HP Annouces the HP Prime


Live from the Colorado Convention Center ... HP announces the HP Prime as a color graphing calculator that support touch. GT Springer made several demos and a few presentations. He did a first class job and the machine rocks!!! I can say that it is the top machine on the market. The machine will be release in the fall (?) and will be around USD145. Springer showed how this calculator can graph equalities and inequalities allow you to visualize them (which is new to most attendees, myself included).



Does it look like an RPL machine?

For ref, my NSpire can graph inequalities but its a horrid device.

It's an Algebraic/RPN combo machine.


Hi Namir,

Will G T be there for all the days? Do you have a phone with video recording capability? Can you record his presentation?




I have a camera with me. I will try to record one of GT's demos tomorrow, assuming it's OK with HP.

Well Tim posted a link to a promotional video. I don't believe I cn do better




N? Not L? Enquiring minds need to know. . . ;)

More akin to a RPL style machine. 2 SPC 3 * =>6 or 4 ENTER 5 * =>20.

No RPN programming of any kind. Programming like the 39gII.


Speaking of which, did HP ever actually release any programming documentation for the 39gII?

And there's a proper [Enter] key!

And finally in the right side of the keyboard :-)


Can it graph x^2+y^2+x*y<1? How about COS(X)=COS(Y)? SIN(Y)>X? GCD(X,Y)=1?

Didn't think so. :-)

Didn't think so. :-)

Some years back, there was talk from Hydrix about their EDGE graphing engine for graphing relations such as those above. (see http://www.hydrix.com/portfolio/index.php?id=111 and http://labs.hydrix.com/edge/graph.php) They even describe an example that was "graphed simultaneously on a handheld device with an ARM processor using EDGE."

Since the Hydrix web site shows an hp logo on their About page, I'm curious if any of their EDGE code made it into the Prime. (It's not clear if the logos represent clients or companies where employees came from.)



That's impossible -- Tim told us it was a hoax ;-)


Yes, it's one thing for an hp employee to avoid commenting on (possible) unannounced products, but to put forward disinformation is disconcerting. :-(


As I recall, he said the rumors were running out of control. He never stated that there was no such machine.

Tim, I salute you and your team for this new machine!


He said of the reports that HP was going to release a new HP Prime graphing calculator, "Looks fake to me..." and "This hoax has gotten out of hand...".

According to Merriam-Webster, the definition of hoax is "to trick into believing or accepting as genuine something false and often preposterous".

Calling it a hoax was an assertion that the reports were false (and perhaps preposterous).


Well, perhaps Tim believed that "Prime" cannot be a "product", after all...



Very Nice


Hi Namir, What about language? RAM ? screen resolution ? CAS or no CAS ? is there a keyboard or all 'support touch'? etc ...


Similar to 39gII, 32, 256, 320*240, CAS, keyboard and capacitive multi-touch. ~10mm thick.

Addition loop test - ~10000000 additions, Nqueens ~.4 (if I am remembering last time I checked)


Home run design! Nice, Nice job! Thank you for keeping the RP(L) entry - it's how my feable brain works.

Besides the obvious HP "firsts" - color, touch, Li-ion battery.. a couple other breaks from HP's of yore are the right-side ENTER key, and the non numeric-alpha name. Love the 10mm thin profile.

What is the estimated battery life? Like the 39GII, I assume it uses a standard micro-USB connector for charging, and the same port for file-transfers?

Can you please elaborate on your response to the RAM question (i.e. "32, 256")? Or is this, number and shades of color?

Thanks Tim, Cyrille, G T, et al, for ALL your hard work to design this revolutionary handheld, including your efforts to convince management to produce it. Thanks HP!

Hello Tim,

what kind of CAS is built in the new machine? Same like hp 50g or in which way whatsoever better?



Well, there's a CAS button --- unless it's for casine!



Real picture, not a joke.

I like that Jedidiah Smith recently used the same picture for the polar plot.




Is that from an emulator?


The screenshot is quite old since it isn't using the font antialiasing, and I think the physical look is just a rendered one. However, it is quite close to the actual look.

Posted the marketing vid in another thread.

This is fantastic! Top notch, and thank you ALL who had a hand in helping HP to produce such a device!


Some serious questions:

1. Looks like an evolution of a Casio FX7000. Hope the metal overlay doesn't fall off like old Casios do after a little bit of abuse. To be honest, the TI8x series get this right - they are built of the same stuff Nokia 3310's were. I saw someone using one to bash a nail in once.

2. Please don't be a resistive touch screen. They are utterly horrible [ANSWERED ABOVE: Capacitive)

3. Does it do units, rational numbers throughout (exact mode), lists, matrices?

4. Does it have any functional calls in the language such as MAP and APPLY on the 50g?

5. How long does the battery really last?

6. Does it have a constants library?

7. Are the buttons better than the HP300s?

8. Is the software more mature than the NSpire from the get go otherwise I'm worried there will be no traction.

The image that Tim posted earlier shows a units and a matrix button.

Looks good on first view :-) Some questions:

  1. Dimensions? Length and/or width?
  2. Weight with or without battery?
  3. Is the battery user-replaceable? Remember Apple :-(
  4. Any documentation accessible already? Where?
TIA for information.


P.S.: Forget question 3 - answered by the video.

By measuring the images and scaling to a 3.5 inch display, I get the same dimensions as the 39gII and the 50g. No big surprise there! Of course, the thickness is roughly half of either of those.

That would be a step in the right direction, but - alas - still another battleship :-/ Eric, there's still sufficient space for a serious (smaller) scientific instrument like a 43S.



I agree; there are still some people that want a "traditional RPN" programmable. Probably not enough people to be of any interest to HP, unfortunately.

I think there are also people that want their calculator to run for a *long* time without needing to worry about the batteries (either recharging or replacing). It will definitely be interesting to see what the battery life of the HP Prime will be, but I don't think there's any reason to expect that it will be significantly longer than that of other devices with color TFT or OLED displays, which is to say, fairly short. Certainly not on par with the 41, 12C/15C, or 42S.


To fit that large a display in, it kind of has to be a battleship.

Hopefully, it can be repurposed into a basic RPN calculator :-) The important buttons are there.

Hopefully it uses an ARM SoC for which the vendor isn't as secretive as for the Freescale STMP3770 in the 39gII.


I was thinking more along the lines of writing an application for it -- the device seems to be based that way but we'll not know for a while.

And now you get the official Youtube Video. Enjoy!
