integraalarvutused

Integraalarvutused are a category of electronic calculators developed in the 1960s and 1970s. The term "integraalarvutus" is Estonian for "integrated calculator". These devices were the first to use fully integrated circuits, which enabled them to perform arithmetic operations more quickly and accurately than their predecessors.

The first commercially available integraalarvutus was the Cal Tech CT-35, released in 1970. It was developed by Cal Tech, an Estonian electronics company. The Cal Tech CT-35 used a single integrated circuit to perform arithmetic operations, and it could add, subtract, multiply, and divide numbers.

Integraalarvutused were widely adopted in Eastern Europe during the 1970s. They were used in a variety of applications, including business, education, and science. The devices were relatively expensive, but they offered a level of accuracy and speed that was not available with earlier calculators.

The development of integraalarvutused laid the foundation for the modern electronic calculators used today. The use of integrated circuits in these devices enabled the creation of smaller, more portable calculators that could perform a wider range of calculations. The technology developed in integraalarvutused also paved the way for the development of computers and other electronic devices.

The production of integraalarvutused ceased in the early 1980s, as more advanced and affordable calculator technologies became available. However, the legacy of integraalarvutused can still be seen in the modern electronic devices that have developed from their technology.
