FOREWORD
Operating the Friden Electronic Calculator 130 is like stepping into a new world
of
computing power for the desk calculator user. Through the magic
of
electronics, the
features
of
storage capacity, flexibility, speed, silence, and decimal control are advanced
to
a
level
never before attained.
Designed
to
meet the styling requirements
of
modern business, the Friden 130 is a
pleasant complement
to
any
office
decor.
The complete operating silence
of
this machine
eliminates disturbance
of
office
personnel and promotes efficiency.
This
machine is a solid-state device. These non-moving components are the secret
to
high-speed calculation.
Input
amounts and results
of
operation are visible instantly on
the face
of
a cathode ray tube after the entry or function key is operated. Intermediate
results are automatically retained
in
the upperregisters. Also, an amount or result
may
be
stored for further use
in
a memory unit.
A feather-touch eleven-key keyboard provides the means for numerical input. Function
keys placed adjacent
to
this section are arranged for operator convenience and ease
of
operation.
Accuracy
in
decimal point control is insured by a fixed
point
system, around which all
input
amounts and results are automatically aligned.
No
other programming is nec-
essary. The decimal
point
location can
be
manually selected for
five
different operating
situations according
to
the requirements
of
the work at hand.
The 130 Electronic Calculator is able
to
handle a wide range
of
business and scientific
applications
in
a logical and direct manner. The high
degree
of
flexibility permitted in
approaching problems makes this machine highly adaptable
to
arithmetic calculations
of
great variety.
