Features[edit | edit source]
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 design[edit | edit source]
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.
