PDP-11/70 Hardware

This document consists of the student handouts for a PDP-11/70 processor maintenance course. It is organized into 15 days of instruction, covering a wide range of hardware topics including:

• System Overview: Components, physical configuration, and addressing space.
• Processor Architecture: KB11-B block diagrams, timing operations, and control ROM.
• Operational Procedures: Load address, register examine/deposit, and start operations.
• Instruction Set Details: Condition code, branch, single/double operand, and register instructions, including trap and subroutine operations.
• Advanced Features: Cache memory operations, memory management (relocation, protection, and logic), and Unibus map operations.
• Memory Systems: MJ11 core memory operations, configuration, and diagnostics.

The document includes numerous diagrams, flow charts, timing charts, and specific troubleshooting laboratory exercises to support the technical training.
