NCR Criterion Series

NCR Criterion V-8550

The NCR 8550 has all the processing features, peripherals, and expansion capabilities to be a solution-oriented system for industrial, retail, financial, educational, commercial, medical,NCR Criterion V-8550 and governmental organizations. NCR Criterion is an attractive new alternative, designed to increase operating productivity. Bridging tools for conversion are an inherent part of the Criterion software. These features and a better price/performance ratio, make possible a smooth, economical transition.
Executive software is complete and comprehensive, and complements the design concept of the hardware to be responsive to processing requirements. Operating environments include batch, transaction processing, multiprogramming, and virtual memory management Languages include industry-standard COBOL, FORTRAN, RPG, BASIC, and NCR NEAT/3. The operating systems minimize both programming and operating costs and provide immediate, efficient utilization of the NCR 8550.

Many applications and programs from the NCR Century library, and many programs written by NCR Century users, can be transferred directly to the NCR 8550 without recoding, recompiling, or restructuring files. Initial recompilation may be advantageous for some applications, while other applications may be recompiled at the user's convenience.

The range of terminals available for the NCR 8550 is unparalleled in the information processing industry. General purpose terminals, and special terminals for specific applications, increase the total flexibility of the computer system.
Criterion is a complete information processing system. The NCR 8550 sets the performance standards. It is for the organization that wants greater productivity.
