FP11-A Floating-Point Processor

This manual serves as a comprehensive reference for the FP11-A floating-point processor. Key topics include:

• Introduction: Describes the hardware's purpose in enabling floating-point arithmetic on PDP-11/34A systems.
• Installation and Checkout: Details the installation process for adding the FP11-A module, including current drain calculations and diagnostics (DFKAA, DFKAB, etc.).
• Mathematical Concepts: Reviews floating-point notation, normalization, and arithmetic operations (addition, subtraction, multiplication, division).
• Data Formats: Explains integer (short and long) and floating-point (single and double precision) data representations, including status registers.
• Instruction Set: Provides a complete reference for FP11-A instructions, including mnemonics, operation descriptions, and octal codes.
• Processor Organization: Covers the internal architecture, including the AM2901 microprocessor and microcode control.
• Maintenance: Outlines diagnostic programs (DFFPAA, DFFPBA, DFFPCA) and the use of the KY11-LB programmer's console for debugging.
