Joliet Arsenal, Comptroller, E.A.M. Systems Branch
Located at Joliet
Arsenal, Joliet, Illinois, the system is used for civilian payroll, civilian
personnel statistics, stock accounting, cost accounting, and procurement
accounting.

PROGRAMMING AND NUMERICAL SYSTEM
Internal number system Biquinary, decimal, and alphabetic
Decimal digits/word Variable from 1 to 10 digits plus sign
Digits/instruction Not internally programmed
Arithmetic system Fixed point, variable
Instruction type Three address
Number range Variable

ARITHMETIC UNIT
The timing is synchronous.
The operation is sequential.
One full cycle on the computer requires 400 milliseconds. 75 milliseconds
are required for feeding, sensing, and punching the card. 325 remain for
calculation. If the calculation requires more than 325 milliseconds, the
computer automatically waits until the end of calculation signal has been
given before punching, feeding and sensing the next card. Buffing is not
used.
The purpose of the electronic computing unit is:
To connect card columns for sensing, punching, and reproducing.
To set constant values.
To set the machine for the operations to be performed and the sequence
of the operations.
To perform all calculations with an electronic accumulator.
To store the values calculated.
To check each arithmetic step.
To visibly read all elements of all arithmetic steps. The arithmetic
unit uses floating point but storage uses a selected fixed point.
The biquinary code is as follows:
Digits Biquinary Code
0 0
1 1,0
2 2
4 4,2
5 1, 4
6 6
7 1,6
8 8
9 1,8
Alphabetic characters are wired to become two or three numeric
characters at the input level. For example, an A becomes 111, a C becomes
99. See Storage.
Negative numbers are carried as the tens complement of the number. A
negative sign indicates that the value is negative instead of positive.
The location of the decimal point is variable and may be arbitrarily
assigned
to .each input and storage location.
There is only one arithmetic register, called the accumulator. It has a
capacity of 22 digits. The computation of each program step takes place
within the accumulator. For example, an addition would be performed as
follows:
1) Clear the accumulator
2) Eater the first value according to its decimal location.
3) Enter the decimal location of the second value.
4) Shift the first value to align with the decimal of the second value.
5) Enter the second value, performing the process of addition.
6) Enter the decimal location of the result storage and shift the result to
align with it.
7 Place the result in the result storage.
8) Subtract value two from the result.
9) Subtract value one from the result of 8).
10) Check to be certain that the accumulator is zero.
Each step is balanced to zero before the computer continues to the next step.
The four possible steps and the method used to check each are:
Step Proof
Value 1 + Value 2 = Result Result - Value 2 - Value 1 = 0
Value 1 - Value 2 = Result Result + Value 2 - Value 1 = 0
Value 1 x Value 2 = Result Result/Value 2 - Value 1 = 0
Value l/Value 2 = Result Result x Value 2 - Value 1 = 0
The computer will not continue unless the step checks to zero.
The computer has automatic decimal alignment. Programs have been
developed which use a floating point method, although the computer is
operating with automatic alignment.
Scaling may be accomplished by multiplying or dividing the number by a
factor, or changing the decimal location by a selector.
An overflow stops the computer.
The remainder is dropped off in the final result, although it is used
during the proof of the step.
The round-off of sums, differences, products and quotients depends on
the decimal location of the result storage. The accumulator unit has 22
positions, as follows:
M Sections
1 2 3 4 5 6 7 8 9 10 11
A Sections
11 to 9 8 7 6 5 4 3 2 1

All results are placed in storage from positions 10-1 of the A Section. Each
storage is assigned a decimal location for the program involved. A location

BRL 1961, UNIVAC 60, start page 0887

of 4/3 would mean that three places are to be retained in the result
following the decimal. If the result of any step-addition, subtraction,
multiplication, or division contains more places than those allowed in the
result storage, the additional digits will be located in the M Section,
beginning in column 11. When the result is placed in the storage unit, they
are thereby rounded off. Rounding off requires an addition step.

Comparisons are made by two subtraction steps.
Each step has two branchings, plus and minus. Zero
is always considered plus. The first step of the
two value 1 minus value 2. If the result is minus,
value 2 is greater than value 1. If the result is
plus, value 1 is equal to or greater than value 2.
The second step would be value 2 minus value 1. If
the result is minus, value 1 is greater than value 2.
If the result is plus, value 1 and value 2 are equal.

Control Unit

The computer has no stored program.
The input-output panel indicates the card fields to be sensed, punched
and reproduced. The constant program panel indicates the program to be
followed, step by step, and the constant value which will be used.
The computer operates on a three address system. Each program step, which
is externally wired, contains the following six instructions,
in the following form:
V1 Pr V2 = R - BR + BR
V1 The storage, constant, or card-read field to be used as value 1.
Pr The process (+, -, x, /)
V2 The storage, constant, or card-read field to be used as value 2.
R The storage into which the result is to be placed.
-BR The next step or operational function to be
performed if the sign of the result is minus
+BR The next step or operational function to be
performed if the sign of the result is plus.

Breakpoint stops may be included in the program. At the plus or minus
branching of any step an instruc tion requiring a division of 0 by 0 or a
number by 0 may be given. Both of these steps cause the computer to stop, and a
corresponding light is lit.

The electronic computing unit contains a control panel with a dial. Each
step may be dialed in turn. For each step value 1, value 2, the result, the
process, the branching, all decimal locations and whether the step checks
may be read from the panel.

The computer will stop under the following conditions:
1) Empty feeding magazine.
2) Full receiving magazine or chip pan.
3) Sensing of alpha.
4) Zero divided by zero.
5) Number divided by zero.
6) Incorrect voltage.
7) Temperature too high.
8) Overflow condition on a step.
9) Failure to check.

STORAGE
Medium Words Digits
Vacuum tube 6 60
The storage system used is biquinary. Each column
of storage contains 5 tubes, representing the digits
1, 3, 5, 7, and 9. There is no tube for zero, which
is represented by the fact that none of the tubes
are lit. An odd digit is represented by the corres-
ponding tube 1, 3, 5, 7, or 9. An even digit is
represented by the odd digit which is immediately
lower in value, plus the 9. Therefore, a 2 is 1 plus 9, a 4 is 3 plus 9, a
6 is 5 plus 9 and an 8 is 7 plus 9.
The word length in storage is ten digits (columns) plus sign.
Alphabetic characters require five columns of storage for two characters,
three columns for a single character. A single word can therefore contain 4
columns of alphabetic characters as opposed to 10 columns of numeric
characters.
Storage is actually part of the computing unit. There is no buffing unit.

INPUT
Medium
Card Sensing-Punching Unit
The purpose of the Card Sensing-Punching unit is to sense and punch
tabulating cards and to indicate and control general machine operation.
A maximum of 36 words (card read fields) may be used in one program. Up to
60 digits may be divided as necessary among 36 words. The sign of each
field is in addition to the 60 digits.
A 90 column punched card code is used. This is the same biquinary code as
is used in the storage unit. All 36 words are sensed simultaneously on one
cycle. Five columns are required to sense two columns of alphabetic
information; three columns are required to sense one column of alphabetic
information.

This machine has only one card input/output device,
therefore, the input and output cards are the same
or must be interfiled prior to computing. The ma-
chine normally operates at the 150 cards/min speed,
but does not have a post sensing station for verifi-
cation. Two passes of the cards are required for
verification.

Site preparation: Installation of 220-volt power junction box,
acoustical tile (ceiling of EDP room only) and ventilating hood
for the Univac 120. The building is of reinforced concrete
construction with the EDP unit located in the basement.
The Univac 120 may be adjusted at the time of installation to
operate from 208, 220, or 230 volts, alternating current,
providing the regulation of the power source can be held to plus
or minus 5,% of any of the above voltages. This voltage must be
measured at the junction of the power supply line and computer
power line, and under normal line load conditions. In the event
the regulation is not within the 5%,, plus or minus, a voltage
regulator is necessary.
The air conditioner is included in the Electronic

Computing Unit of the Univac 120 to assist in maintaining
that unit at the most desirable operating temperature.
The air conditioner consists of four 15 inch fans in the base
located above air filters. These fans operate at 1750 rpm to
force air through the inside of the unit.

The heat dissipation is approximately 400 BTU/min. The air
flow through the machine to affect cooling
is 2500 cubic feet per minute.

ADDITIONAL FEATURES AND REMARKS
Manufacturer

The Univac 60 and Univac 120 Systems are similar, except with
regard to such items as storage capacity, price, rental rate, and
service costs.

BRL 1961, UNIVAC 120, start page 0896

Bureau of Reclamation
The Univac 120 automatically checks each arithmetical step of each
calculation before proceeding to the next step. Forty program steps of the
Univac 120 may be used in any numerical sequence desired. Furthermore, one
program step or series of steps can be reused or repeated as often as required in
any calculation. Sperry Rand machines require more careful programming. There
are dividends to this, though, in that often through more careful programming
we can realize much greater efficiency.
As far as commercial applications are concerned,
we find the size of a Univac 120 to be almost ideal.
It is not so large as to lure us into over-program-
ming an application; nor is it so small that we have
to make repeated runs. Rather it seems to break our
computations into sizes which can be effectively and
economically handled.
Dugway P. G.
Outstanding features include low cost with punched
card versatility. Although the present computer
system was adequate for its original purpose, the
problems being generated at Dugway are of such a
nature that a plugboard programmed computer does not
conveniently lend itself to their solution.
AiResearch
Outstanding features include internal checking of
all computations, branching on each step, address
instructions, and ample selectors give great versa-
tility.

FUTURE PLANS
Bureau of Reclamation
Feasibility studies are being conducted in
many areas of our Project Office to determine the applications that are necessary
for the EDP unit to be of greater value in reporting to management. With these
factors in mind, the equipment requirements could conceivably change.
However, additional equipment is not contemplated in the near future.

Dugway P. G.
A local Data Processing Committee is currently studying proposals
received from approximately 12 vendors with the view that a small stored
program computer would provide Dugway with the programming flexibility
that is required in statistical and mathematical research operations. A stored
program computer will allow us to solve problems that are not economically
feasible with our current system.

AiResearch
Our present system is over 4 years
old and has been expanded to the limit of punched cards. To further advance
our system, we now have on order two (2) Sperry Rand Univac Solid State Tape
Computers (one 80 Col., one 90 Col.) with 5 tape servos each. These are
scheduled for delivery in September and November 1960. Initially we are
considering these computers as a natural expansion to our present punched card
system. As soon as our present system (modified to take advantage of the
computers capabilities and magnetic tape) is "on the air", we will start to
integrate our runs into a more sophisticated system, but keeping the shock of a
new system to a minim.

APPLICATIONS
UNIVAC 490 System is essentially a communicationscomputer network which
provides instantaneous inventory and production control data to companies
and government agencies having widely scattered offices, plants and
warehouses. Hundreds of transmitting and receiving devices strategically
located throughout the country can communicate directly with the central
processor. As a result, the computer can receive real-time data from a transaction
source, process the raw data and deliver the necessary answers in ample time to
complete the original transaction. A wide variety of input and output devices
are available to meet specialized requirements.

PROGRAMMING AND NUMERICAL SYSTEM

Internal number system Binary
Binary digits/word 36
Binary digits/instruction 36
Instructions per word 1
Instructions decoded Model 1103 41
Model 7103A 50
Arithmetic system Fixed and floating point
Instruction type Two address
Number range Fixed point (1-2³⁵) <= n <= (2³⁵-1)

Floating point -2¹²⁷ <= n <= 2¹²⁷

The instruction consists of a 2-character operating code
(command), a 5-character First Address and a 5-character'
Second Address. The floating point system utilizes nine
instructions. Fixed point operation utilizes 41 instructions.
There are two 15 bit addresses per word. This facilities writing of
programs, since less instructions are required, less storage is
consumed in storing
program, and a smaller repertoire of instructions has to be
learned by the programmer.

Operation times given above are average values. Add time
includes transmitting result to V address. Multiply time is for
product to form in accumulator with multiplier in "0" register.
Divide time includes quotient in "0" register and positive
remainder in the accumulator. The arithmetic unit is constructed
of Eccles-Jordan flip-flop type circuits triggered by pulses from
pentode "gate" circuits which are "enabled" by either other flip
flops or signals from "AND" or "OR" circuits. The flip flops may
be manually controlled from the console. Although the arithmetic
mode is parallel, all operations pass through the exchange register
"X". The "X", "0", and "A" registers separately and in
combination are used to form eleven distinct logical and arithmetic
sequences.

Operation tends toward closed shop.
Operators after a 90 day indoctrination assignment elsewhere within the
division are assigned to the computer with a combination of on-the-job and a
six week course taught periodically by our own personnel. Programmers are
normally hired as professional mathematicians with strong physics background
and are assigned initially in other sections of the organization to familiarize
themselves with the mathematical and physical problems which they are
concerned with. At the conclusion of approximately 1 year assignment in this
area programmer trainees are selected and after attending a six week training
course either taught in house or at the manufacturer's plant are given on-the-job
assignments. Six months to a year are required to provde proficient programmers
for our operation after selection and assignment to the computing laboratory.
Training of technicians and engineers is a responsibility of the manufacturer
and are provided by him.
Programmer training in this activity is more concerned with teaching new
employees the techniques and approaches used in solution of range
instrumentation problems. This is more difficult than teaching the art of
programming of computers. The period prior to assignment to computers is
used to screen out prospective programmers who do not have what our
management considers to be desirable qualities and traits for this particular
type of operation.

Most difficulties account for the difference between good time and attempted
to run time were caused by mechanical malfunction of Uniservos. Until very
recently it was necessary to write programs utilizing all available Uniservos
and a malfunction of any one would result in an attempt to ran resulting in
failure. Recently the number of Uniservos have been increased to 10 which will
tend to eliminate this source of difficulty.

ADDITIONAL FEATURES AND REMARKS
WSMR IRM
The water cooled design of this equipment virtually eliminates difficulties
associated with refrigeration and air conditioning. As a matter of actual fact the
computer room is cooler than is maintained in most offices.
Magnetic tapes are stored in wall cabinets within the computer room. The
number required is small as compared with most installations of this type.
Normal building conditioning provides adequate protection from humidity
temperature, etc. Security against loss of operating ability due to fire is
accomplished by providing duplicate tapes to other installations under this
command such that in case 1 tape is damaged it could be replaced within a matter
of an hour or two and by duplicate programming of problems on other machines
in the neighborhood, such as the IBM 704 located at DRD-N and the IBM 704
Computer operated by the Flight Simulation Laboratory at WSMR. For the
particular applications involved at WSMR loss of data tapes is not as critical as
the loss of programming tapes. No special care is taken to insure against loss of
data tapes.
Integrated Range Mission of White Sands Missile Range operates two
computing facilities. The 1103A reported in this questionnaire and an IBM 704
Computer physically located at Holloman Air Force Base are reported on
separately. Both computers are used for the same type of activity, namely the
conversion of raw range flight test measurements to engineering forms of data. It
is anticipated that about January 1962 it will become necessary to replace the
existing 1103A Computer with a solid state computer having much greater
internal speed and greater capacity. Machines of the CDC 1604, IBM 7090,
Philco 2000, etc. type are being considered. A feasibility study is under way to
ascertain whether at that time it will be feasible to replace the 704 Computer at
Holloman with a high speed data link and utilize the one high speed computing
facility in place of the two now in operation.
It is planned to replace the card-to-tape converter, the tape-to-card converter,
and the high speed printer with a USS 80 Computer. In so doing the overall
operation will be speeded up, economy in floor space will be achieved, and an
increase computing capacity will be provided while at the same time the cost of
operation will be reduced.
Eglin AFB Additional equipment can be connected by controlled
bits on a selector board (colloquially designated OR board).
NASA Lewis
Simultaneous input, output, and computing on problems. Concurrent
operation on two separate problems, each with its own input, output, and
computer.
The machine, its peripheral equipment and its programming aids are
tailored to do data reduction in the most efficient manner, with the lowest
level programmers possible.
Lockheed
A library system for reserved tapes is maintained. No particular protection
for tapes due to durability of metal tapes. Fireproof storage media is currently
undergoing evaluation.
The 1103AF system is composed of the following components: 2 Univac
Scientific 1103AF Computers each with floating point, variable block, 8,192
words of core storage and 16,384 words of drum storage. There are two
Remington Rand 600 lines/min printers,

and one Remington Rand Card-to-Tape Converter.
Johns Hopkins ORO Outstanding features are considerable memory
capacity, high internal operating speed, and great versatility in transferring
information to and from external equipment.
U of Minn
Electronic Associates DATALINK provides 6 channels of conversion from
analog to digital (13 bits/word) and 4 channels of conversion from digital to
analog. The DATALINK connects the 1103 with a REAC (Reeves Electronic
Analog Computer) containing two computer cabinets (20 amplifiers in each)
and a cabinet of four servos.
The ll03 has been modified to include two special instructions for work
with polynomials, an instruction for transmission of a word from the left half
of the accumulator, and an interrupt feature to increase system efficiency
when external equipment is used.

FUTURE PLANS
Holloman AFB An output platform is being designed which allows an
automatic recording, i.e. without computer control, of all real-time computer
outputs and a digital and analog display of real-time computer outputs.
W-P AFB The 1103A will be phased out by June 1961 due to the
installation of the IBM 7090 in November 1960.
NASA Lewis Additional tape handlers, floating-point arithmetic
hardware, high-speed line printer, compiler, and high-speed plotting are
planned.
Lockheed LMSD is in the process of converting all 1103AF work to
IBM 7090 and CDC 1604 Systems. Both 1103AF's will be released.

APPLICATIONS
Manufacturer
System is used for both scientific and commercial
applications, for example, satellite tracking and
trajectory calculations, linear programming, logictic scheduling, inventory
control, and census.

The Univac 1105 Computing System is a synchronous, large scale, high
speed, general purpose, automatic data processing computing system. Programs
of internally stored instructions, capable of self-modification, determine the
sequence of operations. Internal storage is afforded by directly addressable
magnetic cores and drums. The system is designed to use magnetic tape,
punched cards, punched paper tape, electric typewriter, analog-to-digital and
digital-toanalog converters, visual displays, plotters and real
time instrumentation as input-output.

U. S. Air Force, Dayton AF Depot Located at Dayton Air Force
Depot, Wilmington Pike, Dayton, Ohio, the system is used for the
following fields of application:

Stock Control and Distribution - Inventory Management
Method of controlling and distributing material by Air Material Command
Supply Depots and AMA's to Air Force activities, maintenance contractors and
other military services world-wide. The system provides a data processing
technique which enables Aims to administer a timely, accurate and effective
supply logistics system. It provides item accounting, including inventory
position and various products for effective management of serviceable, reparable
and excess material. By-products which are the basis for dollar accounting and
Air Force assets management, inputs for requirements computation and other
stock control purposes are provided.

Management and Control of Due-In-Assets
Recording of assets due in from contractual procurement, Department of Defense
excesses or other Air Force activities. The depot having responsibility for a
commodity class or specified weapons system utilizes this data system to
administer a more timely and effective logistical support system. Item account

ing providing due-in status data for utilization in material
distribution, requirements computation and buying programs,
are included in this system.
Requirements Computation - Replacement Type Items
The purpose of this application is to design, develop, and
implement a data flow and data processing system by which
various types of replacement item data products, required at
appropriate AMA/AFD, Hq AMC, and higher headquarters
management levels may be periodically computed on an AF
world-wide basis. The system as designed is to be capable of
promptly reacting to changes in the many elements which affect
AF requirements for items (e-g., program changes, authorization
changes support policy changes, funding limitations, etc.) is also
to be compatible with the latest data handling and processing
technological improvements. The system as presently
implemented is designed to provide the following major types of
replacement item requirements and related management data
summarized by weapons/support system, funds program/project;
program group, mission code, property class, AMA/AFD, or total
AMC, as appropriate for the products involved. Data now output
from the system are: time-phased projections of "gross" and
"net" item requirements; procurement program and budget
estimates item and/or dollar summaries of the above; contract
termination and retention/disposal level
data; consolidated asset and item information data summary
products; item-dollar inventory segmentation and requirements
support effectiveness data; end weapon and support systems.
Product Performance Analysis Airborne Armament and
Electronic Items

The following applications are scheduled to be production runs in the near
future.

IM/FSC Cataloging, Standardization and File Maintenanc This project is to
develop a system which will establish, maintain and distribute Federal Catalog
and re-

lated data applicable to all inventory manager items, including, but not limited
to, the following: Federal, Catalog, EAM Detail and Trailor Cards, Stock Control
Data Cards, Packaging and Transportation Data Cards, Interchangeability
Record Cards, and Family Group Publication EAM Cards. The system will
provide for the: initiation and distribution of stock list change, initiate suspense
and follow-up on request for Federal stock number, notification of stock number
assignment to Air Force contractors; publication of stock control data sections;
cross-reference sections; transportation and packaging data sections;
interchangeability and substitution data sections and possibly the
identification section of AF stock list. Initially, the ADP systems utilizing
outputs from this project for the updating of catalog data are restricted to:
Inventory Manager Stock Control and Distribution Management and control of
Due-in Assets, maintenance operating stock support; requirements computation
for consumption-type items. Weapons systems control and distribution; and
base support class stock control and distribution.

Master Material Support Record
This project will develop procedures to establish and maintain a master
material Support Record that will provide a complete source-coded range of parts
and materials with replacement rates required for all levels of repair support. This
record will be developed from initial provisioning source-coded documents and
up-dated based upon engineering changes, source code changes, stock list
changes, changes to replacement factors derived from improved methods of
computation, and changes to specialized repair activity material standards and
contractual material requirement lists. The record will serve as a basis for initial
SRA material standards and contractual MRL's and provide a means whereby the
Inventory Manager can analyze these documents and establish an acceptable
relationship between SRA and contractor material projections and the Master
Material Support Record. This project will furnish source data for computation of
the Buyers Guide for operations and maintenance parts and material.
Manpower Management (Personnel and Labor Accounting)
This project involves a recording of employee skills, abilities, education,
training, experience and test scores as a basis for selecting out of five (5) best
qualified personnel for a given position vacancy.

BRL 1961, UNIVAC 1105, start page 0921

Normally, this process will occur within a single depot, but for
certain categories the entire command will serve as the selection
base. Related products, required periodically, would be Reduction
in Force Registers, data on skills losses (turn-over), skillsusage
trends, and on inventory of skills levels as a basis for determining
proper station assignment of new missions or functions.
Automation of Item Schedules for Procurement Docu-
ments
This project visualizes optional automation of the PR
coordination cycle as a continuous flow from generation of a
requirements to the subsequent automatic preparation of
IFB/RFP schedules. Areas to be incorporated within the project
include: the automatic grouping of items for procurement
purposes, automatic initiation of funds, standardization of
procurement data, precoordination of PR's, and automatic
preparation of item schedules.
Civilian Personnel and Labor Accounting
The objective of this project is to permit machine
preparation of the following in lieu of the present manual
systems:
SF 50's Personnel Action; periodic pay increases;
notification of automatic actions, i.e., age, retirement, service
awards, detail expirations, annual per

formance evaluations; Unit Manning Document; all statistical
reports; automatic print-out to indicate any condition reflected by
statistics, requiring administrative action, i.e., sick leave, turnover,
tardiness, unused annual leave, grade levels, jobshortage categories,
etc.; classification survey schedules; rosters of all persons who
have received training by s cific courses and rosters of all training
received tall. courses) by
