The Math Explorer (aka TI-12) is another calculator introduced by Texas Instruments to perform fractional arithmetic for elementary school. 

TI-12_N0898_PCB.jpg (128959 Byte)Dismantling the TI-12 Math Explorer reveals a typical design of the late 1990's based on a single-chip calculator circuit attached directly on and electrically interconnected to the printed circuit board (PCB), instead of undergoing traditional assembly and packaging as an individual Integrated Circuit. This technology is called Chip-On-Board (COB) assembly.

Compare this stylish calculator with the first version of the Math Explorer.

The same hosuing was used on the enhanced TI-32 Explorer Plus and the new TI-34.
