Scott Noveck Addresses Concerns With TI-89 Hardware v2.00
Posted by Nick on 18 November 1999, 03:15 GMT

Scott Noveck of Assembly Coder's Zenith (ACZ) wrote an interesting bit of information on his home page yesterday concerning exactly why Hardware Version 2.00 has problems with grayscale.

The text of the news item is as follows:

"Also, I've finally managed to get some important information from TI on the hardware and software differences between the original 89s and the 'new' ones (if you go to file -> about from the home screen and see 'Hardware Version 2.00,' then you have a new model - these have problems running several programs). In addition to the usual quirks found in ROM v1.05 that requires programs to be patched, some hardware modifications have been made that prevent greyscale from running the conventional way. I should be able to fix this, although any greyscale routines will need to be modified directly through the source - not just patched. Also, these are running the exact same processors that the old ones used - same speed and all. There were some modifications to the way the LCD screen refreshes, which does speed up complex math a lot on new models. More information coming soon =)"

We hope this sheds some more light on the issue, and why it's so hard to upgrade some programs. Also, in the long run, this will help out with doing math on the calculator (which was its original intention *g*) which is a big plus in my opinion.

I think I'm correct in saying that most TI-89/92+ games use either graphlib or gray4lib for gray-scale, so most gray-scale programs could probably be made compatible with the new hardware version just by changing these libraries slightly. The programs which use the libraries wouldn't need any changes.

I understand that Scott said that the hardware version 2.00 was the SAME processor as HW 2.00, speed and all, but how come E-V-E-R-Y-B-O-D-Y keeps saying that the processor speed is 12mhz, 2mhz faster than hardware v 1.00??? I don't get this. Where did those people get 12mhz from anyway??? Also, I heard some people say that 2.00 is superior to 1.00. Is that true?

Possibly a rumor someone started because the new 89s do large math problems faster? They will be faster at math, definately, but that's due to some LCD changes that speed up memory access

No this is not a rumor. Paul King, an employee from TI clearly stated in a post on the TI-89/92+ Message Board on TI's site stating that the processor was running at 12MHz. Maybe he meant that it was running to something compareable to 12MHz?

It says in a comparison c6hart on ti's website that the calc uses a motorola 68k 12mhz processor. However, it only runs at 10 mhz. I don't know if this is different on the new hardware, but I presume it is possible.

It is also possible that the system bus speed only runs at ~10MHz on the old89 and runs at ~12Mhz on the HW2... This would not only show speed increases while processing complex math problems, but also increase ROM call speeds and RAM data transfers.

I am not saying THIS IS HOW IT IS, I am merely stating that it could be this way. I assume this because I was told that the old89 and the HW2 have the same Motorola68000 chip. As stated by someone else, the MHz of the chip can be altered with relation to the heat given off by the processor, although the MIPS cannot change.

This would probably seem to be the best answer so far. I have noticed tha (Un)Archiving and (Un)Zipping variables is **ALOT** faster with HW 2.00, this could be due to your explanation.

Maybe Texas overclockes the processor ? I mean they use same, but 2Mhz more is not impossible by changing condensator

2.00 , overclocking the ti-89

The new version won't work with some of the games for some reason, I don't know why. It is only on the v2.00 though, I had to downgrade my calc version to 1.00 from another calculator to do this....why?!?!

Hey, does anyone know how to overclock the 89?

One Problem That Still Annoys Me. I Attempted A Transfer Or The 1.00 Rom To THE New 89's and it sent a 1.06 That has ruined my friends 89. How It Came Up With 1.06 I Do Not Know But They (TI) Seem To Be Baffled By The Occurance Themslves. If Anyone Has Any Idea IF POSSIBLE to get the 1.00 rom to run on the Hardware v2.00 89 Please email me or reply.

Also Here is a small list of the games that Actually Do work on the new 89.

Breakout v0.1
Falldown v2.3
FInvaders v1.0
Frogger v1.0
Jezzball v1.7
Nibble v1.1
Phoenix
SMQ (Super Mario Quest) (*** DO NOT ARCHIVE ***)
Solar (Solar Striker)
Spong (Super Pong)
TicTacTo
TND (The Next Dimension)
Tunnel (Tunnel Not Tunnl)

This Is Just A Small List

And The Sonic Misadventures Does Not (WOuld Like To Play It...)

Also Will Someone Send Me Or Post The Link To A 1.00 Flash Rom?

All Help Is Appreciated,

DarkMagus,

Oh Yeah, And These Are Ran With Plusshell 1.00

P.S. Why Would You Overclock an 89???

that same problem happened to me when i tried to downgrade, it displayed 1.06.....i have no clue what it means, but i had to clear my memory :-(

Only Problem Is My Friends Accepted It!!!!
Now Its Screwed Forever.

P.S.
This Is What Happens When You Overclock Your 89

WALLA WALLA, WA - On Wednesday, a seventh grader attending Lincoln Middle School accidentally overclocked his TI-89 "a bit too much," sources say.

The student, named Bryant Kramss, replaced the C9 capacitor with one made of pure radium for reasons unknown. According to family members, Bryant "felt he had an innate need to make his TI-89 three kilohertz faster" by replacing it with the insanely unstable element.
As noticeable in the picture, taken in supposedly total darkness, the 89 has obtained a pale greenish glow. Rumors that the modified 89 does 100! in under a picosecond are unconfirmed.
Bryant was admitted to Holy Family Hospital in Walla Walla on Thursday morning after he happened to notice the growth of a small tumor and an extra arm. He was then given prompt chemotherapy and he is now in serious condition. He is expected to fully recover very soon, as the dosage of radiation was not severe enough to cause any permanent damage.
The 89 is currently under the FBI's custody, which is having tests run on it. The source of the radium is still unknown.

If you hold the APPS button as you insert the batteries, it should force the calc into a mode where it can accept the flash download from a computer.

This problem occurs because for some unprobable reason, your HW2 calc accepted the AMS 1.00 ROM transfer, when it shouldn't have. Because of the hardware differences in HW2, you _cannot_ install AMS 1.00 on it. AMS 1.00 does not contain the correct keyboard array (and other vital info) that has changed with the hardware version.

You must use AMS 1.05 or greater.

I have hardware version 1.00 and upgraded about a week ago to AMS v 1.05. Is there anyway to downgrade to AMS v 1.00? can you tell me how or give me the link?

I had the same problem. All I did was E-mail TI. In the e-mail I included my product ID and my Serial # (Both can be found on the About screen). It took a few days, but they finally sent it to me.

Well.. I tried to downgrade a TI-89 with HW2 and AMS1.5 to 1.00 using the calc-to-calc instead of a computer, and the other TI-89 gave me an error like,
"Checksum Error", and thats as far as it went. It also said 1.06. But I can still reset the calc and everything runs fine. I didn't know what the checksum error meant though... any ideas?

RE: checksum error when trying to install AMS 1.00
Andrew Timson

All the checksum error means is that the AMS version 1.00 is incompatible with your calculator; TI included this to prevent people from using incompatible versions of the AMS with Hardware v2.00. As long you are running 1.05 or later on your calculator, you can ignore the error.
