Híradástechnika K-86

Brief History
Mass production of the hungarian-canadian pocket calculators which were introduced at the Budapest International Fair 1973, was started in the second half of the year. The simplest model (K-831) was produced in high quantities, the 10-digit version was the second, but only 100 pieces of K-86 were made. These were almost identical to Bowmar’s and United States’ first pocket calculator, the Bowmar 901B, the only difference is the display and design of the housing.
