[1] Headquartered in Paderborn, Germany, it became the fourth largest computer company in Europe, and a worldwide specialist in banking and point-of-sale systems.

The Rheinisch-Westfälisches Elektrizitätswerk (RWE) in Essen showed interest and trust in his ideas, so they gave him 30,000 D-Mark.

Because of their success, the Labor für Impulstechnik delivered to major companies like the Wanderer-Werke in Cologne and the Compagnie des Machines Bull in Paris.

It was very successful, and in 1978, the Heinz Nixdorf AG sales were a billion DM, with over 10,000 employees worldwide.

With the thought of training his employees, Nixdorf founded a trade school in 1969, which was done in 1972: the Bildungszentrum für informationsverarbeitende Berufe (b.i.b.).

Heinz Nixdorf was an ambitious sportsman, and as he wanted his employees to do sports as well, he built the Ahorn-Sportpark in Paderborn right next to the company's central office.

[2] TCSC's products included its own operating systems for IBM and compatible mainframes, EDos and EDos/VS; it had licensed the DATACOM/DB database from Applied Data Research (ADR) to run under them.

Nixdorf refused an offer from the Volkswagen AG, but agreed with the Deutsche Bank which gave the concern 200 million D-Mark for 25 percent.

In 1989, Nixdorf decided to pull out of the IBM-compatible mainframe market, in order to focus on Unix.

It transferred its Nixdorf 8890 line of clone IBM mainframes to Comparex Informationssysteme GmbH.

Nixdorf decided to cancel all work on the next release of its Edos, since they did not want to commit to maintain any new version in the years to come.

Thousands of people were made redundant in Paderborn the same year, because Siemens sought to streamline the company.
