HP Calcs Live On Under PalmOS 191

philipsblows writes "Emulators for HP Calcs have been around for a while, but HP is actually getting behind this one, allowing ROM images to be included to support emulation of 48sx, 48gx and 49g (all separately and at the same time) on your PalmOS device. Unfortunately, it has to be a color device, but this is great news anyone who would otherwise miss out on using an HP calc. Check out Power48 here." And unlike a calculator, the software is free (and Free).

      TI calculators may have had better toy value than HP's, but they were never even close to HP's as calculators.

      Sure, they were popular with highschool and college kids, but people who do real work with calculators are pretty much unanimously in favour of HP's. Of course, this is a small and shrinking group of people, which is why HP is out of the calc business.

      One of my HP's is over 15 years old, has been dropped from a third story, has been in a lake, and still works perfectly. Try that with a TI (I have, and they didn't cut it).

    • You can get HP calc emulators for PocketPC and WinCE as well. I was using one on an iPAQ over a year ago. I do not know how new this POS version is, but all the same, it isn't something you can do on WinCE/PPC and Linux PDAs already.

    As far as I know, the unique feature of HP calculators is that they use reverse polish notation by default so I expect that is what this one uses.

    RPN is similar to stacking languages where the variables are pushed onto the stack first and then the operators are applied to the appropriate stack entries. So, a + b x c should be entered as b c x a + and (a + b) x c should be entered as a b + c x

    Similar to other stacking languages like Postscript and SmallTalk.

    Note that this should be the same as the desktop "dc" command on linux except that dc is only good for integers (and you need to enter "=" to see the result). I routinely add a few extra significant digits when using dc so that I can deal with fractional values. Works nicely occasionally when doing command line scripting.
    • Wow, if it's only good for integers, I wonder why they allow you to set the precision with "k", and why I routinely use it for decimals. As for displaying, I use "p". You should really take a look at the manpage sometime, or next you're gonna be saying it's only good for base10.
      • Thanks. You learn something new every day. That is what is nice about unix style commands. And, yes p is for printing the current top of stack not =.

        You know I've read most man pages a fair number of times but there is always something to be missed. I should have known in this case since I always thought it was a glaring shortcoming but I've never seen the K used in practice.
    • Actually the 49 does not do rpn by default; algebraic is the default. I know, I have a 49G that I just checked. However, rpn can be set under the "MODE" function key.

      • is much faster to evaluate, especially on the 49g's 4mhz processor when doing symbolic shit.

      The other unique feature of many of the HP calculators was the bomb proff design. The keys are tough clicky keys designed to be used by professionals for years. HP made scientific and bussiness calculators. On the HP calcs (11B ??) has as strong a following in the account world as the HP48 in the engineering/scientific world.

      You probably want to check the man page on that:

      Look for the 'k' command. Also you should be useing p not =.

      'dc' is GNU software and should compile on anything with libc.

      • Yes sir. HP calculators are made very well. One of the things that made them special are that the faces of the keys will not have their labels rubbed off (just the main one, not the top/bottom ones) because they're not decals, but are actually plastic in another color, combined with their backgrounds.

    • Um, since other people have already corrected you on dc, I guess it's up to me to point out that you don't need to change the order of the operands with RPN. If you want to compute a+b*c, you enter "a b c * +". For different precendence, as you point out, you just change where you put the operator, but not the order of things.

    Well, it appears from most of the comments here that no one has actually test driven the program yet. Well, I just fired it up on my shiny new NX70V, and I got to say that I'm quite impressed. I already own a 48GX and 49G, so I had no moral delimmas with installing those rom images. I don't own a 48SX, so I can't comment on it. Anyways:
    • The speed is very impressive. I ran some of the TEACH examples on the 48GX mode and they fly. It's easily 2-3 times faster than the real hardware. Of course my hardware is StrongArm based, so I wonder how well the DragonBall hardware will work. Time to go dig out my wife's N760.
    • Button layout for the 48GX was nearly identical to the real hardware. Button layout for the 49G was a little strange, with the arrow keys being shoved off to the left side and the 6 function keys that used to be next to them compressed from 2 rows of three to 1 row of 6. Not a big deal, but tough to get used to.
    • As impressive as it is, I still prefer the feel of the real 48GX hardware. That machine was designed back when HP knew how engineers operated. Of course, I hate the 49G key layout and rubberized buttons, but that's a bikeshed of a different color. Anyways, even with the 320x480 screen, the buttons are a bit too small to comfortably work by finger-touch. Using the stylus is fine, but not like having the real buttons.
    • I haven't tried any 3rd-party programs. From reading the documentation I'd guess that things written in SysRPL and and UserRPL will probably work fine, but I wonder if ASM stuff will also work.

    In all, I'm highly impressed with this, though it will take a few weeks to see if I treat it like a toy or a real calc.
    • I already own a 48GX and 49G, so I had no moral delimmas with installing those rom images.

      I've had an HP-11c since about 1983 that I still dote on. And a HP-15c (the 11c's big brother, identical except with more memory) that I got at a swapmeet for ten bucks. For years I ran it on these smaller around but the same thickness hearing aid batteries I got as free samples at work.

      It unnerves me how much people are willing to pay for 11s and 15s on eBay.

      • TEN BUCKS! You dawg. Maybe I should start scrounging around swapmeets...

        I didn't know about the 15c - once I got my 11c (in 1985), I never really bothered looking at the calculator market again. :)

        re: price of 11c's on eBay

        Yeah, it's pretty frightening. Once mine gives up the ghost, I'll willingly pay those prices to get another, though. Hard to imagine HP doesn't see the market for 11c's. You'd think they could be made much cheaper with modern technology, too. I wouldn't mind a new version with a rep
      • And a HP-15c (the 11c's big brother, identical except with more memory)

        The 15C isn't just an 11C with more memory; it has a few extra functions not present in the 11C. The ones I remember off the top of my head are complex number support and matrix support.

        • Mmmmm... Complex matrices...

          Seriously, I don't know what I would have done in my circuits classes (circa 1985) without my 15C and its complex matrix support. After graduation and my entry into the fine world of firmware development, I managed to buy a used 16C for $50. What a deal! Best danged programmer's calculator ever made. Later, a co-worker gave me a brand-spankin' new 42S, free-for-nothin'. (He was the lead on my project, and I think he just wanted to keep me happy.) The 42S does everything t

    I had many HP calculators. Lved them all. Loved RPN.
    Power48 is an impressive emulator... BUT:

    1.- Start time is too long. Screen is too crowded and plain complicated for a PDA LCD.

    2.- If you need a very good calculator use EasyCalc and you'll be happier at any resolution. Fast startup and
    decent interface. Clearly not as programable nor a large library of tools, still very usable.

    Now, here is the irony: HP should have been a king of the PDA arena using their experience in

      HP's Corvalis group (the Calculator team) designed the first two HP Omnibook portable PCs (I have an Omnibook 300), which reflect the same tight design as the calculator line. Then the 'Omnibook' brand was stolen off to HP's shit-oriented PeeCee branch.

      Some of the first computers I programmed on in High School were Hewlett Packard timesharing minicomputers. Built to the same quality standards as the H-P instrument line.

    If all you want is a good scientific/graphing calculator for your Palm, get EasyCalc [].
    (It appears to be in English now, too. :) )
  • My employer back in 1993 gave me an HP19C. It's still running, has had the same batteries for, jeesh, at least 5 years now, and has a wonderful solid feel to it. Can't folks find them used? I like Palms, but an emulator just doesn't compare to a Real HP Calculator.

    • I've had my HP32S since 1988. Only one battery change. I got sick of buying a new calculator every school year, so I got the HP, and it lasted me through my entire college career. I still have it at work. If I need to quickly add numbers, I use the HP instead of my Clie or the MS calculator program because the tactile feel is just great.
  • I'm still using my HP 28S, bought in 1988 for 300$. It still kicks ass, does anything math related I oculd ask it to, and is built like a tank. Unlike current PDAs...

    • Unfortunately not quite a tank.

      I had one for the longest time (got mine around 1988 too) but had the battery door problem.

      This seems to be not too uncommon on this model - the springs inside were a bit too strong and the area around the battery door eventually broke. I used it taped up for a few years but got tired of that and eventually broke down and got a 48gx. I like the 28S better though (since I used it for so long, and to me it seems more responsive and I like the clamshell design even with the ba
  • I wrote a gtk-- based Reverse Polish Notation calculator for my Linux based computers. It only has basic and some intermediate functionality, but it does what I need.

    ghsiloP == g + reverse("Polish")
    It's not a recursive name, but I like it.
