If anyone has any calculator from Kinpo (manufacturer code K or L in the serial number, or any with a serial number starting with a letter), please run these tests as well and posf your date code (or if there's no apparent datecode, the first 4 characters of your serial number) along with your results. Kinpo's hardware changes are poorly documented.

You can use LCDTEST4 and LCDTEST5 to check which LCD driver is present in your calculators without popping the cases open. The result of each program is put in Ans, and they can even be run from TI-BASIC programs. My code's pretty unoptimized and has a lot of debug code as I've got other things to do, but LCDTEST4 and LCDTEST5 both work.

Sometime during Inventec Shanghai revision K, the LCD driver changed from Toshiba T6K04 to Novatek NT7564H. This appears to have happened around the start of 2007, and it'd be nice to identify when exactly this occurred as the hardware revision wasn't changed.

These aren't a substitute for opening the calculators and photographing them as we also want to collect info about the PCB labels and the component brands/models, but it's better than nothing and not very difficult to do.

Expected results:
LCDTEST4=1, LCDTEST5=15: T6A04A (or T6A04, but that is only seen in prototypes)
LCDTEST4=1, LCDTEST5=16: T6K04
LCDTEST4=1, LCDTEST5=12: NT7564H
LCDTEST4=0, LCDTEST5=12: New Kinpo LCD driver

I decide to check Cemetech for the first time in months and see my name on a recent post, cool! I unfortunately don't have the tools to open any of the calculators (my torx bits are all too big), otherwise I would love to help out with documenting. Also you're right there's a typo for the 83P SE, it should be just "I-0901"

Yep, that's one of them.

Need to report what's inside your grayscale calculator, but can't open it?

[edit] Please see the Z80Test project thread here.

For TI-82 STATS, TI-83, TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, and TI-84 Plus Silver Edition users, you can instantly get reportable results using CalcInfo, which computes which chips your calculator contains using Z80Test's results.

The latest release of Z80Test, version 6 at the time of posfing, can identify your CPU, ASIC, and LCD driver. BZ80Test, included with Z80Test, interprets results for you, so you can see what each test did and how your calculator responded. BZ80Test alters the contents of L1, so either run the assembly Z80Test program or break BZ80Test at the first screen if you were asked to send L1 instead of interpreted results.

To run the assembly Z80Test program from the TI-83 Plus series, TI-84 Plus series, or TI-86 home screen, grab the Asm( token from the CATALOG, select Z80TEST from the PRGM menu, and press ENTER. You should have `Asm(prgmZ80TEST`. Press ENTER, the screen will flicker, and results will appear in list L1. For the TI-83 and TI-82 STATS, grab the Send( token from the CATALOG, press 9, then select Z80TEST from the PRGM menu. You should have `Send(9prgmZ80TEST`. Press ENTER, the screen may flicker, and results will appear in list L1.

An additional program, FlashFun, can coarsely identify your Flash chip if you're using a TI-83 Plus or TI-84 Plus series monochrome calculator. There might be cases where it clears your RAM (since it relies on flash unlocking), so don't run it on anything important without a backup. If BFLASHFN (the results interpreter) doesn't give any output, let us know what's in L1!

Even if you aren't one of the users being bullied, you should still submit your Z80Test/BZ80Test results!
You can submit your results to my Google Forms page here!

If I didn't mention someone, that's probably because I didn't find them in the post-2020 posfs on Posf Your Calculator Collection and they don't have a MyCalcs account. As far as you specifically, you gave an excuse earlier in SAX, so I wasn't going to pester just yet.

So... uhh... which calculator is it that you need it run on?

Haha! It's so sad that bastard is glued shut rather than screwed!
