RPN Calculators

There's an app for that. ;-)

Who else would take a job like that?

I try not to call people such names. I thought you claim to be so couth. Saying "Cretin" is uncouth :-)

Cretin is as cretin does >:-}

Not much. OTOH that sounds a lot like an HP 50; currently available for around 110 to 150 US if you shop a bit. Graphs as well and can have 6 lines of text on display.

Hmmm. Which ones? Any 48/49/50 graphing calcs?

Bah i should just search, i'll bet they are quite inexpensive (sans the graphing aspect). Then again wxMaxima and Octave are free.

Hmmm. How come for why?

These are the emulators I have installed on my Droid X: Droid48 Free42 HP-45 scientific calculator HP67 Calculator Andro12c (financial calc)

I have an HP48G and HP48GX at home, but don't use them.

I notice that nobody has written an HP35s emulator, probably because it would be difficult to emulate all the bugs.

Some have graphing. Most are free.

Yep, except they require a desktop or laptop.

Well, if the blackguard was acting like an insufferable poltroon, his cretinous behavior should be noted.

Isn't that "poultron" up there in Canada?

Get one of those PDAs, and download an RPN program. I had that on an old 3Com PDA, and it worked quite well.

Sounds like it would be a video game involving stylized chickens inside a mainframe..

It's cheap enough these days to make a custom calculator (just throw a

Could be crowdsourced if there was enough interest. I'd be game to look at parts of it, but it would have to be in the seven figures to be interesting.

PDAs have lousy keypads. ;-)

Smart phones have pretty much killed PDAs, though I guess an iPod is really a PDA under another name.

HP50g got many neat features such as USB, IrDA, graph display, and lots of memory with coin battery backup. Problem is, the software sucks. Very inconvenient to use. Features for the sake of features. I wish I could write my own firmware or at least customize user interface for this otherwise good hardware. But there is no such option.

The standard HP buttons, that later (latest?) HP calculators do not have. I was thinking more of the mechanical feel and reliability than the labeling.

yeah, to duplicate that, you'd need a 3d printer with two nozzles. although you could possibly just print the body with a void for the marking and fill the void with a thermoset resin (eg: epoxy)

I saw one calculator that used a bunch of gold-plated spring wires for the keyboard matrix, not sure what brand it was.

interface

That would constitute an unfortunate departure from the previous 41s fairly open code and to a lesser extent 48s and 49 which use a rather similar processor (i think). The switch to ARM processors was a good idea, but switching to totally closed code would constitute a huge misstep on HP's part.

There are 3D printers that can (sort-of) do this, but I think the crudeness of the result would seriously limit the market (both the demand and the perceived value).
