Ultrix Software Family V7M-11

This document introduces the ULTRIX Software Family V7M-11, an enhanced and modified version of Bell Labs' UNIX Time Sharing System, Seventh Edition. It is designed for Digital's memory-managed PDP-11 systems and offers significant advantages for users, particularly in application development.

Key features of V7M-11 include:

• Enhanced functionality: It provides all the standard features of the V7 system, such as the Bourne Shell, Shell Scripts, Pipes, Kernel, C language support, Mail, V7 byte stream file system, a C compiler, Assembler, and UNIX system commands and utilities.
• Invaluable additions: These include a comprehensive error logger and user mode diagnostics, support for bad blocking on large disk systems, the VI screen editor, device driver support for PDP-11 peripherals, and a user overlay kernel scheme for running large programs.
• Multiple versions: The V7M-11 distribution tape or disk offers three versions: a separate instruction and data space version, an overlay kernel version, and preconfigured monitors for loading.
• Digital's single-source support: V7M-11 is a fully warranted and supported Digital product, meaning users get their hardware, operating system, service, and support from a single vendor.

The document also highlights the long-standing relationship between Digital hardware and UNIX software, noting that UNIX was initially developed using Digital hardware and has continued to evolve on PDP-11 family machines.
