Title: Even more early TI-Nspire prototype discovery
Post by: critor on January 02, 2012, 01:39:58 pm: In a previous news (http://ourl.ca/11758/222008), DJ_O was revealing you some of my discoveries on the oldest Nspire prototype which was known to the Internet at that time, the P1-EVT2 which was running on Boot1 and Boot2 from february 2006.

As you can guess, a P1-EVT1 should have existed before that... And yes, it does exist!

Thanks to the DataMath museum (http://datamath.org), TI-Planet is revealing today the 1st photo of the P1-EVT1!

It's using the CAS+ keypad.

The P1-EVT2 (february 2006) and P1-DVT1 (july 2006) weren't mentioning a model name on the case, but were mentioning "TI-Nspire CAS+" in the OS about dialog box.
The P1-EVT1 does have a model name on the case: TI-Phoenix 1. Yes, no mention of the "Nspire" name yet.

And now for your viewing pleasure... ;D

Post by: Deep Toaster on January 02, 2012, 01:53:35 pm: Personally I think TI should have stuck with "Phoenix." It's a nice name.

Anyway, nice job on getting that prototype! Are its math functions complete? Just wondering.

The 4 historical math applications from OS 1.1 are allready here: editor, calc, cellsheet & geometry.

But the OS is quite incomplete... Lots of menus with disabled options or nothing behind.
Note that it's still interesting though, as compared to the CAS+ OS many things seem to be different... The RS232 bootlog should surprise us to my advice... More infos soon ;)

It's pretty cool, tho if they stuck with that name, teachers and etc might have been less likely to take it seriously b/c of it.
(even the font looks, um, "non-educational" :P)

You can view it in bigger dimension from the TI-Planet news:
http://tiplanet.org/forum/viewtopic.php?t=8630

Quite strange: the patents number are here, although they were replaced by 'X' characters in all later CAS+ prototypes, except the latest P1-PVT1.1 which was largely distributed to schools in 2006-2007.
Note that the patents numbers are different, too...
You can see the P1-PVT1.1 patents here for exemple:

I guess "Phoenix" was the internal code name, much like various software who gets a codename before being officially named.

Yeah, full-width alphanumeric. It's convenient in chinese because these characters have the same width as the chinese and japanese characters. (Normal characters such as those ones in this sentence are called half-width.)

(Also I can type like this because I installed a japanese input method and it lets me write like this.)

Post by: Freyaday on January 05, 2012, 03:30:08 am: I prefer separated arrows. Makes it harder to lean a key to the side and accidentally press another one. That said, the button in the middle renders it impossible to press more than one arrow key at a time with one finger. Where are all these prototypes coming from, anyway?
Also, will any of the released nSpire OSs even run on it?
Title: Re: Even more early TI-Nspire prototype discovery
Post by: Lionel Debroux on January 05, 2012, 04:23:24 am: AFAWCT, the CAS+ hardware has significant differences with even the hardware of prototype Nspires (those which use the latest prototype 1.1.x and 1.2.x versions, signed with development keys), so the released Nspire OS do not run on CAS+. The CAS+ (running OS version 1.0.x) even have a different communication protocol.
Yet, people keep scamming others, on eBay and other places, with those useless CAS+ models, and TI doesn't seem to be really eager to move in any way to solve the problem of scammed customers. The root cause of CAS+ items escaping into the wild by dozens, or even maybe hundreds, and being used for more than four years to scam customers, is TI not being careful enough about collecting CAS+...
Title: Re: Even more early TI-Nspire prototype discovery
Post by: critor on January 05, 2012, 04:39:21 am: If only TI would release the CAS+ OS, in order to to at least unbrick the CAS+ whose OS was removed by error/accident (by trying to upgrade through Menu+Enter+P for exemple...).

As the CAS+ OS is more than 4 years old and totally incompatible with the TI-Nspire, I cannot understand why... It's not like the CAS+ OS file will encrypt more critical informations than the latest Nspire CX OS...

The original CAS+ OS is removed.

And as TI has never released any CAS+ OS, your CAS+ is permanently bricked.

Post by: critor on January 06, 2012, 12:03:04 am: No we won't be able to, as Nspire Boot2 are incompatible with CAS+ Boot2.

Anyway, Datamath has finally released the TI-Phoenix 1 page with its test:
http://www.datamath.org/Graphing/Phoenix.htm

The page does include some information I sent after performing my own tests.

Have a look at the OS about dialog box:
(http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=44&image_id=354)

Yes, no mention of the "Nspire" name. It's a Phoenix OS !!!

Post by: critor on January 14, 2012, 01:20:16 pm: I've finally connected my TI-Phoenix 1 to my RS232 interface, and got the oldest Nspire bootlog! :D

The Boot1 is not a boot1 from TI. It's the free U-Boot 1.1.2 !!!

The Boot2 is from TI and takes much time as it does install the OS on each reboot, like on the P1-EVT2.

At the end of the boot, the Datalight command shel is active and let you discover the file system.

Hit any key to stop autoboot: 0
Is it possible to press a key before this counts down to 0, and get into the U-Boot Monitor shell? It has a command md addr len to display memory contents. There also may be a command nand read addr ofs size to read NAND flash into memory (also nand read.oob addr off size to read the extra "out-of-band" 16 bytes per page)

Edit: Unfortunately TI probably set the delay to 0 seconds, which would make it impossible unless CONFIG_ZERO_BOOTDELAY_CHECK is defined (and it isn't in the default include/configs/omap5912osk.h)

I can see the countdown but it's very fast.
I tried to press a key but it didn't trigger anything. I'll try again... Thanks.

Good point. Looking at the U-Boot source code, both input and output default to serial (and it's unlikely TI would change the input to be the calc keypad while leaving the output as is).
