If the result of arithmetical operations performed exceeds 13
digits, the overflow is indicated for the operator by an illuminating
sign at the end of the in -line digital display and si multaneously,
by an acoustic signal.
The field of application can be widened considerably by using
the external keyboards (max. 6), permitting the calculator to
be controlled in a t ime sequence from several places as well.
A numerical printer can also be connected to the calculator,
printing-out automatically on a paper strip the numbers and
operational si&ns appearing on the digital display panel of the
calculator.
HUNOR-157 calculator can be connected with type HUNOR-158
external keyboards each having a built-in display. Not only one,
but max. -4 such un its can be connected to the machine. This way,
the machine HUNOR-157 -1 58 performs in a sequence the task
of four separate calculators. The layout of the machine meets
all requirements of up-to-date working areas. The calculating,
controlling parts as well as the registers are accommodated
in the central unit (HUNOR-157}. The elegant design keyboards
having a built-in display (HU NOR-158) can be coupled to this
central unit. The central unit can be placed at a suitable spot of
the office, while the small-size keyboards are placed on the desks.
The calculator is designed primarily to perform the four basic
arithmetical operations (addition, subtraction, multiplication,
division). Repeated additio n, subtraction, multiplication (raising
to powers), division can also be made. By using its free registers,
complex operation-sequences can also be performed. The intermediate
results of calculations are stored by the machine and are
directly applicable as the first operand of a following operatio n.
The capacity of calculatio n is 15 decimal digits, this is sufficient
even in the most specific fields of application.
The HUNOR-157-158 offers ease of operation, arrangement of
the numerical and operational keys is advantageous. Operation
is silent and is performed at an electronic rate. The calculator
is fully electronic, containing no moving parts. The active elements
of the calculating unit are all semiconductors, the registers are
built-up of ferrite memo ry cores.

The reliability of calculation is ensured by electronically controlled
automatic light and acoustic signalling and by the electronic
interlocking of the keyboard. During the calculation significant
digits will not be lost. The number of decimals of the result can
be determined by adjustment of the 16-position decimal-dial
located on the keyboard unit.
The calculator contains three universal registers for forming
and storage of constants, subtotals and the sum of products or
quotients with correct sign and decimal point.
To the HUNOR.-157 calculator a printer (HUNOR-159) can
also be connected. The prin'ter can be placed at a suitable spot
of the office and can be Interconnected with the central unit by
means of a cable. It prints out the operations performed depending
upon the position of the switch located on the operating keyboard.
The calculator HUNOR-157-158 can be used to advantage to
perform engineering design, business management, statistical
calculations as well as d iverse other applications.

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.

6-4 input or output peripherals can be connected to the machine
each having an identical internal standard interface unit. Several
backing stores e.g. maanetic tape, magnetic disc, etc. can be
connected to the machine.
Selection of the applied peripheral equipment always depends
upon the particular needs of the customer. The necessary interface
units are always supplied by EMG.
Standard peripheral selection includes the following e.g .:
FS 1500 tape reader
PE 1501 FACIT tape punch
IBM 731 on-line typewriter
BULL S-41 200 llnesfminute line printer
BULL 557 600 lines/ minute line printer
Back ina s~ores :
PEN 5 D SPERAC IBM compatible magnetic tape memory
MD 17 SPERAC magnetic disc (capacity approx. 58 million bits)
MS 300 SA GEM magnetic disc (capacity: 2, 4 or 8 million bits)
For a special request, any peripheral equipment, data link or
satellite computer (compatible with the EMG machine) might
also be connected to the machine, EMG providing the necessary
interface units.
The computer ha.s 64 input-output peripheral interface channels,
further equipment might be connected by inserting multiplex
units.
There Is no restriction for the maximum number of one type
of peripherals it is limited only by the available channels and
o rganizational aspects.
