A METHOD OF REPAIRING AND TROUBLE-SHOOTING ELECTRONIC DIGITAL COMPUTERS (METOD NALADKI ETSVM NAKHOZHDENIYA V NIKH NEISLRAVNOSTEI),
Abstract
In connection with the fact that only highly qualified repairmen or operators can more or less quickly find trouble in electronic digital computers and thus reduce the downtimes of the machine, the so-called 'functional cyclograms' are proving to be of great help for the rapid finding of trouble and also for teaching servicing personnel. Functional cyclograms of electrical circuits of the computer units yield in a graphic and concise form sufficiently complete information on the work of a given circuit, functions, and interactions of its elements and are a convenient means of analyzing circuits and are needed when estimating the reliability of circuit operation. The development of functional cyclograms for complex fundamental electrical circuits of the computer units is a rather laborious process, but once it has been compiled the cyclogram makes it possible for unskilled servicing personnel to rapidly analyze a complex circuit. In this article, the authors prescribe the method of functional cyclograms for the specific example of a simplified circuit of a magnetic tape marking unit of the Minsk-2 electronic digital computer. It is shown that in this case the functional cyclogram appreciably facilitates analysis of the work of the computer circuits and finding troubles in it.
