Constructed in 1959 by Jacek Karpiński and Janusz Tomaszewski it was the world's first transistorised differential equations analyzer.

Karpiński built the device at the Polish Academy of Science's Institute of Automatics.

AKAT-1 aimed to simulate various complex dynamic processes like thermodynamics, heat transfer or a shock absorber's mechanics.

The panel designed by leading Polish artists Emil Cieślar, Olgierd Rutkowski, Stanisław Siemek and Andrzej Wróblewski at the Warsaw Academy of Fine Arts had been considered to 'innovatively merge all functions in a congruent and attractive form that anticipated the future trends'.
