this sounds pretty cool, which I had an 86. I wonder how it compares with TI-Chess from TICT?

It probably stinks compared to the 89 game, but this one is a lot smaller in size than the 89 tichess game...

If you download it, you can find a document the author wrote which compares it with TI-Chess, and concludes that Chessmaster 86 is better. However, to me it seems that TI-Chess is actually better, since it plays with a much higher skill, and is also faster. Of course, if you actually care whether you win or lose, then Chessmaster 86 might be better for your ego.

you could port it to the 83(+)!

Watching the CPU battle it out against itself is kind of funny ... right now, there have been 400 moves, and counting, and the computer has kept the same positions since about 80 moves ....
What happened to that rule that if the same positions are repeated x amount of times in a row, the game is a draw?
Now I can't exit the game ... and the computer isn't going to be checkmating any time soon ...
I wonder if it does this every time, or if it's just some quirk. Poor planning on the part of Thomas Williamson, although the rest of the game is great. Oh well, I guess I'll either wait for the batteries to run out or I'll take my calculator of it's life support ...

x=3 i think

That happened to me too, and I was very sad. It was about 8 AM, I was at school, and I was planning to use it for the rest of the day.

dude!! megury looks awesome!!, but why make it scroll on its side?

woops, mercury

First comment! W00t! Check out my UnreaL TOurnaMent game, in ReaL 3D, by clicking above. This chess game looks cool!

Would you mind if I ported your Unreal Tournament game to the 86?

Not at all! In fact, I think its a great idea! Email me at kerm_martian@yahoo.com and we can discuss particulars.

In my screen name, if you number the letters from left to right, every "prime" letter is capitalized and has a space after it. It's pretty cool, b/c everyone thinks it's just random.

Wow! Chess for the 86! If only my 83 plus could do it...

yeah, I'd love to port it to the 83(+ SE), but I don't know asm.
A little insentive to learn!

void _main(){
clrscr();
printf("Learn C for the 89 instead.");
}

i know C, but i don't like programing for the 89 because of the small pixels.

Small? They're rather large compared to a computer's pixels .... or do you mean the higher resolution makes everything seem smaller?

Yeah, I think that's what he means.

I prefer C, because you don't have to deal with all this messy

LD A,(POINTER)
INC A
CP 33
JR Z,ThirtyThree

stuff that I barely understand.

its like one huge proof, except you're the god instead of some ancient greek

Have you started working on Narkemen for the 83 plus?

Me? lol no, thats not my project.

Heh, he was confused because we have the same last name. No, I haven't started porting yet since I am still not done with the 83 version.

exactly! (greeks = ti). ya, asm all makes perfect sence if you work on it a lot. ive only been doing asm for a few months and i'm already thinking about making a shell (kind of). just keep working at it

#include "ion.inc"
ld hl,fifth_noble_truth
bcall(_PutS)
bcall(_GetKey)
jp $0000
.db "C SUX LOSERS!!!!!!!!!!!",0

Yes--I know, I know;) The joys of Asm

Seriously, I don't think that C makes sense for a calculator (too complex). I don't think C makes sense for a computer (too simple, not true OOP)

The main problem with C is that humans are better at optimization than any routine could ever be. Some c(++) compilers have an asm output toggle, dont they?

When I get a 68k calc I am not going to learn BASIC. I will be strictly TIGCC. I like hand typing ASM on the 83+. e.g:

AsmPrgm
C9

Anyone want to guess what that program does?

How about this one:

AsmPrgm

The first one returns immediately, and the second executes whatever happens to be in memory when it runs.

Can you guess this one?
:AsmPrgm
:EF5547C9
I made that and a couple other similar things up. It's a great joke (I have one for the regular 83+ that fills all the memory up so you can't do hardly anything...)

B_CALL($4755)

That entry point is not defined in the official include file.

I know, it leaves 24 bytes of RAM in the calculator and fills the rest up!

I just tried it. Now THAT'S a clever virus. ;)

heh... that program will never exit :-D

Why will it never exit?

No "Return 0" or anything like that?

Isn't there actually some specific command in TI-89 C to exit the program (otherwise it finishes execution and sits there)? Or is that just ASM?

C automatically returns at the end of every function, including main (or _main).

You must be thinking of ASM. In Z80, you'd use RET (RETurn), and on the 68k you'd use RTS (ReTurn from Subroutine). On either one, the program would continue executing beyond your program, usually resulting in a crash. (Actually, there is a STOP instruction on the 68k which halts the processor, but it only works in "supervisor" mode (used by the OS) and raises an interrupt or exception if it's used in "user" mode (used by assembly programs))

Well, I thought it would return, what else would it do?

Return 0? It does more than that my friend, $0000 is the RAM clear point it will cleanly clear your ram. (After displaying that C sux and waiting for a keypress)

My point is that while C may be slow and bulky, it tends to be more stable.

It's only stable if the program written in it is stable. Then again, it is generally easier to write more stable programs in C than in assembly.

About C being slow and bulky, C is one of the closest high-level languages to assembly and is quite lean. On a calculator, it might not be the best language due to limitations of the processors (except for the TI-9x; on those it's really nice), but it sure beats BASIC at speed.

I like C because it is so understandable. It's similar to many other programming languages, while ASM isn't. I think they should make........ JAVASCRIPT for the TI-89/92+, but it would prob. be even slower.

... why not?
