feel familiar with this colourful calculator? Compare it with the first
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 similiar to the TI-106 but makes use of a Sharp LH3154 single-chip calculator circuit instead the LH3135MR.
A similar calculator was sold with the Fun Calc based on the rare TI-7140.
