News / New HP Prime OS Version: 2014.0331
« on: May 27, 2014, 12:44:47 pm »
For your emulator, calculator and connkit. Easiest way to get them is to use the check for update mechanism in the emulator or connkit.

The primary focus of this release in terms of new features was improvement of geometry and statistics. The primary focus of the connkit was around the main UI (not the editors for specific object types which were essentially untouched).

Four chapters in the user guide were changed, however they could not be rolled directly into the original document and are instead a "supplement" for now. The emulator has them, but they are attached to the end of the existing manual brought up by selecting Help->User Guide in the emulator windows menu. If you'd like the separate "supplement" file, it should be up on the HP support page shortly.

HP Prime – Release Notes

Date Released: 2014/03/31

Internal Versions
          Firmware Version:     2014 03 31 (6030)
Virtual Calculator Version:     2014 03 31 (6031)
          Connectivity Kit:     2014 03 31 (6026)

This release of the Prime Calculator firmware and associated PC software delivers significant new features and fixes outstanding issues. This document is not a complete list of all changes, but highlights specific items. All users of the HP Prime calculator are encouraged to upgrade for the best possible experience.

Backward Compatibility
There is limited backward compatibility between this and earlier releases.

Older Prime hardware (Revision A) does support this release, however the wireless, unit-to-unit, and data streamer functionality is not supported on earlier models. In the Help->About HP Prime screen the hardware revision will be displayed along with software version information. Mixing and matching software revisions is not encouraged and may cause unexpected results. Users are strongly encouraged to first backup their calculators with the older firmware and Connectivity Kit - then upgrade all their calculator software (firmware, Connectivity Kit, and Virtual Calculator).  Upgrade the Connectivity kit first, before upgrading your calculator firmware. This order will produce the best experience.

The geometry application and inference have received significant updates and earlier data files will not be compatible. Old data files from earlier revisions will not load and and a new empty data file will overwrite the old one.

Due to some specific issues resolved, certain user programs may not run on the new system without changes first. Specifically, any commands with the Σ character in the name may need to be corrected to use the correct sigma character. Function variables will now also error if the function parameter is using a reserved system function name (example: SIN or COLOR). Additionally, the TRIANGLE commands were modified to allow TRIANGLE, LINE and FILLPOLY to share similar data and syntax to enable easier creation of complex 3D drawings

New Functionality (Connectivity Kit)

HP Calculators / Call for Beta Testing Applications
« on: April 07, 2014, 01:10:27 pm »
Periodically, the HP calculator group will ask for applications from individuals interested in beta testing projects. We ask for some information in order to generate the best cross section of users to hopefully catch as many issues as possible before a release. I can't select everyone, and not everyone is interested in each type of product.

Even though this is posted in the HP Prime forum, that does not mean there will not be other types of products (basic scientific, financial, mobile apps, etc) that need testing. This is just an application for general interest and you can indicate which types of products you might be interested in testing.

If you are interested in any however, please download a form and send it to me. Email is probably best. timwessman is my name, and I am at  (this is your entrance exam - you must figure out the correct email address... :) )

While we don’t expect anyone to devote an unreasonable amount of your time, those that consistently find issues, perform tasks and generally contribute quite a bit are usually asked to continue as beta testers long term.
Sometimes, there are things you may not find extremely enjoyable to work on (for example, a non RPN machine or similar), but we may ask you to assist. Again, those that are willing to focus on specific areas or tasks are usually asked to continue testing in the future when the more exciting projects are around.
You are allowed to focus on specific areas of interest, but we ask that you don’t exclusively focus on areas of interest. There are always “boring” areas of products that need thorough testing as well.

In short, those that have positive attitudes and contribute get to continue for as long as you are willing to share some of your time. If you are fun to work with, we want to continue working with you!

As a beta tester, you will be required to sign a confidentiality agreement/non-disclosure agreement before any paticipation.  We ask that you do not discuss in outside locations, post images or hints anywhere or discuss with people not involved in the testing. As far as I can tell, there has never been unauthorized leaks which means we can continue to trust the community as a whole.
If you are sent materials/units, we are also required to have you sign a form that basically states “HP is not responsible if this device destroys the universe and HP may request the units back at any time.”

Beta testing is a lot of fun! It is always exciting to have behind-the-scenes knowledge about what is ongoing, and to have a part in shaping the way products are formed, and to be involved in something for which we all feel passion. Often those involved in beta testing come up with new ideas that later appear in products, have keyboard layouts or product ideas discussed for feedback, and generally get to be involved with the calculators we love.

The download at the top of the list is a PDF form allowing you to type directly and is the easiest format. If you'd prefer the odt or docx version however, they can be downloaded as well.

Other Calculators / TI CAS question: System of linear ODE solving?
« on: December 31, 2013, 11:37:42 am »
Not sure if this is the correct place to post this question. I am trying to figure out if any of the TI CAS calcs (nspire, 89 etc) have the ability to solve *system* of 1st order linear ODEs natively.

Here's a link ( of an example. Thanks.

News / First PRIME Update
« on: December 03, 2013, 08:35:19 am »
First updates are live. The check for update in the emulator/connkit should find them. If not for some reason (usually due to proxy or other funky network things on your end, use Many thanks to people who've reported issues here in this forum or in other spots. You may notice some direct called out items that go back to a specific post. Even though we consider this a "bugfix" release with no empasis on new features, there are still about 2-3 times or more new capabilities compared with the recent "2.0" casio update I saw...  O.O

Items of interest for many here might be the new TRIANGLE and FILLPOLY commands. The TRIANGLE command allows you to pass a large matrix of vertices, colors, rotation data, and z-clipping info (solid colors only at the moment). This means you can draw complicated 3D shapes in basically a single user function call! Here's an image of a 3D graph drawn with one single draw command. Oh, and did I mention I could rotate it at about 20-25 FPS with no optimizations yet? :-D

Who's going to get on that X-Wing game.... ?  ;)
