Initial selection and screening of the CFA candidate computer architectures

The initial selection criteria that were developed and used by the Army/Navy Computer Family Architecture (CFA) committee in their evaluation of alternative computer architectures is presented in this article. These initial criteria were used in this first phase of the CFA evaluation process to reduce the number of computer architectures from the original set of nine to the most promising three or four architectures for the more intensive evaluation discussed in the companion articles. The machines selected by this Initial ranking and screening process for further evaluation were the Interdata 8/32, DEC PDP-11, and the IBM S/370.
