TRICKY TUTORIALS(TM)

There are many things thai ,Me ATARt computers can do either beller or easfer than o l hersmall computers The folloW ing series

01 programs Is designed lor anyone who Is at teasllamlliar with BAS IC p rogramming. What each tu torial o ffers Is similar to an

extensive magazine article with all dlsousslon In as simple language as IS possible. plus you gel MANY eKsmples already typed In

and running Theta Is IItlle overlap In what Is taught, so each lutorial wililurther convince you Ihal buying an ATAR t was Ihe rlghl

ChOice!

• 1 DISPLAY LISTS

This program teaches you how to alter the program in Ihe

ATARI that controls the lormat of the screen. For 8)(ample.

when you say graphics 8 the machine responds with a large

graphics 8 area at the lop 01 the screen and a small text area

at the bottom. Now, you Will be able to mix various modes on

the screen at the same time Just think how nice your pro--

grams could look With a mix of large and smaillexi. and both

high and fow resolution graphIcs The program has received

rave revlews tor the way II does all the calculations of the dIf-

ficult things (like counting scan lines). You will guiCkly be able

to use the subroutines Included in your own programs. 16k

memory requtred lor tape - 24k for disk.

#4 BASICS OF ANIMATION

ThiS p rogram shows you how 10 anlmale sim ple shapes

(wilh sound using the PRINT and PLOT commands, and also

has a " Ice 1I111e PLAYER/MISSILE G RAPHICS game you can

play WIUl The P/ M example Is well commented and will get

you s'tarted on this complicated sublect (more l ully explained

In TTIfS). This would be an excellent way to start making your

p rograms come alive with movemen ll Recommended tor be-

g Inning users. 16k lape - 24k disk.

#5 PLAYER MISSILE GRAPHICS

This Is the big onel We start by showing how tocrealeaslm -

pie shape called a player. lhen take you th rough over 25 exam-

ples until you have created a com plete business application

and a small game. AlSO , we Include a utility to c rea te th e

shapes and choose the colors, then store the players and mis-

slas In data statements. Later YOUR programs bring these

shapes back in when needed. Plus m uch mo re! 32k tape o r

disk.

1/2 HORIZONTAL & VERTICAL SCROLLING

The information you put on the screen, either graphiCS or

text, can be moved up, down or sideways. This can make for

some OIce eHects. You could move only the lext on the bot-

tom half 01 the Screen or perhaps create a map and then move

smoothly over it by USIng the joystick Includes 18 examples

With severaJ using a small machine language subroutine lor

smoothness. As always, our examples can easily be used in

your own programs. 16k tape.24k disk.

One 0' the famous programmers for o ur great m ach ine of-

fers this one through us. Un less you have spent many hou rs

experimenting with the four voice channels, you w ill learn alo t

from this onel The nicest part is t he MANY examples of special

sound effects that you can refer to w hen you need them for a

program or to impress a friend. 16k tape - 24k disk.

#6 ·SOUNDS & MUSIC

#3 PAGE FLIPPING

Normally you have to redraw the screen every lime you

change the picture or text. Now you can learn how to have the

computer draw the next page you want to see while you are

slill looking at the prevIous page, then flip to it instantly. You

won', see it being drawn so a complicated p icture can seem 10

just appear. Depending on your memory size and how compli-

cated the picture, you could flip between many pages, thus

aJlowing ammatlon o r other special effects. We have found

that many people skip this tutorial either because il sounds

hard, or they think they will never use It. The basic method

takes only 12 lines and the usefulness is infinite. 16k tape - 24k

disk.

S~~t~ Cr~z

S~~t~~r~

Hi~ First let us thank you for purchasing our programs. We want to

start out by telling you a little about ourselves and our company.

Santa Cruz Educational Software is the result of .ev.r~l local

programmers who initially purchased the ATARI computer as a home

machine around the time the 800 was first sold. At that time, and even

today~ we found a lack of information about how to u.e the power of

the machine. As you have seen in a few of the better programs being

sold, the ATARI can do more than any other computer in it's price

range, but how could we learn the many "tricks" that were contained

withen the machine??

Well, our local club, although it had several HUNDRED members,

ignored most of our questions. Fortunately other clubs across the

country have some excellant newsletters full of programs and facts.

Also~ ATARI(tm) has given we owners the Operating System and Hardware

manuals. Finally, many magazine articles and several books have be.n

published.

All this is great for programmers, but what about the average

owner who doesn't understand much of what is said in the magazines?

Even as a programmer~ I have to spend many hours studying all of the

information that is now available inor der to understand some of unique

things about our machine.

The story ends when I asked some local club members to submit

their best programs for us to offer to others at the lowest possible

price, ie. a price WE WOULD be glad to pay to buy these programs. I

myself wrote most of the TRICKY TUTORIALS(tm) ~nd the MASTER MEMORY

MAP. Now, others across the country have offered programs for us to

sell, all meeting the goal of: minimal on fancy artwork and a few

spelling errors, but worth ever y penny .

Write us with new ideas or memory locat i ons to share, and if it's

something we can use, a reward will be sent back to you as soon as we

can. Also, please remember that this is only a part time business. We

are usually late in getting new programs out due to last minute

debugging at midnite<no kidding, I d o all this after my regular job).

This doesn"t mean we don't care!

My thanks to all of you who have raved about the Tutori~15. I will

try to keep a new one comming out every three months or less, and also

to get out those bugs that remain.

HOW TO LOAD

••••••••••••••

TAPE ••••••

First, if you haven't cleaned your tape recorder heads lately,

please do so now. SEE ANY STEREO SHOP FOR THE RIGHT TOOLS. Place th~

tape with the label side up in your recorder. Make sure it is r~wound

and also reset the counter to O. Push PLAY on the recorder. TYPE

RUN"C:/I AND PRESS RETURN. If this doesn't work you might try CLOAD. We

also include a backup program on the shorter programs we sell (not the

TUTORIALS), and these sometimes require CLOAD. If the program won't

start to load, try positioning the tape forward or backward a little

bit at a time. The easiest way would be to LISTEN to the "noise" on

the tape with a regular tape recorder. When you find the steady tone

that lasts for about 8 seconds, you have the beginning of each

program. We recommend you write down the number on your recorders

counter as each program starts. This will make it easier to find each

part later on if needed. W. occa.ionally get a bad tape from our

supplier, so if yours won't load on both your own 410 and a friends

(or your DEALERS), call (408) 476-4901 for a replacement.

Once the program starts, it will load in the remaining parts. The

multiple parts are needed so that machines with only 16k can enjoy the

TRICKY TUTORIALS. With more memory you can go beyond these simple

tutorials. After each part, the computer will beep. This is your

signal to press return to load in the next part. SOMe newer programs

will start the next part without pressing return. Most programs will

run themselves when done loading.

The reason for several methods of running tape. is that as we

improve the programs, we change the masters; however, the manuals are

printed in large amounts, so changes are VERY hard to get into your

manuals!

••••••••••••••••••••••••••••••••••••••

DISK•••.•

To load & run the disk you first have to turn on the drive. When

the busy light goes out place the disk in the drive. Now turn on the

computer with the basic cartridge in place and the program will load

each part and run by itself (aren't disk drives nice!).

DISPLAY LISTS

Educational SoftlNare

Display Lists consists of a set of

programs that are simple to use, but

deal WiTh a compl icated subject. Until

now, only a few programmers have

understood enough about modifying the

ATARI's Display Lists. Using the

examples and manual inside, you have

only to follow a few simple directions

to create your own custom screens.These

scr~ens can consist of any of the

ATARI'S regular Text and Graphics modes

plus 5 new ones. Imagine up to 20 modes

on the screen at once~ ••• real special

effects in all your programsl

This program requires very little

actual programming experience. It is

especially designed to allow you to use

iT now, and go back and learn the actual

method within the program at any time in

the future.
