EMG HUNOR 102
Brief History
From the early 1970s, EMG (Factory for Electronic Measuring Instruments) was developing a new IC-based calculator family.
The first member (Hunor 81) was announced in 1973, but due to problems with the display, was soon replaced
with the Hunor 81B. EMG planned to use Texas Instruments' new calculator-ICs with the same pinout as the TMS0105 has,
so a new PCB was developed for the new series of desktop calculators. All 6 models of the series (Hunor 81B, 82, 83 and Hunor 101, 102, 103)
have built from identical parts. The models and features are as follows:
- Hunor 81B (8 digits), Hunor 101 (10 digits): changing sign, 5 different fixed point and a floating point setting
- Hunor 82, Hunor 102: calculating percentages and thousandths, mark-ups and mark-downs, double 0-button, 5 different fixed point and a floating point setting
- Hunor 83, Hunor 103: changing sign, square and square root capability, only floating point display
