Yeah, i thought so too, but i am not aware of it. That's nice to hear, though! But don't you think we a need some common place to share that valuable info?

Thanks for the input. Here are some thoughts on how i think this hacking business could eventually proceed. Someone ought to write some sort of roadmap. To start with (let's take it easy  ), we need to figure out the HP Prime's system: architecture surrounding the microcontroller (S3C2416). memory map: ROM, RAM, IO, etc. During this process, some ARM disassembly will certainly be required. This step will be a bit awkward to accomplish here because we'll need to abide by the forum rules, but still feasible by other means. Please feel free to add your contributions/advice, because i'm sure i won't have enough free time to lead this process.

Guidebook, firmware and linking software did leak last week on the HP FTP server and were quickly removed:

Come on, it can only have been done on purpose, IMHO! BTW, has any of you managed to get hold of the "HP-Connectivity Kit"? That would be really interesting. And also the booter code, of course! Good news, nevertheless!

First, try to remove the battery and put it back on again. More troubleshooting details here: https://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetNumber=11900I have called TI-Cares and they have no clue what happened.
That's weird! If the above doesn't work, if i were you i would ask for a replacement unit for it can well be a hardware defect. Good luck. BTW, Welcome to Omnimaga!

I do believe that having an actual emulator would be quite (if not extremely) useful.
That would be great indeed but a lot of work too.  As HP looks more open to the community, maybe they would give the interested people some documentation so that a linking program could be coded for Linux, mainly
I think both Omnimaga and TI-Planet should be eligible as HP beta testers and be given some privileged technical info. Let's hope HP sniffers read these messages and are sensible enough to provide some more useful insight.

Actually, HP Prime is still quite a bit new for the majority of the people (me included). After some more googling we can find a lot of scattered info, though. Yesterday, i found the HP Prime Wiki which is already a good starter. What i haven't found yet is a good "HP Prime for Dummies" sort of tutorial, which would spark further interest and increase the number of potential users. For developers, perhaps some of our HP programming gurus will find some spare time to write a more entertaining/convincing demo.

Since SDL 2.0 is now out, what benefits would it offer to the Nspire once you port it?
Yeah, but beware that the porting effort of most of the current SDL apps wouldn't be that straightforward without a lot of source recoding. So, not all that glitters is always gold. I mean, SDL 2.0 is NOT backwards-compatible with SDL 1.2.

We still don't know (at least, i don't) the exact hardware architecture of the calc, except for a few details that have surfaced: a touch-screen, a 400MHz ARM cpu, 256Mb of flash and 32Mb of ram. It looks to me it shouldn't be too difficult to install on it some sort of Linux variant, namely Android. The minute this is achieved, students can install whatever cheating software they can find. So, no matter how good these 'Examination Mode's are, in the long run, they will be completely overtaken by some smart student(s). Furthermore, programming in general will be open to almost any computer language you want and there are quite a number of good open-source mathematic/scientific packages out there. Depending on the classe's size, being myself a teacher, i find it very unrealistic to implement an effective way to prevent cheating. At first, it will scare some, i concede that. Instead, you have to train yourself during some years to detect the cheater looking into his/her facial expression and gestures. So, i see it more as yet another school directed marketing feature more than anything else. As for the price, unfortunately, i find the minimum price of $150 rather expensive for such a device. Unless forced by the school/lecturer to buy such a device, students are much better off buying an Android mobile phone (maybe to "show-off in Starbucks - Keoni29" ) instead and a much cheaper calc for the examination needs. Of course, they can always lower it later if the actual selling numbers fall behind the expectations.

No such problem with my pre-release unit.
That's pretty interesting! Would you mind telling us how did you get a pre-release unit? Thanks.

Also I think the Omnimaga banner will need another update, maybe to add a second batch of calcs to the left or something, including the HP Prime. That and a front page navigation update, because it hasn't been updated since 2011 >.< (Yunhua's projects are still listed there, even though he retired a long while ago and the HP sections are still missing)
I like the banner update idea!

I guess? I've never really made video screenshots though. Also the only function that works right now is the Open one. No modifying and saving yet.
For simple clips you can try this free handy utility: Evan's AVI Screen Capture : http://www.evanolds.com/sc_main.html that works just fine. For more complicated video editing stuff you can google for 'Camtasia Studio 8' (if you use windows) and with a bit of luck find a free version as well.

Looks nice! Can you you show it in action (video clip?) using the HP Prime emulator?

Well, the thing right now is that the calc is coming out near the end of September, so with the shipping delays and stuff, it would give very little time for testing, not to mention HP might be more willing to get the calc tested in terms of school related stuff rather than programming, since school stuff is the most important part of the calc. But of course it would definitively be nice to be able to test it so we can send suggestions or bug reports.

I'm afraid i do not completely agree with your take on the 'HP Prime Gift to Omnimaga' idea. Here are some arguments that cross my mind: 1. Quite possibly the first HP Prime version to be released will include some bugs; 2. Detecting those bugs will require a lot of testing and some expertise that most of the target school students simply do not have. 3. Adding gaming features to a calc is IMO a strong selling point from HP's POV. Developping good calc games is not for noobs; 4. Publicizing HP Prime usage through free third party reviews including performance evaluation is quite a good (cheap) deal in exchange for a couple of calc samples; 5. The Omnimaga community (with due respect to other companion sites) is already worldwide known and does attract lots of both end-user students and some more seasoned calc programmers as well; 6. Last but not least, IMO you are being too modest here. Let HP read these requests and let them decide what's best for both parties. Maybe we get lucky.

That actually is more of a marketing activity and not really a testing type activity.
...
Yeah, it very much sounds like it! How about offering the Omnimaga community a couple of HP Prime samples so that experts here can test it more thoroughly and provide HP with some valuable end-user feedback. Wouldn't that be also a nice marketing gesture?
