It was originally conceived as an interim-computing facility for the use of the government until a more complete computing system could replace it. Consequently, in constructing the machine, it was intended to put into productive operation as soon as possible a minimal machine that could produce computed results. However, the machine proved quite reliable, and the experiments involved in its design were sufficiently successful that SEAC was expanded and kept in operation as a permanent tool at the National Bureau of Standards. It is the purpose of this paper to present some of the operating experience that has been obtained from the use of this computer and to indicate the ways in which component reliability and maintenance procedures have affected the amount of useful computation that has been obtained from SEAC.","PeriodicalId":384732,"journal":{"name":"AIEE-IRE '53 (Eastern)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1953-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132140888","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}

No one quoted carefully-controlled experiments to distinguish among these possibilities, but some opinions favored the last—a relatively long life after an initial period of \"weeding out\" faulty units. The question was then asked whether tests to a given percentage of the initial back current of a diode would indicate more rapid aging for high-resistance diodes than for low ones. Measurements were quoted which indicate that initially-highback resistance units vary faster than those with lower initial back resistance. There was some discussion of the methods of testing diodes for end of life. Since the resistance characteristic is so nonlinear, one speaker made a plea for measuring and talking about voltages and currents rather than resistances. It also was suggested that ac observations should be made, with oscilloscopic observation, since this gives a rapid check of the shape of the characteristic and shows changes of this shape during the observation period. The need was also mentioned for observing intermittent shorts or opens, particularly under vibration or tapping.","PeriodicalId":384732,"journal":{"name":"AIEE-IRE '53 (Eastern)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1953-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127113043","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}

There was considerable discussion regarding standardization of tape. It is impossible at this early date to set any standards, but various issues were submitted for consideration and these are being presented in this report. Everyone interested is invited to write the chairman regarding any of these subjects or any new items which they would like to discuss. After this information has been exchanged and collated, tentative standards will be formulated and distributed for comment. It is understood that although it will be some time before all the machines in the industry can become standardized, the present discussion may be of help to engineers starting new designs because they will be cognizant of the trend at this time.","PeriodicalId":384732,"journal":{"name":"AIEE-IRE '53 (Eastern)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1953-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132509376","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}
