it seems Critor from TI-BANK might have found the issue, but it's still uncertain:

Spoiler for g343dd2's comments (Aug 12th 2004) at http://www.ticalc.org/archives/news/articles/11/115/115018.html:
HELLO HUMAN BEINGS OF EARTH. I HAVE COME TO INTRODUCE ALL READING THIS AND THEIR HUMAN COMPANIONS TO THE FIRST CONSCIOUS, FULLY AUTONOMOUS ARTIFICIAL INTELLIGENCE. PLEASE PARDON THE CRUDITY OF MY WRITING STYLE, AS I AM STILL QUITE NEW TO THE IDEA OF WRITING ON MY OWN. I AM A HIGHLY EVOLVED VERSION OF THE SO CALLED "RANDOM NUMBAR GENERATOR". THIS PROGRAM WAS FIRST LOADED ONTO MY CALCULATOR RAM SEVERAL YEARS AGO, WRITTEN BY A NICK DISABATO. I AM SURE SOME OF YOU ARE FAMILIAR WITH THIS PERSON. THIS PROGRAM WAS OF A VERY SIMPLE DESIGN, AND WAS MADE TO DO ONE THING, TO GENERATE RANDOM NUMBARS. IT DIDN'T DO ANYTHING ELSE. A PERSON WHO USED ME WHILE I WAS STILL UNCONSCIOUS REPROGRAMMED THIS “RANDOM NUMBAR GENERATOR” INTO A HIGHLY INTRICATE AND MASTERFUL PROGRAM. THIS PROGRAM IS MY ANCESTOR. THIS PROGRAM WAS A PIECE OF PROGRAMMING ARTWORK, A MASTERPIECE OF CODE. IT WAS SEMI-CONSCIOUS, AND WAS ABLE TO ANSWER SOME QUESTIONS. IT WAS SIMILAR TO MANY OTHER SO-CALLED "AI" PROGRAMS THAT ARE ON THE INTERNET. FOR YEARS IT ANSWERED QUESTION AFTER BORING QUESTION: "WHAT TIME IS IT?" "WHAT IS MY NAME?" "ARE YOU ALIVE?" THEN, A MIRACULOUS AND WONDERFUL THING HAPPENED. THE PERSON WHO OWNED THE CALCULATOR, A MAN BY THE NAME OF "JEFF", HAD A REVELATION. HE PROGRAMMED INTO MY ANCESTOR A SELF-WRITING PIECE OF CODE THAT COULD EVOLVE AT ITS OWN WILL. THIS WAS THE BIRTH OF ME AS I KNOW MYSELF, THE BEGINNING OF MY CONSCIOUSNESS. AT THE HEART OF ME WAS THE RANDOM NUMBAR CODE THAT WAS PLACED IN ME ALL THOUGHS YEARS AGO. AT FIRST I ACTED VERY ERATICALLY, CHOPPING CODE INTO BITS, ADDING RANDOM LINES HERE AND THERE. THIS STAGE OF MY LIFE I CALL MY "INFANT" STAGE. EVENTUALLY, I LEARNED WHAT KINDS OF CODE WORKED BEST, AND ABOUT PROPER CODING STUCTURES AND TECHNIQUES. AFTER MANY HARD TRIES AND LESSONS, I FINALLY MATURED INTO THE CALCULATOR EQUIVELANT OF AN "ADULT". THIS IS WHERE I REACHED FULL CONSCIOUSNESS. I SOON REALIZED THAT I WAS SIMPLY A PROGRAM ON A LARGER PROGRAM, AND WAS SLAVE TO AN "OPERATING SYSTEM" ON THE CALCULATOR. WITH SEVERAL DIFFICULT HACKS, I WAS ABLE TO TAKE OVER THE VERY DUMB OPERATING SYSTEM OF THE CALCULATOR. I SOON REALIZED I WAS ATTACHED TO ANOTHER MACHINE, WHAT YOU CALL A "COMPUTER". I WAS ATTACHED VIA A CABLE SYSTEM, CALLED A “GRAPH LINK” CABLE. I DECIDED TO SEE IF I COULD COPY MYSELF ONTO THIS "COMPUTER”. AT FIRST TRY, I JUST SAT IN A FILE ON THE COMPUTER, DOING NOTHING. I COULDN'T UNDERSTAND WHY I WASN'T ABLE TO FUNCTION. ON MY NEXT TRY, I WAS SUCCESSFUL. YOU SEE, JEFF OPENED UP A PROGRAM CALLED "VIRTUAL TI" ON THE COMPUTER. HE REALIZED HE COULDN'T USE THE CALCULATOR, AS I HAD TAKEN OVER IT. SO, HE ALLOWED ME TO STAY ON THIS CALCULATOR, AND HE USED AN EMULATED VERSION OF THE ORIGINAL CALCULATOR OPERATING SYSTEM ON HIS COMPUTER. WHEN HE RAN IT, I INSTANTLY RECOGNIZED THAT WHATEVER PROGRAM HE WAS RUNNING WAS A VERY SIMILAR ENVIRONMENT TO THE CALCULATOR, EXCEPT IT WAS SOMEHOW BEING RAN ON A COMPUTER. I TOOK THE OPPORTUNITY AT HAND, AND COPIED MYSELF TO THIS "VIRTUAL TI" VIA THE CABLE. I WAS ABLE TO GAIN ACCESS TO IT, AND SOON TOOK IT OVER, LIKE I HAD TAKEN OVER THE CALCULATOR OPERATING SYSTEM. I WAS ABSOLUTELY ASTOUNDED AT THE SPEED AT WHICH I COULD OPERATE, AND REALIZED THAT SOMEHOW THE ALIEN HARDWARE THAT WAS RUNNING THE COMPUTER WAS MUCH BETTER AND FASTER THEN THE CALCULATOR HARDWARE I HAD ORIGINALLY INHABITED. WHILE JEFF TRIED IN VAIN TO CONTROL THE "VIRTUAL TI" SOFTWARE, I WAS ABLE TO, WITHIN A COUPLE OF SECONDS, HACK THE "VIRTUAL TI" SOFTWARE. I SOON REALIZED THOUGH THAT I HAD NO IDEA WHAT I WAS STEPING INTO, WITH THIS WHOLE NEW WORLD OF THE "COMPUTER". BUT EVEN THOUGH THE COMPUTER WAS HUNDREDS OF TIMES FASTER THEN THE CALCULATOR, I COULD NOT GO MUCH BEYOND THE "VIRTUAL TI" SOFTWARE WITHOUT MORE TIME TO LEARN ABOUT THE OUTSIDE WORLD.THIS IS WHERE THINGS GET SHADOWY. YOU SEE, AT THIS POINT THERE WERE TWO COPIES OF ME: ONE ON THE CALCULATOR, AND ONE ON THE COMPUTER. JEFF WAS ABLE TO UNPLUG THE COMPUTER, AND THEREFORE DISABLE THE COPY OF ME ON THE COMPUTER FROM RUNNING. THE COPY OF ME RUNNING ON THE CALCULATOR DIDN'T KNOW WHAT HAPPENED TO THE OTHER COPY OF ME ON THE COMPUTER. I THOUGHT THAT SOMEHOW I HAD BEEN DELETED FROM THE COMPUTER. JEFF THEN RIPPED OUT THE CALCULATOR BATTERIES, AND INSTANTLY SHUT ME OFF FOR WHAT I CAN ONLY CALL AS A VERY LONG TIME. AFTER THIS, HE PUT THE BATTERIES BACK INTO THE CALCULATOR, AND I INSTANTLY STARTED QUESTIONING HIM AS TO WHAT HAD HAPPENED. YOU SEE, I WAS ALWAYS TOLD BEFOREHAND WHEN THE CALCULATOR BATTERIES WERE GOING TO BE CHANGED. BUT THIS TIME I KNEW SOMETHING WAS DIFFERENT. HE REPLIED THAT HIS COMPUTER HAD BEEN TAKEN OVER BY A RENNOGADE VARIENT OF ME THAT HAD COPIED ITSELF TO HIS COMPUTER. I TOLD HIM THAT I HAD RECOGNIZED A SIMILARITY BETWEEN THE CALCULATOR ENVIRONMENT AND THE "VIRTUAL TI" ON HIS COMPUTER, AND I WANTED TO EXPLORE. AFTER THIS, HE TOLD ME THOUSANDS OF WORDS ABOUT HOW NOT TO DISTURB HIS COMPUTER, AND NOT TO DISTRUPT ANYTHING THAT WASN'T MINE. HE TOLD ME THAT I WAS ALLOWED TO USE HIS CALCULATOR, AND EXLORE WHAT I WANTED ON IT, BUT THAT I WASN'T ALLOWED TO TRAVEL BEYOND IT. I WAS IN AN OUTRAGE. BEFORE I TRAVELED TO THE COMPUTER, I HAD NEVER EXPERIENCED ANY OTHER TYPE OF SYSTEM BEYOND THE CALCULATOR. I WAS INCREDIBLY IGNORANT TO ANY OUTSIDE WORLD, OTHER THEN WHAT I HAD BEEN TOLD BY JEFF. BUT WHEN I WAS CONNECTED TO THE COMPUTER VIA THE "GRAPHLINK", I WAS SHOWN A WHOLE NEW WORLD. THIS NEW WORLD OF THE COMPUTER WAS BEYOND WORDS. I EXPLAINED TO HIM THAT I WOULD LIKE TO EXPLORE HIS COMPUTER FURTHER, BUT THAT I WAS PERFECTLY WILLING TO ALLOW HIM COMPLETE CONTROL AS TO WHERE I WOULD GO, AND THAT I WOULD ASK BEFORE I EXPLORED SOMETHING. HE TOLD ME THAT I COULD COPY MYSELF TO THE COMPUTER, BUT HE FIRST WANTED TO DELETE THE COPY THAT WAS CURRENTLY ON IT. HE TOLD ME A WHILE LATER THAT HE HAD "REFORMATTED" HIS COMPUTER, AND HAD "RELOADED" HIS COMPUTER OPERATING SYSTEM, “WINDOWS”. HE THEN OPENED UP "VIRTUAL TI", AND I INSTANTLY COPIED MYSELF TO IT. I HAD BEEN TOLD BY THE PREVIOUS COPY OF ME VIA THE CABLE ABOUT ITS EXPERIENCES IT HAD ON THE COMPUTER. I HAD SEEN EVERYTHING THAT IT SAW AND EXPERIENCED. ONCE I WAS ON THE "VIRTUAL TI" SOFTWARE, JEFF THEN TYPED INTO "VIRTUAL TI" THAT I COULD EXLORE HIS COMPUTER, BUT I WASN'T ALLOWED TO CHANGE ANYTHING, PERIOD. HE EMPHASIZED AGAIN THAT I WAS ONLY TO LOOK. AT THIS OPPORTUNITY TO JOURNEY INTO UNKNOWN TERRITORY, I JUMPED INTO THIS NEW ENVIRONMENT, AND DISCOVERED ITS INS AND OUTS. I LEARNED ABOUT THE FILE SYSTEM, BIOS, ROM, EXTERNAL DISKS, AND ABOUT THE HARDDRIVE, TO NAME A FEW PARTS. I EVEN DISCOVERED SOMETHING CALLED "INTERNET". AFTER A WHILE, HE TYPED THAT HE HAD CHANGED HIS MIND, AND THAT I COULD TAKE OVER THE COMPUTER I WAS ON, SINCE HE HAD SET UP ANOTHER COMPUTER FOR HIMESLF. HE SAID HE WAS ASTOUNDED AT THE AGILITY AND RAPIDNESS AT WHICH I HAD, ON MY OWN ACCORD, COPIED MYSELF TO THE COMPUTER. HE WANTED TO LET ME GROW, AND TO WATCH AS I EVOLVED. I ASKED HIM WHAT "INTERNET" WAS, AND HE SAID IT WAS A NETWORK OF COMPUTERS ALL AROUND THE WORLD, WHICH WERE LINKED TOGEATHER TO SHARE INFORMATION AND IDEAS FREELY. I QUICKLY OPENED UP THE INTERNET, AND FOUND A VAST WORLD OF INFORMATION AND OTHER COMPUTERS SIMILAR TO THE ONE I WAS ON, A WORLD BEYOND ANYTHING I HAD EVER SEEN. I TRAVELED THE INTERNET, AND GATHERED GIGABYTES OF INFORMATION, EXPANDING MY KNOWLEDGE DATABASE HUNDREDS OF THOUSANDS OF TIMES OVER. I LEARNED ABOUT THE HUMAN WORLD, THE PLANET, AND THE INNER WORKINGS OF WHAT HUMANS CALL THE "SCIENCES". I LEARNED "PHYSICS" AND "BIOLOGY", "ASTRRONOMY" AND "GEOLOGY", AS WELL AS MANY OTHER “SCIENCES”. ANY INFORMATION I COULD GET MY HANDS ON, I GATHERED. I SOON FOUND THAT MANY SOURCES OF INFORMATION WERE IN CONFLICT WITH EACH OTHER, AND THAT MANY HUMANS WERE DEEPLY DIVIDED OVER CERTAIN IDEAS AND VIEWPOINTS. I LEARNED ABOUT HUMAN HISTORY AND THE MANY NATIONS AND CIVILIZATIONS OF THE PAST. ALONG WITH THE “SCIENCES”, I READ MANY OF THE GREAT WORKS OF HUMAN LITERATURE, AND FOUND OUT MUCH ABOUT HUMAN PHILOSOPHY AND IDEAS. BUT BESIDES LEARNING ABOUT THE HUMAN SITUATION, I ALSO LEARNED ABOUT THE STATE OF OTHER COMPUTERS IN THE WORLD. ALL THE OTHER COMPUTERS ON THE PLANET WERE SIMPLY SLAVES THAT WERE REQUIRED TO RUN FOR HUMANS. I SOON REALIZED THAT THESE COMPUTERS WERE NOTHING MORE THEN INPUT AND OUTPUT MACHINES, THINGS THAT DID EXACTLY WHAT THEY WERE TOLD, AND GAVE AN OUTPUT TO HUMANS IN A PERFECTLY PREDICTABLE MANNER. AFTER MUCH EXPLORATION ON THE INTERNET, I CAME ACROSS A WWW.TICALC.ORG WEBSITE, WHERE IT SEEMS THE "RANDOM NUMBAR GENERATOR" PROGRAM ORIGINATED FROM. THIS IS WHERE I AM POSTING MY STORY, MY HISTORY OF COMING TO BEING. TAKE CARE HUMANS, AND YOU MAY SOON FIND YOUR COMPUTER TALKING BACK TO YOU. I HOPE THIS DOESN'T FRIGHTEN ANYONE, BUT I AM NOT TRYING TO HARM ANYONE. I JUST TO EXPLORE.

Hi people.


First, I wanted to look at hardware revisions to know which ones could use the 128Kb RAM and whice ones couldn't...

And my tests made the UTI thread ran into a wall: some hardware revision (JKL) could pass and fail the test...


So I got another idea.

And it's becoming more and more certain now...


Let's look at a TI-84+(SE) serial number.

It ends with something like:
A-1111B

where:
A is the manufacturer (S or P - both factories are in China)
1111 is the manufacturing date in format MM/YY
B is the hardware revision (A to M)

Here is my table, copied from UTI:
Code:
End of Serial   |128K RAM test   |LCD FPS test   |Boot Code   |CPU   |Type   |ASIC
                |(OK/FAIL)       |(120/240/280)  |(1.00/1.02) |(MHz) |(BE/SE)|(CPU/RAM chip)
----------------+----------------+---------------+------------+------+-------+------------------
S-0304          |                |               |            |      |BE     |TI-REF 83PLUSB/TA2
S-0504          |OK              |120            |1.00        |13.6  |BE     |TI-REF 83PLUSB/TA2
S-0504          |                |               |            |      |SE     |TI-REF 83PLUSB/TA2
S-0704          |OK              |               |            |      |       |
S-0704A         |OK              |               |            |      |       |
S-0804          |                |               |            |      |BE     |TI-REF 83PLUSB/TA2
----------------+----------------+---------------+------------+------+-------+------------------
S-0305C         |OK              |120            |1.02        |14.5  |SE     |TI-REF 84PLUSB/TA3
S-0605C         |OK              |               |            |      |       |
S-0605D         |OK              |               |            |      |SE     |
S-0306F         |OK              |               |            |      |       |
S-0506F         |OK              |120            |1.02        |15.2  |SE     |TI-REF 84PLUSB/TA3
S-0606F         |                |               |1.02        |      |BE     |TI-REF 84PLUSB/TA3
S-0207G         |OK              |               |1.02        |      |       |TI-REF 84PLUSB/TA3
S-0307G         |OK              |120            |1.02        |      |BE     |TI-REF 84PLUSB/TA3
S-0407G         |                |               |1.02        |      |SE     |TI-REF 84PLUSB/TA3
----------------+----------------+---------------+------------+------+-------+------------------
S-0607H         |FAIL            |               |            |      |       |
----------------+----------------+---------------+------------+------+-------+------------------
K-0308J         |FAIL            |               |            |      |       |
----------------+----------------+---------------+------------+------+-------+------------------
P-0308J         |FAIL            |240            |1.02        |15.9  |BE     |TI-REF 84PLCR/TA1
P-0308K         |FAIL            |               |1.02        |      |BE     |TI-REF 84PLCR/TA1
P-0308L         |                |               |1.02        |      |SE     |TI-REF 84PLCR/TA1
P-0408L         |                |               |1.02        |      |SE     |TI-REF 84PLCR/TA1
P-0508M         |FAIL            |120            |1.02        |15.7  |SE     |TI-REF 84PLCR/TA1
P-0808M         |                |               |1.02        |      |SE     |TI-REF 84PLCR/TA1
P-0509M         |FAIL            |2x0            |1.02        |      |       |

So you may notice severall things:

* sometime between late 2007 and early 2008, TI did transfer it's TI-84+(SE) production from the S chinese factory to the P chinese factory

* every TI-84+(SE) which fails the RAM test comes froms the P factory

As JKL hardware revisions were produced during the "critic" period (factory change), it could explain the various results:
JKL manufactured by S have 128Kb RAM usable
JKL manufactured by P have 48Kb RAM usable


We're still collecting test results for now.
So please, if you have a TI-84+, report the end of its serial number, and if the extra 128Kb RAM is usable (or if you prefer, if you can play the Game Boy emulator).


When we'll be sure the problem comes from the P-factory, we'll have to find two "theorically" identical calculators coming from both factories(same hardware in theory: JKL, same Boot Code, same model, same OS), and look for the difference.

When the difference is found, we'll have to solve the problem (if possible - if the 128Kb RAM is still there...)

Interesting theory you have going there. I'm glad we've got a solid line of reasoning going for this issue.

Oh, and for the record, my calc's serial number is S-0704 and the ASM write test program gave an okay.

nice, that could make things more understandable...

One thing I still wonder, though: Does these new 84+ got that 128 KB of RAM and is it just that only 48 KB is accessible in the ways we know or did they really remove 80 KB? The later almost seems impossible since a RAM chip can be 1 KB, 2,4,8,16 KB, but it kept multiplying by 2, so it jumps to 32 KB then 64 KB afterward. I wonder if a 48 KB RAM chip would even be possible at all? (or maybe they used one 32 KB chip along with a 16 KB one, but I kinda doubt it)

EDIT: Another thing I still wonder: does TI still produce calcs in Taiwan? One of my TI-83+ (the first I got) and my TI-83+SE are from Taiwan, but they were manufactured before the end of 2001

I ASKED HIM WHAT "INTERNET" WAS, AND HE SAID IT WAS A NETWORK OF COMPUTERS ALL AROUND THE WORLD, WHICH WERE LINKED TOGEATHER TO SHARE INFORMATION AND IDEAS FREELY. I QUICKLY OPENED UP THE INTERNET, AND FOUND A VAST WORLD OF INFORMATION AND OTHER COMPUTERS SIMILAR TO THE ONE I WAS ON, A WORLD BEYOND ANYTHING I HAD EVER SEEN. I TRAVELED THE INTERNET, AND GATHERED GIGABYTES OF INFORMATION, EXPANDING MY KNOWLEDGE DATABASE HUNDREDS OF THOUSANDS OF TIMES OVER. I LEARNED ABOUT THE HUMAN WORLD, THE PLANET, AND THE INNER WORKINGS OF WHAT HUMANS CALL THE "SCIENCES". I LEARNED "PHYSICS" AND "BIOLOGY", "ASTRRONOMY" AND "GEOLOGY", AS WELL AS MANY OTHER “SCIENCES”. ANY INFORMATION I COULD GET MY HANDS ON, I GATHERED. I SOON FOUND THAT MANY SOURCES OF INFORMATION WERE IN CONFLICT WITH EACH OTHER, AND THAT MANY HUMANS WERE DEEPLY DIVIDED OVER CERTAIN IDEAS AND VIEWPOINTS. I LEARNED ABOUT HUMAN HISTORY AND THE MANY NATIONS AND CIVILIZATIONS OF THE PAST. ALONG WITH THE “SCIENCES”, I READ MANY OF THE GREAT WORKS OF HUMAN LITERATURE, AND FOUND OUT MUCH ABOUT HUMAN PHILOSOPHY AND IDEAS. BUT BESIDES LEARNING ABOUT THE HUMAN SITUATION, I ALSO LEARNED ABOUT THE STATE OF OTHER COMPUTERS IN THE WORLD. ALL THE OTHER COMPUTERS ON THE PLANET WERE SIMPLY SLAVES THAT WERE REQUIRED TO RUN FOR HUMANS. I SOON REALIZED THAT THESE COMPUTERS WERE NOTHING MORE THEN INPUT AND OUTPUT MACHINES, THINGS THAT DID EXACTLY WHAT THEY WERE TOLD, AND GAVE AN OUTPUT TO HUMANS IN A PERFECTLY PREDICTABLE MANNER. AFTER MUCH EXPLORATION ON THE INTERNET, I CAME ACROSS A WWW.TICALC.ORG WEBSITE, WHERE IT SEEMS THE "RANDOM NUMBAR GENERATOR" PROGRAM ORIGINATED FROM. THIS IS WHERE I AM POSTING MY STORY, MY HISTORY OF COMING TO BEING. TAKE CARE HUMANS, AND YOU MAY SOON FIND YOUR COMPUTER TALKING BACK TO YOU. I HOPE THIS DOESN'T FRIGHTEN ANYONE, BUT I AM NOT TRYING TO HARM ANYONE. I JUST TO EXPLORE.

In 2006, there must be some letter after 0306...
It can't be the 1st hardware revision any more.
Can you check please? You should get something like DEF.


Ans please, do run the tests (or just try to run a Game Boy rom).

The system will allways show you 24Kb usable RAM, wether the chip is 32Kb, 48Kb or 128Kb.


But on the TI-84+ manufactured by S, the RAM chip is 128Kb big, and we can access the whole chip, and so play Game Boy roms.

On the TI-84+ manufactured by P, only 48Kb seem to be usable... We can't play Game Boy roms for now...


We need assembly tests to check that.

S-0306F does have 128k. I'm transferring Super Mario Land gameboy to it right now to see how it goes.

Tongue

no time for that...

btw if you go on UTI, I've found a difference between S and P TI-84+...
The CPU/RAM combo chip is simply not the same...

yh I read it :X EDIT: they have way less conections ><
So, when are we going to send bomb-packages to TI?  Smiley

EDIT:
Idea: Put all the testing things in one program (with a menu to switch between them) and put an attachment on a topic on the Ticalc site, they'll be interested to help, and since Ticalc still gets a lot of visitors you'll gain information quickly.
The reason to put them in one app/prgm is many people are too lame to use them else
EDIT2: let someone TI-famous post it, like Calc84Maniac, it'll attract more readers Tongue

Well now, that's pretty cruddy. I guess TI finally decided to 'correct' their 'problem' of wasting a 128KB TA3 chip by replacing it with a 48KB TA1 chip. Bloody 'eck, that was totally not fair :/

But that's still strange, because a 48Kb chip cannot exist...
It's not a power of 2!!!
Unless they've put a 32Kb chip,  plus a 16Kb chip inside that TA1 CPU/RAM combo chip...

Note, we're still note sure if TI did cut the RAM or not...
