TI-83 Plus SDK Released
Posted by Nathan on 30 October 1999, 07:17 GMT

Texas Instruments released the TI-83 Plus Software Development Kit. According to the FAQ, this allows software developers to program in Zilog Z80 assembly code. Listing technical specifications and user interface guidelines--as well as offering a "software simulator/debugger"--the SDK will allow programmers to create tight programs that are optimized and integrated with the TI-OS (presently, programmers have used incomplete, hacked TI-83 and TI-83 Plus information for programming). Available only in English, this free SDK will soon be followed by both educational and professional versions, which will allow programmers to write Flash applications which execute directly from the Flash ROM.

I am glad to see ti release more info but couldn't viruses be written that would write to the flashrom > 10,000 times relatively quickly. This would destroy your flash rom.

That whole 10,000 times thing is a rummor/hoax. I asked a TI employee and they said it was a lie and didn't know where it started.

So what your telling me is that I can write to the flashrom all I want and not hurt it.

Right, you can write to the FlashROM as many times as you want and it would matter.

Actually, there is a limit -- but it's around 10,000 times per each individual bit. If you were to fill the archive and garbage collect five times per day, with every single bit being rewritten to, it would take some 7 years to render it totally useless. It's nothing that anyone should worry about, although there IS a limit

Yes, but the point is: I doesn't matter. I doubt that any human could accomplish this task if they wanted to.

Too bad about the limit. TI only spent 5 cents on the calculators flash chips. There are ones around $50 that take a lot longer to where out just like a hard drive. Though if you keep the conditioned they would last for ever. It does not matter anyway by the time my flash wears out I will have a new calculator that probly is not even out yet.

Actually My point was that a program could be written to destroy the Flash Rom. A virus could be made to simulate the calculator shutting off but (but in reallity the screen would only be off) The calculator would be running a virus that continuosly writes and rewrites to the flash rom. It would take a virus some time the reach the 10000 limit but it could be a matter of hours/days not years.

I only have half my acrhive full, but when I use Ion i keep my programs archived in case of a crash. I have to garbage collect about 3 times a day. Is that real bad for my calculator.

Mine is about 1 time a day. and most of my flash is full(because of apps). I know this is bad, luckly I know how to sodder a new 5 cent flash chip to my circuit board. ooo 5 cents very cheap. I don't play games on my calculator all the time so my calcuator will last. I wouldn't be supprised if some of my friends calculators wear out faster than mine. Also I have a new way of fixing the problem but it would require ION to be reprogramed and everyones games that save the highscore to the program. They could make it so it works like a flash app only reading from the flash and writing highscores to the ram to another file. Too bad its unlikely. It's up to Joe Wingbermuehle and all the porters and programers of the games for the 83+.

For some reason, the debugger refuses to send ION to the emulator!

This is because of the conflict between ION and APPS. Maby Joe Wingbermuehle will fix this. Or maby you need to load a newer operating system to the emulator. I'm not sure. Oh well Mac's rule.

All mac users should subscribe to Mac Addict magazine. It comes with free software on a CD for both 68k and PPC based macs.

Your mac uses the same processor as the 89, 92+, what does that say about it? :)

NO it does not. The processers in the mac have more commands. If this were true that means the mac still rules. It's not the processer that sucks its the calculator. The mac's processer is also made in part by IBM, not just motarola. Sorry IBM about the comment above.

P.S. Flame me by mail not by comment.

The Emulator is using version 1.12, but what conflict is there between Ion and Apps?

At least on my calculator and some others if I run an app other than finance (really not an app) it messes up ION. Certain programs don't work right after this and my calculator is at high risk of crashing. The only way of fixing this is reseting my ram, ungrouping all my levels (z stuff or lazerlev) and reinstalling ION. This really dissipointed me because I bought to of ti's apps and I have to do this everytime I use one.

The only trouble I've seen w/ ION & apps is ION 1.0 refuses to run with the calc in a foreign language mode. It hasn't seemed to happen since ION 1.1 came out.

Damm Ti sucks with their prices. They are going to charge $99 for the educatonal and $299 for the professional. What the fuck is their problem. TI is just tring to cheat the developers. TI should actually pay us to make apps and programs for their calculators. I hope someone makes a hack for apps and gives it out for free. That will lower TI's prices and would be sweet pay back. I was expecting the professional verson to be around $99 and the educational to be around at most $50. TI really has done it now. They deserve to be flamed like crap. All the flames that have and are going around should all be sent to TI about these prices. If no one finds a hack I will!!

P.S. Of course I know this comment will be deleted. in at most an hour. I hope someone who feels the same reads it before than. Hopefully Programers will figure out a way.

Maby microsoft can steel TI's development system and make it cheeper and better, they have a reputation for this. I hope someone who works for microsoft reads this. hey they are already tring to steel the videogame busness from nintendo, sony, and saga with there system, code name X-BOX.

I'd help you. Didn't you hear? Ticalc isn't deleting news posts for a while. read the anarchy trial thing.

Gahhh? $299!!!!???? Nooooo! I will happily hack their wares and post them on various mirrors for everyone to download. Ha ha ha ha ha ha ha ha ha. BTW, where did you find this out, is on TI's webpage? Anyways I will hack their wares if cost that much.

Yep on their website, they just released the App SDK well not yet for download but you can get it now for that fricken high price. Microsoft Visual C++ Pro edition is cheaper that that and it has a lot more features for development. eg. visual instead of typing .db "Welcome",0. TI is just ripping developers off. It's because of us developers that there calculators are alot of the time prefered. TI's email address should now be changed from ti-cares@ti.com to ti-cheats@ti.com same with there phone number.
1-800-ti-hates. Hey, maby I will get the people of mad to make fun of them. Ha Ha.

Hey, the ti-82, 85,86,81,80,and the 70 something were hacked, the 83 plus will be some day. Then TI will have to give there developement kit for a cheaper price.

P.S. If someone from texas instruments is reading this, go cheapen the price before you loose customers. Hey, we buy your $100 calculators and $7 to $17 apps and $10 accessorys, we should get some software for free made buy you other than updates and stupid CBL/CBR apps that we will never use since we don't want to pay some other 100 dollars. I bet it only cost you $200 to develop this. You are just greedy with your calculators. Your software cost as much as a playstation 2 or nintendo dolphin, when they come out. What are you going to do next make us pay to enter your site. I bet you will only sell 2000 copys of the thing 97% rich,2% companys.

normally a would but its been so long who was the one who started the mac-pc wars. Try not insulting and you may get some good words from me. Hey, I actually helped someone get started with their calculator when they could not understand why SOS would not work on their 83+. Maby I can be helpful if you ask intellegent questions.

For once I'll actually take that as a complement since I am tired of fighting about platforms for tonight.

Too bad nobody responded to my comment who has a ti 83 plus or at leasts programs for it. Can anyone who knows z80 programing for the 83 plus tell me how you learned it, unless you learned it by looking at others souce code. TI's thing does not give an example on displaying text. Or on making pixels turn on or off.

P.S. The price is only for apps, not for regular programs.

P.S.S. TI will charge more for the 89 and 92(+) versons of the App SDK than the 83 plus.
