HP Calcs Live On Under PalmOS

Posted by timothy on from the symbolic-replacement dept.

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).

    The 48GX and SX roms have been freely available (courtesy HP, of course) from www.hpcalc.org, and probably other enthusiast sites. It is interesting that HP is actually backing an emulator, though. Hey, where's that RPN troll when you need him???

    I am a bit disappointed that it does not work on monochrome devices like the good old Palm Vx, which I'm happily using for a long while now. The original HP48 display was monochrome and would perfectly look on my Palm. Now only if those keys weren't color :)

    This is cool, but it's not new. There has been a HP 48/49G emulator for Windows CE for some time now. It even runs at an acceptable speed on the newer Pocket PCs. There has also been a Psion version.

    HP calculators still being sold, but nobody is sure for how long. There was thread discussed at hp.misc.calculators (that can be read at http://www.hpcalc.org). One thing is certain: the division responsible for R&D new HP calculators, the ACO has been closed during the merge with Compaq (http://www.hpcalc.org/goodbyeaco.php). In five years from now, HP will be recognized as a brand of so-so printers, shitty computers, not as an inovative and ingenious company as once has been. But that's the life... and Carly won't be near the mess... But that's my opinion...

    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.

    "dc" command on linux except that dc is only good for integers

    You probably want to check the man page on that:

    dc - an arbitrary precision calculator

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

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

  7. Observations on it.... by shlong · · Score: 5, Informative
    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.
