Agrosystem

It was manufactured from 1984 by JZD AK Slušovice. Hardware is based on U880D @ 2,5MHz.Operating system running on the computer: COBRA/W.

Computer very similar to TNS SC, used with COBRA OS. Usually in a TNS SL64 or TNS A02 cassette (manufactured by Metra Blansko, RO2-220V-200VA-50Hz).

Briefly, Agrosystem can be defined as "a heterogeneous computer system designed for the decentralized management of agricultural enterprises." As the name implies, the main goal was to provide agricultural enterprises with a powerful and at the same time economically viable means of computing for highly decentralized, efficient forms of using computer technology at the enterprise level, event of the race.

Agrosystem was already conceived as a comprehensive computer network, therefore not as an autonomous microcomputer.

The basic principles of the Agrosystem computer network are: connection, mass, distributed intelligence, data aggregation, data collection, data protection; building kit.

The principle of connection is one of the basic and decisive principles. It is realized by technical and logical interconnection of network elements.

Technical means

own line connection inside the company (building area, etc.),
public telephone network,
signal converter (e.g. MDS 1200), telephone device,
automatic telephone dialing module (AVT),
interface module ASAD (for connection between different systems), ASK (for connection between TNS computers),
computer TNS-64 K (concentrator),
ADEC multiplexer (for connecting TNS computers and EC series computers),
UNIPP "off-line" universal data transfer unit (replaces the sensor and punch of the punched tape).

The program resources of the connection are realized by the communication protocol in the program drivers of the TNS computers. The ISO 1745 communication protocol used is implemented under the name BCS-TNS.

Hardware

The core of the system is the basic, innovative assembly of the TNS-64 microcomputer, consisting of modules:

CPU, INT, DRAM 64k, PROM, KBD-TVD, FLP, UVI and ASK.

Software

Currently, system software can be divided into two groups:

COBRA operating system
DELAS + SBASIC operating system

DELAS is a system for developing programs in the language of symbolic addresses (assembler). It includes a text editor, relative assembler, relative loader, and program debugging software. The system media for DELAS are cassettes in KPP 800 drives. The DELAS system allows you to acquire source programs, translate and combine several relative programs into one absolute module. Source, relative and absolute programs can be stored on cartridges.

Use in practice

It was possible to create problem-oriented assemblies from the elements for:

socio-economic calculations
operative management
scientific and technical calculations
management of technological processes

The manufacturer's plan was based on the fact that these spheres will increasingly intertwine until the stage when a complete hierarchically integrated management system of the agricultural enterprise and supra-enterprise spheres will be created.

At the JZD Slušovice, at that time, all areas of the above-mentioned applications were dealt with, in terms of system analysis, development of technical means and software equipment. Examples include the payroll and warehouse agenda, operational management of transport, feeding and herd reproduction, agricultural statistics and direct management of technological processes (fermentation, large-capacity stables).
