Most computers today are used by prepubescents to chatter endlessly and aimlessly and by males to watch porn! We are certainly no further ahead, and arguably have gone backwards!

That "approximately 200 tubes and 2000 crystal diodes" gives a clue to its logic, and "30 binary digits and sign" implies sign-and-magnitude arithmetic. Had twos' complement been invented yet? Of course, $62.5K was a fortune in those days, but IBM wouldn't _sell_ you a computer at any price; you had to lease. Pretty amazing, for 1952.
