IBM 1BOO Operating Procedures
This publication is a guide for operators using the mM
1800 System console and data processing input/output
devices. It covers in detail operator duties normally
encountered when using the system console or operating
the data processing input/output devices. No specific
programming system is assumed.
Functions of the system console keys, lights, and
switches are included in this publication, as well as
descriptions of the operator keys and lights, manual
controls, setup procedures, and principles of operation
for the data processing input/output devices. Procedures
for clearing conditions that require operator intervention
are given.
Preface
This publication is intended for use as a guide for operators
using the data processing (DP) input/output (I/O) devices
attached to the IBM 1800 System. It is for operators who
have had only a minimum amount of training on stored-
program computer systems. This publication covers in de-
I
tail the usual duties of an operator in conjunction with the
DP I/O devices and the IBM 1800 System.
The practices and techniques given are approved methods
based on the preference of IBM and the practices of many
experienced operators. The user must remember, however,
that the employer has the prerogative of determining the
operator's procedures and responsibilities.
This publication contains a section on the processor-
controller and each DP I/O device. Each section is designed
as a stand-alone unit containing the pertinent operator
information necessary for each device. Pictorial illustrations
are included for their value in clarifying procedures.
