Held out biggest computer, one that did accounting for Bank of Hong Kong in Luna and also was clearinghouse there. Looked over its instruction manuals and decided was a smart computer for one that could not talk, so asked Mike if he could teach it ballistics? We made temporary link-ups to let two machines get acquainted and Mike reported it could learn simple job we wanted it for—standby for new catapult—although Mike would not care to ride in ship controlled by it; was too matter-of-fact and uncritical. Stupid, really.
