i need to learn machine code(hex) spucificly for the 83+ if anyone can help email me at ibhook4ever@hotmail.com
so far i can fool around with the registers and memory

i can also convert he, binary, and decilmal to each other freely

Why machine code? It's useless!! However, it can easily be done, just write or load an ASM or BASIC program, and use a hex editor to find it in the system VAT (use a program like CalcSys for the 83+) and thats your program in hexadecimal! You know when to stop when you've viewed every byte of the program size. So for instance if the program is 700 bytes in size, the 700 bytes starting at where the program lies in the VAT is the hexadecimal equivalent. From there you can easily convert to binary. The question is why bother? ASM, although a low-level language, converts directly to machine code through op-codes, so there's no need to learn machine code.

Hope this helps.

how many pixels wide and tall is the 83+ lcd?

Would it be possible to make a camera for the 83+ or a printer

And also, is it possible to hook two 83+ together to expand the memory permanently

96*64 I think, but you can only access 94*62 in basic.

#2:Yes. It's complicated, but it certainly can be done. The hard part is making the calculator understand the data coming in, which requires an interpretation program.

#3:Yes, although it would be hard to view files and the memory would only be accessible when the driver program to link the calculators was running.

I have a ti-83+ se and was wondering if there was anyway to install the ti-86 or 89 operating system on my 83. Thanks

Short answer: no.

Long answer: yes, but you'd have to be a hacker (and it would be pointless). Each calculator has very different hardware than the others. The TI-89 especially is vastly different from the TI-83+, because it has a Motorola 68000 processor and the 83+ has a Zilog Z80 processor.

It would be like putting MS Windows on your Macintosh (who would put MS Windows on *anything* anyway? :-).

Crapintosh user.

Macintosh just sounds retarded...

does any know a program that will convert program meant for other calculator to work on Voyage 200? i have a voyage 200 and i want to use some application meant for ti 83 calculator. DOes anyone know a way or a program to convert the files?

You would need to know Z80 ASM and Sierra C and manually port it.

Because I like to help people learn programming and stuff, I have setup a few yahoo groups where people can learn from me/eachother, share files/programs, post messages, etc. - Trust me, I am among the best, so I think it would be very beneficial.

I am very willing to teach people everything I know whenever I have free time (I like to work on a one-to-one basis). Check out my groups if you are at all interested or curious.

Below are the web addresses for my groups (CAREFUL, I had to put a space after each slash, so if you copy and paste, delete the spaces):

http:// groups.yahoo.com/ group/ TICALC101 - deals with ticalcs and stuff

Could someone come up with a routine to turn on or off the voltage to the wires on the link cable. I've tried:

ld a,%11000000 ;turns on red and white wires
out (7),a

but when I hooked it up to a multimeter, nothing happened. Also, what is the uninsulated wire in the cable? Is it the ground?

im not sure, but that should work if ur using a 86, but if ur using anything else it may be a diferent port

=)

The uninsulated wire is the ground. The voltage probably should be measured between ground and one of the other wires (red or white), else you'll get no voltage if you measure between red and white and turn both of them on (that is, the voltage difference is zero).

Does anyone know about a program convertor or somehting that will enable programs meant for other calculators other than the Voyage 200. I would like to use some application that are built for TI 83 but cant not beecause i have a voyage 200. so if anyone know a way or a program that will convert ti 83 files to work on voyage 200?
thanks

Is there a way to change the format of numbers printed by the 89 (or 86)? Specifically, I want to insert commas to enhance readability.
i.e. 100000.00 would be printed as 100,000.00
Any ideas?

BASIC:

format(100000,"g3")

I have a TI-83 Plus and would like to know how to format numbers so that they have a "Thousand Separator" as well, i.e., 1,526, 25,698, 105,475, etc. I don't understand the "BASIC" term above - is that language, a key or what? Thanks for you help.

BASIC is a high level programming language that is generally unstructured and procedural. The TI calculators uses a BASIC-like language when you put in commands either in a program or the home-screen. Short programs can even be typed directly onto the home screen.
The calculator uses functions to recieve commands. When you type 'sin(30)' into the prompt, the function sin() is called and the number 30 is passed to it. This function ten runs a small piece of code that tells it to return the correct number. Functions are not confined to numbers as they can also operate on text. The TI89 'format' function will take a number and a string as input and return an output that is printed to the screen. The TI83 does not have this function, so to do this you need to write your own function. The functions built into the calculator are described in the manual.

you could install Omnicalc. it has a general settings menu which is very useful is you want to get read of stuff that is unhelpful or useless.
Go to www.detachedsolutions.com for Omniclac, and you can get their other useful Apps. (or you can get Omnicalc at ticalc if you want)
