Program Card 8-Punch Interlock
An 8-punch must be placed in the program card, one
column before the start of a programmed skip or
duplication, to provide sufficient time to interlock the
readers. This is required for home-loop operations with
the 1057 /1058 in either the normal or alternate pro-
gram mode. (For line-loop operations, idle characters
must be generated.)
This 8-punch is also required in column 80 of the
program card to permit enough reader-interlock time
for card feeding in the card punch. However, when an
EOB or a card release occurs, no 8-punch is required,
since an automatic interlock occurs for these situations.
Also, when programmed skipping or duplication is in-
itiated in column 1 of the card, the insertion of an
8-punch is unnecessary. The use of this 8-punch means
that the program card function of printing zeros to the
left of the first significant digit is not available for
alternate program.
An EOB generated by the trailing edge of a card in
the 1056 is punched in column 1 of the next card in
the 1057 /1058 (home-loop operation, card reader to
card punch). However, the program card must contain
an 8-punch in column 80. The card containing this
punched EOB is then ejected and the next data trans-
mitted from the 1056 is punched in column one of the
following card (1057 /1058).
Setup Procedures
When the 1057 /1058 is being used with the system,
the setup procedure is:
1. Place the blank cards in the hopper and lower the
star wheels on the program drum.
2. Turn on the main-line switch for the punch (located
on the right leg). Now turn on the main-line switch
for the system (located on the side of the 1051).
When the main-line switch for the system is turned
on an automatic reset for the system occurs. This
causes an automatic eject and 'feed cycle at the card
punch.
Note: For any operations except UNATTENDED, the system
attend-unattend must be set to ATTEND when line control
is on.
3. For system operation, set the following switches:
Auto Feed,
ON.
Print,
ON
(if unit is a 1058 and printing is desired).
Keypunch-Auto, set to
AUTO.
Note: When KEYPUNCH-AUTO is set to AUTO, a buzzer will
sound if any ready status interlock is not satisfied.
Auto Skip, Auto Dup,
ON
(provided this control is
desired).
Stacker Auto Feed,
ON.
4. Press the feed key (on the punch keyboard) twice
to register cards at both the read and punch stations.
5. The program card used in the 1057 /1058 is punched:

Punch Operation - 1057I1058
PTT Code/6 Translation
The 1057 /1058 translates and punches any PTT Code/6
(Perforated Tape and Transmission Code/for 6-Bit en-
vironments) code received. This is under the control of
the function panel and the operator panel special
feature.
Exceptions: DELETE and IDLE codes are not punched, unless the
operator panel special feature is installed; thus permitting the
punching of idle codes.
The 1058 card punch can print:
26 alpha characters, A through Z
10 numerics, 0 through 9
8 special characters
The following codes received by a 1058 from the
1051 may be punched (depending on wiring of function
or operator panel), but are not printed:
EOB
Punch
OFF
Bypass
Restore
Reader Stop
Line Feed
Tab
Punch ON
Record Mark
Carrier Return/
Line Feed
Upper case
Backspace
Lower case
EOT (Home-Loop Only)
Prefix
Minus Zero
Plus Zero
Prefix F, G, and H codes are translated to perform
the following in either home or line-loop operations:
1. Prefix F is duplicate. The field to be duplicated
must be defined by the program card.
