EMG-830 Digital Electronic Computer
The EMG-830 digital electronic computer though according to
its technical construction belongs to the category of II. generation
machines, in its logical structure features many Ill. generation
characteristics.
These characteristics facilitate the application of the machine
for data processln1, technical-scientific c~lculations and
process control. Continuous development of the program
library Widens the applicatiOn facilities even after putting tO
operation.
Programming is facilitated by SIMPLE assembler and EMG autocode,
ALGOL and FORTRAN compilers are under development.
Organization and fast operation of the computer facilitate
multiprogramming and also real-time program run indispensable
In process control applications.
The program library consists of:
various sub:outines (activation of peripheral equipment)
standard functions
floating point and double word length operations diagnostic test
programs
technical and data processing programs
compilers and Interpretive programs for the above programming
languages.
Application of the computer is greatly helped by the direct contact
of EMG Computer Sales Department which is always readily
at customers' disposal.
To make customers acquinted with the machine, EMG organizes I
courses for programmers and operators on different levels.
EMG Computer Sales Department helps customers In all questions
concerning operation and installation (e.g. experts advise
EMCi 830
the user on computer room layout and on adequate enviromental
conditions).
The up-to-date electronic computer built up of silicon semi·
conductors, owing to its modular construction is suitable for a
wide field of applications. Th is means, that according to new
requirements the performance of the computer might be In·
creased by simply plugging-In additional modules (without
changing the original machine construction). If, for instance,
the problems at the very begining might be solved by a small
configuration consisting of only a few modules, the possible
later extension should be taken account only from the aspect
of space requirements.
The EMG-830 us a single address machine. Wordlength is 2~
bits In case of a data processing variation and 21 +3 bits in case
of process control variation. In the latter case the separated 3
bits serve for parity check which ensures increased safety of
operation indispensable in process control applications.
The instruction format ensures direct addressing of 32,768 store
locations in case of data processing and 8,1 92 store locations in
case of a process control variation. In other words, the ferrite
care store can be extended with ~K modules up to 32K capacity
in case of a data processing variation and up to 8K in case of a
process control variation.
For the storage of wired programs the Internal store might be
extended with 256 word permanent store modules. Cycle time
of the operative (f!!rrite core) store is 6 !J.S, average speed of the
machine is 25,000 operations per second.
