Programmer's Console Manual

The KY11-A Programmer's Console is a crucial interface for the PDP-11/20 system, allowing for manual control of system operations. This manual outlines the functionality and logic behind the console, including:

• Console Operations: Detailed explanations for functions like LOAD ADDR (address input), EXAM (examine memory location), DEP (deposit data), CONT (program continuation), HALT (stop processor), and START (initialize system).
• Logic Implementation: Describes the console's physical implementation via a circuit board in the KA11 Processor, focusing on lamp-driver and switch-filtering logic.
• Power-Fail Handling: Provides documentation on how the system manages power interruptions, including the trap sequence to address 000024, power-down subroutines, and power-up restoration procedures.
• Technical Reference: Contains console flow diagrams, timing waveforms, and specific references to the KA11 Processor and PDP-11/20 System manuals.
