This KIT calculator MINI 73 was sold June, 1976 by the Switzerland company Ellenberger Electronic AG. The price tag gave a whooping SFr 396.50, about US$ 200.
The manual of the kit stated "don't compare it with the cheap calculators manufactured in Japan" and used a very rigid construction based around the "calculator-on-a-chip" TMS0105.
The calculator housing is known from the German MBO Junior.
According to fellow collector Frank Boehm this calculator was manufactured by DITTEL.
