NCR Criterion V-8400

The NCR V-8400 is a versatile, general-purpose computer system that offers the medium-scale user all the benefits of virtual storage operation at a readily affordable cost. EmployingNCR Criterion V-8400 much of the same hardware and firmware technology that has already made NCR Criterion 8500 systems the new standard for processing productivity, the V-8400 with virtual storage software opens up potentials for online and multiprogramming applications that are unique for a system of its size. Because of NCR's philosophy of migration path engineering, the V-8450 also protects the user's initial investment against obsolescence by easing his transition to larger or more specialized systems as his requirements change.

The base V-8450 system comprises 384K of MOS memory. Processor cycle time is 112 nanoseconds. Systems are available with a variety of general and specialized terminal and peripheral units for maximum configuration flexibility, and are supported by comprehensive software that includes:

  • The powerful VRX operating system
  • Compilers for most commonly used high-level languages
  • Preprogrammed utility routines
  • An extensive library of tested applications for virtually every type of operating environment.
