IV. CONTROL CONSOLE
The control console (Figure 13) serves both operator and maintenance functions. The control
exercised by the console is not normally used during normal program execution. Control from
the console is concerned with initially loading the program into memory, starting the execution
thereof, monitoring the progress of the program, and program debugging.
The switches and lights and their more important functions are:
1.
The contents of the A, B, C and P registers may be modified directly from the control
console.
2.
The contents of memory may be displayed in the M-register. The P-counter is used
to specify the memory location to be displayed.
3.
The P-counter is automatically incremented so that sequential locations in memory
may be displayed by depressing the SINGLE CYCLE button.
4.
The contents of memory may be modified by the 18 INSERT SWITCHES.
5.
The automatic loading of a program may be initiated from the control console (hard-
ware load).
