NDR small computer

from Wikipedia, the free encyclopedia

The NDR-Klein-Computer ( NKC for short ) was a do -it- yourself project for a computer , which has been accompanied by the television program ComputerTreff of Bavarian TV since 1984 . The name refers to both the size and the developer of the computer, Rolf-Dieter Klein .

In 1984 NDR school television, under the direction of Joachim Arendt, brought out a 26-part television series entitled NDR-Klein-Computer , each lasting 15 minutes. This program, which was moderated by Thomas Naumann , was not only about showing the viewer how a computer works, but also introducing a modular system with which the technically interested layperson was able to use the simplest examples from the Broadcast to the high-quality home computer to complete his practical exercises. The idea for this modular system came from Rolf-Dieter Klein, who was an author at the computer magazine mc at the time.

He accompanied the television series, which he also moderated, with a series of articles. He also brought out several books on the NDR small computer. The Franzis Verlag brought the television series as a video cassette out and the magazine mc published several special issues on specific topics on this computer system. The system was sold by Graf Elektroniksysteme in Kempten and the electronics store Detmold. The Fischertechnik company delivered a robot kit, which was one of the most vivid applications of the NDR small computer. The largest microcomputer education project of its time had started.

The modularity of the NKC was its greatest strength. Its hardware spectrum ranged from a simple 8-bit single-board computer based on the Z80 A, with which simple control tasks could be carried out through to CP / M software, to a 32-bit system with a 68020 CPU. The software spectrum of this system ranged from bits and bytes in EPROMs to the CP / M operating system and the programs and programming languages ​​that could run on it. Even MS-DOS found its way to the NKC with the help of an 8088 CPU card. Some systems are still in operation, but with PS / 2 keyboards, 3½ "floppy, IDE hard drives and modern memories. In the meantime, new cards have been developed by users to replace the special components of that time. which provides a new graphics card (with VGA connection), a serial interface, a sound card as well as a PC keyboard and mouse connection. There is a new basic program for the 68xxx system, which also supports the IDE interface for booting.

In the course of 2017 and 2018, the original boards of the NDR Klein Computer were redesigned and improved in detail by committed users. The new layouts were then manufactured in China, which means that the NKC system is now available to a large group of new users again.
