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.

This TI-Nspire CM-C was introduced in October 2011 for the Chinese market and sports not only cosmetic differences but differs from the technology, too:

Flash-ROM reduced from 64M Bytes to 32M Bytes.
Battery with lower capacity.

No Press-to-Test LED indicator.
No network adapter port.
No docking connector for Navigator Wireless Cradles, Lab Stations and Docking stations.

Dismantling this TI-Nspire CM-C manufactured in September 2011 by Inventec Corporation in its Pudong Campus in Shanghai, China reveals a design similiar to the original TI-Nspire CX centered around a tiny System-on-Chip.

Don't miss the early prototype of the TI-Nspire CM-C labelled TI-Nspire CM (Chinese Language).
