Now to get a pocket PC...

Yes, now an excuse for me to buy a new toy.

now all I need is an emulator for a pocket pc...

lol have one emulator run another

[on pc run the pocket pc emu, then inside the pocket pc emu run ti 89 emu???]

yea, now all we need is a pc emulator for a 92, then put the pocket pc emulator on there, then run the 89 emulator on there...

Sorry to break your bubble, but the TI-68k can only allocate blocks of <= 65535o ( =64Ko). Thus, you need at least 10 blocks of RAM to emulate even a 640Ko pc. But that actually has 1Mo (=1048576o) of RAM, so compression is likely required.

As you may be able to tell, I'm switching from bytes to octets. They're more portable.

New word! Compressino - one basic unit of compressed data. (one compressed bit?)

You can't define one unit of compressed data.

I have one partition of my hard drive that uses drive compression, and the ammount of space a file takes up on the drive varies wildly depending on how efficiently the source file uses space.

An MP3 absolutely cannot be compressed further
An MPEG4 AVI can only be compressed by less than 5%
A folder full of text files can be compressed extremely well...

A standardized unit of compressed space would not be very accurate, as the ammount of data that could be stored in that space would vary depending on the type of source data.

Say what? How's that an excuse to get one? Your mom could just say to get an 89 instead (which is a better choice indeed :p) than that..and it's definitely not an excuse if you've already got an 89 lol.

PPC's are such a waste of money...go buy an expensive gun scope or something lol

I hope this will work on my ipaq3600...
Anyways, this seems like a very interesting project.

A TI-89 is like $400 cheaper than a PDA and does more. I know I'm ranting into the wilderness, but why would anybody buy a Pocket PC?

Because they already have one?
(Note: people who already have a PDA, and don't feel like buying an 89, can't use this, as the ROM is copyrighted.)

Yeah, I don't think that many people who have a Pocket PC, but not an 89 will hear about this because they don't come to this site. Also, if someone has a Pockect PC and a calculator, what good would it be to have an emulator on the PDA? Its like having a slightly more unstable version of what you have in your other hand. This is still a good development, and its cool that someone made it.

I still think it's a good idea

To quote many well-known films, "You aren't paid to think."

Just because it's a *cool* idea doesn't mean it's a *good* one. Spending $200-$800 on a PocketPC and $150 on a TI-89 just so you can have a buggy TI-89 is a ridiculous concept. People in the "real world" (i.e. people such as myself who have learned how to handle finances) will understand this.

The concept may be ridiculous but its not about emulating a ti-89 on a pocket-pc for practical purposes, its about doing it to see if you can. At least thats the way it would be for me.

Great point! that's exactly what I myself was thinking. Who cares how "good" a program is. It's the CONCEPT that can be used in more advanced programs that makes the program itself good (this is my opinion)

The problem is that the concept isn't NEW, or even INNOVATIVE. It's just another emulator for another system on another computer. The idea isn't really that exciting. Now, if we could have an emulator for, say, a Commodore 64 on the TI-89 or TI-83+, then I might say it was worthwhile. However, if you are ever in a situation where getting the equipment to run an emulator for a device costs more than the device itself (and that was the only purpose you bought the equipment for), you are wasting your money.

bizpile: "its not about emulating a ti-89 on a pocket-pc for practical purposes, its about doing it to see if you can."

You can do ANYTHING to see if you can. For example:
Try cutting off your fingers. Do it to see if you can.
That's a REALLY bad reason to do anything.

Why do you have to be so hostile? Click the link. Maybe it will calm you down a bit...

How was that interpreted as hostile? I was simply stating that their reasoning was flawed (that you should do something simply because you can) by using an extreme example. I'm not angry, upset, etc. I just wanted to point out the problem with their logic.

Yea, I'm with you on this one. I really don't see the point. But about the copyrighted ROM thing, can't you just download the hex file from the TI-site?

... the hex file?
I assume you mean the AMS... and yes, you can. However, I think that in the EULA you have to agree to to download the AMS, it says something about using it without owning the calculator, or some such stuff. It's too late for me to go check.

I've just read the EULA, and it says nothing about owning a calculator. They probably just figure that anyone who downloads it would put on their calculator.

Very nice!

Calm down dude!
So you think that the entire concept of VTI sucks? I mean, where can you buy a computer for less than the price of a calc... "But a computer can do more than just emulating a calc" you say. Read my previous post (second in the thread), maybe people already have a pocket pc, and would like to emulate their calc on it so they don't have to carry two devices everywhere.
Of course you can do anything you want, but in the case of writing Pocket VTI, you could actually learn something from it. Maybe you have to research the calcs hardware to emulate it properly and find something nobidy else found out before. (Yeah, cutting of your fingers could learn you not to play with knives, but I really hope you see the difference.)

WHY DOES EVERYONE THINK I SOUND UPSET?
I'm not! I'm just pointing out logical errors by using extremes! If the cost of some activity outweighs the gain, then it's probably a bad idea.

You make the argument that PocketVTI gives people an opportunity to learn about the hardware of the PocketPC. How is this so, when all they're doing is using a pre-made emulator? Sure, the author had to do some research (and he learned something in the process), but everyone else is gaining about as much knowledge of the PocketPC as your average gamer gains from playing their GameCube (or whatever).

Probably because you are shouting a lot.
I did mean the author. Have you thought about the fact that the author can share his new-found knowledge with the rest of the community?

Omg...hush already, you words are carrying with them a aura that hurts the animal mind of doing out of desire...*raises paws to ears* AHH! MAKE IT STOP! AHHH!

LOL... you haven't been here in a long while...

In other words: Nobody is really gaining anything worthwhile out of this other than the author, who gained experience in programming for the PocketPC and learned a lot about the TI-89.

So now the TI community reaps the benefits of more and better programs.

The other point is that nobody really gives a crap if its worth it or not. If they want to do it, let them do it. Who cares? I dont. If they have the time and patience to mess around with it then so be it. It really isn't a matter of whether or not you gain anything from it - it is just the sense of "hey i did it" that matters to the author, and to the users it is probably just the curiousity or the fact that they can do this that matters. I understand what you are saying and agree to a certain extent - but it's not a big deal. Anyway, whatever.

I've been looking for somthing like this for a while. I have a TI-89 and an IPAQ 1935. I carry the TI-89 in my bag and have it with me most times, but my IPAQ is much smaller and more accessable for me.

This provides me with my TI-89 all the time without having to carry two devices around. Still need both, but don't have to carry the TI-89 all the time.

i dunno, i kinda agree with jrock, and with your post, it doesent have to be innovative, you cant base some ones reason for making a file on your own belifs, i may not be a very good programmer, but i know i dont let a few people keep me from attaining my goals..., why does anyone have the right to cut down someones elses work, maybe you dont want to carry around the 89 and a pocket pc their both kinda big in the pocket...

You have two pockets

Uh..... maybe you have a TI-83+SE in the other pocket? LOL

i love my 83+se, i think it has the easiest and most staitforeward menus, plus you always see more stuff devoloped for it, even though it is not as advanced

I like the TI-89 menus :)

And I favor the TI-85 menus!

NOOOOOOOOOO!!!!! lol

Well, they're both kind of similar, at least in that they are an actual menu at the bottom or top of the screen that doesn't interfere with the text you type. As opposed to an 83, where the menu is a page sized list of options.

Actually, on second thought, the 85/86 isn't fair to people with poor eyesight. Err, no, the text on the buttons is about the same size as the text on the menu screen of an 85/86.

That means, TIs entire line of calculators aren't fair to people with poor eyesight. Someone should report them to whoever was responsible for there being a handicapped parking space at the karate center I used to take classes at.
