scheduled for delivery to Griffiss Air Force Base Rome New York in approximately three months UNIVAC The Metropolitan Life Insurance Company began installing Remington Rand's famous UNIVAC electronic data processing system in its home office at I Madison Avenue New York on Thursday April 22 1954 It is the first installation of UNIVAC in the insurance business Decision to install the UNIVAC according to Frederick W Ecker president of Metropolitan Life followed a study over several years by a committee of company officials looking into economies of operation which could be achieved in behalf of the Metropolitan's 37 000 000policyholders in the United States and Canada Suitability of the device to our use is based to a large extent upon the advantages of a large centralized nperation ' Mr Ecker commented O is clearly indicated that equipment of this general type affords the possibility of substantial economies in performing many of our basic home office operations ' The installation will deal with assemblying and analyzing actuarial statistics arising from the millions of transactions affecting the company's policyholders Procedures for the employment of the UNIVAC already have been set up The central computer will be operated on two shifts for five days a week The Metropolitan committee which studied the use of the system is under the chairmanship of Malvin E Davis vice-president and chief actuary Mr Davis also is chairman of the industry-wide Society f Actuaries committee on the application of large scale electronic equipment to life insurance work The installation will handle work which has been done by what were previously considered the most up-to-date mechanized methods Mr Davis commented A great volume of routine work can be eliminated Employees who have been engaged in such work can be released ior other more interesting company nssignments The decision to acquire and install the UNIVAC by the Metropolitan was prompted by such major considerations as 1 The fact that any electronic data processing system should be inherently no accurate that a negligible amount of clerical trouble shooting and control routines would be required TJ e UNIVAC with its parity checks and built-in duplicate arithmetic units assures complete accuracy of results -4 0 2 h fIt' that the UNIVAC is comnpihti'lyV compatibl'e with punched-rard

fact that the invesitment in computer equipment was justified in the expectation of a fairly long-term use and was therefore more properly applicable to equipment such as the UNIVAC which conuld be purchased rather than only rented As the full potential of the UNIVAC Is developed its initial use for actuarial Investigations and reports will be expanded to include such operations as policy settlement work file keeping regular policy services and other office and Administrative functions MIrDAcMiiSAC THE MIDAC University of Michigan Digital Automatic Computer MIDAC Is now in its second year of operation During the six-month period priQr to Tanuary 1954 approximately 780 hours were used by MIDAC f which 70% of the total scheduled time was reoductive In the four-month period from January up to issuance of this report this percentage had risen to 73% In that six-month period 26 major problems were coded formulated or under investiga tion for solution on MIDAC These problems originated fronm Willow Run Research Center the University of Michigan Departments governmental agencies research groups and private Industry In addition over 41 problems have been solved by members of the MIDAC stafi an general utility programs Some of the problems undertaken were a problem in missile simulations optical ray trac ing expansion of the subroutine library solution of a problem in light diffusion de-icing of aircraft racobi Method in obtaining elgenvalues of a matrix numerous problems in data reduction design of a traveling-wave tube amplifier matrix operations and a floating point interpretive routine To date 19 subroutines have been completed and checked out and an additional 18 are In the process of being coded One of the mathematical investigations made was the development of approximations to standard functions using Tchebycheff equal-ripple polynomials Plans are for the computer to generate the approximations The investigation of a proposed method for obtaining all roots of polynomials at once and methods for determining elgenvalues and eigenvectors to extend present methods to the non-symmetrical case were also studied The computational scheme of the MIDAC has been to integrate all standard operating and programming procedures into one automatic system called Michigan Automatic General Integrated Computation MAGIC Several parts of this system have been completed A revised interim Input Translation Program using floating addresses is now in use The revised I T P program provides for coding of instructions and numbers from an external decimal-algebraic language into internal machine binary language This is more expedient than the pure hexadecimal input In the final system translated results and utility programs are to be stored on the magnetic drum instead of on the punched paper tape Eventually the functions performed by the magnetir drum will be accomplished by magnetic tape The input-output system has been improved The original MIDAC system would accept only the sixteen true hexadecimal characters Now the Input -output system is adjusted to handle single-character input and output The original system consisted of only a Flexowriter reader ald priater Two high-speed Ferranti photoelectric readers have now been added -s ° 0 NI'nhmers of the digital computation dveprtmnt have conducted ela•ses and senain trs at

Newsletter are given by the Corporation as follows The computer operates in the fixed point decimal system using binary coded decimals and is decimal in input and output Each word includes 10 decimal digits plus sign This obvintes the necessity of converting from binary to decimal modes and vice versa The four binary digits are operated on in parallel each successive decimal digit is handled serially A powerful set of about 50 commands make up the computer logic The logic is distinguished by the B-register which enables you to modify a command just before execution by the contents of the B-register without changing the command in memory This facilitates iterative procedures by allowing automatic incrementing of addresses during instruction interpretation Our drum memory contains 4080 words including four quick access loops of 20 words each All memory positions are addressable The drum revolves at 3500 rpm giving you an average access time of about 8 5 milliseconds for the 4000 words main memory Access time in the fast loops however is only 85 milliseconds By blocking commands and numbers in groups of 20 to the quick access loops the computer is able to attain an average speed of about 400 operations per second The input-output system includes input from a high speed photoelectric tape reader which can read punched paper tape at a rate of about 560 digits per second Liput may also be from a slower mechanical tape reader attached to the Flexowriter cabinet or from a hand keyboard Output may be to a separate tape perforator perforating at the rate of approximately 12 decimal digits per second or to another mechanical tape perforator attached to the Flexowriter or directly to printed data via the Flexowrlter The Flexowriter has external format controls for tabulation of the data in any form desired or the format may be coded and controlled by the computer Also alpha-numeric output is possible on the Flexo-writer through proper coding The Flexowriter can simultaneously print the output and punch it on paper tape The control panel contains all controls switches and display registers necessary for normal operation and program checking Also a separate display and control panel is available on the computer Through breakpoint switches on the control panel and through coding we may read out data at any desired point in the calculation A library of subroutines including floating point operations and routines developed by our Technical Services Department is made available free of charge to all customers This library is gathered from daily operation of our demonstration computer located here in Pasadena Interchange of routines and subroutines developed among our customers also is encouraged The computer operates from a 220-volt 60-cycle 3-phase outlet The maximum power consumption does not exceed 15 kw The computer operates at normal room temperature a maximum of only 7 kw of heat needs to be dissipated by a building or room air conditioning system Forced air ventilation is incorporated in the computer The computer has been conservatively designed and constructed as to make for high reliability and easy maintenance About 1200 tubes contained in about 160 plug-in units aund3000 diodes are In the computer Space and color-coded wiring is used A built-in test pulse system i used to test plug-in units for marginal operating conditions 7- E w'h block of 20 word i on the tape has its own address to simplify the proble any particulhr block Also an odd-even check is used to check each dec liwal digit tape unit The tape unit does not have to reposition in order to begin search It t ward or backward from Its last read-position depending on the next address to bu The computer will stop for an unantic pated number overflow or for an unallow t combinat n Also an alarm will sound for an error in memory location ABERDEEN PROVING GROUND COMPUTERS The ORDVAC continues to be the most used computer at the Ballistic Research Laboratories Available machine time in excess of 100 hours 32 different problems and 191 problem changes are weekly averages IBM input-output is now an integral part of the Edvac system now be used on either ENIAC EDVAC or ORDVAC The same input data can A total of 18 000 hours of computer time have been used for the solution of problems during the fiscal year ending 30 Sune 1954 This figure represents an increase for the three high speed machines of nearly 1 000 hours over the previous fiscal year and again indicates an iqcrease in the productive output of the Computing Laboratory THE INSTITUTE FOR ADVANCED STUDY ELECTRONIC COMPUTER PROTECT The switching relays associated with the magnetic drum auxiliary memory to the Institute for Advanced Study machine caused considerable operating difficulties with that unit since the last report in the Newsletter Thorough cleaning and inspection of these relays has resulted in very substantial improvement in the operating performance full-scale use The drum is now available for Within the next several weeks it is anticipated that the electrical engineering group will make a modification of the accelerating voltage of the cathode ray tubes which is expected to Improve the read around An auxiliary oscilloscopic graphing device has been designed and is under construction It is anticipated that this will be placed under engineering test within the next quarter Arrangements have been completed to increase the dehumidifying ank' cooling capacities of the air conditioning system for the computer A considerable number of problems have been successfully run during the quarter and reports are now being prepared on them CIRCLE COMPUTER Nuclear Development Associates Inc White Plains New York The acceptance requirement

IWTERNATIONAL TELEMETER CORPORATION The International Telemeter Corporation 2000 Stoner Avenue Los Angeles California has completed and put into operation an automatic nmachine for the individual testing and grading of ferrite cores to be included in computer memory systems This machine is capable of testing cores at the rate of one per second measuring both the signal resulting when the core changes its state of magnetization and the much smaller signal resulting from a flux disturbance inadequate to reverse the magnetization of the core The machine was first used to test the cores intended for incorpo-Ation in the storage matrices of a memory system that Telemeter is building for the RAND Corporrtion of Santa Monica California 250 000 cores were individually tested and sorted into grades in a total time of four and one-half days The yield of usable cores obtained by substituting the grading procedure for 'go no-go tests has provwd to be in excess of 98 per cent of the cores delivered to Telemeter by the manufacturer Telemeter is using the automatic grading machine to produce uniform cores needed in the construction of magnetic-core memory systems being built for the Argonne National Laboratory and for the Ballistic Research Laboratories i t Aberdeen Proving Ground However the capacity of Telemeter's storage -core grading machine is so high that custom grading of storage cores for other users can be arranged - t 10 - t rqtipfI I liviI iz IHi'Vt va tw iiig i h II i hti Ii l' g % '' will 1114 Ittill A 49111111 dl1 IM111nil 4 heivIrAit lAttir mii'na1lrtvivle
