What would become RC began as an advisory board formed by the Danish Akademiet for de Tekniske Videnskaber (Academy of Applied Sciences) to keep abreast of developments in modern electronic computing devices taking place in other countries.

Led by Niels Ivar Bech, the group was also given the details of the BESK machine being designed at the Swedish Mathematical Center (Matematikmaskinnämndens Arbetsgrupp).

Bech also sold GIER machines to the Eastern Bloc nations, starting with Czechoslovakia, Hungary, Poland and Bulgaria, and later Romania, the East Germany, and Yugoslavia.

RC was also home to Peter Naur, and DASK and GIER became well known for their role in the development of the famous programming language ALGOL.

After the first European ALGOL conference in 1959, RC began an effort to produce a series of compilers, completing one for the DASK in September 1961.

Christian Andersen and Peter Schyum Poulsen, another RC employee, wrote the first introductory text on the language, Everyman's Desk ALGOL, in 1961.

Brinch Hansen also worked with Charles Simonyi and Peter Kraft on the RC 4000's Real-time Control System.

During the 1980s, RC produced the RC700 Piccolo, the RC750 Partner, and the RC759 Piccoline systems, which were sold to Danish schools mostly, and to some businesses in Denmark and abroad.
