Another ONR document, also courtesy of bitsavers: "A Survey Of Automatic Digital Computers 1953" https://archive.org/details/bitsavers_onrASurveyomputers1953_8778395/mode/2up https://archive.org/details/bitsavers_onrASurveyomputers1953... This document is a list of all the computers in the world at the time, and they are measured by the following metrics: Square feet of floor area, kilowatts of power required, and how many people it takes to operate. I found that because there was a quote in "Turing's Cathedral" by George Dyson: "In March of 1953, there were 53 kilobytes of high-speed random-access memory on planet Earth" We've come a long way from slide rules.
