In addition to being time consuming, this \"clerical\" activity is a frequent source of trivial errors which can invalidate the entire analysis. One approach toward solving this problem is the creation of computer aids that will assist the scientist as he develops a theory or tries to solve a mathematical problem. However, when a scientist is trying to develop a theory he does not only want numbers or graphs that satisfy a particular case. He is most happy when he can derive a general formula that not only describes a large number of cases, but also shows how the various cases are interrelated. The theoretician often starts with a set of postulates or some initial equations and manipulates them symbolically to get resulting equations and conditions. Occasionally the scientist has to develop his own mathematics as he works out a problem by creating new symbols, operators, and functions. A computer system that will aid the scientist in the creative process must be flexible enough to accept these new rules with a minimum of effort on the scientist's part. Our work in developing one experimental system of this nature (Magic Paper 1) will be described and several possible extensions to this program will be suggested.","PeriodicalId":432708,"journal":{"name":"AFIPS '63 (Fall)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124006906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A large capacity cryoelectric memory with cavity sensing","authors":"L. Burns, D. A. Christiansen, R. Gange","doi":"10.1145/1463822.1463833","DOIUrl":"https://doi.org/10.1145/1463822.1463833","url":null,"abstract":"This paper describes a cryoelectric high speed Continuous Sheet Memory (CSM) with 16,384 bit locations and complete cryotron addressing matrices. This memory is of the coincident current, random access type. The entire memory plane is fabricated via vacuum deposition techniques and is contained on a 2 inch by 2 inch substrate. In addition to a planar density of 10,000 bits per square inch, and complete cryotron decoding trees, the memory contains a novel sense structure in the form of a geometrical cavity. In addition to other advantages, the new cavity sense eliminates the major alignment problems. In one type of organization, each substrate or memory plane may be regarded as comprising the nth bit of 16,384 words; all n bits of a word may be read out in a parallel manner. Thus a word length is equal to the number of memory planes. This number of planes is at the discretion of the designer. The continuous sheet memory structure with decoding matrices and cavity sense offers a potential means toward the physical realization of a high speed random access memory of a capacity beyond a billion bits with present day technology. Since all present day computers of general utility are memory limited, the complexity of the mathematical operations performed by these computers is restricted by the size and/or access time of the memory. This restriction is indicative that large capacity high speed memories will play a major role in future computers. Many studies have been made of possible techniques that can be utilized for high speed, large capacity random access memories. These techniques have been in the areas of magnetics, semiconductors, and superconductivity. Microminiature magnetic cores, magnetic metal sheets, and deposited magnetic film show high promise toward the realization of a high speed random access medium capacity memory of about 107 bits, but do not appear to show promise toward large capacity memories of the order of 109 bits. Semiconductors, including transistors and tunnel diodes, also indicate a similar capability toward high speed memories of medium capacity. The present art of transistors is indicative that a very large array of the latter would be costly and cumbersome. Tunnel diodes are two terminal devices and have a relatively complicated memory cell structure. In addition such memories suffer an unavoidable delay due to the high amplification necessary because of signal attenuation; the latter is proportional to the number of words in the memory. A semiconductor device which has been proposed is the cryosar. This device is a two terminal element and awaits future development. In the area of superconductors, film cryotrons and persistors do not appear to offer the potential toward realizing a very large capacity memory of the order of 109 bits. The former has a relatively small bit density and registration difficulties; reasonably high uniformity is required and its relatively large power dissipation in large arrays places an upp","PeriodicalId":432708,"journal":{"name":"AFIPS '63 (Fall)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134106225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its tightly packed elements with closed flux paths of only two to three mils in equivalent diameters are the smallest yet realized by any technique. This smallness is being exploited for high speed. Cycle times as short as 100 nanoseconds have been demonstrated. The smallness of the elements leading to modest drive requirements of only a few tens of milliamperes combined with the inherently low cost \"integrated\" batch fabrication technique opens the possibility of low cost memories of very large capacities: tens or hundreds of millions of bits. A significant cost reduction for the whole memory system is possible because this type of \"integrated\" magnetic structure lends itself particularly well to be integrated with integrated semiconductor driving and sensing circuits.","PeriodicalId":432708,"journal":{"name":"AFIPS '63 (Fall)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128758285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A requirement of nearly all of these systems is the capability to process information. A variety of computing systems have evolved to meet this requirement. Initially the computers were special purpose; that is, designed to solve the data processing problem associated with a specific and, by today's standards, simple system. As the capability of weapons and support systems has grown, the data processing requirements have also increased in scope and complexity, providing an ever-increasing challenge to the computer industry. The trend has been to satisfy these requirements by designing larger, integrated systems around general purpose, stored-program digital computers. This approach has eliminated many of the problems encountered with the use of small special-purpose systems but has created another type of problem---the programming of the general purpose computers. This paper will discuss some aspects of this programming problem, using the Naval Tactical Data System development as a prime example.","PeriodicalId":432708,"journal":{"name":"AFIPS '63 (Fall)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126750543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
