Peripherals Handbook 1981-82

This document is the "Peripherals Handbook 1981-82" by Digital Equipment Corporation (DIGITAL), offering a comprehensive guide to their UNIBUS PDP-11 and VAX peripheral devices. Published in 1981, it details various hardware categories including disk drives (e.g., RX211, RL01/02, RK07, RM02/03, RM05, RM80, RP06, RP07), magnetic tape systems (e.g., TU58, TS11, TE16, TU77, TU78), lineprinters (LXY11/21, LP11 Series), card readers (CR11 Series, CMS11-K/CME11-K), and sensor I/O devices (e.g., digital-to-analog converters, analog-to-digital converters, general-purpose interfaces, and real-time clocks).

Each peripheral is presented with its features, general description, data organization, operational procedures, interrupt handling, reliability/maintainability, and detailed specifications. The handbook also includes comparative charts for easier selection and dedicated sections for register diagrams, bit definitions, ASCII and Hollerith code charts, and UNIBUS I/O addresses and vector assignments. It targets customers across diverse applications, from scientific research and industrial control to commercial data processing and education. Notable additions highlighted include the RP07 disk drive with Winchester technology and the TU78 magnetic tape transport with Group Coded Recording (GCR).
