ADDITIONAL FEATURES AND REMARKS Manufacturer Outstanding features include high speed, compatibility with IBM 704 and 709 systems, a rich operation code set, and a very fast memory. Unique system advantages include overlap of input output operations with computing with very low memory interference rate and automatic interrupting facilities permitting I/0 devices to interrupt main program. Many special features and attachments are available on a "Request for Price Quotation" basis: (i.e.) Cathode Ray Tube pictorial output, clocks, extended precision arithmetic, direct data I/0 device, tape switch, etc. Manufacturer's recommendations for the care and handling of magnetic tape: Storage for frequent or infrequent usage (Mylar Base) at relative humidity 0 to 80% (The upper limit on humidity is given to prevent the formation of fungus and mold growth. This limit may be exceeded by hermetically sealing the tape in a plastic bag.) and temperature 40 to 120oF. The tape should be stored in a dust proof container. Should the tape be exposed to atmospheric conditions outside the above limits for more than four hours, it must be reconditioned by allowing it to remain at the given condition for a length of time equal to the time it was away. Twenty-four hours reconditioning is necessary if the tape is removed for longer than twenty-four hours. General Precautions The tape should not come in contact with magnetic material at any time and should never be subjected to strong magnetic fields. Either of these can cause the loss of information or the introduction of noise. When shipping magnetic tape, the reel should be placed in a dust-proof container and hermetically sealed in a plastic bag. Additional support should be obtained by enclosing in an individual cardboard box. GE Outstanding features include column binary, on line clock, speed necessary to meet schedules, capacity large enough to handle our largest programs, and size (not cumbersome machine to operate). Customer asks for tapes to be assigned to him although physical use of tapes are under control of tape librarian. The customer maintains a log of what he has been assigned and releases the tapes as data is no longer of any value. Stored in special design plastic containers under humidity and temperature controlled conditions. Smithsonian Institution The Smithsonian Institution will use an IBM 7090 System at its Astrophysical Observatory for four hours during the day. The rest of the time is to be made available, by contract, to Computer Services, Inc. of Englewood, New Jersey, for purchase and resale.

ADDITIONAL FEATURES AND REMARKS The IBM Card-programmed Electronic Calculator solves problems involving any number of sequential steps to obtain a single solution. It is a combination of several units, including three standard IBM machines, and bas many applications in engineering, scientific and actuarial computations. One standard unit is an electronic calculator capable of 2,174 additions and subtractions or 86 multiplications and divisions a second. Other units include an accounting machine for interpreting instructions and for accumulating and printing results, a storage unit for retaining data for later use in a problem and a punching unit for recording results in IBM cards. Numerical instructions in IBM cards direct the sequence of operations. These instructions tell the electronic calculator where to obtain factors; whether to add, subtract, multiply or divide, and what to do with the result-print it, punch it, hold it for later use, or perform combinations of these possibilities. When not being used for this type of computation, the accounting machine and electronic calculator may be disconnected and used to perform standard accounting and computing operations.

Since the periods between 7 a.m. and 10 a.m. together with certain irregular periods, such as Saturdays and Sundays,
BRL 1961, ILLIAC, start page 0563
are devoted to a heterogeneous group of engineering, maintenance and laboratory functions, it is more instructive for an error standpoint to look at the periods between 10 a.m. and 7 a.m. of the next day in order to make an observation of the error frequency in the machine. This is the actual period when the machine is designated for use, although certain engineering procedures frequently require the scheduling of extra maintenance time. With this in mind a summary table has been prepared, using the period between 10 a.m. and 7 a.m. of the next day. This table lists the running time when the machine was operating, the amount of time devoted to routine engineering, the amount of time devoted to repairs because of breakdowns, and the number of failures while the machine was listed as running. During the 5:30 - 6:30 period (when the machine is checked, if no errors are to be found, the time is given to the "running column". Each failure was considered to have terminated a running period and was followed by a repair period in preparing this table. Since the leapfrog code is our most significant machine test, the length of time which it has been used on the machine is listed separately together with the number of errors associated with that particular code. This information for the month is presented in Table II. It is important to notice that, except during scheduled engineering periods, any interruption of machine time that was not planned is considered a failure in this table. In rare cases, where the failure is not known until a later time, it is possible that no repair period is associated with the failure. This overall system has been adopted because it makes it possible for a machine user to estimate directly the probability that the machine will be "running" any instant of time and the probability of a failure during any given interval of running time. The following table presents a typical summary of errors or interruptions for June 1959: Source of Error Quantity of Errors Control 2 Arithmetic 1 Memory 3 Drum 13 Reader 3 Punch 3 Unknown 7 Input-Output 1 Run-over from Sched.

A. R. :11 Leapfrog 16:18 Library Development 3:04 ------ 146:52 ADDITIONAL FEATURES AND REMARKS New ILLIAC Codes During the month of September two new routines were added to the ILLIAC Auxiliary Library. Aux. P21-268 Data Plotter Output Converter II. Under the control of parameters this routine will convert a data tape output by the standard ILLIAC printing routines into a tape suitable for input to the data plotter. Aux. X15-269 Maximum Speed Sexadecimal Input Preparation for Magnetic Drum and/or Williams Memory. This routine permits loading of the drum and/or Williams memory from the reader at maximum speed. Any information previously assembled on the drum or in the Williams memory is punched out in sexa-decimal form in such a manner that the tape (provided with its own bootstrap) can be read in and sum checked at some later time. ILLIAC Usage During the month of September specifications were presented for 17 new specifications. This list does not indicate how the ILLIAC was used because large amounts of machine time may have been consumed by problems with numbers less than 1488T. Numbers followed by T axe for theses. 1488 T Sociology. Patterns of Inmate Response. The problem is to group questions (55) in terms of common differentiation of 556 subjects. What are some of the common patterns of responses? Which questions can be grouped together? A pattern analysis is used (KSL 294 in which the usual order of persons and responses is reversed. 1489 T Sociology. Subject Similarities. The problem is to group inmates in terms of how they answer questions about prison life and themselves. A pattern analysis is used in the standard way on each of two subsamples of 50 subjects. Two subsamples are used: 1. To investigate the reliability of the patterns obtained. 2. To compare samples from two different prisons on differences and similarities in patterns of response. 1490 Civil Engineering. Thermal Stresses in Elastic Shells. This is to solve the problem of an elastic shell subject to the transient tempera- ture input associated with high velocity motion through an atmosphere of variable density, although any temperature history input could be used. Two kinds ofthin shells are being studied; spherical dome shells and conical shells. The significance of this analysis lies in the possibility of treating shells under either applied loads or temperature variations by one unified approach.
BRL 1961, ILLIAC, start page 0569
The method of solution is a finite difference approach, applied successively as time is increased incrementally. 1491 T Economics. Analysis of the Demand for Coffee. The problem consists of estimating price and income elasticities of the demand for coffee in the United States. Yearly data on the coffee demand, prices, stocks, and imports to the United States will be used. For the estimation of the demand equation a limited estimate will be used. No other than standard library routines are involved. 1492 Mechanical Engineering. Nozzle Design for 4" x 4" Blow Down Tunnel. It is intended to design a pair of nozzle blocks for the blow down tunnel in Aerodynamics Laboratory B. The supersonic nozzle profile will be first calculated by the method of characteristics and then corrected for the bound- ary layer growth along the nozzle. The complicated step-by-step calculations and iterations can easily be handled by ILLIAC. The fundamental net calculation has been developed under Problem No. 866 and the general boundary layer calculation has also been developed under Problem No. 1189. It is hoped to adapt and modify the codes from Problem Numbers 866 and 1189 so that the final nozzle profile for a certain supersonic test Mach number can be produced. 1493 Botany - Eastern Illinois University. Analysisof Tree Growth. This is a continuation of an earlier problem, Problem No. 1267, in which daily tree growth measurements are analyzed using the standard program, K 16. The best fitting equa- tion forpredicting daily growth is being obtained by attempting multiple correlation using different combinations of factors on different species of trees and for different periods of the season. Part of this newly submitted data are measurements of growth occurring before leaf enlargement during 1958 and 1959, a period which differs markedly from the later growing season. Part of the data are yearly growth ring measurements from 1901-1951. These are to be analyzed in terms of values ascertained from monthly weather bureau records. This second approach using yearly rather than daily growth measurements was conceived because of an evident influence of the previous season upon the growth of trees. It is hoped that by combining an analysis of daily growth during a given year with an analysis of seasonal growth during a number of years it will be possible to evaluate both the immediate and long-range effects of our weather upon tree growth. 1494 Psychology. Situation-Response Analysis of Anxiety Behavior. This study differs from other studies of anxiety, even though it is based on an inventory, because both situations and responses are specified in the structure of the inventory. Four groups of subjects, a total of 348, were presented with thedescription of some situation and asked to say whether and to what degree he would show each of a sample of emotional responses. The K-8 routine is to be used to compute Product Moment Correlations, Means and Standard Deviations for each of the responses for the four groups. A factor analysis for each of the groups is to be computed using KSL-1.90 on the Correlation Matrices. 1495 Animal Science. Potassium Requirement for Baby Pigs. This research is intended to ascertain the amount of potassium required for optimal growth by thebaby pig. The mathematical method is the method of least squares. 1496 T Veterinary Medicine and Physiology. Strontium and Calcium Metabolism. The replacement of calcium in the diet of young pigs by strontium is being compared to controls receiving calcium, negative controls receiving neither calcium nor strontium, and pigs receiving both ions. ILLIAC is being used to analyze the variance between the treatment groups for the various criterions used, i.e. weight gain, bone calcium, bone strontium, etc. 1497 Agricultural Economics. A Game Theoretic Model for Cattle Feeding. The feeder cattle enter- prise is viewed as a game against nature with natures choices assumed to be restricted to the price-cost situations generated in the last ten years. The farmer's choices consist of six differ- ent feeding systems (or linear combinations of these). Four different situations are considered; 1. Payoff matrix in terms of returns per $100 feed fed. a. Maximize the minimum return. b. Minimize the maximum loss or "regret". 2. Payoff matrix in terms of returns per animal. a. Maximize the minimum return. b. Minimize the maximum loss or "regret": Thisproblem may be set up as a linear programming problem with straightforward use of the library routine M15-183.
