Wish I had a 89ti to test them out. I think I will keep my old 89 for the time being...

These updates add 89 Titanium support, not remove original 89 compatibility. They should work. I have a 89 with no batteries, so don't listen to me, however.

Michael, could you please add a reminder saying that some TICT programs were updated (once more) as well a while ago ? The previous news about TI-TiltMaze 1.21 didn't mention them. TICT-Explorer, TI-Chess and FAT-Engine are not updated yet though.
Thanks in advance.

Awesome! Now nobody will need to worry (as much) about certain programs not working. Also, that means we don't need a TI-89Ti-specific downloads section and people shouldn't have to make TI-89Ti-specific games, either. Right?

Some people will still try to put USB drivers on their 92+.

There are still quite a lot of problems with complex ASM programs, especially TSRs. I think there should be a defined 89Ti archive because the hardware is so different from anything else. Just the Left/Up switch on 89/92+ and the memory difference should be enough. There's one for 84+, and comparing 89Ti/89 and 84+SE/83+ leads one to conclude that logically there should be another archive. I know the rationale: no new BASIC functions. However, you could say almost the same thing about 82 vs. 83 and the hardware and ASM (tiams.h, USB, new memory map, etc.) are radically different.

Ahh, they switched the up and left keys? That's stupid. Why would they do that? That doesn't make any sense at all. Are they trying to make compatibility issues, or did they just feel that they didn't change enough in the new TI-89T, and out of boredom, decided to change the keys around for kicks?

That would screw up a lot of programs... (a lot use _rowread(), I believe) It wouldn't be hard to fix the key compaitibility in a program (just a few if statements), but for everything else...

But there's no TI-83+SE section. It has a few differences. However, it's nothing quite as major... I guess, when you put it that way, it makes sense to have a separate archive. I can just imagine the confusion caused for people new to TI graphing calculators, as they run into these compatibility issues in their programs. That just means more hate mail for the authors, so... yeah, I agree with you now. Good points.

I actually own both ti's the 89 and the 89Ti. Believe it or not the 89Ti is slower than its predecessor. Actually besides the 3x memory the 89 supersedes the 89Ti in just about any other aspect. Listen to me, if you do end up buying the 89Ti, test it against the 89 before you throw your 89 in a corner of your room.

The compatibility issues arn't really as bad as people make it seem...

lol, yes, it isn't bad if you consider not working at all acceptable. All of my programs that I have updated simply crashed on the titanium before i took the time to fix them.

Oh, crashing the calculator is all they do? I thought they would cause the batteries to melt or explode or something similar.

lol, i sure hope that's not possible!

That would be weird if TI had something like that built in on purpose...

For example, all programs made in C with tigcc and using grayscales shouldn't work if they are not ported or patched.

The language and the environment they use doesn't matter. It's even a bit worse in ASM, since most old kernel-based programs, which have been requiring HW2Patch for five years, and use awful hacks (absolute addresses to read/write system variables !!), are written in pure ASM. They are usually closed-source, and most authors left the community years ago, so modifying them is a hassle.

Grayscale doesn't work because unpatched interrupt redirection doesn't work on the Titanic.

I gave that example because most programs are writen with tigcc nowaday, and tigcc 0.94 is still one of the most downloaded file of ticalc.org. Of course there's been problems with other programs in the past, but that's not the point. And fot the old kernel-based one, I think you'll just have to wait for the next PreOs.

> I gave that example because most programs are writen with tigcc nowaday, and tigcc 0.94 is still one of the most downloaded file of ticalc.org.
I understood this, but your comment was incomplete. My point is that most programs written in ASM are incompatible with the Titanic as well.
> Of course there's been problems with other programs in the past, but that's not the point.
Of course it is, since they need patches.
> And for the old kernel-based one, I think you'll just have to wait for the next PreOs.
PreOS is much better than previous kernels, but it remains a huge piece of software taking some RAM and archive, most programmers and users do without it and will continue doing so.

But the kernel can apply all the patches for making an old program to work on a titanium, so it may be very usefull in an user's point of view ^^

"All" the patches ?? Patching a program to run correctly on Titaniums is very hard, since AMS 3.00 is another hack breaker. Many kernel-based programs didn't even support AMS 2.xx, only a part of those was rewritten...
In other words, I doubt that the kernel will be able to patch all kinds of crappy hacks... I'd not go as far as saying your post contains a lie though (although it's far from unusual in your posts on the TIGCC/TICT boards).

It's always a pleasure to speak with you, Lionel =)

it works very well if the kernel programs support AMS 2.0x.I haven't found any Kernel programs which don't work on Titanium with Preos 0.70.

They also work fine with GhostBuster and Iceberg. :-)

>>Grayscale doesn't work because unpatched interrupt redirection doesn't work on the Titanic.

Is that also why I can't get even patched TSRs (at least ones that do something-not like the sample one in the archives that prevents people from typing a lowercase A on April 1) to run?

It also says 'Error: Invalid Polar Complex.'

Did you install HW3Patch ?

> It also says 'Error: Invalid Polar Complex.'
Yes, most programmers were reported this error. Accessing the nonexistent ghost space seems to have wierd effects.

I installed HW3Patch. That's why I said the TSRs were patched.

HW3Patch is not enough, you have to run GhostBuster on programs. Read thread 'FAQ: Running C/ASM programs on the TI-89 Titanium' at http://p080.ezboard.com/ ftichessteamhqfrm13
(sorry, cannot post correct and complete link due to word size limit)

All of my programs in the archives work on the Titanium unless otherwise stated.
