PDP-11/05 Engineering Change Order Log

This document contains a series of Engineering Change Orders (ECOs) and Field Change Orders (FCOs) for the PDP-11/05 processor, spanning from December 1972 to November 1973. The changes cover various hardware and documentation updates, including:

• Hardware Improvements: Cooling optimizations (adding baffles and air slots), electrical transient filtering, mechanical fixes for chassis and connectors, and component part number corrections.
• Documentation Updates: Revisions to wire lists, parts lists, assembly drawings, and the addition of manufacturing prints for variations like the PDP-11/05-NC and -ND.
• Manufacturing Adjustments: Changes to assembly processes, such as switching card guide materials and updating component installation procedures.

Each entry specifies the implementation requirements, including "in-plant" effectivity (phase-in) and "field" effectivity (retrofitting existing machines).
