SEPTEMBER, 1985 


Dear members. 

Herewith the September newsletter. The club seems to be 
on a continuous upward path : consistently interest ins 
meetings are attracting large turnouts; considerable volumes

American confidence in Atari's future is beins reflected in 
the many new software titles which are now becoming available 
both here and overseas. Beauty! 

OCTOBER MEETING 

As is usual, our next meetins will be held at the 
"Loaves and Fishes" ‘‘-.behind the Anglican Cathedral in 
Molesworth St. in central Well inston) beginning at 7.38 pm. 
on 3 October. Features arranged so far include 1 
a demonstration of what we believe is the first Atari 520ST 
in Wei 1 inston; 

an exposition on "Spreadsheets", usins Visicalc as the 
vehicle, by Dennis Dawson; 

a demonstration of some new commercial software.! and 
the new club tape and new disk, 

CLUB DISKS 

Both disks #8 and #3 will be demonstrated. I apologize 
for not speak ins about #8 last month but, truth to tell, i" 
could not remember what was on it! Gavin Bateson, who 
mass-produces the monthly disks, was soins on leave so #8 was 
constructed very early in the piece.

The W.A.C.E. Book Library 


The book library is a free service which the club extends to its 
members for the purpose of aiding knowledge in the field of Atari 
computers. The library is constantly being augmented with new books and 
classics in all areas, from advanced machine language tutorials to 
games reviews and from simple application books to alternative 
programming language texts. In order to borrow a book from the club 
library, simply select it during the time allocated in the meeting, 
take it to the librarian who will write your name and the date down in 
the master list, and then take it home for one month. A limit of two 
books per time exists in order to allow everyone a chance to see the 
books. Please ensure that books are returned at the next W.A.C.E. 
meeting and that they return in good order. There is no rental fee, but 
a fine will be charged on damaged books. 


Out-of-Town members should correspond to Neil Upton, the committee 
member in charge with Out-of-Town members if they wish to borrow a 
book. 


It is not possible to reserve a book, but providing the system 
works correctly, all books should be on hand at each meeting since they 
will have been returned one meeting after being borrowed. The complete 
library list followsi

T'ideo Monitors: Wide Array of Choices 


By PETER H. LEWIS 

fpESS than a decade ago most 
; ij computers did not have video 
jjgln monitors. Instead, humans 
communicated with the ma¬ 
rine by feeding bundles of key- 
unched computer cards into a chat* 
sring box. Some computers also had 
anks of toggle switches aftd blinking 
ghts, and by deciphering the pat 
trns of lights the user could get a 
tirly good idea of the mischief the 
lechanical brain was doing. 

The video monitor, along with the 
ryboard, is now the most common 
put device for personal computers, 
id this simplifies things greatly. But 
wording to the recently discovered 
list Law of Conservation of Confu- 
on. which bolds that a gain in sim- 
icity must be offset by a corre- 
«nding rise in complexity, choosing 
e right video monitor is not as easy 
it looks. 

The choices are varied. Many peo- 
e attach their home computers to a 
are color or black-and-white televi- 
3n set, and this works well for many 
mple applications. Others buy the 
mputer, keyboard and monitor 
sm the same manufacturer as a 
mdied package, and this is rarely a 
tong choice. Still others, in the 
irit of audio connoisseurs who mix 
id match stereo components, choose 
mmpatible video monitor only after 
idying a range of offerings: mono- 
rome (one-color) in green, amber 
black and white; composite color, 
-RGB (red-green-blue), in regular 
high-resolution. 

Although the monitor may appear 
be a simple television set, there are 
pnificant differences. Television 
ts are designed to receive a video 
mal that has been altered, or modu- 



DC-9 color monitor 


ited, to travel the airwaves at radio 
■equencies. Computers, on the other 
and, send out an unmodulated video 
gnal, which then must go through an 
F (radio frequency) modulator to 
i received by the television set, 
hich in turn demodulates the signal 
id transforms it into Space Invaders 
■ whatever. The RF modulator is 
lilt in to some home computers, or it 
m be purchased separately at Radio 
lack or other electronics stores for 
ss than $50. 


A color television set may be ade¬ 
quate for simple applications such as 
-home banking or playing video 
games, but a computer monitor is 
„ recommended for more serious appli- 
. cations such as word processing, 

| -spreadsheets or detailed graphics. 

}- - In general, monochrome monitors 
-are recommended if the computer is 

- to be used primarily for word pro- 
_- cessing or other clerical chores. For 
~ -flashy graphics and games, however, 

* 'color is best. 

2't - A color television set is much more 
‘■-limited than a monitor in the amount 
i *of information it can receive and dis- 
j ’"play. 

I - ‘ Images on both a television and a 
|-monitor are made up of dots of light. 

■ »One factor that determines how 
s - tightly the dots can be spaced, and 
r “thus how highly resolved, or sharp, 

! -.the image will be, is bandwidth. A 

- television set, which must space its 
,--signals to leave, room between chan- 
ji^nels, has a bandwidth of about 3.5 
J > megahertz. This allows only about 40 

.columns of characters, a significant 
. -constraint on word processing or 
.-spreadsheets. A monitor, which in ef- 
Vtect has only one channel, has more 
•- -room for signals and can accommo- 
, *date up to 30 megahertz in the most 
-expensive RGB models. 
u.' Another factor in color monitors, 
‘said Keith Shaw 1 , a marketing associ¬ 
ate at Princeton Graphics Systems of 
.Princeton, N.J., is dot pitch, the dis¬ 
tance between the centers of individ¬ 
ual picture elements (pixels) of the 
same color. The more tightly packed 
'thepixeis, the sharper and crisper the 
screen image will be; colors will be 
brighter. For home television sets, 
-Mr. Shaw said, the dot pitch is usually 
-.7 to .9 millimeters, as against .28 to 
.31 millimeters for Princeton’s top- 
- » line color monitors. Two of the best 
color monitors are Princeton’s HX-12 
($695) and HX-9 ($650). 

- Color monitors are classified as ei¬ 
ther composite or RGB, and this 
-refers to the type of video signal. 
Composite monitors, like color televi¬ 
sion sets, receive one modulated sig- 

- nai containing all the elements of the 
. color video image, then “comb” them 
.apart into the constituent colors red, 

5 green and blue. In an RGB signal, the 

• red, green and blue signals are re¬ 
ceived and moved to the display 

-screen separately. RGB monitors 
give a sharper, brighter image, but 
they are more expensive, too. Before 
' buying one, make sure the computer 
can handle RGB; the Commodore 64, 
for example, can support only com¬ 
posite monitois, while the I.B.M. PC 
" ‘and Apple He’s can run an RGB 
monitor only if they are equipped 
-with a color graphics card. Check 
a with the dealer before making a pur¬ 
chase. f 


Choosing One Color 


Monochrome monitors are less ex- 
'pensive than color monitors and are 
-^preferred for such eyeball-intensive 


casks as word processing. Even 
though there is only one color to 
choose, however, the choice can still 
be confusing: amber, green or black 
and white? 

Each has its proponents. Amber 
monitors are the standard in Europe, 
where researchers assert that shades 
of amber cause less eye strain than 
shades of green. Green is the most 
commonly offered color in the United 
States. Some companies make black- 
on-white or white-on-black screen 
images, saying they more closely 
resemble the paperwork that over¬ 
flows most offices. Studies suggest 
that black-on-white images are hard 
on the eyes for clerical use, but the 
I Apple Macintosh has a black-on-gray 
screen that does not seem particu¬ 
larly stressful. 

In the absence of definitive scien¬ 
tific studies, the amber versus green 
debate seems to come down to a mat- 
ter of personal preference, said Mr. 
Shaw of Princeton Graphics. “It does 
seem like more people prefer 
amber,” he said, but he added, 
“We’ve searched long and wide to 
find some sort of scientific backup to 
substantiate claims that other mann. 
facturers have made, but there 
! doesn’t seem to be anything." 

For those who use color monitors 
for clerical tasks, some users report 
they can reduce eye strain by going 
light on the reds and blues. This is un¬ 
verified, but might be worth a try.

Data Retrieval 
mprovements 

Palo Alto, Calif. 
Text written on paper must be in a specific order, 
is article, for instance, has a particular order of 
ragraphs, and the reader will normally follow it 
>m beginning to end in sequential fashion. 

But computer-based information need not be 
und by such restrictions imposed by paper. With 
mputers it is possible to have individual small 
ckets of information that can be called up in any 
ier the reader desires. The concept has been 
lied nonsequential text, or "hypertext,” and it is 
iwly gaining adherents in computer science. 
‘You can provide a document that people can 
ik at at various levels," said Frank G. Halasz, a 
search scientist at the Xerox Corporation's Palo 
to Research Center. Last week Xerox introduced 
itecards, a software program embodying the 
ias of hypertext. 

The concept is not an easy one to grasp, but one 
alogy might be tours through a museum. Some 
ovide a single route that takes a visitor past all 
i exhibits. Others would concentrate on certain 
hibits and bypass others. 

Similarly, an electronic hypertext document 
mid offer choices. For instance, a person reading 
rypertext article about a company would have a 
oice of how much detail he wanted on the compa- 
’s history and how much .on finances. The con* 
pts have been used in some electronic novels and 
mputer games, in which the plot changes de. 
nding on choices made by the player. 

But hypertext would also allow users to link dif- 
rent documents. Encyclopedias, for instance, 
iw often contain cross-references to other arti- 
ss, which in turn contain cross-references to still 
hers. But following the cross-references is tedi¬ 
ts. With a hypertext encyclopedia, a reader could 
ess a button and jump to the relevant part of the 
■oss-referenced article and from there to another 
ess-referenced article. In short, one could hop 
om article to article following a given idea. Simi- 
rly, instead of just seeing a reference to another 
x>k in a footnote, a reader could move immedi- 
:ely to the relevant part of that book. 

This system is more advanced than traditional 
ita banks, which permit the retrieval of docu- 
lents quickly, but do not allow movement from 
le document to the middle of another. 

The first hypertext system was developed in the 
irly 1960’s by Douglas C. Engeibart, then at the 
tanford Research Institute. As part of the same 
reject, Mr. Engeibart also developed a device for 
nmrolling the computer that is only now coming 
ito widespread use — the mouse. Mr. Engelbart’s 
astern is marketed by Tymshare, now part of Mc¬ 
Connell Douglas, under the name Augment. 

The term hypertext was coined in the mid-OO’s by 
ed Nelson, an author and futurist. His attempt at 
resting such a system, known as Xanadu, has 
sundered for lack of financing. 

It is only now, however, that the computer tech- 
ology has improved enough to allow such pro¬ 
rams to become more widespread, and a few sys- 
jms are being developed. At Brown University, a 
ypertext system has been developed to work on 
he Macintosh computer. Next year it will be tested 



Andrew Pollack 




in an English course as a way of providing students 
with information and comments on the literature 
being read. 

Tektronix, an electronics company in Beaverton, 
Ore., is testing such a system for managing infor¬ 
mation in software development in its computer 
laboratory. Such software projects involve huge 
numbers of documents and when a change is made, 
such as in a design specification, it often requires 
changing many documents, said Norman Delisle, a 
senior software engineer at the lab. With the hyper¬ 
text system, with the relevant parts of the various 
documents connected by electronic links, it is easy 
to make those changes, he said. 

Knowledge Systems Inc. of Pittsburgh sells in¬ 
formation management software using the princi¬ 
ples of hypertext. 

• • • 

A big use of such systems might also be in com¬ 
puter programs that help people write papers. Sim¬ 
ple concepts related to hypertext are appearing in 
personal computer programs such as Thinktank by 
Living Videotext Inc. and Framework by Ashton¬ 
Tate. These programs, sometimes called outline 
processors or idea processors, allow users to 
manipulate blocks of data into outline form. 

Xerox’s Notecards also aims at this market and 
is more sophisticated. It is, as its name implies, the 
electronic version of the system long used by col¬ 
lege students, of taking notes on index cards. Paper 
index cards, however, must be arranged in se¬ 
quence. The student might not know yet whether a 
piece of information about George Washington’s 
battles will be in the section of the report dealing 
with George Washington’s life or in the section 
dealing with the Revolutionary War. But with 
paper index cards he must choose or else main, du¬ 
plicate cards. 

- With Notecards, however, ideas do not have to be 
organized into a linear outline. The system allows 
any card to be connected to any other in a complex 
network. One can envision the system as consisting 
of cards with lines between them, like a map of 
cities and roads between them. 

Of course, the report writer eventually must or¬ 
ganize the various thoughts into a sequential pat¬ 
tern, if they are to be printed on paper.

Here They 
Gome: The 
Smarter PC’s 

Personal computers are down, 
but they are not out. Makers 
are betting that a surge of new 
devices will spark the industry. 

Personal computers once were bally- 
hooed as indispensable. For many peo¬ 
ple, they were not. But it’s too soon for 
skeptics to laugh—a new beginning for 
personal computers seems at hand. 

Coming to market soon is a new gen¬ 
eration of PC products that could in¬ 
ject life into the industry. On the way 
are improved sound and graphics fea¬ 
tures, programs that do not require ex¬ 
tensive training, devices that allow 
computers to control home utilities 
and appliances, and better educational 
products. 

Stirring the most interest is the pow¬ 
erful Amiga, which Commodore Inter¬ 
national expects to sell by September 
at a base price of $1,295. It has stun¬ 
ning animation and graphics capaci¬ 
ty-over 4,000 colors—and replicates 
the sound of an orchestra across four 
audio channels. 

Whether there are millions of arm¬ 
chair artists, designers and music ar¬ 
rangers eager for these bells and whis¬ 
tles is an open question. But Amiga 
does represent another 
step toward making com¬ 
puters easy and convenient 
to use. 

Apple Computer’s Mac¬ 
intosh popularized such 
features as the “mouse”—a 
hand-held pointing device 
used to make commands— 
and screens within screens, 
or “windows,” that display 
more than one application 
at a time. Amiga shares 
these features, while also 
being able to perform more 
than one job simultaneous¬ 
ly, such as writing and 
printing. 

Ease is key. Having a 
computer that is easy to use 
will be crucial in businesses 
as PC’s begin appearing on 
desks of less sophisticated 
users. International Busi¬ 
ness Machines now sells 
Top View, a program that 
permits windows on the 
screen and allows people to 


switch quickly from one application to 
another. 

These features are of little value if 
the applications themselves are so diffi¬ 
cult that only determined people can 
master them. The solution is the intro¬ 
duction of software that incorporates 
artificial intelligence to make comput¬ 
ers respond to commands in plain En¬ 
glish. For example, NaturalLink, made 
by Texas Instruments, lets users get 
stock prices from Dow Jones News / 
Retrieval by simply asking: “What's the 
current quote for ... ?” 

Jerrold Kaplan, chief technologist for 
Lotus Development, foresees programs 
that read electronic messages and set 
priorities on them. To Kaplan, the limit 
of what AI can do is “our imagination— 
not the power of our machines.” 

While PC’s have proved popular in 
businesses, the home market is still 
largely untapped, because people have 
not found enough uses for them. That 
could change. A promising develop¬ 
ment for home computers, called the 
CD-ROM, for compact-disc read-only 
memory, resembles audio compact- 
disc players. Using the same technolo¬ 
gy, it stores vast amounts of text—up to 
100 million words, or 220,000 pages— 
on a disc that can be searched by a 
computer for desired titles, words or 
sets of words. 

The first home applications of the 
CD-ROM are expected this autumn. 
Grolier will sell a disc containing its 9- 
million-word Academic American En¬ 
cyclopedia for $199, one third the 
price of its printed version. Atari plans 
to sell a disc drive to read CD-ROM 


If You Want to 
Buy a Computer... 

More than 300 companies sell 
personal computers. Facing' this 
cornucopia of choices, some pro¬ 
spective computer buyers throw 
up their hands in frustration. 
Fortunately, books about PC’s 
are proliferating, too; there are 
almost 6,000 in print. Here are a 
few that aid first-time buyers— 

■ Computers for Everybody— 
1985 Buyer’s Guide, $19.95, by 
Jerry Willis and Merl Miller, Di¬ 
lithium Press. Overviews of more 
than 100 PC’s, plus ratings on ease 
of use, software availability. 

■ How to Buy Software, $14.95, 
by Alfred Glossbrenner, St. Mar¬ 
tin’s Press. This 648-page book 
tells how and where to buy every¬ 
thing from spreadsheets to games. 

■ The Simon & Schuster Guide 
to Computer Peripherals, $14.95, 
by Linda Gail Christie. All you 
need to know about printers, mo¬ 
dems, monitors, disc drives. 


data, for $500. Next could be CD- 
ROM’s that show graphics and play 
music—perhaps a demonstration of 
Beethoven’s Fifth Symphony to go 
with his biography. 

Homeowner’s aide. PC’s could find a 
place in the home as control devices. 
One company, CyberLynx, sells a pack¬ 
age called Smarthome that lets IBM or 
Apple computers switch on lights or 
§ alarms at specific times—such as when 
3 a small child passes a sensor while leav- 
| ing a play area. The package can turn 
§ on lawn sprinklers, or summon fire en- 
| gines if detectors sense smoke. The 
computer is used to run the system. 

Better teaching tools are in the off¬ 
ing. too. Apple is at work on a class¬ 
room network that iinka a PC on the 
teacher’s desk to those being used by as 
many as 32 pupils. As for educational 
programs that are often little more 
than electronic flashcards, help has ar¬ 
rived. In Robot Odyssey I, a game sold 
by Learning Company, players design 
robots that help them escape from a 
futuristic underground city. Purpose: 
To improve skills in logic. 

All these changes are in answer to 
pleas for machines and programs to 
make PC’s useful for ordinary Ameri¬ 
cans. Says Bill Machrone, editor of PC 
magazine, “There are going to be 
more and more compelling reasons for 
people to start using PC’s.” □

Wll 



The home computer is possibly one of the most important technological 
breakthroughs of the 1980s. Computers are far too important to be misunaerstood as 
they are now an integral part of our everyday life and they will become even more 
important in the future Most businesses use them in one form or another and our 
children are growing up in a society that is very dependant on them. 

The home computer's place in this revolution is most important. For children it is 
an introduction to the terminology used by computers and the many programmes 
available, whether they be simple games or educational, introduce them to the use of 
the equipment at the same time as teaching them new skills - while they are being 
entertained! For adults easy to use programmes make every day tedious chores mucn 
more simple - home budgets, smail business accounts, reference files or dub 
accounts to name a few — and simple programming commands allow you to design 
your own programmes for whatever use you want. 

Computers are easy to use and they only require a power point and TV to set up. 
With many practical uses the home computer can be a very entertaining hobby. 

in response to requests received from the many home computer users who are 
members of the Club we have introduced this addition to our regular record selection 
leaflets. In it we intend to offer a range of software, accessories and wherever possible 
hardware for the machine You use on a regular basis. 

The number of different computers available on the market is large and we do 
not intend to concentrate on any one brand, if your computer by some chance is not 
listed on the pages that follow or if you would like to see specific programmes etc 
included please contact the Club and your request will be noted for future editions. 

As with ail products sold by the Club all of the programmes etc listed are 
guaranteed factory fresh and will be replaced if received by you in a damaged or 
fauity condition. We can however not accept returns for any other reason. 


In this programme we have offered, in the main, games 
programmes. Educational and Instructional programmes will 
follow in later editions. 

Postage and Packing in ail cases is 65c for one cassette plus 
30c for each additional cassette posted at the same time. 

Allow 21-28 days for delivery from date of ordering

Sorting Out 
Confusion 
[n Printers 


By PETER H. LEWIS 


H OW does one choose the 
right printer when there 
are literally scores of new 
models being introduced 
ach year? 

The 1985 models range from bat- 
ery-powered units the size of a aga- 
ette carton to $7,000 laser engines 
bat can turn a personal computer 
ato a professional printing shop. 

In a heroic effort, the writers, tech- 
icians and editors of PC magazine’s 
ept. 17 issue have compiled the best 
nd most comprehensive roundup of 
rinter models introduced or signifi- 


quality), 81,4%. 

^Centronics Printstation 240 (dot 
matrix), 81,495. 

^Toshiba P351 (dot matrix), 81,895. 

^Epson’s SQ 2000 (dot matrix ink 
jet), 82,295. 

qOkidata’s Pacemark 2410 (dot 
matrix), 82,395. 

qQume’s Sprint 11/90 Plus (letter 
quality), 82,500. 

^Apple’s LaserWriter (laser), 
86,995. 

PC’s editor. Bill Machrone, said 
that although they were not listed in 
this roundup, the printers that im¬ 
pressed the reviewers most in last 
year's printer review are still techno¬ 
logically formidable, and that often 
they served as the unofficial stand¬ 
ards against which the newcomers 
were measured. These models, and 
their 1984 prices, included the Hew¬ 
lett-Packard LaserJet (laser, 
83,495); the Centronics GLP (dot ma¬ 
trix, 8299); Toshiba’s 1340 (dot ma¬ 
trix, 8995); Epson’s FX-80 (dot ma¬ 
trix, 8599), and Qume’s Sprint 11/55 
Plus (letter quality, 82395). 


Cardiff’s microcomputer 
translates sound Vfifi 
to crotchets and quavers 


GREAT composers of the 
future should be spared the 
laborious task of writing out 
by hand their crotchets and 
quavers, turning instead to a 
microcomputer electronic pitch 
recognition system just devel¬ 
oped at University College. 
Cardiff. 

The system, consisting of a 
microphone, signal processor 
and graphics software, is 
capable of translating the pitch 
and duration of musical notes 
instantly into standard musical 
staff notation on a micro¬ 
computer screen — and storing 
and playing the notes back as 
required. 

Cardiff University Industry 
Centre, which is dedicated to 
getting product ideas out .of 
the lab and into the market 
place, has established a new 
company, Auditec, to handle 
the system. 

Only two products have been 
developed so far, both for the 


descant recorder.' One 1 
essentially a computer gam 
for young children, - combinin 
the system’s’ note recognitio 
capabilities ' with ’ cartoo 
graphics and a library o 
tunes. The other is a seriou 
descant recorder tutorial prc 
gramme. 

CUIC is also interested i: 
developing the pitch processor’ 
use in industrial and con 
mercial fields, provided it ca 
find a company willing t 
provide research and develop 
ment funding. 

It suggests, for example 
that the processor could b 
packaged as a security devic 
which would allow access onl 
when it recognises.a sequenc 
of notes. '• • 

Equally, it could be geared t 
monitor the performance o 
industrial machinery, by signal] 
ing changes in the pitch of elec 
trical motors. -- 

ROBIN REEVES 


antly redesigned this year — 70 in 
JLThis follows the magazine’s epic 
lav. 27, 1984, issue in which 120 
rinter models were evaluated. (For 
. copy of the Nov. 27 printer review, 
end 86 to Kim Armstrong, Back 
ssues, PC Magazine, Ziff-Davis Pub- 
ishing, 1 Park Avenue, New York, 
f.Y. 10016.) 

The new printers were tested for 
ompatibility with the I.B.M. ex- 
aided ASCII character set; range of 
satures; print enhancements and re¬ 
al ting print samples; speed with and 
rithout special print enhancement 
satures, and noise levels. Dot-matrix 
rinters’ compatibility with dot-ad- 
ressable graphics was also tested; 
lis means that the computer in- 
tructs the printer exactly which v 
ots, of all those on the video screen, 
re to be printed. 


Over aUTthe quality of printers was 
bund to be very impressive. Even so, 
6 of the 70 models were singled out 
>y the editors as “particularly out¬ 
standing”:

matrix, thermal transfer), 8268.

DUTCH PICK 


ATARI has achieved a dram¬ 
atic breakthrough in Europe 
with the news that the Dutch 
government has selected the 
800XL as its recommended 
micro for the country s 
schools. 

The company now predicts 
that this will result in sales of 
100,000 machines to edu¬ 
cational outlets in Holland over 
the next two to three years. 

Atari was given the blessing 


of the Dutch after months of 
negotiations and in the face of 
intense competition from major 
rivals. 

This is now being seen as the 
key to unlock the door to similar 
deals all over Europe. However 
France remains the one country 
where Atari is unlikely to make 
much headway, thanks to the 
chauvinistic attitude of the 
French themselves. 

As part of the Dutch deal the 



800XL - named as Home 
Computer of the Year in the 
British Micro Computing 
Awards 1985 - is now to be 
featured in a television series 
there. 

Breakthrough 


pioneering B8C series. 

"This award is a major 
breakthrough for Atari com¬ 
puters in Holland", says Rob 
Harding, Atari UK sales man¬ 
ager. "It was won in the face of 
formidable competition from 
Philips, the indigenous manu- 


This, according to the com¬ 
pany, is being designed to 
introduce school children in 
Holland to the intricacies of 
computing, similar to the 


facturer. 

"We believe that this will 
lead to the 800XLbecoming the 
leading 8-bit micro in edu¬ 
cation".
