I was trying to reply to Keoni29 not to critor. Also, it has some replies on it that mention the buzzer+uart! ;)
Unfortunately, the thread has stopped a bit too short.

Nothing mentioned about that little orange pcb though. I would love to have a picture of it removed from the calc if possible.

As far as I know, this is not related to the will to develop an official SDK or not.
All development firmwares have a SDK prefix in the version string.

By the way, I was wondering if my link above was against the Omnimaga ROM images rules.

Well, Omni has tolerated unnoficial links to very rare TI-OSes no longer hosted on TI servers (such as OS 1.1), although I am unsure about the policies regarding direct links, since in the past, they were usually linked to indirectly (such as, for example, if a TI-Planet news that is cross-posted to Omni includes the TI-Planet one as source, but the link to the OS file info page is only included in the original news). If this is a ROM rather than an actual firmware installable via the connectivity software, then this might be another story, though. You might have to ask I guess.

Yes. We don't publish ROMs links. A topic has been closed a few days ago for requesting Nspire ROM for educational use...

Quick edit: but it's for hackiiiiing.... What sould E do?

So, do I remove the direct ROM link and just mention the website, for example?

Is this a full rom or just an OS that is "pubicly" available to the beta testers?

It's the OS currently available in a zip-password-protected archive file on the HP FTP.
So it was not intended to be publicly available.

Either cnCalc.org did have the pass and rebuilt a non-protected archive after extracting the files, either they've been running a brute force attack on the file since yesterday.

If the file contains a ROM or that it's unclear that it is one (or something like 68K OSes), then it might be better to remove it altogether. Besides, we don't know if HP will react worse than TI or not to any ROM/OS sharing (but again, they provide an entire emulator for free with no ROM requirement)

I'm thinking that the file was originally not password-protected (either on purpose or a mistake?) and they got it before it did.

The firmware zip file which was available at the time of the leak was not password protected, but it was a different version: SDK0.26 + Boot Code V11.

Edit: I've just removed the direct link. Tell me if you change your mind. I know it's a difficult decision, especially for this topic.

Or a higher resolution picture of the motherboard only would also help, I'd say!

Now we get a feel on how touchy this topic might become in the short term. Maybe the Omni administration could provide some help here, before it's too late and topic becomes locked? :(

I extracted the ASCII and UTF-16 strings from the files in that zip.
APPDISK.DAT could not be extracted because the text extractor program crashed every time I tried. I could look at it in a data editor though and it looks like it contains the text for the UI menu's including the characters and symbol picker menu, but I am not 100% positive.

I will try to extract the data by hand or using a different tool. I briefly looked over some text and one thing I found interesting was that it mentioned SD and MMC cards.
