The
Math
Explorer (aka TI-12) is another calculator introduced by Texas Instruments to perform
fractional arithmetic for elementary school.
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 housing was used on the enhanced TI-32 Explorer Plus and the new TI-34.
Don't miss the innovative TI-15 Explorer introduced in the year 1999 and the Graphing calculator TI-73.
Stokes Publishing Company, Inc. based in Sunnyvale, California sold a companion for the teacher, view the Intermediate.
