HotCalc_Back.jpg (116713 Byte)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.

wpeE.jpg (36711 Byte)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.
