Calculators: Indian brands

In India calculators manufacturing started in the early 70s. In the 80s, foreign brands calculators were massively available, therefore some rare models were made during the 80's. The majority of the calculators manufactured in the country were destinated to the domestic market and because the small production quantities they were quite expensive. Only few (Calcom) were exported, so finding information and indian calculators is difficult.
