Auxiliary Equipment - IBM 709 General Information Manual

Auxiliary Equipment
Auxiliary equipment, a part of most data processing
systems, is described below.
1. Card-la-Tape (Figure 63)
The
IBM
714 Card Reader,
IBM
727 or 729 I Magnetic
Tape Unit, and the
IBM
759 Card Reader Control per-
form independent card-to-tape operations. Informa-
tion can be read from a punched card and written
on magnetic tape for future processing in the com-
puter at a speed of 250 cards per minute. Auxiliary
card-to-tape equipment does the following:
a. It converts punched card data into magnetic
tape records without using the computer.
b. It selects or rearranges the data on cards for re-
cording.
c. It emits constant information.
d. It checks each record automatically after it is
recorded.
e. It selects data from two cards, if desired, to be
combined into one record on tape.
2. Tape-la-Card (Figure 64)
The
IBM
722 Card Punch,
IBM
727 or 729 I Magnetic
Tape Unit, and the
IBM
758 Card Punch Control per-
form independent tape-to-card operations. Informa-
=
tion can be read directly from magnetic tape and
punched into cards. The tape can he recorded either
on card-to-tape equipment or on one of the
IBM
data
processing systems. Tape to card equipment per-
forms the following operations:
a. It converts magnetic tape records to punched
cards independent of computer operations.
h. It automatically checks punched data for accu-
racy.
c. It operates the card punch at a speed of 100
cards per minute.
3. Tape-la-Printer (Figure 65)
The
IBM
717 Printer,
IBM
727 or 729 I Magnetic Tape
Unit and the
IBM
757 Printer Control perform inde-
pendent tape-to-printer operations. Information, can
he read from tape and printed in the exact form in
which it appears on tape. The tape can be recorded
either on card-to-tape equipment or on one of the
IBM
data processing systems. The equipment performs
the following:
a. It converts magnetic tape records to printed
forms without depending on computer opera-
tions.
b. It prints 150 lines per minute, using 120 type
wheels of 48 characters each. Alphabetic, nu-
merical, and II special symbols are used.
c. It checks printed information automatically.
