The LSI-11: A System Microcomputer

This document describes the design criteria, technical specifications, and features of the LSI-11 microcomputer system. The LSI-11 is designed to provide minicomputer performance at microcomputer pricing, utilizing N-channel silicon gate MOS technology and a microprogrammed architecture to emulate the PDP-11 instruction set. Key components include the processor module (KD11F), Data Chip, Control Chip, and Microcode ROMs (MICROMs). The document covers the system bus (LSI-11 BUS) structure, memory and peripheral interface options, and configuration flexibility for small and large systems.
