HUNOR-131 Electronic Desk Calculator

The HUNOR-131 calculator Is designed primarily for performing

the four basic arithmetical operations, with integers or decimal

num bers as well. The calculator can be used for addition, subtrac­

tion, multiplication, division, repeated addition, subtraction of

several identical numbers (items} or raising to power with integer

exponent (repeated multiplication). The calculator has an arith­

metical capacity of 13 digits. The calcu lator features fully electro­

nic design, it includes no moving parts, and it comprises only

semiconductors as active electronic components. It offers ease

of operation, the numerical and operational keys are arranged

suitably in the keyboard. The machine featu res silent operation,

automatic light and acoustic signalling and by the electronic

interlocking of the keyboard. Facilities are provided fo r clearing

a spu r iously entered digit or the last row of numbers entered

in the calculator, without interfering with the previous results.

If the result of arithmetical operations performed exceeds 13

digits, the overflow is indicated for the operator by an illumi­

nating sign at the end of the in -line digital display and simulta­

neously, 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.

complex operation-sequences can also be performed. The inter­

mediate 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 d igits, 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, t he registe rs are

DIGITAL ELECTRONIC COMPUTER

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 auto­

code, ALGOL and FORTRAN compilers are under development.

Organization and fast operation of the computer facil itate

multiprogramming and also real-time program run indis­

pensable In process control applications.

The program library consists of :

various sub:outines (activation of peripheral equ ipment)

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 con­

tact 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 ques­

tions 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 bu ilt up of silicon semi·

conductors, owing to its modular construction is suitable for a

wide field of applications. Th is means, that accord ing to new

requ irements 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 8,192 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 inter­

face 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 :

Manufactured by EMG

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

a lso be connected to the mach ine, 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 limi ted only by the available channels and

o rganizational aspects.
