KB11-A Timing and Miscellaneous Control

This document, titled 'Engineering Change Order Log', provides a detailed list of eight specific engineering change orders (FCOs) for the M8105 module used in the PDP-11/45 system. Each entry includes the FCO number, the relevant code, revision levels, a description of the problem, the required physical or logical correction (such as etch cuts or jumper additions), and implementation details regarding whether the changes apply to in-plant manufacturing, existing field installations, or both. The document serves as a maintenance and upgrade reference for ensuring proper timing and control functions within the PDP-11/45 processor.
