Internet here I come... this is even easier than the ricochet modem idea cause i have a cable and don't have money (funny how that works)!

umm mabey i got a little excited up there...
does anyone know where to get an executable rather than the source??
I don't have borland

thanks (me happy now) :)

I may sound totaly stupid after this comment is finished, but i thought id give it a shot. How possible would a software based modem be in a calc. using a very minimal ammount of extra hardware and the calculators link cable. I have no clue how possible that would be, or if it would even be of any use. tcp/ip stack with a ppp protacal with software based drivers to send data over the link cable through the phone system to your isp. I know it would be slow, but it could come in usefull if your away from home, no computer, and need to check your email.

actually, the calculator linkport has a burst transfer rate of 57600 bits per second. the bottleneck would be in the pic microcontroller in the gray cable that converts the signal between ti's proprietary link protocol and industry standard rs-232 computer serial port protocol. that typically restricts transfers to somewhere in the range of 10000?-25000? bits per second. if someone builds a homemade version of the gray cable with a pic microcontroller that can support the burst rate of the 89's linkport, we will get transfer rates equal to the best that dialup access can reliably sustain.

Is there a TCP/IP suite for the 92+ series?

Thanks..

screw the executable, anyone know where i can get an 89?!? heh, /me wets myself. I've been happy with telnet83 for the 83 but this just amazes me. good work!

If you have not seen from sample autoexec.net file,

IP address of PC server is 192.168.0.1

IP address of TI89 is 192.168.0.64

Hi, where do i get NOS (the link gave me a bunch of junk) and how do i run autoexec.net?
Thanx,
Ryan

In the run window...
Start > Run
type C:\spool\net.exe autoexec.net
this will run net.exe and load the .net file script
i had to guess around at this, but i got it to work
hope this helps..

Now if only I had a gray link I could get on irc from my calculator. BTW this dosn't work with winmodems does it? I know some are DOS compatable, but i think that only works in a DOS shell from windows. "WINMODEMS BAD"

Hi! I'd just like to ask one thing... Would it be possible do use this with a radio link... That would be really cool!!! If it is, where could I find the schematics to a radio link that works well?

given that you find the schematics for any radiolink comma all that you would have to do is build a base unit that has a pic microchip that converts ti apostraphe s proprietary link protocol into rs hyphen two three two computer serial port protocol at a speed of at least five seven six zero zero bits per second period

note colon the linguistic style in this post was inspired by former co hyphen guest hyphen logger on nickd dot org

why didn't i think of that?

good question. its also good to see that you deciphered the written punctuation words in place of their respective characters. i wonder how many other people deciphered it:)

I don't mean to put a damper on the situation but what is the point? Why would you want to have internet access on your calculator? If you have to be plugged into your computer anyways why not just use your computer to access the net?

The point is that it's m4d l33t to just be able to do this, even if it isn't practical.

This is my opinion, but I feel as though this is like a stepping stone to greater things. The calc will have to be able to get on the net with aid before it can go alone. ou must crawl before you can walk.

I could think of a few reasons...

It's 'elite'. Things like these show how much you can push a calculator... (who knows, someone might port it to gameboy ;x)

If it ran at a decent speed, It could be used for simple games. _simple_ games.

It's a novel idea. People like shiny things.

Why not spend your time on making something cool that is actually useful. As for the stepping stone idea... I don't think this is a stone you want on a calculator. There is no way that calculators with wireless internet are going to make it. TI already hates the idea of their calculators being know as game consols. Do you actually think ccalculators with Internet would ever be allow in our schools?

Hey, I found it cool and usefull (I do not even own an 89). Things like these are always nice to see...Heh, It is pretty 'm4d l33t'!

Anyways, this is just a thought... I find that working with the ports on any calculator to send data over a link cable is a pain. I'm betting that it wouldn't be much of a problem making his TCP availible for calc-calc transmissions (I wonder if the docs mention anything...).

Now unlike most TI users, I don't hate Texas Instruments. However, I disagree that TI "hates" any publicity that sells calculators. Whether they be known for integration or recreation, TI calculators are going to be bought at a greater rate if they're famous for anything. So I doubt TI dislikes one bit the fact that their calculators are mini-gaming-consoles. Not that this is off-topic or rambling or anything, but I just felt like adding to the discussion :-)

>>Why not spend your time on making something cool that is actually useful.

Good idea. Does this mean you're going to stop using your time posting complaints about an innovation that many find cool, and you'll start coding some programs?

I actually have made some programs for the calculator. I have only posted 1 on Ticalc because I am to lazy to post the others. I made a little program for the 89 called C_helper.
I don't know if TI wants their calculators to be used for games in fear that schools will stop using them. I think the TI calculators are already plenty well known. If you have been around here long enough you know that TI has put up efforts against the gaming idea. Of course this is all just my speculation.

If TI doesn't want their calculators used for games, why do they have games on their web site?

Well, TI gives some crappy games on their website, about 5 or 6 basic games. TI is really more of a "control freak" who wants to control and monitor all of the TI educational community and the TI developer's community. Overall, they support the educators strongly, and are rather apathetic to the neads of the developers who do not give TI royalties.

oh, i beg to differ. at my school, there are actually two people that use Palm VIII's for their "graphing calculators". They may not be allowed on standardized tests, but they work... and it's my opinion that they're probably getting a better education by having to do a bunch of stuff by hand instead of punching a few buttons.

Uh hmmm you obviously don't have a clue of what your talking about. The software on the Palm Pilots that graphs and does other calculations is nothing compared the the Texas Instrument calculators. But that is besides the point. What I said in my previous post is that calculators with wireless Internet connection are not going to be allowed in schools. So what does that have to do with Palm III's?
And you say that you get a much better education by pressing a couple of buttons? That is completly false. You learn next to nothing from pressing a couple of buttons then you do from learning how to do it! I know this how? Hmm well just common sense and experiance. I have had a TI calculator for 5 years now, ranging from a TI85 to the TI89 that I have now. By just poking a couple of buttons all through highschool I didn't learn jack compared to what I was supposed to learn. Now guess what happened. I am screwed in college because I don't know all of what I am supposed to know. In college you can't just poke your buttons and show the teacher like you can in High School. You have to show all of your work or you don't get jack credit. I am sure there are other people that could tell you the same thing.

hrm... would a TI 89 emulator be concieveable on a palm? There is a Gameboy emulator!

that'd be cool... just toat around the ol' handspring

[goes of into deep thought on the subject, then realizes he knows nothing about emulation]

~Jake B

I do not know about memory capabilities of palm. TI89 ROM is quite huge. Also TI89 uses relatively fast processor (Motorola 68000 at 10 MHz), so emulation can be quite slow, if possible at all. But interesting idea can be remote TI89:

1) On Windows machine (server) put VTI
2) On the same machine put WEB server
3) Create page with buttons that execute CGI scripts described in 4.
4) CGI sends keypress to VTI, and returns HTML page with GIF from VTI screen and buttons.
5) Web browser receives page.

This will not be useful for playing SMQ, but if you need to solve some integral while you are on Internet using PC, NC or Palm, can be.

the deal is to port Derive to Palm... dont need an emulator.

That would be a very good idea. Derive isn't what the 89 is all about, the 89 uses other things, like modifications from TI, a TIOS which holds the derive functions, and other stuff. Derive can't run games. But with Palm games, who needs 89 games?

It will not be so impossible. The ancestor of Derive, Mumath is available on Internet with source.

www.retroarchive.org/cpm/
Select Miscelaneous software
file mumath.zip

Here you will find the source of the hardest part of job, symbolic algebra and calculation with very long numbers.

The rest of the Derive package (function graphs and numerical analyse) can release every better student.

CP/M was old 8 bit operating system, started with developement in 1974, and widely used up to 1989. However some modern software has roots in CP/M. I think that Tezxas for TI-92 Plus can be easely modified to CP/M emulator, allowing it to use CP/M software. The most interesting are programming languages: You can test your examinations from Fortran, ADA, C or COBOL on your calculator.

are you talking about Liberty?
It is a very stunning piece of work, all for only 16 bucks.
But, it recommends an overclocking utility to get decent speed with most games. Afterburner overclocks it to about 40 mhz, about the MOST speed you can get on a palm. It may be fine with a 4 mhz gameboy, but it be MUCH harder to emulate a 12 mhz ti-89 on a palm. There are some other shortcomings of the palm that limit emulation. Most obious are the keys. The 89 has 50 keys, the palm has 6. Sure, you can use the touch screen, but remember that over 80% of the screen has to be used to emulate the 89's screen. Then, you can use the grafitti writing protocol, but it would be EXTREMELY difficult to write in the numbers, sine, cosine, sq root, etc.
The 89 emulates slow even on a 200mhz pentium with VTI! Guess we'll have to wait for a palm XV or something

I must point out that the calc's wern't designed to be a substitute for learning, they are supposed to aid you in learning. As of right now, i'm doing better than i ever was. This is all thanks to my calc. I actually TRY to learn, and try to understand. My calc is just there to make efficent use of my time. I don't have time to get graph paper and rulers.

Speaking of Palms, now all that has to be done is for ticalc.org to make a Mobile-Friendly™ version of the site!

whaaat??? you say it's shiny?!!
sign me up!!

ooh, hang on... i don't have an 89...

who cares!! shineeeeeee!!! 8)
