Regnecentralen (RC)

Regnecentralen, or RC for short, was the first Danish computer company, founded on October 12, 1955. Through the 1950s and 60s they designed a series of computers, originally for their own use, and later to be sold commercially. Descendants of these systems sold well into the 1980s. They also developed a series of high-speed paper tape machines, and produced Data General Nova machines under license. They are arguably the oldest remaining "computer-only" company in the world. Regnecentralen was acquired by ICL in 1989.
