Alco Mickey Math (Model 18)
Brief History
The fairly popular Mickey mouse was a great opportunity to produce large quantities of an algebraic version of the six-digit circuit developed by Omron. It was used in the Omron 86-like model 606, and in a Mickey Math named (model DI 67) calculator specially designed for children. Omron marketed this model in the domestic market, and an american company, Alco distributed it abroad. The very robust, durable calculator came with a storybook-like user guide. While model 606 operated with two, the DI 67 used four penlight batteries.
In terms of their knowledge, except that the new ones have algebraic logic, they were the same as the Omron 60.
