index Aug67

This document comprises two detailed indices (dated August 3, 1967, and November 7, 1967) listing technical memoranda related to the PDP-X computer project, along with an interoffice memorandum (dated November 8, 1967) explaining the documentation's purpose and distribution.

The indices provide a comprehensive overview of the PDP-X development, covering topics such as:

• System Architecture: Design goals, decisions, specifications, and architecture (including revised versions).
• Components & Peripherals: Detailed specifications for the processor, memory bus, card reader, XY display, Dectape tape format, bus-to-bus adapter, and incremental plotter control.
• Software & Development: Instruction set details, instruction simulator, diagnostic goals, FORTRAN IV specifications, control memory format, and software schedules.
• Project Management: Memorandum distribution lists, progress reports, and marketing suggestions for initial implementations.

The later index (November 7, 1967) is an updated and expanded version, indicating the project's evolution through new entries and explicit notes on revised or obsoleted documents. The interoffice memorandum from H. Burkhardt clarifies that these documents are distributed selectively to relevant departments (Marketing, Programming, Technical Publications, Production) to optimize information flow, minimize duplication, and maintain security, with full sets available to department heads.
