Creating Os Help

Hey dudes out there who know more about ASM then me, how do you create an OS for the TI-83+?? Oh come on, help me!

You don't. Violation of copy right laws. Michael Vincent tried it once, but he had to stop because TI told him to. (Or however that went. Someone go ahead and correct me if I'm wrong.)

He might mean an OS like Mirage or ION. I'm not an ASM programmer, but if you already know ASM, then figure out how to get the information for the programs on the calc (like what language they are in, size, etc.). Then figure out how to do things like hide and lock them, display remaining battery power, change the contrast, etc. There are ways to do all of these. Remember there are already a whole bunch of good OS's out and coming out, so if you are really going to try this, be prepared to dedicate a lot of time and effort.

btw if you are doing this in BASIC, don't even try. Since you can't do prgmStr4, you can't run a program specified by the user. It's just not possible with BASIC.

It is legal to create anything you want.

It is legal to post anything you create provided you did not steal code when you created it.

It is leagal to copy fuctionality provided you do not us copyrighted logos et cetera and you do not steal code.

It is leagal to provide information about installing stuff, getting around security problems, et cetera.

Essentially, Michael Vincent can release his OS.

Wasn't the problem about being able to download apps without validation if you have your own OS that doesn't validate?

Um I thought it was something about how he had to "borrow" a few sections of code from TI's OS, which was the copyrighted stuff he got in trouble for.

I think if it were possible to write the entire thing from scratch, you'd be fine.

O.K. Maybe I did not clearly state what I was saying. What I kind of OS I meant was like Mirage and Ion. However, how do you also add some new commands in an OS like how Mirage added new ones? Oh yeah, how do you also check batts. etc.?

Jedd · Posted: 07 Jan 2004 08:36:52 pm Post subject:

Just wondering....do you already know ASM?

Look at the forum for NimbusOS and some other places to find information about checking the battery. As for new features, I assume you would just post a new version of the OS on TICalc.org or something.

Hey I don't know a lot about ASM so that's why I posted this topic up. However, I have attempted to look at the other OS topics, but aren't able to understand what are they saying.

Then you should probably do some simpler stuff before you dive into making an OS. Make some simple games in ASM. Once you feel comfortable with the programming, go ahead and try making you own OS.

Jeremiah Walgren · Posted: 07 Jan 2004 11:35:16 pm Post subject:

Or even a few simple programs just to get the hang of things - then head on to games.

O.K. I got it. However, before I do so, I still don't get what it means by flash pages in apps header. Oh yeah, anyone out there, who really knows how to create an os that's like ion, etc.??

Jedd · Posted: 08 Jan 2004 02:01:25 am Post subject:

Talk to JBirk and Darth Android. They are both making OS's.

Arcane Wizard · Posted: 08 Jan 2004 09:27:08 am Post subject:

And John and Justin, JBirk isn't making Nimbus alone you know (or wasn't anyway).

I remember AdmWiggin started working on an asm os, maybe you can also get some pointers from him.

hey hey hey! wazzup guys! i worked on WALLSxp for the frist time in MONTHS yesterday! (ASM for the first time in months for that matter)

DO NOT, i repeat, DO NOT try to make an os without at LEAST Intermediate skill in ASM... when i started WALLSxp i wasnt ready, so it was too much. Now, i have learned a language, and a little bit of another, and it is coming much easier even!

but, if you are really set on making an OS, talk to someone who really knows what they are doing Laughing

. i know you must use Jumptables, etc. to make your own routines, but that is about all i know (so far Wink

)

O.K. thanks. Oh yeah, since Adam recommends for me to be an intermediate at least, then I'll need help knowing what the heck an intermediate ASM programmer is supposed to know. Oh yeah, is there also a way to access an app in the calc in an OS?????

shadowing · Posted: 09 Jan 2004 07:07:15 pm Post subject:

Anyone there?? Oh great, I'm talking to myself.

Adm.Wiggin · Posted: 09 Jan 2004 08:36:40 pm Post subject:

oh gosh

do i have to repeat myself everytime someone new comes to the board?

ok, once for old times sakes (i should put this in my sig or something) :
my name is not Adam. Adm. is a miliatary prefix for cryin' out loud. ok class, can anyone tell me what it stands for? Wacko

about being intermediate, you will know when you are ready, so just read tuts. like crazy... check out the "ASM for N00bs" thread (forgot the exact name) maybe it was "N00bs come here for ASM"?
