Advance Electronics Mini Executive

The Advance Electronics Mini Executive is an arithmetic calculator with 8 digits precision and algebraic logic. It has 4 functions, 17 keys, and an LED (light-emitting diode) display, typical of calculators of this era. The calculator was manufactured in UK.

The float/fixed point and constant (K) switches required a press-and-twist action, a bit like a bayonet light bulb fitting, and were quite fiddly. The buttons themselves had a distinct clickiness, but with only a limited travel. Apart from the sliding on-off switch being a bit temperamental the calculator was well-made and had a futuristic brushed aluminium fascia.

Personal note: This was the first pocket calculator I ever used. My father bought it for his office. It was a choice between the Advance Executive and one of the Hewlett-Packard models which seemed very expensive. I seem to remember there were really no other options, this being before the boom in pocket calculators that was to occur a couple of years later.

It was amazing to be able to do arithmetic calculations so effortlessly, and at no cost, and with such a compact device. You could do as many calculations as you liked, and quickly, unlike the electro-mechanical adding machines that used to consume paper rolls. It was quite expensive to run off batteries so it was almost permanently attached to its mains-powered cradle. I saw this machine two or three decades later when visiting my father at his office and it was still working.

Note: Think this is the model my Dad had. First calculator I used.
