber keys, and the annoying screen design & resolution. Speed isn't too bad - the general code is optimised well (much of it was taken from the 48 series).

    This new addition appears to fix all, or nearly all of the mistakes that were made with the 49G. I look forward to reading reviews of use.

    Maybe I'm jumping the gun a bit, but it looks as though I may add a new RPN machine to my collection soon.

The keypad is nowhere near as good as the 48GX. The screen on the 49G scratches easily, and the slip-over hard case sucks compared to the nice zippered pouch of the 48 series.

This blows my mind why does a calculator need a 75MHz processor. ARM9 is way overkill they should have, assuming that they really wanted to use an ARM stick with the ARM7 which is fine for basic computation it just misses the support for caches and longer pipelines. The ARM7 is smaller (smaller die lower cost), and lower power (longer battery life). Hardware design seems to be more about bragging rights that producing a good product. The SW guys all want to use C++ so they don't have to understand the processor, C++ is ussually 20-30% slower than C and 100-400% slower than assembly and assembly is what a calculator's code should be written in.
