Deltamatic SABRE Electronic Reservations activates for "instant" computerized flight reservations.
The initial system consists of about 350 Deltamatic SABRE sets in use by reservations agents at Reservations Control in Atlanta and 24 offices across the U.S., serving customers in nearly 60 cities on the Delta system. Between these "res centers" and two large IBM 7074 computers at Delta's SABRE Center in Atlanta, a "high-speed communications network" processed and stored reservations using two IBM 1401 computer systems, two IBM 7750 communications computers, 23 magnetic tape drives, three magnetic drums and five disk files.
Unlike other airline computerized reservations systems at the time, Deltamatic could handle alphabetic information as well as numeric information, meaning no paper records were required to support Deltamatic at the reservations centers and all records could be processed and stored electronically in the Atlanta SABRE Center. Deltamatic was also faster, performing five times as many functions as any other reservations computer system.
