The KY11-J Programmer's Console is the front panel for the KD11-B CPU used in the PDP-11/05 and PDP-11/10.
It allows a programmer to display and deposit data in main memory, and start, halt and single-step the CPU.
Displays and controls
The 'Address/Data' indicator array display memory addresses and data. The 'Run' light indicates that the CPU is executing instructions.
The 'Switch Register' is used to enter both addresses and data. The 'Load Addr' (Address), 'Exam' (Examine), 'Start', and 'Dep' (Deposit) switches perform the named function. If the CPU is halted, toggling the 'Continue' switch does a variety of things, depending on the position the 'Enable/Halt' switch is in. In the Enable position, the CPU continues operating; in the Halt position, it performs a single instruction.
Implementation
Front panel operations are implemented by microcode in the CPU. (See Section 5.5.3 in Part 2 of the PDP-11/05 computer manual, below, for details.)
