WELCOME TO YOUR PET COMPUTER
Congratulations and welcome to the exciting new world of personal computers. By selecting
the PET 2001 you have eliminated the problems of getting a personal computer system running. Your time
is now available for learning the functions and capabilities of your PET. In fact, if you follow a few simple
procedures outlined in this manual, you should be able to achieve initial operation of your Pet 2001 within
a short period after unpacking the shipping container.
The potentials of your PET are virtually limitless. This book, by its very nature, is limited. Questions
will
arise that this book has not covered or even anticipated.
Write to us at Commodore with your questions. We will answer many that you and other users will pose
with a newsletter we'll be sending out from time to time to users.

PET is a Personal Electronic Transactor. Everything is complete in one steel cabinet. It contains a CRT
board, keyboard, computer board, and a Commodore supplied cassette. There is a built-in black and
white television monitor, which displays characters in a format that appear to you to be forty characters
by twenty-five lines.
At the heart of your PET 2001 is an MCS 6502 microprocessor. This microprocessor totally controls
operation of the screen, keyboard, cassettes, and additional peripherals which can be added to the PET.
The product is so construed that you cannot damage the PET from the keyboard. The operating system
cannot be destroyed because the computer software, or operating instructions are contained in a fixed
memory. (Called Read-Only·Memory) This allows both the first time user and the sophisticated user to
use the PET with impunity.
In order to satisfy the needs of the serious user as well as the first time user of a computer product, we
have used three formats in this manual.
Summary discussions in this type font are designed to answer the questions of
a
professional
programmer. When you are first using your PET manual, read these sections lightly and spend time on the
more detailed explanations which are in the type font of the preceding paragraph. After you have used the
PET
a
bit, the italicized summary
sections
will be useful when you want to review how
a
particular
instruction works.
The third type of format gives a detailed description of how the PET Implements a section. These
sections are for people who use the PET at the machine level. The first time reader may find these
sections difficult to follow and we recommend helshe use them only on re...eading the material when
more familiar with the PET operating systel\1. The language which you will use to communicate with your
PET is called BASIC, an acronym for Beginners All-purpose Symbolic Instruction Code.
