I think TI is discontinuing the TI-83. You can't buy it from their online store. The funny thing is you can still buy the 82...

Hmmm... I understand that TI discontinued both the TI-82 and the TI-83. Radio Shack has TI-83's for $99.99. I have seen the newer TI-82's at WalMart. Now here is what is different. The case and cover has changed. On the TI web site, if you go to the correct page, tells of the change in the case design. The link port has been moved from the bottom to the right side, looking at the calculator from the front. Also the battery covers has changed. Instead of being a small rectangular cover it is now the whole bottom width of the calculator. Also the CR1616 battery is no longer held in place with any kind of cover (except under the one big cover holding the AA batteries in place.) It is just popped in place on the left back. Now I bought a second TI-82, but it did not have this case change. The TI-83 I bought off e-Bay was this newer style case, same newer style case as what Radio Shake sells. BTW I hate the new battery cover. It is very difficult to open. Very difficult. (I had to use a screwdriver to push the tab so it would slide open.) Also I had to order a TI-83 plus full manual (off e-Bay) for my TI-83 plus Silver Edition. The SE comes with a thin manual. But the up side it has a built in manual catalog application program in place of the larger manual. Now that I have also gotten two more TI-86's (at 20% and 30% off at a closing K-Mart, where I got my second TI-82 and TI-83 SE) One of them (86's)just may get copy of this chess program.

No TI didn't change the battery size from AAA to AA, I just forgot to type one of the A's.

So... I'm confused. How many calculators do you own?

WAY more than any normal, sane person should (then again, I don't think any of us are sane, normal people).

I have a 73, 81, two 82s, two 83+s, two 83+ SEs, a 86, and a 89...

yes, but your not a normal, sane person either. Your a super-duper program man who should be working hard to port this to the 83+ *hint hint*

This is a little off topic, but I've not gotten a response from anyone at Detached Solutions, so I'll ask you. When does the next version of Mirage OS come out, and will it fix that annoying bug where it crashes when you run basic progs?

Hmm..I'm sort of busy, and before I was to ever port something, I have a no-AI chess game for the 83+ I wrote a while ago...It'd be simpler for me to add an AI than to port from the 86 (in my opinion). Note that the aforementioned statement implies absolutely nothing about me doing anything with chess in the future :).

The next version of MirageOS will fix that bug, but it won't be coming out for a long time. Jason Kovacs hasn't completed the GUI yet.

just add the ai from this one

did you upload the chess game?

You mean it crashes when you quit? It merely does that because the programmer didn't put "Stop" at the end of the program.

no, it doesn't crash when they stop, it crashes when I run them...I think it is actually whenever the program hits a point needing input. Highly annoying.

And Michael - is Jason updating the Graphical User Interface or what? Because if not, couldn't he just reuse most of the coding from Mirage OS 1.1, and just correct wherever the bug is?

The GUI was going to be rewritten I think. The problem wasn't in the GUI anyway, it was that the vectors for running basic programs changed on OS 1.13 and 1.14 and MirageOS was expecting 1.12.

Well, I figured it wasn't in the GUI. Ahh well...now I have a project of my own...I'm going to use some assembly utilities and write a basic GUI so I can quickly run all my basic programs.

well, I WOULD do that except someone stole my 83+ SE. GRRRRRRR!!!!!!!!

ouch!
he who steals my SE goes to small claims court...
w00t!

whoever steals my SE goes to small claims court, probably. Either that or I just administer a personal and VERY thorough butt wuppin'...though that would allow them to press charges of assault with a deadly weapon - I take martial arts, mind you, so I'm a walking deadly weapon ;)

It is more annoying than anything else....my parents ARE buying me a new one

SO WHAT???

WHOEVER STEALS MY SE IS GOING TO THE SUPREME COURT AND HE IS GOING TO PAY FOR IT BIG TIME...

ummm...never mind

Well, of course he would pay for it, unless you're willing to cough up fees for a hotel room, probably airfare, gas or public transportation...etc. It takes a lot of money to get to D.C., you know.

Or maybe you meant he would have to pay for the Supreme Court. Now that's a whole different story. Let's see, there's 9 and they get like what, 500 grand a year? Then there's the building. That's gotta be several million dollars without the expensive furnishings.

...... Electric flyswatter???

Yes?

Do I dare to ask... why??

One thing I would like to see in MirageOS v2 is the option that asks if you want to sort the programs or not after each RAM clear/you first load it.

You can do that, turn off auto-sort. Then if you want to sort at any time, do so manually.

Where's that option?

Under "MirageOS Main Options"

you probably don't get a dollar a week alowance like me.
I have an 82 (free from a graduating senior :), 83 (my first calc), 83+ SE, 89

Well, my user name handle is MadProgrammer. And then I use my real name. That is Mad.

Abacus good; CASIO BAD! Junk all Casios!

Generally Casio calculators are better than TI. For example:

The following problem:
1.000000001^1000000000

On my under $8.00 Casio
2.718281827
On my TI-30X SOLAR (typically about $14.00)
2.71919279

HEY!!!

IS THIS SITE ABOUT TI's

HEY!!!!

IS THIS SITE ABOUT TI's OR ABOUT CASIOS!??!!?

w00t!t00w

liar!
Evil!
casios gave wrong answers on a test (9^9 = 81 or something like that). I read it in a newspaper (not TI Weekly)

It was about a year ago on the Florida standards test. Students were given Casio scientific calculators to use. For some reason, if 3 x 3 x 3 was entered very quickly, it gave 81, which it obviously isn't.

Are you sure about this. If you enter 3 and press x^2 twice you should get 81. On Casio calculators this is also done by 3 x = x = which also should give 81. So if the constant feature on a calulator also repeats the function against the answer instead of having 3 as the constant one has times (x) then the result will be 81 again. Only if 3 is the constant being multplied and (not the times function against the last result) will you get 3 x 3 x 3 = as 27. My older Casio with the k constant feature, has a broken battery cover, and at this moment I don't know where it is. So I can't test it to see how that might have caused the problem.

Actually, they were 4-function calculators. Our school used some generic model, but they were pretty sturdy. Then, most of them were lost and the TI 4-functions that weren't lost were all broken, along with all the TI math explorer scientifics, so my math teacher no longer has any calculators.

Well checking a 4 function calculator that I have handy. 3 x = 9 = 27 works fine. 3 x = 9 x = 81 is also works correctly. This 4 function calculator is a little more than 4 functions in that it has a memory, square root and percent. But other than that it works like any other standard 4 function calculator that I have used. If you are running windows 9x, there is a calculator which has the standard 4 functions. But it too has memory, square root and persent. [ Though I prefer the scientific version of it. It does PI to 3.1415926535897932384626433832795 And you can cut and past the answer to a text as I did here. It also does large factorials too. It took some time but it did the factorial of 10000 as 2.8462596809170545189064132121e+35659 My TI-82 program gave me 2.846260e+35659 by approximation. (This is the same program that I fixed and uploaded for the TI-83) ] So when are we going to a chess program for the TI-83? The charactor screen width is 16 columns x 8 rows. The TI-86 is 21 columns x 8 rows. Only the display would have to be re-designed. Except also for any major ROM call differences, and general addressing differneces. Other than that, the same program should be able to be converted. Given the logic and methods of play. And it would run faster on a TI-83 SE.

what your're talking about is basically all you get now as 4-functions go. I have only seen a couple, if that many, basic calcs w/o sqrt and mem.
It amazes me that some people wouldn't be able to tell 3^3 from 3^4, which is what happened when, on the casios, someone pressed 3*3*3=. I don't know they just didn't do 3*== to do it, which is a lot easier.

also when porting, the 83 displays the screen differently

Well all the TI graphing calculators that I have for
1.000000001^1000000000
as the answer 2.718281827

Only since the TI-55 II and TI-54's have these bad TI ROMs been in existence in various degrees of error. BTW this 3 place limiting accuracy was in fact document with the books that come with these earler series of calculators. What the worst part was, is the membrane under the key pad would go bad. My TI-54 is totally usesless because of this defect. What was neat about it you could do complex numbers starting with a square root of a -1 without getting and error.

For God so loved the world...

Well, besides the ones listed on my bios page. A TI-68 (programmable but not graphing.) An HP48GX. Not to mention other Scientific calculators. Two HP 6S's one HP 30S. Two TI-30X IIS's one TI-30X Solar. A TI Explorer Plus, A Casio fx-260SOLAR. Two Rockwell 63s scientic sliderule's. A couple sliderules, the slip stick batteryless type. And an Japanese style abacus. The difference between a Chinese sytle from the Japanese, is that the unit 5 beads the Japanese abacuse has only one unit 5 bead with five unit one beads in each row, where as the Chinese style has two unit 5 beads at the top of each row. Then there are the few others that I failed to mention. But then there is (I hope still at my Mom's place, except my Dad had used it for parts) my General Electric Analog computer. Had that one when I was a teenager.

Radio Shake... heh.

kinda like me

Well I spelt it (shack) correctly the first time. LOL. (And a spell checker wouldn't have caught that ether.) It must be some kind of Elvis syndrome being ". . I'm all shook up." Now, who is going to write that AI English program to help in English class to properly parse a sentence.

You know, I was actually doing that at one point, but I kept getting tripped up over prepositions.

kinda like a milkshake

i think you got it backwards

^ see TI features page on the TI-83

TI calls the new case restyled.

^ see the TI-82 features page.

Like the TI-83 calls the new case on the TI-82 restyled. The three main changes are: The cover has an added notch or clearence place at the top of the top of the calculator to make it easyer to push the cover off. The I/O link port is moved from the bottom to the right side. And the battery cover is now the whole witdth of the calculator (and is harder to open to place or change the batteries.)
