Siemens Nixdorf Informationssysteme

The Siemens Nixdorf Informationssysteme AG (SNI ) was a German universal provider in the field of data and information technology and put both PCs and supercomputers, PBXs ago. In addition, ATM and POS systems were part of the portfolio. SNI was Europe's largest provider of computer and software solutions was to split it into several successor companies. The best known are Fujitsu Siemens Computers and intervening on the market today Wincor Nixdorf ( ECRs ).


On October 1, 1990, Siemens acquired the majority of Nixdorf ordinary shares and led the Nixdorf Computer AG (Paderborn ) with the range of data and information technology of Siemens AG ( Augsburg and Munich) for Siemens Nixdorf Informationssysteme AG (SNI) together. 1992 Siemens increased its shareholding in the SNI to 100 percent and incorporated them into the Siemens AG. After a painful downsizing with the loss of several thousand jobs in Paderborn, Germany in the early 1990s, SNI was around the middle of the decade stabilize as Europe's largest computer company. In 1995, the services and solutions business in the fields was information technology and telecommunications released from the company SNI and together with parts of Siemens AG, Siemens Business Services GmbH & Co. OHG (SBS ), then transferred to and based in Paderborn and Munich.

On 1 October 1998, the SNI was dissolved as a corporation and fully integrated into the Siemens AG, with further parts migrated to SBS. The name Siemens Nixdorf was still alive for one more year in the form of Siemens Nixdorf Banking and Retail Systems GmbH.

The personal computer division was introduced into a joint venture with Fujitsu, the Fujitsu Siemens Computers GmbH, headquartered in Munich, were involved in both companies, 50 percent. On April 1, 2009, Siemens sold its stake in the company to Fujitsu. Since then the company sells computer products under the brand names "Fujitsu " and is by merging FSC ( USA), FSC (EMEA) and FJ (Asia) Fujitsu Technology Solutions (FTS ) the world number three, behind HP and Dell, ascended.

Products and services


Among other things, the company was during the advent of the PC of the largest German manufacturer of computer monitors and cut in tests in the trade press for the most part well.

Due to the BNC-/D-Sub-Modus succeeded to present a very accurate color temperature and color accuracy. It helped an improved version of interlacing.

The monitors from Siemens were first produced in the 1980s Tandberg Data. This company was since about 1982 one of the first who gave the appearance of green or orange markings on a dark background with a frame rate of 50 or 60 hertz and the then innovative, now familiar representation of black characters on a white background introduced. This required a refresh rate of 70 Hz or faster and a correspondingly more powerful electronics. Also Nixdorf produced in Germany.

Following the acquisition of Siemens Nixdorf by was produced largely in Taiwan according to specifications from Germany. Both the Tandberg own ranks as well as monitors with Siemens branding received in many computer magazine tests (eg CHIP) high marks for ergonomics and image quality. Siemens Nixdorf monitors were also among the first who implemented the emerging since the mid-1990s radiation standards.


In the work of workstations ( WA) in Augsburg keyboards were manufactured stood out from the products of the then market leader Cherry with a shorter key travel and a defined pressure point. A special feature of the production were the key caps that initially assembled without inscription and were labeled only on the finished keyboard with a laser. In this way, the country variants without additional measures in warehouse or production could be produced.


Siemens had mainframe as the System 7500 family and supercomputers such as the VPP50 on offer. The models C40 from the system family 7500 offered in February 1991 crucial innovations such as the support of 290 screens instead of the previous 160 models the number H60 from the same family of systems have been extended to a dual processor model. The H120er models got a powerful console processor, this could (after SNI details ) up to 2000 meters to be installed by a computer. This was made possible by the " block type multi-channels 2 " of SLI, this allows data transmission of up to 4.5 MB / s This has ensured a faster access to external high performance peripherals. It was the BS2000 operating system used in all mainframes.

Many customers of SNI had the 8870 mainframe developed by Nixdorf and its successor Quattro with the standard business software Comet in conjunction with the operating system Niro's in use.

Personal computer

There was, inter alia, the model series and Scenic Xpert. In the latter, it was inexpensive PCs for residential customers. In a separate development department at the factory for Workplace Systems in Augsburg created for that time very innovative concepts such as the slot CPU or a Micro Channel computer, but could not prevail on the market.


Since 1990 there were notebook PCs from Siemens Nixdorf, which specifies by in-house developers in the Augsburg works for systems (WS ), adapted by customizing of products already on the market and by Quanta Computer (Taiwan) and Matsushita (Japan) were manufactured. Deviating from the usual meaning of the term they were referred to as OEM products already packaged by the manufacturer in SNI boxes and examined in the context of quality assurance on site (Customer Source Inspection ). A high- end version of the Matsushita notebook was already equipped with a at that time still very rare TFT display.

Minicomputer or multi-user systems

There were systems in the MX series and RM series, Targon, 8860/8862/BNC.

POS Systems

The system developed by Siemens Nixdorf early 1990s and imported POS system Beetle was very successful from the start and was redistributed under the new company name, Wincor Nixdorf and developed. The POS systems are now in many major retail chains in use. For example, Plus, Edeka, Metro, Galeria Kaufhof

PBXs and phones

Siemens Nixdorf System 8818 Digital switching system ISDN ( from 1982): The 1982 featured Nixdorf 8818 DVS was the NCAG the first German manufacturer of a digital switching system, while the 8818 system was the first of the post approved in Germany digital switching system. Between 30 and 3000 phones or terminals could be connected to the 8818. In the composite network, the system 8818 could serve up to 12,000 extensions. The switching capacity for models 80-600 allowed 246 participants, the 3000 model even up to 512 participants, the simultaneous speech, or conference calls with up to six participants. A phone number memory of ten numbers and a quick redial was available to each user. The highlight of the system was achieved with the introduction of software Release 5.1 and 5.2, with the full network capability of the system and the multi- client capability has been introduced. Network capability means that different dislocated installed systems for all participants in functionalities in each plant. All are networked together (up to 255 ) Equipment ( star or mesh shape ) behave transfer from one node to the other as a single physical system with cross-system performance characteristics (for example, recall from one node to another), follow-me, number portability and performance. More and system capability means that in a physical plant several independent or linkable to each other Companies configurations can be programmed.

Octopus E model 300/800 is its fully compatible successor and but also uses the operating system NICOS, the hardware was developed parallel to the Hicom 150H office Com / HiPath 3700, but it is exactly to administer as a 8818, the system is distributed to 2006 been, all pure U P0 and U P0 e terminals (except OpenStage and new ) of the Siemens range and the ISDN system telephones from Nixdorf and all Gigaset Professional handsets can be used on you, the maximum configuration of 800 participants in 1024 connecting points, up to 255 plants are full system-wide networked to a pysikalischen system which is integrated in 8818 large parts. Network modules enable IP telephony system and system networking, call center operations to 1024 agents with standard tools without additional servers feasible.
