The TI-84 Evo, the latest model in the TI-8x series, has just leaked online (on its official Amazon page). TI has yet to announce anything, so this seems to be an accident. We can only now guess that they are getting ready to announce it soon.




Here's what we know so far:

1. It is the successor to the TI-84 Plus CE Python, and as such, we can expect all the same features software-wise (Graphing, Flash Apps, TI-Basic, Python, etc.) It is yet to be confirmed whether flash apps will be included as an indiscrete part of the OS like the TI-82AEP or if they will continue to be standalone apps.
   
2. Like the TI-84PCE, it will have a rechargeable li-ion battery and color 240x320 TFT LCD.
   
3. It will feature a brand-new ASIC. According to the listing, this processor is said to be "3x faster", which would imply 144 MHz equivalent... more than standard eZ80 implementations. Maybe this will be an ARM processor that both emulates the ez80 and runs the Python interpreter on a single ASIC ?
   
4. It will likely have a USB Type-C port
   
5. It is said to have ”50% more graphing space”, which certainly means they removed the arbitrary border around the graphing area.
   
6. It will feature an Icon-based home screen

The key layout seems to have changed in a few significant ways, which provide clues about calculator functionality:

• Firstly the ON key now features a home icon to go back to the home screen, which is no longer the “calculator” app.
  
• The X^^-1 key and ^ keys have been merged into a single X^n key, making way for the new <> key. The TI-83 Premium CE has always had this key, which is used to switch between exact and approx answers. This seems to suggest that the Evo could have an exact math engine like the TI-83 Premium CE.
  
• The APPS key has been replaced with a MathPrint fraction, which had previously been relegated to a 2nd function since OS 5.3.0. The home button will serve a double purpose as an APPS key.
  Interestingly, the MODE button has not been removed despite the home screen containing a gear icon. Perhaps these will both lead to the same menu, or there will be a new “settings” menu, distinct from the MODE menu.

It seems the TI-84 Evo will initially come in 7 color variants:

• White
  
• Lavender
  
• Raspberry Metallic
  
• Silver Metallic
  
• Teal
  
• Mint
  
• Pink

While the overall shape of the calculator appears to be the same as the TI-84 Plus CE, it lacks the iconic screen bezel, which means the case plastics have been completely redesigned. Hopefully the new design will fit seamlessly into old TI-84 Plus CE Docking Stations and the slidecases will be interchangeable.

The TI-84 Evo, like its predecessors, is approved for standardized exams, including the ACT®, SAT®, IB®, and AP® courses.

This better have assembly support, or else it'll just be a brick that can surprisingly do math sort of fine.

As always, great naming follow up! TI-84 Plus -> TI-84 Plus SE -> TI-84 Plus CSE -> TI-84 Plus CE -> TI-84 Evo.
The lack of the 'Plus' notation clearly means this will lack FLASH right? 😛
I find it amusing the arrow keys resemble Zero's choice.

Jokes aside I'm pretty excited for this. USB C, exact math (I thought this wasn't allowed in the US?), and no bezel around the graph! I wonder how well they've handled security on these devices given the Nspire recently had a hardware exploit discovered.

Raspberry Metallic and Teal are by far my favorite colors and I might have to buy both... which are you getting?

The OS looks very much like the numworks, but it will probably be very protected from installing games (maybe TI won't even allow data transfer?). In the meantime, someone should risk it and try buying one to see what happens (never mind, i just noticed it is out of stock, oops)?

There is a "link" key, so that's definitely not the case.

Ugggggh just when the gui rewrite for CEmu was nearing completion

I like the design and colors, but the interface is really wacky (and sort of a Numworks ripoff). I wonder how this will impact classrooms where students are expected to replicate key sequences...does the "math" icon take you to something like the homescreen for the TI-84+ CE and all of the others before it? Or did they change things everywhere else too? Hopefully it adds some new functionality rather than just relocating existing features and looking more modern...

Also, no apps key means maybe apps are integrated into the home view now, and you scroll to access them?

Seems more like a marketing gimmick that someone who has never used a calculator dreamed up

All those CE projects that were never finished are soon to be dead Oh well!

Interesting - is it definitely to replace the CE, given exact math?

Either way will be very interesting to see what TI's announcement will be 🙂.

Do you guys think we'll get DoorsEvo???

KermMartian should call it Doors CX to confuse everyone who wanted a shell for the TI-Nspire series.

I highly doubt this will kill CE projects, the community and projects built around it are huge, and it will probably be very hard to get games on. As for DoorsEvo, we don't have DoorsCE yet ☹️
doorsCE when

The amazon page changed and the price went up from $131 to $160. A release data was added of April 28th!

I [pre]ordered it for $131 - I wonder if they'll try to make me pay the difference.

They better not because I did the same.

I also preordered before it was taken down, at $131

where did u order this from? its not on amazon anywhere
oh was it taken down?

The page was deleted.

Here's some more proof the TI-84 Evo exists.
These are fake, by the way.

Holy crap!
