Texas Instruments introduced at the 2011 T3 International Conference held on February 25-27 in San Antonio, TX with the TI-Nspire CX and TI-Nspire CX CAS their first graphing calculators with full color, backlit displays. Since its introduction in 2007 the original TI-Nspire with Clickpad received quite some criticism and it took just two steps in evolution to overcome them completely:
• Crowded, confusing keyboard: Introduction of the TI-Nspire with Touchpad in April 2010.
• High consumption of disposable AAA batteries: Rechargeable Li-Ion battery available as
option for the TI-Nspire with Touchpad.
• Low-contrast of the display and rather bulky housing: Announcement of the TI-Nspire CX in February 2011.
• Lack of 3D graphing: Upgrade of all TI-Nspire calculators to Operating System 3.0 (April 2011).
But there is no free lunch, the new TI-Nspire CX handhelds
shed some size and reveals an outstanding design but the concept of replaceable
keyboards are gone – and with it the TI-84 Plus
The TI-Nspire CX and its sibling TI-Nspire CX CAS feature a 16-bit, 320 x 240 backlit display capable of 65,536 colors. The scanning process used for the images provided by the Datamath Calculator Museum can’t reproduce the one-of-a-kind quality of the calculator screen and we had to invest in some new equipment to photograph it accordingly.
Casio introduced already in October 1985 with the
fx-7000G the world’s first graphing
calculator and created in 1996 with the CFX-9850G a variation with a 3-color
screen, but it took till January 2011 to reveal with the Casio Prizm (fx-CG10,
fx-CG20) the first models with a high-resolution (384 x 216 pixels) full color
Texas Instruments announced together with the TI-Nspire CX family a new Wireless Network Adapter to connect the calculators with the TI-Nspire Navigator system. A huge progress compared with the previous TI-Nspire Wireless Cradle used for the original TI-Nspire calculators.
The TI-Nspire CX Docking Station
charges up to 10 units in 6 hours. It can also be used to update the Operating
Systems of the calculators.
The new TI-Nspire Operating System 3.0 allows not only 3D graphing but the import of real-world images to view, graph and analyze for example the outline of the path of a basketball. The new OS is compatible with the original TI-Nspire calculators, too. Obviously it will display color images only in grayscale. The new TI-Nspire Lab Cradle requires the new Operating System 3.0 (introduced in May 2011) or higher.
reduce theft of school-owned TI-Nspire CX's a
"school bus yellow" edition will be available.
