It is 1976 and you are an executive in a top international business, but you need one of those new fangled pocket calculation machines. Well Accuron have the machine for you, it's even called the Executive! It has the four basic mathematical functions plus percentages (important for executives no doubt) and a memory. Numbers are displayed using LEDs. Unfortunately my Accuron Executive does not seem to work anymore though i'm not an executive anyway so no harm done!
