"school bus yellow" color scheme.
construction of the TI-Nspire makes use of just 2 printed circuit boards
one for the gray-scale LC-Display and power supply and another one for the computing unit.
|The frontside of the
PCB's reveal the construction of the 240 * 320 pixel gray-scale
LC-Display and the ARM9 based 32-bit RISC processor.
|The brain of the
TI-Nspire is actually a System-on-Chip based on the ZEVIO
architecture from LSI Logic.
We assume that the 208 pin housing hosts a 90 MHz ARM9 32-bit RISC processor.

image processing technologies to reveal the name

|The TI-Nspire uses three
different memory chips, a 256k*16 NOR Flash-ROM, 32M Bytes
and 16M*16 SDRAM. The clock frequency of the SoC is 27 MHz.
