Unit. This manual

is

divided into

five

major sections.

• Introduction

• Console Indicators, Switches and Keys

Describes the console indicators, switches, and keys.

Only information required by the operator

is

con-

tained in this section.

• Printer-Keyboard

Describes the mechanical features

of

the PR-KB and

contains information required by the operator for

normal PR-KB operation and maintenance.

• Operating Procedures

Describes general operation, system initialization and

error procedures required by the operator for normal

system operation.

• Features

Provides reference information on the integrated

file

adapter and available emulators.

This manual is intended

INTRODUCTION

This

is

a graphic

operating

procedures

manual.

It

contains

only

information

necessary

to

operate

the

System/370

Model

145

Processing

Unit

and

integrated devices.

Order

number

for

manuals

containing

operating

pro-

cedures for individual

input/output

devices can be

found

in

the

IBM

System/360 Bibliography, GA22-6822.

This manual covers

information

required

by

the

operator

for

normal system

operation.

An

effort

was

made

to

el

imi-

nate

unnecessary

information.

Controls

and

indicators

used

only

by service personnel

are

not

described in this manual

but

are

covered in

maintenance

documentation

for

the

sys-

tem.

System/370

Model

145

performs

data

manipulations

and

input/output

operations

by

executing

microprogram rou-

tines.

The

routines

executed

are

determined

by

the

machine

language

instruction

being processed.

The

Initial Micropro-

gram Program Load (I MPL) disk

contains

the

microprogram

and

is

inserted

into

the

Console File before

power

is

applied

to

the

system.

When

power

is

applied

to

the

system,

the

microprogram

is

loaded

into

control

storage and

the

system

is

ready

to

load

the

operating system (OS, DOS, etc.)

or

a

standalone

pro-

gram. These programs are loaded by using

the

Initial Pro-

gram Load

(I

PL)

procedure

in

this

manual.

Operating

procedures

that

are necessary

before

a

problem

program

can

be

run

are:

1.

Disk Cartridge Insertion (IMPL disk)

2. Power-on

3. I

MPL

(automatic

with power-on)

4. I

PL

the

operating

system

(if required)

Whenever

power

is

removed from

the

system

these

proce-

dures

must

be

followed. When

power

is

dropped,

both

con-

trol storage and main storage are invalid.

A visual

contents

is

provided

to

aid in

quickly

locating

controls

and

indicators

on

the

system

control

panel.

To

evaluate

the

approach

used in

this

manual,

you

are

encouraged

to

use

the

Reader's

Comment

Form

in

the

back

of

the

manual.

Your

comments

will help

to

provide

better

documentation

in

future

manuals.

can be

operated

at

any

time

without

affecting system oper-

ation.

DISABLE

This

instruction

to

perform

its

Address Compare Control

This

switch

is

used with

the

ADDRESS COMPARE

and

the

STORAGE

SELECT

rotary

switches

and

determines

the

action

taken

by

the

CPU as a result

of

an address

compare

match.

SYNC/NORM

This

position

of

the

switch

is

the

normal

operating

position;

it provides a

sync

pulse

for

service use

and

does

not

result

in

a

stop

on

an address match.

STOP

The

STOP

position

is

for

customer

use

and

provides a soft-

stop

whenever an address

match

is

detected.

To

restart

the

CPU, press

the

START

key. With

the

switch in

this

posi-

tion,

the

TEST

is

on.

IMMED STOP

This

and

is described in
