The greatest individual assistance was rendered by WAC Staff Sergeant Violet J. Confer. An
undertaking as comprehensive as this national survey, requires that a large quantity of data be acquired,
correlated, transcribed and checked. Particular attention must be paid to accuracy and detail. We are
heavily indebted to Staff Sergeant Confer for the major role she has performed in all phases of
preparation of this report. She has been responsible for the general conduct of the survey, the control of
communications with respondents, the preparation of correspondence, screening returns, sorting returns,
preparing the layout of all pages, and doing all the art work, typing, titles, and photo arrangements.

INTRODUCTION
PURPOSE OF THE SURVEY REPORT
Before any major decision can be made regarding the acquisition, installation, operation, improvement or
retirement of computing equipment, first hand technical information must be obtained concerning the characteristics,
availability, cost, operational problems, capability and useful life of available systems. Efficient management
requires that the experience of others be exploited wherever such exploitation is beneficial. The present trend in the
rapidly changing computing and data processing hardware field is toward. higher operational speeds, increased memory
capacity and reliability, and solid state electrical components, including a widespread use of semi-conductors and the
advent of the use of thin magnetic films in standard commercial systems. However, only existing or readily available
equipment may be utilized for the immediate solution of scientific and commercial data processing problems.
Many persons in the computing and data processing field continually y seek answers to many different
questions simultaneously. Some of these questions are: Can present methods, practices and procedures
used in a given organization be accomplished by automatic computing and data processing equipment?
Will investment in such equipment reduce costs, provide improved service, conserve manpower or save
time? When shall existing computing equipment be modified, supplemented or replaced? Of all available
equipment, what type of system is best suited for the solution of a given problem or a given group of
problems? Is the maximum possible return being obtained from a given investment in computing equipment?
Does a given problem require specially built equipment or is a solution to be found with
comercially available standard equipment? Should computing equipment be rented or purchased? Should a
system be installed "on the premises" or should computer time be purchased elsewhere? The purpose of
a surveillance and evaluation program is to provide answers to these and similar questions.
Government agencies, particularly Department of Defense agencies, and their contractors, require the latest
technical information concerning computing and data processing equipment in order to properly establish their policy
regarding acquisition, installation, operation, improvement and retirement of equipment. The purpose, therefore, of
this survey report is to allow government agencies and their contractors to benefit from the results of the computing
system surveillance and evaluation program conducted by the Ballistic Research Laboratories.
In 1955, a survey of electronic digital computing systems was conducted by the Ballistic Research Laboratories
in order to provide technical data for the evaluation of the then existing computing machine complement of the
Laboratories. The results of that survey were made available in BRL Report Number 971, M. Weik "A Survey of Domestic
Electronic Digital Computing Systems". The report was well received by persons in government and industry. The U. S.
Department of Commerce undertook further printing and distribution of the report under cover of Public Bulletin
111996, Office of Technical Services.
A new survey of electronic digital computing systems was conducted during October, November and December 1956
and January 1957 by the Computing Laboratory of the Ballistic Research laboratories. The new survey was conducted as
part of the continuous surveillance and evaluation program of the Laboratory. The results were published as BEL
Report Number 1010, June 1957. This report covered the results of the new survey and superseded EEL Report 971. The
U. S. Department of Commerce undertook further printing and distribution of this report also under cover of Public
Bulletin 1119968, Office of Technical Services.
Due to the great interest which has developed in these survey reports, the Department of Defense has co-ordinated
this activity among the Armed Services. This report contains the results of a third survey of domestic electronic digital computing systems.

SCOPE OF THE SURVEY REPORT
This report is limited to commercially available and existing operational electronic digital
computing and data processing systems manufactured or operated within the United States. Large, inter-
mediate and small scale systems are included, regardless of whether the determination of "scale" is
based on size, weight, cost, storage capacity or any reasonable criterion. An attempt has been made
to include both general purpose and special purpose equipment. It must be borne in mind that there is
no clear-cut line of demarcation between systems designated as special purpose computing machines and
certain "on-line" control applications, in which a computer is used to determine operational control-
commands, based upon data received by the system from instruments measuring the results of the commands.
These systems usually have analog input and output with internal digital computation and transformation
of information to and from digital form.
Among the items not covered by this report are analog computing systems, foreign systems or separate
computing system components, such as analog-digital converters, separate storage units, arithmetic units,
input-output units, and data recording units, except when these are associated with specific complete
systems. Many recording media converters, such as magnetic tape-to-card converters, card-to-paper tape
converters, etc., are not specifically covered, except again as they are used with specific complete
systems. By a "complete system" is meant an electronic digital computing system with input, output,
control, arithmetic and/or logical and storage units.
PROCESSING OF THE SURVEY DATA
A consolidated system description was prepared from data made available by the user and the manu-
facturer. Information concerning each computing system was divided into the following sub-headings:
Applications
Programming and Numerical System
Arithmetic Unit
Storage
Input
output
Circuit Elements of Entire System
Checking Features
Power, Space, Weight and Site Preparation
Production Record
Cost, Price and Rental Rates
Personnel Requirements
Reliability,Operating Experience and Time Availability
Additional Features and Remarks
Future Plans
Installations
The large volume of technical data processed for this report will make errors unavoidable, particu-
larly in correlating and transcribing information. It will be appreciated if errors are brought to the
attention of the Ballistic Research Laboratories. Statements, claims and criticisms were screened as
much as possible. Every endeavor was made to insure that the information included in this report is
factual. To a large extent certain superlative adjectives used in describing equipment, were deliber-
ately eliminated as a matter of fairness and in order to avoid implication in sales activities.

The interpretation of the data included in this report is perhaps the most difficult aspect of
all, therefore much of this activity is left to the reader. In Chapter II, the data are grouped under
alphabetically sequenced computing systems descriptions. The charts and tables in Chapter III have
been prepared in order to. show various relative characteristics, features and trends. A brief analysis
and interpretation of the -data accompanies these tables. It must be emphasized again that data concern
ing computing systems taken out of context or disassociated from other related data, can be misleading.
Because of this, the information contained in this report, particularly the tabular data of Chapter III,
must be used with appropriate caution.
It is recommended that the prepared tables in Chapter III be used only as generalizations to show
trends. Data on specific systems should be taken from the systems descriptions rather than from the
prepared tables. Further details must be obtained from manufacturers or users directly. This report
does not constitute an indorsement of any of the products described within it.
USE OF THE SURVEY REPORT
As has been previously stated, the computing field is a dynamic and rapidly changing one. From a
technological point of view, some of the information contained in this report is obsolete. Certain
computing systems may be considered obsolete when they are installed. However, in most cases, manufact
urers are accepting orders and will continue to produce, the systems described in this report for quite
a number of years. Chapter II contains engineering and programming descriptions of 222 different types
of computing systems. Persons who are interested in the acquisition of systems will find useful infor
mation on applications, cost, personnel requirements, and power and space requirements for specific
systems. Operators may find useful suggestions on modifications and improvements. The question of
reliability, a particularly difficult one to resolve, has been answered to some extent under the sub
heading: Reliability, Operating Experience and Time Availability. Under each sub-heading, the source
of information is given. When a source is not stated, the manufacturer is the source of data.
A List of References and a revised Glossary are given in Chapters IV and V.
It is hoped that enough general and specific technical data have been compiled in the following
four chapters to permit anyone involved in the computing and data processing field to draw at least
some general conclusions and find answers to the questions which may be occupying his mind at the
present time.
