Operating instructions

1.
Set the AUTO/MANUAL switch to MANUAL.
2.
Depress the LOAD CARD switch to move the
first card, (assuming no alarms were on).
3.
Depress the RESET ALARM switch.
4. Depress the LOAD CARD switch to read
the
first card into memory.
5. Depress the RESET P switch.
6,
Return the AUTO/MANUAL switch to AUTO.
7. Depress the START
switch to begin auto-
matic feed of the cards underprogram con-
trol.
The following procedure loads data
cardsto aprogram
already in memory. One or two blank cards must be
at the end of the deck,
as requiredby the programmer.
1,
Set the AUTO/MANUAL switch to MANUAL.
2. Depress the LOAD CARD switch to move the
first card.
3. Depress the RESET ALARM switch.
4.
Manually introduce a branch instruction into
the
A register (octal 26XXXXX); put address
of first instruction of program in positions
7 through 19 of the BRU instruction.
5.
Depress the A to I switch (transfers BRU
instruction to the
I register).
6.
Return the AUTO/MANUAL switch to AUTO.
7.
Depress the START switch to transfer con-
trol to the program, which automatically
feeds the rest of the cards,
Maqnetic Tape Input.. With system configurations
having both
a card reader and the magnetic tape
system, it
is a simple matter to read a call card, which
calls
a tapsd program into memory., The entire
program and data input can be on tape, or the pro-
gram can be on cards and the input data on tape.
Without the card reader, instructions must be fed
manually into the central processor to get the pro-
gram started.
Paper Tape Input.
When
a card reader is available,
paper tape programs and data can easily be called
into memory with
a call card. Otherwise, a series
of instructions must be fed manually into the central
processor to get the program started.
ERRORS AND OPERATOR CORRECTIVE
ACTION
The central processor may fail to operate correctly
and cause program halts when the operator neglects
to do any of the following operations.
Operator Checklist
1. Reset alarms before attempting to start.
2. Put SAVE P switch in normal (up) position.
3. Put INSTR/WORD switch in appropriate
position,
Program Recovery or Restart
Watching and interpreting the indicator lights on the
console will tell the operatoi- much about the source
of troubles when a
progranl halts or refuses to start.
The red
alarm lights in the upper left corner of the
console panel are danger signals which indicate that
errors have been
niade, erroneous information has
been received or transinitted, and the program may be
aborted. The CARD
PUNCH and CARD READER
alarm lights
mean the operator must restart or
recover the
program (see following sections). In
some cases, the operator can exercise care and
save the program run. It
is a good general rule
to go into the manual mode of operation before
attempting to correct error situations indicated on
the console.
Whether a
prograill can be saved or is aborted
depends on the answer to the cluestions: has erron-
eous information been received
01- transmitted, or
has information been missed in a read or write
operatiorl? False or missing information will usually
abort a program. By studying the charts on error
and corrective action in the sections on individual
pieces of equipment, the operator will often be able
to determine whether a program can be saved.
When erroneous information
has gotten into a run,
the operator will correct any operator error or have
the service engineer correct any serious machine
errors. The run book should indicate the nearest
programmed recovery point. Successful recovery
will save going back to the beginning of the run.
When
a program is aborted arld no recovery pro-
cedures have been programmed, the operator will
usually have to restart the program at the begin-
ning.
A good operator always looks in the run
hook
or in other operator instructional material
for programmer's instructions.
