Warning about OS 3.0.1 destroying calcs

[AngelFish]

If anyone who has a Prizm could answer the following questions, it would be greatly appreciated.
1. Can it simplify fractions like (1/2)+(32/7)=71/14?
2. Can it do prime factorizations like factor(221)=13*17?
3. Can it add nth roots like (3*root(2,8))+(5*root(2,2))=11*sqrt(2)?
4. Is input handled as well as it is with mathprint on the TI calcs?

1) Yes. However you need to use the a^b/c button instead of (1÷2)+(32÷7) to get your result. The calculator can display it in two different modes, so it may come out as 5(1/4) rather than 71/14 though, depending on your settings.
2) Not without a program. I've attached such a program below  
3) Nope. It can only return the numerical answer.
EDIT:
4) It's faster if that's what you're asking
It uses the same textbox style entry though.

Awesome, thank you very much! I think I'll look for a Prizm in retail stores this week.

Some T3 teacher said (probably without reading/understanding anything) we were responsible for all this, as we were using unauthorised OSes and encouraging their use on TI-Bank...

That doesn't surprise me... Soon, even TI-CARES might start blaming us for their own glitches!

This is just sad. Texas Instrument's quality control has been lacking for years, and it only seems to be getting worse. It amazes me how many issues they've had with the Nspire since it's release.

Yeh, about now some teachers have to be wondering what they got into by buying nspires and navigator systems for their classes only to find that OS 3.0 and nspire cx made all that obsolete.  I mean they could have went the safe route with 84 or the more recent Prizm and saved all those head aches. 

It looks like ti's quality control problem is that they don't have any quality control.  The business model seems to be "throw it out there, let the customer find out if it works, and fix it later."  Wonder what cx problems will be discovered when it becomes available?

I have installed the official release of OS 3.0. But I did battery pull more than 5 times while I was testing Lua programming. Nothing wrong happened.

My OS version is 3.0.1.1753 and Boot2 ver. 3.1.131.

3. Can it add nth roots like (3*root(2,8))+(5*root(2,2))=11*sqrt(2)?

Will do in math mode.

They ditched the Clickpads pretty early out, so now teachers would have to worry about multiple keyboard layouts for the TI-Nspire.

But I'm definitely sticking with System 2.0 on my Nspire. And my trusty old TI-86.

Did you make it run out of memory or something? If you just make a plain old infinite loop, you can exit by holding down the On key for a couple seconds.

[Munchor]

Will the press-to-test mode do anything about this?
Just an idea...

Never mind that, the calculator is bricked

If only we could edit the OS by bypassing the RSA, we could fix this

[GB]

They're just stupid. I guess they put blames on us whenever stuff happens.

Well... they'll see in a few years if we unite with Cemetech boycott of the TI-Nspire CX and that almost no game are being produced for the new OS and students decides to go with calculators that they heard there were games for, such as the Casio Prizm or older TI-Nspire calcs.

Do you REALLY run Windows 3.1???

I'm afraid so.

[mikehill2003]

I'm afraid so.

How old is your PC?

[Lionel Debroux]

His computer was, most probably, made during the first half of the 1990s
At work, last year, I reassembled several ISA cards into a motherboard bearing a soldered AMD 386 SX 40, plugged one of several 52 MB HDDs with DOS 6.x & Win 3.1... and for good measure, a trackball, whose drivers are on 5"1/4 floppy disks labelled "Logitech 1989". Most parts were made in the first half of the 1990s.

Wow... It's been a while since I've seen/used hardware that old.

The TI-Nspire Google group is now aware of the Omnimaga topic about the OS 3.0.1 upgrade bricking some calculators, I've replied to the person who brought the matter based on the information we have.

And subsequently, "Eric Findlay" made a thoroughly silly reply, showcasing his wide incompetence and untrustworthiness on the matter: that only the calculators which had been tampered with are affected, that TI put some code to detect tampering and brick calculators, and that if one uses the software in ways condoned by TI, they shall be fine.
Yeah, sure

[DrDnar]

Yeah, and CHDK and Rockbox void your warranties. Nobody ever bothers to ask the engineers whether what they're saying is even plausible.
