"LARGE-SCALE MAINFRAME COMPUTERS

Due to the complexity involved in specifying large main- frame computers and their associated function-oriented architecture for complete systems, these computers have not been charted in this annual. IBM did not desire to submit data as well as some of the other major companies. Companies supplying large-scale mainframe computers and associated equipment usually make a complete analysis and presentation of equipment needs to the prospective customer. Companies to be contacted for large-scale main- frames priced from $100,000 and up are:
Burroughs Corporation
Control Data Corporation
Honeywell Information Systems
IBM
NCR
RCA
Univac
Xerox Data Systems"
