Texas Instruments officially announced today its new "TI-84 Plus CE"
calculator for back to school 2015 discovered in a previous news
, which will be logically demonstrated at the T3 international conference in March 2015 at Fort Worth in Texas. Availability is scheduled for spring 2015.
If we understood well at the journées APMEP
and the salon Educatec-Educatice
last November, France will get a specific model, the "TI-83 Premium CE"
. Remains to be seen whether this will be a simple francisation the TI-84 Plus CE keyboard or if there is something else lurking back there which could justify the use of the 'Premium'
In all cases these models are sharing the 'CE'
suffix and apparently developed simultaneously. So they should share many similarities and the following lines should be valid for both models.
The official page therefore presents a calculator equipped with a 16-bit 320x240 pixels backlit color display, the same as the one in the TI-Nspire CX and TI-84 Plus C Silver Edition. The operating system clearly seems to be an evolution of the one in the TI-84 Plus C Silver Edition, since we're noticing exactly the same user interface. As a consequence, one remaining question would be whether the defects of this previous model have been fixed or not, and in particular its extremely slowness due to using the same processor as the one used in the latest monochrome TI-84, a z80 to 15MHz, with a display needing (320×240×16)/(96×64×1)=200 times more data to be processed for each refresh.
The model is described as 30% lighter than the older TI-84 and much thinner. Indeed, the AAA batteries disappear in favor of a rechargeable battery.
It will be available in different colors.
USB connectivity is present, this time on the side of the calculator, with a mini USB A/B connector, together with a charging LED.
The Vernier website, a long time partner of Texas Instruments, has also been updated and tells us a little more about this new model.
On one hand, TI-84 Plus C Silver Edition applications do not seem compatible with the TI-84 Plus CE. Indeed, in order to use Vernier sensors you'll need to have the new EasyData 5.0 application. EasyData 4.0 equipping the TI-84 Plus C Silver Edition would therefore be incompatible, which may be an indication of more or less interesting OS and hardware changes. If in addition we made the connection with the 4.x numbering of the TI-84 Plus C Silver Edition operating systems, one could infer that the new TI-84 Plus CE will use a new 5.0 version of the operating system.
Furthermore, it is stated that the TI-84 Plus CE will not work with Vernier LabPro and TI-CBL2
interfaces, nor with TI-Navigator hubs
. This could indicate the removal of the mini-jack 2.5 historical connector which was the only way to connect these devices. By extension, TI-Robot
would also be incompatible.
Vernier also tells us about something else, the "TI-Charging Station CE"
, which can store up to 10 TI-84 Plus CE while recharging their batteries, apparently using contacts which must be located on the bottom of the calculators - ideal for classroom use.Source with more pictures : https://tiplanet.org/forum/viewtopic.php?p=175678&lang=en#p175678
