A Survey of Eniac Operations and Problems 1946-1952

This report summarizes the entire operating history of the Eniac since February 1946, when the machine was demonstrated to the public as the first large scale general purpose electronic digital computing machine. It brings up to date much of the material presented in the unpublished paper entitled The Eniac - A Five Year Operating Survey presented at the Detroit meeting of the Association for Computing Machinery on 27 March 1951. The primary interest of the paper is the brief descriptions given of the specific unclassified problems completed during this period. It is hoped that individuals not yet in immediate contact with high speed computers will gain some insight into the type of problems which machines make accessible to computation. Pertinent reference material is given to a variety of unclassified published material related to these completed programs.
