VAX Computer Systems

This document introduces the Digital VAX family of computer systems, emphasizing its core philosophy of complete hardware and software compatibility across a wide range of models. It explains how the VAX architecture allows businesses to scale from desk-level MicroVAX systems to large-scale VAX 8600 configurations and VAXclusters, all while maintaining a consistent VMS operating environment, Digital Command Language (DCL), and 32-bit instruction set. The text details key components such as VAXclusters for data integrity and high availability, Digital Network Architecture (DNA/DECNET) for connectivity, and Digital Storage Architecture for managing vast amounts of information. The guide also covers configuration options, support services, and the transition of applications between systems without requiring costly rewrites.
