EMG HUNOR 81
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 at the Budapest International Fair '73. The hungarian industry was not able to
produce state-of-the-art integrated circuits at this time, so these contains Texas Instruments CPU. The display was unusual, built
from 9 pieces of japanese incandescent display elements, but due to problems with this construction, later replaced by
VFD tubes.
