You
feel familiar with this colorful calculator? Compare it with the first
generation TI-106
and the later TI-1722+ aka CLEAR CALC. The
featured calculator was manufactured by Cal-Comp
Electronics, Thailand early in 1995.
Dismantling
the Texas Instruments Hot Calc reveals a typical far-east design of the early
90's. The printed circuit board (PCB) of the calculator looks very similar to
the TI-106 but makes use of a Sharp LH3154 single-chip calculator circuit
instead of the LH3135MR.
A similar calculator was sold with the Fun
Calc based on the rare TI-7140.
