I think that I may have found another minor change in this version. By accident, I used more than one negative sign infront of a number. Instead of giving an error, the two negative signs negated each other. I tried this again with more signs, and it works.

Yeah that was part of 2.30 also. I just tried it.

it seems like TI is trying to get people to buy the new and "improved" calc modles by adding features that they could have just as easily added to the older calcs to the new OS's which only work on the new modles

This works fine in OS 1.16...

Looks like it boots faster, when using 2.30 it took my calc almost more than 1 second to boot up, before 2.30 this didn't happen, and now under 2.40 it boots fast again.

I am assuming that I probably misundestood your comment. Are you saying that the TI-84+SE's OS version 2.40 boots up faster when you turn your calculator on (by default RAM and/or Flash ROM) or is is the same speed (booting up) when using OS 2.30?
If that's the case, by approximately how much faster does it boot up as compared to 2.30? I haven't downloaded OS version 2.40 because of some issues on this message board (talking about OS version 2.40).

Thanks.

It's curious how many people are saying they don't want to install this on their calculators so as to "protect" their calculator from evil teachers. Realize this is actually a _good_ thing for those who want to keep your programs and such.

If you have a teacher who is adamant about preventing cheating (which IMHO is quite reasonable), without this new feature the only thing he/she can do is fully clear your memory. Generally, people hate it when this happens. Now, the teacher can lock your memory, making sure you don't cheat, but once you're done with the test, you can unlock it and everything is back where it should be. Your new game that you've spent months working on is all safe.

See, this is actually a feature where everybody wins. The teachers can lock down calculators, while still making sure that the students are happy as they don't have to endure full memory clears.

of course, it deletes all my groups which is where I keep ALL my programs in order to conserve RAM

I would agree with you completely, but the fact that it deletes all groups is annoying. Also, it gives us something to hack. ;-)

Hmm...didn't notice that though. TI should fix that....

if they did something like that for the V200 we could probably use it on the SAT, that would be good news for me cuz i only have a V200

Ummm.... No. The reason the V200 cannot be used on the SAT is the QWERTY keybaoard; it scares them. (I do not know, maybe easier to program on the fly?) So that idea is out.

As far as the ACT goes, you could not use it because of the same reason you cannot use the 89 -- the CAS.

> The reason the V200 cannot be used on the SAT is the QWERTY keybaoard; it scares them. (I do not know, maybe easier to program on the fly?)

Yeah, the QWERTY keyboard is rather scary, but not for programming purposes. The test writers are scared to death that people might type the questions into their calculators and then maybe sell them to test prep companies. A QWERTY keyboard allows for much much much faster typing.

Yeah, I guess. But it is my opinion that it is just as akward to type on the 89 as it would to use the thumb board on the V200/92(+).

-W-

Yeah, that particular restriction does seem pretty pointless.

thats kinda pointless, cuz i can type faster on my TI-83+ than on my V200 (since its hard to arange my fingers on the tiny keys), the 83+ os just got upgraded, i hope they didnt go and put this lock mode on there

I am glad that I saw this. If I didn't I probably would have missed this, and might have seen later a OS v. 2.5 or something.

Quick! The TI-83+ OS has been updated!

YES, i already downloaded it, yet to see a keyhook tho

I called ti about the new operating system... They said it prepares the calcs for a newer version of the app called testprep.

And it adds the new manual lock for the 84s

Um, I think I fount something else that changed.
I always relied on the LCD Fix program to play ZTetris. After I installed 2.40, The graphics have no problems without the LCD Fix.

oops. Doesn't work anymore
sorry.

I was trīng to update mij 84+ and suddenly it stops. When I turned it back on and this is on de screen:

Waiting...
Please install
operating
system now.

When I trei to connect my computer doesn't regognise te calculator. Then this appers on the screen:

ERROR!
Press any key to
turn unit off.
Then turn unit
back on.

Does anybody have an sugestion what i shoeld do?

Well, this happened to me about a year ago.
What i did is i researched it on the internet for a couple of hours, then i found out how. If i remember correctly, if you try to send the OS to the calc, it says it can't find the calc? well, i think you're supposed to hit retry or something
i'm not POSITIVE, but i'm pretty sure its something along those lines

Alright, I jacked up my calc to figure out how to solve the problem, and here it is:

I have the latest version of TI Connect.
If you look in the application folder, you'll see a subfolder called 'TI Connect' open this and run the file 'TIOSDownloader.exe'.

Follow the instructions and your calc should be good as new (literally, because all programs will be erased!). In the second screen, you have the choice of using a black link cable, a silver link, and a usb cord.

Good Luck

i just used the OS they provide with the Ti Connect, its working for me......

darn it....if your calculator shuts off, it starts over.....it did that for me...

I tried that but it wouldn't transfer. I even took the batteries out and reinstalled them like it said. Any ideas?
