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, subtraction,
multiplication, division, repeated addition, subtraction of
several identical numbers (items} or raising to power with integer
exponent (repeated multiplication). The calculator has an arithmetical
capacity of 13 digits. The calculator features fully electronic
design, it incl udes 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 features silent operation,
with an electronic rate.
The reliability of calculation is ensured by electronically controlled
automatic light and acoustic signalling and by the electronic
interlocking of the keyboard. Facilities are provided for clearing
a spuriously 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 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.
HUNOR-157 Multi-keyboard Electronic Calculator
The HUNOR-157 Multi-keyboard Electronic Calculator can be
used to advantage to perform a great variety of operations. The
