Wow - I just inherited a PocketPC yesterday. I was desperately looking for something like this, and all I came up with was some HP emulators. For TI, looked like we either needed to install a DOS emulator ($40) and TI8xemu or install a linux distro :-). I was even thinking of porting one of the dos emulators myself.
Now, all we need is VTI Pocket Emu85, so I can ditch the old thing!

There are DOS emulators for free, try emulation9.com and click on the handheld section, or try palmsize.com

Thanks for the tip - but from what I saw, all the emulators linked were either shareware or paying. (But I can't really tell, as I don't read Japanese!)

This is all well and good, but would it be possible to have VTI on calc. And say emulate an 83+ on an 89? It would make it a lot easier for those people that ask me to use my calc. Not to mrntion to be able to play 83 games on my 89.

-Look there, a cricket. Look now, a dead cricket. W-

Someone is in the process of creating an 83+ emulator for the 89

Who?

MWM

I'm guessing *HE IS*....Not sure, but that's my guess...I think he was hinting at that...

I doubt it... LOL I think he was trying to say that somebody SHOULD emulate the TI-83+ on the TI-89... but the processors are so different... and I guarantee it would go slower than [inserts RCT's simile about TI-Connect's speed].

When I said "he" I was referring to angelboy...just clarifying if you didn't understand that...

Oooooooh. I get it... but still, I kinda doubt it. :)

Don't remember

I just found out who; it is slimey limey. I was reading his website and he mentions something about it.

MWM

That's old. I'm not doing it anymore.

Hahahaha- I mean, yeah, that's gonna be cool.

I think it would be a much better idea to scrap the whole on-calc emulator business and use a better, faster system. Instead of writing a program to interpret foreign code on the calculator (slow & difficult), they (whoever 'they' are) should write a computer program that converts the ASM from one calc's format to another's, so it can be run normally on its new system. Admittedly, there would probably be some things that would be difficult to translate exactly (differences in screens, ROM calls, and whatnot) and would require slower work-arounds, but the speed differences between an 83(+) and an 89 should compensate well enough.

P.S. The next idiot I hear bragging about writing a program to convert BASIC programs from one calc to another is gonna get SHOT! ;)

Hey! Guess what? I made a program to convert BASIC programs from one calculator to another! Haha!
Just kidding...
But now that I think about that, it might be a little harder than it seems because some calcs have functions that others don't, and some have parenthesis while others don't (TI-82: int , TI-83: int( ).

Anyway, that's not really important, you can do it by hand just as easily.

Converting ASM programs from calc to calc (what you said) would be nice, but the only problem would be inflated code, or really slow code. But hey, if it runs....

Too bad no_one, someone beat you to it. William White, I'm coming for you...

Check out the link
It converts TI85 assembly to TI89/92/92+ assembly

Cool! But the $64000 question is: does it work? I don't have the time to care to find out for myself.

By the way - do you know of any actual projects to convert from one TI-Basic to another? I've got a very long-running project of writing a TI-Basic interpreter for the PC, and something like this might be very useful for me - that way I could standardize syntax. Or maybe they have already developed a grammar and parser for the language, which is also good.

How about an 89 emu for the 83+? (Or the 83- of course ;))
Then we'd *finally* have symbolic integration for the 83 series!

No, I don't think that it would be possible for that to happen. Mainly because there are not enough pixels on the 83+ to emulate it where it looked half-way good.

Well, the TI-83+ has nowhere near enough FlashROM to even store a copy of AMS (in addition to the TI-83+ OS, which as far as I know nobody has found a way to overwrite yet). Even the TI-83+ SE is probably too tight on memory (especially RAM) for a TI-89 emulation to work. And then of course, as you said, the screen size is an issue. And even if someone managed to solve all those problems, the emulator would be slooow, veeery slooooow...

Emulating a Z80 calculator on a TI-89 would be more feasible. But even that would probably run slow. The GameBoy and the ZX Spectrum have even lower-clocked Z80s (well, the GameBoy CPU is not really a Z80, but it is very similar) than the TI-85 and still can't be emulated at full speed on the TI-89.

"the TI-83+ OS, which as far as I know nobody has found a way to overwrite yet"

It can be done, but it requires an action illegal under the DMCA.

WHOA!!!!!!

The DMCA prohibits writing software for your calc?!

I thought just selling TIOS or something.

This is really serious-it would be like the NAFTA section that prohibits 'expropriation of future profits'.

No, it doesn't. What the DMCA prohibits is circumventing security measures.
You see, when you send a new OS to your calc it is verified by means of a digital signature. (This signature proofs the OS was approved by TI.) It is not feasible (and illegal) to forge the digital signature. However, Michael Vincent found a way to circumvent the check. Because of the DMCA this circumvention is illegal too (but now it's at least faesible to load your own OS).

Do you know if MV has found a way to write to the FlashROM on the TI-89/92+? I have only a 92+ (and an 86, but that doesn't have FlashROM), and I would like to put my own OS on it (I'd start with Linux, of course :-).

Actually, the reason TI sent him a cease-and-desist (or whatever it was) wasn't because he wrote his own operating system. It was because he was trying to reverse-engineer the existing one, which is illegal. I've read the DMCA (yes, the entire thing) and his creation of a totally independent operating system would be 100% legal.

Good.

Yea, remember Michael Vincent's OS? He managed to load it to his calculator.

I know someone in the community (probably shouldn't say who, lest he get a flood of e-mail about it) who has figure out how to send the TI-73 OS to the TI-83+, and vice versa. The signing process can be circumvented, but as long as the DMCA is in effect, don't expect to find the info freely available.

well to talk of all this game boy stuff, couldnt some one write a gameboy original emulator for the 89 or sumtin, dont those have enough pixels, would it really be that hard

Yeah, I think it really would be that hard. :( The gamebody is a z80, right?
