The backside of the TI-Nspire CAS+ prototype looks identical to the finally released TI-Nspire CAS.
The internal construction of the TI-Nspire CAS+ makes use of just 3 printed circuit boards (PCB's), one for the gray-scale LC-Display and power supply, one for the computing unit and the keyboard.
The frontside of the PCB's reveal the construction of the 240 * 320 pixel gray-scale LC-Display, the TI-OMAP and a total of three different memory chips.
The brain of the TI-Nspire CAS+ prototype is actually a System-on-Chip based on the OMAP architecture from Texas Instruments. We assume that the tiny housing hosts a 78 MHz ARM9 32-bit RISC processor.
The TI-Nspire CAS+ uses three different memory chips, a 256k16 NOR Flash-ROM, 32M Bytes NAND Flash-ROM, and 16M16 SDRAM. The clock frequency of the SoC is 12 MHz.

The 320 * 240 pixel gray-scale LC-Display needs a total of three drivers. We located this Novatek NT7702 row-driver and two unidentified column-drivers.
