INTRODUCTION
YOU’LL ADORE YOUR COMMODORE 264!
Welcome to the Commodore family! Whether you’re a beginner or an expert,
you'll be surprised how easy it is to use your Commodore 264 computer. The
Commodore 264 is easy to program . .. but you don’t have to be a
programmer to use it. You don't even have to know how to type!
Commodore’s full selection of COMMODORE 264 software makes it easy to
use your computer for business, home and educational applications. (And
don’t forget the games!)
You Bought The Best Computer
These special built-in features make your COMMODORE 264 the best home
computer you can buy:
• 64K RAM (60K available for BASIC programming)
• Full Typewriter Style Keyboard
• Optional Built in Software
• Screen Window Capability
• HELP Key
• 8 Programmed, Reprogrammable Function Keys
• Four Separate Cursor Keys
• Uses Most COMMODORE 64 and VIC-20 Peripherals
• 128 Colors (16 primary colors, 8 luminance levels)
• Over 75 BASIC Commands
• High Resolution Graphics Plotting
• Split-Screen Text With High-Res Graphics
• Graphic Character Set On Keyboard
• Keyboard Color Controls
• 320 x 200 Pixel Screen Resolution
• Reverse and Flashing Characters
• 2 Tone Generators
• Built-In Machine Language Monitor (13 commands)
What You Can Do With Your Commodore 264
The key to any computer is SOFTWARE, and Commodore has a full “menu”
of software available from your Commodore dealer. Specific applications
Include wordprocessing, financial calculations, learning activities, mail lists,
project planning, recordkeeping, home budget, investment analysis and
much more. Some software products combine several different functions,
such as “Triology,” which provides wordprocessing, an electronic
spreadsheet, database AND graphics!
Many models of the Commodore 264 have software built into the machine.
You can also buy Commodore software on plug-in cartridges, floppy
diskettes and cassette tapes. And of course, you can learn to program your
computer in BASIC, which comes built into your computer, or in other
popular computer languages such as LOGO.

Built-in Software
You may have purchased your Commodore 264 with one of several built-in
software packages that are ready to use as soon as you turn on your
computer. If your computer has built-in software, a separate manual
describing how to use the software is included. Built-in software on the
Commodore 264 is a Commodore first!
Commodore Software on Cartridge
For a long time, video games were the only software programs available on
cartridge. Now Commodore brings you large application programs such as
wordprocessing and business programs on cartridge...at prices you can
afford. Cartridges are convenient because all you have to do is plug them in
and start computing; you don’t need any additional equipment. There are
other advantages as well...for exampie, an electronic spreadsheet on
cartridge gives you more working space than an electronic spreadsheet on
disk.
Software on Disk and Tape
Commodore software also cornes on floppy diskettes and on cassette tape.
The Commodore Disk Drive lets you run Commodore disk-based software
and the Commodore Model 1531 Datassette lets you run tape-based
software.
Programming in BASIC — Over 50 New Commands
It’s easy to program your COMMODORE 264. Start by working through the
exercises included in this manual, and if you want to get more involved in
programming, Commodore offers several self-teaching courses such as
INTRODUCTION TO BASIC and our BOOKWARE™ series of books and
tutoriais.
The BASIC on your Commodore 264 is the most powerful BASIC ever built
into any Commodore home computer...it includes MORE THAN FIFTY NEW
BASIC COMMANDS including full GRAPHICS PLOTTING and PROGRAM
EDITING.
Programming in LOGO — Turtle Graphics and More
Many new computerists prefer to learn programming with LOGO, an easy
computer language created for beginners, which features the use of a
“turtle” to draw pictures and create graphs and charts. LOGO is rising
rapidly in popularity, especially in schools, and Commodore has a strong
commitment to this "friendly” programming language.

The MAGIC DESK •
If you’re a new computerist and you want to use your computer for
wordprocessing, calculations and other functions, but you really don’t want
to learn any special commands or instructions...try MAGIC DESK. This
unique Commodore software system uses PICTURES of familiar objects
instead of written commands, and uses the computer Keyboard like a
typewriter. The software is automatically linked to your disk drive and printer
so, for example, all you have to do is “point” at the picture of the printer to
print out a paper copy of something you’ve typed. Ask your dealer for a
demonstration.
Creating A Complete Computer System
As you develop your complete computer SYSTEM, you’ll find that
Commodore peripherals are priced so you can afford them, and designed
with superior features. Here are the major peripherals included in most
typical Commodore home computer systems:
Computer: Commodore 264
Display: Commodore Color Monitor (or your television set)
Storage: Commodore Datassette (tape recorder) or Commodore Disk
Drive
Printer Commodore Printer (several models) or 1520 Printer/Plotter
Modem: Commodore VICMODEM or Commodore AUTOMODEM
Controller: Commodore Joysticks
Where To Go From Here?
By now you’ve done enough reading and you want to get started. Here’s
what we recommend you do first: Send in your warranty card. Subscribe to
the Commodore magazine so you get the latest information on your
computer, and join the Commodore National User Club. Read this manual
and try the exercises. Try some software. Keep checking in with the
Commodore dealers in your area for new developments In software,

Now that you’ve opened the box containing your new C-264 box and found
this manual, the first thing that you should do is check to make sure that
you have ail the items on this list. You should have:
1. YourCommodore264
UNPACKING YOUR COMMODORE 264
2. The power supply
This is a biack box with a line cord
coming out of one end, and a round plug
coming out the other. The round plug
goes into the back of the C-264.
The other end has a standard three-
prong line plug that goes into a regular
wall socket.
3. The TV switchbox
This is the silver and black box that
connects to your antenna jack on the
back of your TV. You don’t need the
switchbox if you plan to connect your
C-264 to a monitor.
4. The RF cable
This is a thin black cable, with a single
prong jack at each end, used to connect
the TV switchbox to the RF output jack
on the side of the C-264. You don’t need
this cable if you are planning to connect
your C-264 to a monitor.
5. The user’s guide

If you don't find all these items in the box, check with your dealer
immediately for replacements.
Before you connect anything, you should look over these drawings of your
computer. These drawings identify all the outiets so you can set up your
computer system quickly and easily.

GETTING TO KNOW THE SWITCHES AND SOCKETS
THE RIGHT SIDE OF YOUR C-264
THE ON/OFF SWITCH
Your C-264 should be
turned off when you
Install or remove
cartridges or any
peripheral device such
as a printer or disk
drive. The OFF
position is marked so
you can be sure when
your machine is off.
THE RESET BUTTON
There are two ways to use the RESET button:
1. You can use the RESET button to clear your screen and reset your computer as If you'd just
turned it on. Just press the reset button once. Be careful: when you press the reset button,
you will lose any BASIC program currently in memory.*
2. If you want to reset your Commodore 264 and KEEP your BASIC program, hold down the
RUN/STOP key and then press the RESET button. When you do this, your C-264 goes to the
built in machine language monitor. Type an X and press the RETURN key to get back to
BASIC. Your program is still completely intact in the C-264 memory. Just type LIST to display
the program on your screen.
*Whe n you press RESET, C-264 automatically Issues a NEW command. This can be reversed. See the Comm odore 264
Programmer's Reference Guide for information on UNNEW ing your program after you've pressed the reset button by accident.
THE LEFT SIDE OF YOUR C-264
The socket and the
switch on the left side
of the C-264 (if you’re
facing it) both have to
do with TV con
nections. Neither is
used if you’re
connecting your C-264
to a monitor.
THE RF JACK
This is where you plug one end of the RF cable (the thin black cable). You can plug either end
Into this socket and the other end into the TV switch box.
THE HIGH/LOW SWITCH
This switch controls which channel will display your C-264 video output. Set the H/L switch to
L for output on channel 3. Set the H/L switch to H for video on channel 4.
You can use either channel 3 or 4 on your TV to display the video picture frorn your computer. If
you have a channel 3 TV station in your area, select channel 4, and vice versa. You’ll probably
want to experiment to see which setting gives you the best picture.

THE BACK OF YOUR COMPUTER
The sockets on the back of your computer connect a variety of accessories to your Commodore
264. Each connector is different. Be sure you plug each accessory into the right socket.
THE POWER SOCKET
The round end of the power cable fits in here. The power cable Is the one connected to the power
supply box. Plug the other end into a standard wall socket for three-prong plugs.
THE SERIAL BUS
You can plug a disk drive or a printer into this socket. If you want to plug in both, plug the disk
drive in here, and then plug the printer into the back pf the disk drive.
THE CASSETTE PORT
The Commodore cassette tape recorder plugs in here.
THE RS232 PORT
Accessories such as a modem and an RS-232 adapter plug in here.
THE MEMORY EXPANSION PORT
0 26 4 software cartridges and the 0 26 4 fast disk drive plug in here. When you install or remove
cartridges, be sure to turn off your 02 64.
JOY 0 AND JOY 1: THE GAME PORTS
You can plug )oy sticks into these sockets. The Commodore 264 uses specially designed joy
sticks available from your Commodore dealer.
THE VIDEO SOCKET
This is where you plug in the cable that connects a monitor to your 02 6 4. Although this socket is
an 8-pin connector, you can use a 5-pin cable in this socket as well. The Commodore 1700 Series
Color Monitor comes with an 8-pin cable for use with the C-264.

• You need to set up your C-264 somewhere with access to at least two
wall plugs: one for your C-264 and one for your TV or monitor.
• If you're installing a disk drive and a printer, you'll need additional wall
plugs.
• Your C-264 needs a place to sit that is a comfortable distance from your
TV.
• Make sure that your computer is OFF before you start the setup. Check
the ON/OFF switch on the side of the C-264 to be sure.
CONNECTING YOUR C-264 TO YOUR TV
If you are connecting the C-264 to a television set, you will need a small
screwdriver to attach the TV switchbox. The way you connect the switchbox
depends on what type of antenna connection your TV set has.
NOTE: If your antenna is connected to your TV by a single round-ended
cable (the 75-ohm co-ax type), you will need either the 3CX) ohm to 75 ohm
adapter, which came with your TV, or you must get a replacement 75 ohm to
75 ohm switchbox. The adapter is a small plastic part with a co-ax connector
on one side and two screws on the other. If you do not have orie, it is
available at most electronics stores. Once you attach the adapter to the co
ax connector on your set, you can follow the rest of these instructions.
STEP 1. Disconnect the antenna from your TV: use a screwdriver to loosen
the screws on the TV. Remove the two antenna leads.
STEP 2. Connect the TV switch box to the TV where the antenna leads
were: use a screwdriver to attach the leads on the box to the
antenna Input screws on your TV.
STEP 3. Connect the antenna to the switch box: use a screwdriver to
attach the leads from the antenna to the screws on the switch
box.
If you have the round coax type antenna connection on your TV, and you
have a replacement 75-ohm TV switch box:
STEP 1. Disconnect the antenna from your TV: unscrew the antenna wire.
Just unthread it by hand.
Connect the switch box to the TV: hand turn it onto the antenna
input post on your TV. *
Connect the antenna to the switch box: hand turning the antenna
cable into the switch box.
Once the switch box is in place, get the RF cable (the thin, jack-ended cable)
that came with your C-264. Plug one end into the socket in the top of the
switch box. Connect the other into the socket marked RF on the left side of
your computer.
SETTING UP YOUR C-264
STEP 2.
STEP 3.
5

Once you’ve attached the switch box to the TV, you never have to do it
again. When you want to use the computer, just move the switch to
COMPUTER. When you want to watch TV, just move the switch to the TV
position. The switch box will not interfere with vour TV reception.
SELECTING A CHANNEL ON YOUR TV
As we explained earlier, your TV should be set on either channel 3 or 4 when
you are using your computer. Don't choose a channel that broadcasts in
your area. If you use channel 3, set the H/L switch on the side of the
computer to L. If you use channel 4, set this switch to H.
CONNECTING YOUR COMMODORE 264 TO A MONITOR
If you’re connecting your computer to a monitor instead of a TV, follow the
instructions in the manual that comes with the monitor. Hooking up a
monitor like the Commodore 1703 Color Monitor is simple. It requires only
one cable that goes directly from your monitor to the VIDEO socket on the
back of your computer.
FINAL STEPS
1. Attach the power supply cable with the power box to your C-264. Plug
the round end of the cable into the POWER socket on the back of the
computer; plug the power supply into the wall socket.
2. If you are using a TV, make sure that the setting on the modulator (H/L),
and the channel on your TV (3 or 4) are in agreement. Make sure that the
switchbox is set to the COMPUTER setting.
If you are using a 1702 or 1703 monitor, use the rear jacks, and check
that the back/front switch is set to BACK.
3. Turn on your computer. fThe switch is on the right side as you face the
C-264.)
4. If all went well, this message will appear on your screen:
COMMODORE BASIC 3.5 60671 BYTES FREE
READY.
The flashing cursor under the READY message tells you that the C-264 is
waiting for you to start typing. The background color will be white, while the
letters will be printed in black.
5. Check the troubleshooting chart if you have problems. You may need to
adjust your TV set to get a sharper picture.

NOTE: Some TV sets cannot display the entire C 264 screen. Instead, their picture crops off the
leftmost and rightmost column of the C 264 screen display. We recommend you use a different
TV set or a monitor such as the Commodore 1702 or 1703 color monitor.
If this is not possible you can remedy this problem by pressing the ESCape and N keys. This
reduces the computer screen display size so the entire picture can appear. You rnust repeat this
each time you turn on your computer.

CHAPTER
USING THE KEYBOARD
AND THE SCREEN
A tour of the keyboard.
The special keys.
The graphics keys.
The programmable function keys.
The HELP key.

TRY TYPING THIS ON YOUR KEYBOARD:
1 PRINT “your name”
2 PRINT “HAS A NEW 264"
RUN
press the M>|l|;™ key
pressthe iiH M 'B key
pressthe B aiM fli key
A TOUR OF THE KEYBOARD
Many of the keys on the C-264 keyboard are like the keys on a typewriter, but
every key can do more than a typewriter can. In this section, we’ll show you
how to use the special keys, like the ^ ] key and the cursor arrow keys.
And we’ll show you the extra powers of every key, including how to print the
graphic symbols on the fronts of many of the keys.
While we guide you on the tour of the C-264 keyboard, you should find the
keys and practice using them.
THE SPECIAL KEYS
RETURN
You have to press the RETURN key at the end of each line of instructions
you enter on your Commodore 264 keyboard. You might think of this key as
an ENTER key because RETURN actually enters information and instructions
into the computer.
SHIfT
This key works like the shift key on a regular typewriter. Your C-264 has two
SHIFT keys and a SHIFT LOCK, which works like the shift lock on a
typewriter.
With the SHIFT key, you can get the graphic symbol on the right side on
each graphics key when you are in uppercase/graphics mode.
Your C-264 is automatically in uppercase/graphics mode when you turn it on.
In uppercase/graphics mode, all the letters appear uppercase when typed
without the SHIFT key.
9

The SHIFT key gets upper case letters when you are in upper/lowercase text
mode. You can tell you’re in this mode when the letters you type are in lower
case except when you use the SHIFT key. You can go back and forth
between uppercase/graphics and upper/lowercase text modes by pressing
the SHIFT and @5] key at the same time.
RUN
STOP
Press this key to tell your C-264 to STOP what it is doing and give control
back to you. When the C-264 is running a BASIC program, you can stop the
program with this key.
When you hold down the SHIFT key and type this key, RUN tells the C-264 to
fc>ad and run the first program on a disk in the disk drive.
✓ ^\
THE CURSOR KEYS ^ ] | \
It’s easy to move the cursor quickly around the screen in any direction. Just
press the cursor arrow key that points in the direction you want to go. Like
ail keys on the C-264 keyboard, each cursor key has a REPEAT feature. This
automatic repeat keeps the cursor moving until you release the key.
NOTE: You can move the cursor over letters and numbers on the screen
without affecting those characters.
'iN 5 T / W
You can INSERT and DELETE characters from the line you are typing by
pressing this key. When you press DEL, that character immediately to the
left of the cursor disappears, and the cursor moves over to where the
missing character was. You can use the cursor keys to go back to the
middle of a line and then use DEL to DELete a letter. When you do this, the
letter to the left is deleted, and the rest of the letters on the line move over
one space to the left to close the gap left by the deleted letter.
You can open up space to insert letters and numbers by using the SHIFT
and INST keys. Space opens to the right of the cursor; the cursor itself does
not move. When you insert space in the middle of a line of letters, the rest of
the line moves to the right.
The INST/DEL key saves a lot of time when you want to edit or change what
you've typed.
10

CLR/HOME
When you press this key, the cursor immediately moves to the top left
corner of the screen. This is called the HOME position. Your screen stays
the same. If you hold down the SHIFT key and press CLR/HOME, not only
does the cursor move to HOME, but the screen clears. All that remains on
the screen is the blinking cursor at the top left corner of the screen. Press
HOME twice to cancel a screen window and return the cursor to the HOME
position.
KTW
This key doesn’t do anything by itself. It always works with another key. The
CTRL key works like the SHIFT key: you must hold it down while you press
the other key.
1. As the COLOR KEYS section explains, CTRL and a color key let you
choose the color of the text printed on the screen.
2. You can pause a program that is PRINTing on the screen by pressing
CTRL and the S key (press any key to resume program output).
3. CTRL is also used with the reverse on/off and flash on/off keys.
In addition, some software programs that you buy use the CTRL key for
special functions.
m
Like the CTRL key, the Commodore key doesn’t do much by itself. It has
four functions:
1. W henu sedw lthth eSH IF T key ,the © keyletsyouswitchbetween
uppercase/graphics mode and upper/lower case text mode.
2. When you’re in either mode, the © key acts as a shift to let you type
the graphics symbol on the LEFT side of each key. Just hold down ft^|
and press the graphic key you want.
3. When you want to change the color of the screen characters to one of
the 8 colors listed on the BOTTOM row on the face of the color keys,
press §ij and the color key you want.
4. When you want to slow down a scrolling program display, hold down the
jQt| key. The display scrolling speed slows down considerably. When
you release the key, the display resumes normal speed.
11

THE COLOR KEYS
• If you want one of the 8 colors listed on the TOP row on the front of the
color keys (like BLacK), just hold down the CTRL key and then press the
color key with the color you want.
• If you want one of the 8 colors listed on the BOTTOM row on the front of
the color keys (like ORaNGe), just hold down the @ key and then
press the color key with the color you want.
After you change the color, every character typed AFTERWARDS is in the
color you last chose.
You can change the colors of the letters and numbers on the screen to any
one ot the 16 colors available on your C-264. It’s simple to do:
Your C-264 lets you print the reverse image of any character. In other words,
if you are using black letters on a yellow background, you can use the
reverse image keys to print yellow letters on a black background.
Here’s all you do to get reversed images: press the CTRL key and the RVS
ON key. Now everything you type will be displayed in reverse until you press
the CTRL and RVS OFF, the RETURN key, or theESCape key. This will
return you to typing normal (non-reversed) characters.
u ra ft iTTOTk
iNEEHk ^EXuwk
You can make the characters on your screen flash continuously. Just press
CTRL and the FLASH ON key to make whatever you type flash. Typing CTRL
and FLASH OFF, RETURN, or ESCape lets you type normal (non-flashing)
characters again.
12

ESCAPE
Use the ESCape key to perform many special screen editing functions, such
as setting the top and bottom of a display window.
Press the ESCape key and one of the letter keys listed below:
A Automatic insert mode
B Set the bottom of the screen window
C Cancel automatic insert mode
D Delete current line
I Insert a line
J Move to the start of the current line
K Move to the end of the current line
L Turn on scrolling
M Turn off scrolling
N Return to normal screen display size
0 Cancel insert, quote, and reverse modes
P Erase everything up to the start of the current line
Q Erase everything up to the end of the current line
R Reduce screen display
T Set the top of the screen window
V Scroll up
W Scroll down
X Cancel the escape function
SETTING SCREEN WINDOWS
Windows let you define an area of the screen as your work area. Everything
you type after setting a window will take place within the window (the lines
you type, LISTs of your programs, etc.) without affecting the rest of the
screen. You can put a window anywhere on the screen.
To set a window, follow these steps:
1. Move the cursor to the screen position you want as the top left corner of
the window.
2. Type the ESCape key, then type T.
3. Move the cursor to the screen position you want as the bottom right
corner of the window.
4. Type the ESCape key, then type B.
All screen output is confined to the window area you defined. Cancel the
window by pressing the HOME key twice. The cursor will go to the HOME
position.
THE GRAPHICS KEYS
As we mentioned before, when you turn on the C-264, it is in uppercase/
graphic mode. When you’re in this mode, you can type the full set of more
than 60 graphics you see on the fronts of many of the keys, as well as a!l
13

upper case letters without using the SHIFT key. The SHIFT key lets you type
graphics, not uppercase letters.
There are two graphic symbols on each graphics key:
• To print the graphic symbol on the right, hold down the SHIFT key while
you press the key.
• To print the graphic symbol on the left, hold down the fC*j key while
you press the key.
You can create pictures, charts, and designs by printing graphics side by
side or on top of each other, like building blocks. Chapter 6 explains more
about graphics.
You can switch between uppercase/graphics mode and upper/lowercase
mode by pressing the SHIFT and jC*f keys at the same time. In either
mode, type BASIC commands witn6ut holding down the SHIFT key.
In upper/lowercase text mode, you can type upper and lowercase letters, just
like a regular typewriter. Otou will have to shift for uppercase letters.) You
also can use all the graphics on the left side of the graphics keys, which you
type the same way as in uppercase/graphics mode: hold down §£] and
press the graphics key. The left side graphics are ideal for creating charts,
graphs, and business forms.
SPECIAL SYMBOLS
The C-264 keyboard also contains special symbols not found on many
typewriters, or even on most computers. These special symbols include the
English Pound sign (£), pi ( n ), greater and less than signs ( < > ), brackets
( f J), and arrows ( t — ). These special symbols keys are used in
programming your C-264.
