PC Applications and networks with PCs

The development of computer technology has caused the demand for computer linkage to rise, with the emphasis less on the transfer of data than on joint usage of large amounts of data. The most common computer networks today are still the LANs (Local Areaobotron was represented at thehis tine with the new LAN EC-NET. It is constructed fromomponents and is used exclusivelyink to the personal computerhe program package EC-NET with tho operating system0 serves the worldwide NETBIOS interface. It includes such functions as sending, receiving, and storing data and offers diskettes, dictionaries, and printers for joint usage in tho LAN. Access to the network is via programs such as dBase III Plus and ARIADNE, via computer languages suchASCAL, and via DCP commands such as DIR and COPY.

In addition, Robotron presented new applications for the SCON-LAN. Alongside programs for literature research and joint databank usage, it demonstrated linkage with digital radio link technology. The digital radio link devices0 are used in order to transmit data over long distances and difficult terrain features. They can link individual remote SCOM-LAN users as well as several LANs. The distance between two radio link stations can be as much asm. ransmission path containshannelsransmission speed of up tobits per second.

The network software is compatible with the Novell Advancedr the Novell System Fault Tolerant. It contains functions such as controlled access to joint data, systems for directory backups and file identification tables, parallel treatment of magnetic disks, as well as continuous checks and error messages. Linkage with the Bthernet network of the VTnd1 can be achieved using gateway data transmission.

In addition, and without interfering with these services, it permits the processing of, for example, routine office tasks.


--Microprocessor circuits The microprocessors theBit system after0 produced by the collective combine Mlkroelektronik Erfur. Its proposedomponents will make it possible toew generation of personal computers and control systems (for example. The four new types (sic) of this system first shown at the spring trade fair are the central processing unit (CPU), the bus controller, the DRAM controller, and the error detection and correction (EDO circuit.

Surface mountoblo devices (SMDs) are becoming more widespread internationally because they occupy less space. Mlkroeloktronik Erfurt has responded to this trend withit one-chip, as well ae theKbit4 and the windowless 32 Kbit 2 as SMDS.

--ASICs Parallel to traditional devices in SMD design, the space requirement of entire circuits can be reduced much more affectively by using application-specific integrated circuitshich in turn can be SMDs. The Carl Zeiss jena collective combine has been offering two different ASIC typosear, the CMOS Gate Array0 and the standard cellularSOO/20 0 differs from0 only in the number of wiringhe Gate Arrays on prefabricated silicon dices require that the number and position of the functional elements and chip surfaces and pin numbers be constant, ln return for which they can ba obtained more quickly and at less cost.

This is to ensure simple management through an easily surveyed programenu-driven selection of program parts, error determination,OESY will be steadily developed and improved and adapted to new technology. It is offered foritS with the SCP operating system,0 with thend0 PCs and4 with DCP; in the absenceard disk, work can be accelerated with the supportAM disk.

Robotron also demonstrated possible applications of the4 in Arabic and Chinese text editing. The AL-BAYAN system with the DCP operating system allows Latin and Arabic characters to be edited, manipulated, configured, and printed within one text. In the arabic editing mode the individual characters are written on the screen from right to left, as is customary. Either English or Arabic can be chosen to drive the menu. The ALBAYAN system also has numerous functions for comprehensive text manipulation and configuration.

with the Chi-Easy system, Chinese characters can be input to the PCs using the operating system MS-DOS. In order to input the desiredpecially coded character pattern is usedeading pin is passed over the character as in normal writing.aximumtrokes is necessary forharacters contained in the character set, because after each newf the most common characters containing those strokes are displayed, selected and written on the screen. In SS percent of the cases, the desired character is found after the second stroke. The texts can also be outputrinter.
