A Guide to the

IBM

System/370

Model 145

This guide presents hardware, programming systems,

and other pertinent information about the

IBM

Sys-

tem/370 Model 145 that describes its significant new

features and advantages. The contents are intended

to acquaint the reader with the Model 145 and

of benefit in planning for its installation.

Associated with this guide are four optional supple-

ments that describe operating systems for the

Model 145 that support a virtual storage environment.

Each supplement has its own form number and must

ordered individually,

required. Optional supple-

ments are the following:

• DOS/Virtual Storage Features Supplement*

•

as/Virtual

Storage 1 Features Supplement

(GC20-1752)

•

as/Virtual

Storage 2 Features Supplement

(GC20-1753)

• Virtual Machine Facility/370 Features Supplement*

*Availability to be announced

Third Edition (August 1972)

This

a major revision obsoleting GC20-1734-1. Text has been added or changed to in-

clude information about the following: EC mode; dynamic address translation; channel

indirect data addressing; program event recording;

CPU

timer and clock comparator; new

System/370 instructions; store status facility; integrated storage control for 3330-series

disk storage; 3830 Storage Control Model 2; virtual storage concepts, advantages,

terminology, and performance factors; DOS/VS, OS/VS1, and OS/VS2 support

Model 145 hardware features;

DOS

Version 4 support; and miscellaneous additions and

corrections. Changes to the

text

and illustrations are denoted by the vertical line to the

left

now structured as a base publication

for which optional programming systems supplements describing virtual storage operating

systems can be ordered.
