In the late 1970s Data General was sued (under the Sherman and Clayton antitrust acts) by competitors for their practice of bundling RDOS with the Data General Nova or Eclipse minicomputer. When Data General introduced the Data General Nova, a company called Digidyne wanted to use its RDOS operating system on its own hardware clone. Data General refused to license their software and claimed their "bundling rights". In 1985, courts including the United States Court of Appeals for the Ninth Circuit ruled against Data General in a case called "Digidyne v. Data General". The Supreme Court of the United States declined to hear Data General's appeal, although Justices White and Blackmun would have heard it. The precedent set by the lower courts eventually forced Data General to license the operating system because restricting the software to only Data General's hardware was an illegal tying arrangement.
