Tm11 Decmagtape System Engineering Drawings

This document serves as the technical documentation package for the TM11 DECmagtape system. It includes:

• Engineering Drawings: A comprehensive set of schematic diagrams detailing the system's logic, signal interfaces, and wiring configurations for the tape control unit and its components (e.g., bus interface, function decoder, tape unit interface, read/write lines, register select, and interrupt control).
• Master Drawing List & Parts Lists: Lists detailing the modules, components, and hardware required for the system assembly.
• Engineering Specification: Detailed functional descriptions, including operation states, register formats (Status and Command registers), and signal definitions for controlling the magnetic tape unit.
• Wire Lists: Extensive documentation for cable routing, pin-to-pin connections, and signal paths to ensure correct installation and maintenance.
• Support Documentation: Accessory lists, revision status, and software list.

The document is designed for the maintenance and engineering of the TM11 tape controller interface with the PDP-11 computer system.
