FeaturesEdit

Unlike many simple basic calculators of the day, the Accumatic 306 provides the user with expanded functionality, specifically keys for using a stored constant for pi, squaring numbers, taking square roots, and for 1/x. The addition of these four keys provides much greater flexibility for the user and enables the calculation of more difficult equations while increasing user input speeds.

Internal designEdit

The overall board design of the calculator is very simple, cantered around the Hitachi HD36360S calculator ASIC, pared with a GICO GK320 spring over leaf keypad. A tube type vacuum fluorescent display module, the Futaba 9-CT-085L, is used in this model and provides 8 numerical digits along with a ninth digit to indicate sign and overflow.
