• The ancient Library of Alexandria contained approximately 700,000 scrolls, roughly equivalent to 100-125,000 printed books today.
• Apollo Mission: "The LM and CM had identical computers on board, each the size of a shoe box.  Each contained a total storage capacity of 36K of 14-bit words. This means total storage was roughly equal to the 64K bytes of a Commodore-64 computer.  The LM's computer had a "memory cycle time" of 11.7 micro-seconds.  However, virtually all cpu operations required atleast 2 clock cycles making the effective memory cycle time 23.4 micro-seconds, i.e., it effectively ran at only about 43 kHz (0.043 MHz)!"  My Fascinating Interview with Allan Klumpp, the Principal Designer of the LM Computer Descent Guidance Software by Stanley R. Mohler, Jr. Dec '94; The Apollo Flight Journal This article first appeared in Spaceflight magazine, a publication of the British Interplanetary Society, in Vol. 16, No.10, October 1974 (pp. 378-382); M.I.T. - Apollo Guidance Computer; Apollo Operations Handbook, GUIDANCE AND NAVIGATION SYSTEM (G&N), Basic Date: 12 November 1966, URL:
