The BC-1201 was Toshiba's entry-level first-generation electronic calculator, intended to provide a low-cost but high quality calculator that was priced within the reach of small business budgets. The calculator provides the basic four math operations, with a capacity of twelve digits. The display is provided by individual Nixie display tubes. The BC-1201 provides a user-settable fixed decimal point location at 0, 1, 2 and 3 digits behind the decimal point, as well as a switch-selectable constant function that operates in multiplication and divsion operations. The logic circuitry of the calculator is entirely discrete transistor technology, with the logic distributed across seven plug-in circuit boards.
