Phil, you are 100% correct. We used some instruction sequence like this to
communicate with the operator:
* ASK OPERATOR WHAT NEXT:
H 111,111 LOAD 1's into A + B Address
ASK BSS MONTHLY,1 START MONTHLY TOTALS IF SENSE-SW=1
BSS DAILY,2 RUN DAILY IF SENSE-SW=2
EOJ H 999,999 LOAD 9's into A + B Address
B EOJ END OF JOB
The Halt ("H") would freeze all flashing lights on the console, the A and B
address lights would display the fake address (1's, 9's) in binary. The
operator
would wake up, realize what happened, look up the operations manual or Job
Setup sheet, flick the requested toggle switches up/down, press the "Start"
button, ...and doze off again.
Now, don't be too hard on Shmuel, he has written a few, somewhat more
useful posts in the past...:-).
