System Modules

This document is a comprehensive product catalog for the Digital Equipment Corporation (DEC) line of System Modules. It details three compatible speed lines: 1000-series (5 megacycles), 4000-series (500 kilocycles/1 megacycle), and 6000-series (10 megacycles). The catalog provides:

• Definitions and Loading Rules: Technical guidelines on standard signals (levels and pulses), logic level definitions (dual-polarity), and loading rules (base load, pulse load, and emitter load) essential for reliable system design.
• Module Catalog: Detailed specifications, logic diagrams, input/output requirements, and power consumption for inverters, diode gates, flip-flops, delays, clocks, pulse generators, pulse amplifiers, and bus drivers.
• Input-Output and Accessories: Information on converters (DEC to IBM, analog-to-digital), power supplies, mounting panels, cabinets, and various installation tools.
• Application Notes: Guidance on integrating modules of different frequencies, wiring techniques (grounding, transmission lines), and maintenance through marginal checking.
