Introduction to DECsystem-10 Software

This document serves as an introductory guide to the DECsystem-10 computing environment. It covers the three major components of the system: the hardware, the operating system (monitor), and the non-resident software (languages, utilities, and applications). It describes the multimode computing capabilities, including timesharing, Multiprogram Batch, and real-time processing. Additionally, it details system features like spooling, the mass storage file system, inter-process communication, and remote communications. The document concludes with an appendix surveying the hardware configurations available in the DECsystem-10 family.
