Principles of Operation

Chapter 3 of the PDP-8/E technical documentation provides a detailed look at the processor's principles of operation. It covers:

• System Overview: A breakdown of the eight functional areas and the OMNIBUS architecture that facilitates communication between modules.
• Timing: Describes the timing generator (M8330) and its role in managing time states and memory cycles.
• Memory: Details the MM8-E memory system, including core storage and driver/sense modules.
• Processor Logic: Explains the register control (M8310) and major register (M8300) operations.
• Other Components: Briefly covers the power supply (H724), Teletype control (M8650), programmer's console (KC8-EA), RFI shielding (M849), and available options.
• Signal Finder: Provides a reference table (Table 3-1) for basic system signals to aid in logic analysis.
