It's odd that such an article would even exist in 1953, as digital computers were in their infancy. I have an IRE (now IEEE) magazine from 1953 devoted to describing nearly every computer in existence at that time. They were all different. The only computers that had more than one copy made were the IBM 701 and the Univac. The National Bureau of Standards made SEAC and SWAC, Standards East and Standards West Automatic Computers, were similar but not identical, being built by two different groups to a common software definition.
