The first version of Edos was released in 1972, in response to the announcement by IBM that DOS Release 26 was the last DOS release to be supported on the System 360, and future DOS Releases would support System 370 machines only.

When in 1980 Nixdorf bought TCSC, Nixdorf sought to continue the licensing arrangement; ADR and NCSC went to court in a dispute over whether the licensing arrangement was terminated by the acquisition. ADR and Nixdorf settled out of court in 1981, with an agreement that Nixdorf could continue to resell ADR's products.
356:. However, while Comparex was willing to take over the hardware business, it did not want the responsibility of maintaining the Edos operating system, preferring instead that its customers purchase DOS/VSE or MVS from IBM. Nixdorf decided to cancel all work on the next release of Edos, since they did not want to commit to maintain any new version in the years to come.

TCSC enhanced EDOS to become EDOS/VS, which was announced in 1977 and delivered it to beta test sites in 1978. In May 1977, TCSC announced it would release Edos/VS in response to IBM's release of DOS/VS Release 34 and
Advanced Functions-DOS/VS. Edos/VS was based on IBM's DOS/VS Release 34, and
