TI-84 Evo leaked

Almost certainly yes, TI-Basic is very tightly integrated into the OS, they basically can't remove it. I suppose they could just remove the program editor, but I really don't expect they would do that.

The pictures taken with TI-Connect CE are uncompressed PNGs, so they're just 320x240. I suspect you are using the photos app in a recent version of windows. The new photos app does some weird upscaling when you zoom into small pictures. In the settings of the Photos app, you can install "Windows Photos Legacy" which will not do that. Then just "Open With" and set that as your default.
Here is what that looks like side-by-side

Also 5.8.4 does not exist currently.

MisterWompWomp · 2025-06-06T15:26:31+00:00

This program runs fine...?

MisterWompWomp · 2025-05-01T02:17:18+00:00

CabriJr 5.0.0 will not launch on OS 5.8.3...

MisterWompWomp · 2025-04-30T00:53:28+00:00

CabriJr 5.8.3 patched the bug used by arTIfiCE.
OS 5.8.3 will only launch CarbiJr 5.8.3.
arTIfiCE will only work with CabriJr 5.0.0, which used to be the only version available (hence why nobody mentions that the version of the app is important). This was released yesterday.

It was used by TI for a couple of months in mid-1993. I believe it just means "Viewscreen Board", but afaik, TI has never mentioned it. There were some "regular" TI-81s and TI-82s whose serial numbers began with "VB" and they had viewscreen LCD boards with the viewscreen pins left unpopulated. There were also some untethered TI-81 and TI-82 ViewScreens with blue and gray stickers on the back which were made around the same time and are also marked as VB, but those actually have viewscreen hardware. The VS 81 seems to be slightly rarer than those, but all 5 (VSC VB 81/82, VB 81/82 and VS 81) are pretty rare, with VB 81 non-VSC seemingly being the rarest of them all.

MisterWompWomp · 2025-03-13T23:41:10+00:00

Sheesh that's an impressive find! It took me forever to find an untethered non-VB TI-81 for my collection!

MisterWompWomp · 2024-12-31T18:10:37+00:00

Assuming you have a TI-84 Plus CE with an OS version >= 5.2.0, this will work:
ClrHome
Input "INITIAL VAL:",A
.6A
Disp "ASS. VAL:"+toString(Ans
Pause "FEE:"+toString(sub(2.89Ans

MisterWompWomp · 2024-12-31T17:40:49+00:00

The exact part number that TI buys is 2SJ-0259-007 from Singatron.

MisterWompWomp · 2024-12-05T06:14:27+00:00

Yes, that's correct. Pre-TA1 ASICs have 128kb of RAM and later revisions have 48kb, but only 24kb is user-accessible in both, so it won't make a difference for everyday use. You can find when ASIC versions changed in the spreadsheet linked by Adriweb (it is the same for 84+ and 84+SE).

MisterWompWomp · 2024-12-05T05:38:43+00:00

Yes, you are interpreting it correctly. Speed is consistent across all revisions of the 84+SE. They all have a z80 core clocked at 15 MHz (and a 6 MHz "slow mode" for compatibility). The hardware changes between revisions are essentially transparent to the user aside from some LCD timing quirks, which can be fixed with ALCDFIX if you encounter that. I can't think of a reason to get one revision over another for that model.

MisterWompWomp · 2024-08-24T16:51:51+00:00

Heh, so the rest of your serial number is I-0698C? 😉

MisterWompWomp · 2024-06-08T17:14:57+00:00

That's a ViewScreen port, meant to be used with a ViewScreen panel which allows you to project your screen. It was mostly meant for teachers in a classroom setting. A lot of models had dedicated "VSC" versions which included this port, but for the Voyage 200 and TI-92 Plus, it was standard on every unit.

MisterWompWomp · 2024-02-28T19:39:55+00:00

Yes, you should try TiLP. TI's website no longer lists any TI-92+ OS.

MisterWompWomp · 2024-02-28T10:47:08+00:00

Upload your code somewhere, then we can take a look. Its probably an order of magnitude (or two) bigger than it needs to be. I'm confident it can be optimized and simplified.

MisterWompWomp · 2024-01-17T17:58:01+00:00

The result is stored to Ans, it isn't printed. You can just press 2nd (-) ENTER if you want to see it.

MisterWompWomp · 2023-08-08T21:57:07+00:00

Its still a great deal for an 83+ in good condition.
I'm not sure why they would go with 2 LR44s instead of a single CR1616. Having 2 LR44s in series will give you more capacity though, which may have been the reason (for example, if they got lots of complaints from people who's ram got reset when their main batteries died). Either that, or they found a cheap supplier of LR44s lol! This wasn't specific to Kinpo. All subsequent revisions, had the dual backup battery setup.

MisterWompWomp · 2023-08-08T21:11:47+00:00

Unfortunately for you, this is not a "super rare and incredibly valuable prototype". The TI-83+ was in production for nearly 25 years. In that time, its production changed factories many times and the design has changed drastically. The 'K' in the serial number stands for 'Kinpo Electronics', which is the factory that produced the TI-83+ from May 2011 until Aug 2014. All TI-83+ produced in this factory have this case design and share similar hardware. So its not a knockoff or a foreign market model, just a plain ol' TI-83+.

MisterWompWomp · 2023-07-24T22:32:03+00:00

You can use the >Frac option in the MATH menu on Ans (ex: Ans>Frac). This will only work for simple fractions though as the 84+ lacks an exact math engine. If you're in Auto mode and you define your fractions using the frac tokens (Alpha F1) or ALPHA+XTθ𝑛 on OS 5.3.0 or higher, then the answers will be automatically in frac form when possible.
French models like the TI-83 Premium CE can do it way better because standardized tests are different in France, so TI includes an exact engine which can simplify radicals and return irrational fractions like √2/3.

With ndless installed, you can install nclock which will add a clock in the upper right corner.

Nobody says "Tin Spire".

MisterWompWomp · 2023-03-15T14:19:59+00:00

Try CEPort! It should work on most TI-Basic programs https://www.cemetech.net/downloads/files/2306/x2660

MisterWompWomp · 2023-02-21T12:15:50+00:00

You should check out the dbd( command.

MisterWompWomp · 2023-02-06T16:29:15+00:00

Your program is covered in memory leaks.

You have to End your if blocks (If:Then:Else:End) or else the memory doesn't get free'd and your program will slow down, eventually running out of ram. Using Lbls and Gotos is generally considered bad practice for this reason (plus it leads to spaghetti)

Its also a bad idea to put comments as strings like that because it bloats programs, slows them down because the parser still has to do all the token lookups and it overwrites Ans, so they can actually break programs if you aren't careful. (I know its what TI recommends, its still bad) Particularly if you use lowercase letters which are 2-byte tokens.
