FP11-C Floating-Point Processor

This maintenance manual details the operation, interface, data formats, and logic descriptions for the FP11-C Floating-Point Processor, designed to work with PDP-11/70 and PDP-11/45 systems.

Key sections include: - Introduction & Theory: Explains floating-point number representation, normalization, and the Excess 200 notation used. - Interface: Describes signal definitions and timing for communication between the CPU and the FP11-C. - Data Formats: Covers integer and floating-point data structures and conversions. - Arithmetic Algorithms: Provides technical breakdowns of addition, subtraction, multiplication, and division algorithms implemented in hardware. - Logic Diagrams: Offers a comprehensive analysis of the FP11-C logic modules (FXP, FRM, FRH, FRL groups). - Maintenance: Contains diagnostic procedures, use of the maintenance module, and instructions for debugging using the Microbreak register.
