No real desktop is as tidy as that 
represented on the Atari ST. 
Duncan Evans looks at a pack- 
age that simulates the clutter of

notepad, calculator, and sundry 
other executive toys.

Unfortunately they also have the

Spectrum's 


£600 P 


SPECTRUM GROUP is to 
launch a £600 IBM PC clone 
next week, and as Acorn also 
prepares a badged version of 
Olivetti's M19 it looks like be- 
Coming open season lor the 
Amstrad PC. 

The Spectrum machine is a 
Far Eastern import, and sports 
640К Ram, MSDOS and 
GWBasic and twin 52 inch disc 
drives. At the price, and at this 
specification, the Specirum 
machine could beat the 
Amstrad on price, and has the 
added advantage of having the 
IBM standard operating sys- 
lem, MSDOS, bundled 
Amstrad's machine will in- 
stead have DOS Plus, the PC 
operating system from Digital 
Research, included instead 

Acor's version of the 
Olivetti M19 looks like being 
less of a competitor on price 
than the Spectrum PC. Olivetti 
prices the M19 high by today's 
Standards, and although sell- 
ing it through Acorn would give 


it the opportunity to break into 
the UK educational market it's 
unlikely to allow Acorn, its Brit- 
ish subsidiary, to undercut it 
The machine also lacks PC 
standard expansion slots 


Alligata offers

Alligata Software is organising 
a "Prize of Your Dreams" sum- 
mer promotion for its pro-

Alligata tape or disc up to 30 
September should receive an

The form covers current 
stock and Alligata's summer

AMS launches Magazine 
Maker digitiser bundle 


AMS has combined its AMX 
Pagemaker and AMX Video 
digitiser to produce a package 
called AMX Magazine Maker. 
The digitiser allows any video 
that produces a composite sig- 
nal to take images from a cam- 
era or TV. These are then con- 
verted to the Amstrad graphics 
screen, and can be used within 


Pagemaker. The combined 
Packages cost £129.95. The 
complete package can be used 


to produce  magazine-like 
layouts.

New Sinclair Spectrum is 
ready for production

a product of Amstrad's engi- 
neers rather than Sinclair's де- 
sign team. И doesn't use the 
Astron cards Sinclair had 
planned (ог the Pandora, and 
the technology of Loki, Sin- 
clair's advanced version of the 
Spectrum, remains firmly on 
the shelf. 

The machine's interfacing is, 
however, likely to remain a 
problem for Amstrad, as the 
Spectrum 128 has both an 
RS232 and midi, albeit with 


non-standard plugs, while its 
rivals” the Amstrad 484 and 
6128 do not. Alan Sugar main- 
tains that the Plus 2 will not 
signal the death of the 464, but 
it this is to be the case Amstrad 
may be forced to limit the new 
Spectrum's specifications to 
keep it firmly in the games 
market. 

Amstrad's main professed 
interest in Sinclair was for the 
Spectrum's games capability, 
but a games console launch is 
also a possibility. 





AIPOPULAR COMPUTING WEEKLY 











19-25 JUNE 1986 








PCs still pending 
at the Amstrad show 


The latest Amstrad show, held 
at London's Novotel last week, 
sulfered from a severe case of 
PC starvation, As expected the 
‘Amstrad IBM PC compatible 
failed to show. and to make 
matters worse the MSDOS up- 
grade from Vortex appeared to 
have joined it in Limbo. Vortex, 
however, confirms that ils ma- 
chine is ready, and UK distribu- 
tor Screens expects delivery in 
the next eight weeks. Amstrad 
remains mum about its own 
PC, but it appears that some of 
the larger dealers are current- 
ly in negotiation to take deliv- 
ery of the machine, so the 
launch can't be too far off. 
Launches this time round were 
however limited to an Amstrad 
modem, selling at £99.95. This 
is à rebadged version of the 
Pace Nightingale, which retails 
for a sum not unadjacent to 
£99.95 

The upgrade Screens in- 
tends to distribute is produced 
by German manufacturer Vor- 


tex, and is based on the Intel 
8086 processor (the faster ver- 
sion of the 8088 used in IBM's 
РС). It will come with 512K Ram 
and Digital Research's DOS 
Plus operating system bun- 
Фед, and the latter will include 
hooks allowing it to run DR's 
Macintosh-like Gem graphics 
environment. 

Screens isn't willing to fix a 
price for the upgrade until the 
first shipments arrive, but reck- 
ons it will be around £400-500. 
The company also unveiled an 
enhanced version of Vortex's 
expansion board for the 464 — 
this should also arrive ín the 
next couple of months. 

Add-on supplier Timatic had 
been blessed with some new 
arrivals, although spokesman 
Nick Young claimed that the 
hard disc, although ready, had 
blown up twice in prototype the 
other day and therefore 
couldn't be present. He did 
however promise that the non- 
incadescent production ver- 


sions would be very cheap. In 
default of this the company's 
main exhibits were the 
"Bigdisk" duo – one megabyte 
(unformatted) 53 inch discs for 
the 8256 (£209) and 6128 (£249). 
Both of these work in conjunc- 
tion with the company's 
Camelion software program 
that will allow Amstrads to 
read and write MSDOS format 
discs. 

Former Spectrum specialist 
DK Tronics was offering a 
range of Amstrad 464 expan- 
sion devices, including speech 
synthesiser, Ram expansions, 
light pen and 256K silicon disc. 
The latter retails at £99.95, the 
same price as 256K configured 
as Ram 

EMR had a combined hard- 
ware/software music package 
on display. This consists of 
Miditrack Performer software 
and midi interface, the com- 
plete package costing £129.85 
lor 864/6128 version and 
£139.85 for 464. The system is

limp in hot weather 





claimed to work with any midi 
instrument. 

New Star Software's William 
Poe! made a more overt al. 
tempt to enliven proceedings 
by claiming that he would un- 
vell a low-cost PCW8256/8512 
lookalike at the show. Desper- 
ate newshounds reporting to 
the stand were aggrieved to 
discover that the “lookalike 
was a cardboard cut-out mod- 
el, a number of which he'd had 
printed up for the show. 

To prove we can lake a joke 
we'd just like to point out that 
New Star is selling dBase I! at 
£395, while First Software re- 
tails itat £119.95 





Budget game prices 
drop down to 99p 


Budget games manulacturer 
Central Solutions has slashed 
the price of its range to 99р. 
According to a Central spokes- 
man the company is reacting to 
the current stampede into bud- 
get titles, which has seen Fire- 
bird increasing its profile and 
the likes of US Gold and Mikro- 
Gen joining the fray. 

Central's price cut also al- 
fects its ten game packs, which 


were priced at £5.95 and £6.95, 
and are reduced to £4.95 each. 
The company says that it can 
still make a profit on these 
prices, and feels the cuts 
should increase ils market 
share drastically. It intends to 
maintain the low prices, and 
re-released 12 back-to-back 
adventure games tapes at 99p 
each at the beginning of this 
week 





New games house 


Andrew Wright has left 
Activision to form а new com- 
pany, Thalamus, which will be 
the games software arm of 
Newsfield, publisher of Zzap 
and Crash. According to Wright 
Islington-based Thalamus is a 
separate company within the 
Newfield group, and will be 
managed independently. 
Wright intends to release 


four titles by Christmas, one of 
them being a tie-in, and prod- 
ucts, he says, will be of a high 
quality. “You won't ever see us 
producing a £1.99 game, add- 
ing a poster and a sticker and 
putting it out at £9.99, " he says. 
Although he claims to have 
products ready he doesn't in- 
tend to give any details until 
later in the year. 





THE MAN in the photo 15 Vick 


Pearce, developer of the 
Соттіе-Х package for the 
Amstrad PCW. The package 
consists of modem that sup- 
ports Email and viewdata, dual 
serial and Centronics inler- 
face, Comm + software and an 
Easylink subscription form. It 
costs £286.35, and is claimed to 
be incredibly easy to use. But if 
this is the case, why's he trying 
to stick that interface there? 
Telephone engineers should 
phone him on 0992 541118. 


First plans 
expanded range 


First Software and Publishing, 
which recently announced an 
Amstrad PCW8256/512 version 
of Ashton-Tate's dBase || at 
£119.95, is also to sell Ше pro- 
gram on the Commodore 128 
and Tatung Einstein. But ac- 
cording to First boss Sarah 
Galbraith the company has no 
plans to release the program 
‘on the Amstrad PC when It is 
launched 

First has an exclusive UK 
licence from Ashton-Tate to 
market CP/M versions of 
dBase al the current low price, 
but the latter company is highly 
unlikely to be interested in cut- 
ting the cost of its IBM PC 
products. 

First will, however, be 
launching a £49 integrated soft- 
ware package for the PC in the 
summer. this will consist of 
spreadsheet, word processor, 
graphics, time manager, diary 
planner and forecaster, and 
will effectively be a re-issue of 
an integrated suite previously 
marketed by Peachtree

Puzzle No 213 

















































QL in print 


have just bought a 
[s GLP printer 

for my QL. Из an excel- 
lent printer, ideal for the ma- 
chine. For £160 you get trac- 
tor and friction feed, serial 
and parallel interfaces, a 
host of typefaces, a good 
NLQ and complete compati- 
bility with the QL and its 
bundled software (including 
Easel. The ribbon is a Broth- 
er M1009 and Commodore 
MPSB03 type, so is easy to 
obtain. However the state of 
euphoria I'm now in was only 
reached after two printers 
and several wasted days. То 
save others from similar 
frustration | offer the follow- 
ing information: 

There are in fact three ver- 
sions of the GLP with differ- 
ent firmware; the original 
IBM, an EPSON RXBO equiv- 
alent and the QL version. 
The manual with each is for 
the IBM version and in my 
case no extra information 
was given about the changes 
in the others, 

И you use а centronics 
interface you should be able 
to use any of the variants. 
The problem arises from the 
QL's need for a &-bit and no 
parity serial setting not рго- 
vided on the IBM version 

The QL version's cha 
ter set one is 100% compati- 
ble with the QL and codes 
above 192 (decimal) are non- 











discovered that it had only 16K. 
ol memory, so | spent £3.60 on 
postage and returned it to 
Sinclair 

Two weeks later my comput- 
er was returned, but this time 
when | switched it on the 
Screen remained blank and re- 
fused to display the copyright 













printing. Character set two 
repeats above 127 The DIL 
switches are slightly differ- 
ent as follows: 








The Epson version has in- 
ternational character sels 
and an italic typeface. The 
switch settings are com- 
pletely different and | can't 
offer much advice on this. 
Switch 2-2 is the МО switch 
and the communications 
switches are possibly as 
above. 

Micro Anvika, ol Totten- 
ham Court Road, London, 
sold me the printer with the 
switches set for the OL and a 
phone call to Centronics re- 
vealed the switch functions. 
My only criticisms of an 
otherwise perfect accompa- 
niment to the OL are, apart 
from the terrible documenta- 
tion, that thick single sheet 
paper gets caught on the lid 
which necessitates its Ire- 
quent removal. Also the ех: 
tra QL characters do nol 
print in NLO, rather they ap- 
pear as emphasized. Graph- 
ics characters or an italic 
mode could surely have 
been added to the QL 
version

rangle. Unfortunately, due to his absent-mind- 

edness, he has mislaid the paper on which he 

had written the details required. 

However, he does remember the following 

(i) The quadrangle, which is nearly but not 
exactly square, is rectangular in shape 

Ui) The length and width are both an exact 

number of feet, and the area (in square leet) is a 

five-digit number ending with a 4 

(ili) This five-digit number contains within it a 
run of three consecutive digits in ascending 
numerical order. 






What is the smallest that the quadrangle can 
be? (Note that by ‘almost square’ we mean that 
the longer side is no greater than 10% more 
than the smaller).

Hardware: Review 











the original kernal, a copy of which is 


Гай the problems inherent in the 


High speed 
the one which causes most angst is 


certainly the speed of the disc drive. The 
1541, while reliable and "intelligent", uses 
а serial system which is designed lor 
economy rather than speed. As a result, 
Commodore 64 owners tend to go pale 
when they see the speed of, say, BBC disc 
systems. 

There have been many attempts to 
speed up the Commodore DOS, ranging 


stored in the Rom. 

Installation is straightforward апа 
should present no problems. The toggle 
switch can be mounted permanently, or 
lett protruding from the cassette port. Syn- 
tax for all routines is largely similar to 
slandard syntax; in many cases abbreviat- 
ed. However, there are some useful addi- 
tions; Гог instance, on saving, the Cock- 
roach Rom checks to see whether there is. 
sufficient space on the disc to save the 
program first, rather than just ploughing 
ahead and coming up with an error mes- 
sage И it runs out of blocks. 

The Save With Replace problem, which 


trom cartridge-based operating systems 
such as Quick-Disc, to software packages 
which require you to produce "fast-load'" 
back-up copies of your software. One of 
the latest attempts is the Cockroach Turbo- 
Rom. 

Cockroach's previous attempt to speed 
up CBM disc operations was a software- 
based system. This idea consists ol a 
single 8517 Rom chip in a socket, attached 
to a toggle switch. Fitted instead of the 
normal CBM 64 or SX-64 kernal, it claims 
to be able to speed up loading, saving and 
verifying times by a factor of five. There's a 
price to pay for the extra routines; all the 
cassette and RS-232 code has to be left out 
to allow space for the new kernal. Fortu- 
nately, the toggle switch allows you to 
switch off the Cockroach Rom and return to 








has been the subject to great debate within 
the user groups, has also been circum- 
vented - the Cockroach Rom always 
scratches old files before saving new ones 
in the same name. There's also a screen 
dump feature, although this is disabled it 
hi-res or multicolour screens are being 
used, 

Lastly, thé Turbo-Rom contains many 
disc utility features which are familiar trom 
utility cartridges such as The Final Car- 
tridge and Robtek's Turbo; read disc error 
channel, display directory, intialise disc, 
validate disc, rename Ше, fast format and 
во оп. Most of these commands are single 
characters preceeded by an ampersand. 
For heavy disc users, or multiple disc- 
drive owners who wish to renumber de- 
vices without making hardware changes, 
the Turbo-Rom would seem a worthwhile 
idea. Since it can be switched off al any 
time, there's по worry that it will interfere 
with your software (although apparently 
some programs, such as Easy Script, have 
loading routines which are incompatible 
with the Turbo-Rom), Well worth 
considering.

function accessory lor 


use on the GEM desktop. Writ- 
ten by the American company 
MichTron, it has been pub- 
lished in the UK by Microdeal 
and retails at £29.95. 

There are eight accessories 
available although the value of 
four of them is open to ques- 
tion, What you get for your 30 
quid then, is an Ascii table, 
calculator, notepad, dialler and 
phone log, sliding block puz-

In order to utilise Corner-

Printouts can be handled as

be stuck together. 

The software is very simple 
to use. You either select the

fingered selections) or direct 
operations with a series of two- 
letter mnemonics.

desktop accessories. И you 
have a 520ST and TOS is still 
on disc then don't bother to buy 
Cornerman as there isn't 
‘enough memory left to run any- 
thing but the smallest of 
programs. 

The Ascii tale simply gives a 
list of the ST character set plus 
codes, This is, of course, just 
what you'd buy a desktop pro- 
gram for. 

Equally worthless are the 
Clock feature and the sliding 
block puzzle. The DOS window 
function allows you to exit GEM 
temporarily and call up a pro- 
gram for manipulating TOS 
before returning to the GEM 
system 


The calculator is useful, 





done, at present, with the 
cursor keys or а joystick. You 
can create your design on any 
or all of eight layers which can 
be thought of as transparent 
overlays to be added or re- 
moved from the work in 
progress. 

This allows you to build-up a 
design in stages. Print-outs can 
selectively include or ignore 
various layers. 

Other features include pan-

work in decimal, binary, octal 
and Hexadecimal. Upon these 
numbers you can рейогт 
Boolean logic if you so desire, 
as well as displaying word val- 
ues (16 bit), double and quad 
word values. 

The notepad accessory en- 
ables you to store short notes, 
along with time and date, on 
disc for later reference.

At present TechniQL has

‘support 3D graphics and trans-

While this sort of output is 
fine for certain applications, 
serious users will almost cer- 
tainly want output to a plotter, 
and input by keyboard or joy- 
stick leaves a lot to be desired. 
Therefore support for a mouse 
or graphics tablet would be 
welcome. 

Talent is aware of these 
problems, and is promising 
continued development of the 
package to cover these areas. 

So who will use TechniQL?

to deal with the UK telephone

This makes it completely 
useless, Microdeal is now 
looking into this, but don't hold 
your breath lor a possible 
conversion. 

As the program stands in its 
current format, in essence 
you're paying £30 for a calcula-

Through the jungle 


Richard Hare examines the friendly, fervent atmosphere of Compunet 


Small percentage of Commodore 64 

Owners have access to, or have even 
seen the Compunet database. 

Those that do have the Compunet 
modem have experienced some of the 
benefits: talking to fellow users; discount 
prices on major software houses’ pro- 
grams; a cornucopia of free user software 
music and graphics plus the opportunity to 
market your own programs on Cnet 

Compunet is rare among British 
databases, since the greater part of its 
content is created by the users 
themselves. 

The network can basically be divided 
into two areas: the first section comprises. 
mainly of commercial and Compunet's 
official software, the Compunet editorial, 
MUD and so on. The other area is reserved 
for programs, graphics, music, clubs, gos- 
sip columns, elc, put up on to the system 
by users via their modems. Aplly named 
"The Jungle”, this section covers a vast 
area of Compunet and it would take you 
the best part of the day to go through it all 


Exciting aspect 

Constant change is an exciting aspect of 
The Jungle and there is something new to 
see every day. The quality of The Jungle 
material is remarkably high and it is quite 
stunning how many talented program- 
mers, graphic artists and musicians there 
are on Cnet. Just recently two 'netters, aka 
Stoat and Tim, programmed an animated 
representation of a concert to accompany 
the tune from Firebird's game Thrust, with 
full co-operation trom the composer, Rob 
Hubbard (Rob is a Cnet subscriber and all 
of his music is available on the system free 
of charge) 


| tis a strange and sorry fact that only a 


Sport Aid 


Uploading a freebie like Stoat and Tim's 
may seem a pointless exercise, but this 
could not be further from the truth. Apart 
{rom improving your standards in which- 
ever field of computing you may pursue, 


uploading your work on to the ‘net could 
result in your talent being realised by 
thousands around Britain, including per- 
haps several software houses. 

This is exactly what happened to Bob 
Stevenson (LD. RS4) and Doug Hare 
(МАСНВ1) who have both uploaded graph- 
ics and programs on to Cnet and as а 
result a lot of their work has graced the 
pages of various magazines, Recently 
they have been working with Activision on 
а new project and several other compa- 
nies are interested in signing them up to 
write software. 


Electronic mail 

Working as a team, Doug and Bob have 
now adopted the business name Kinetic 
Design. although many refer to them as 
Jocksoft owing to their Scottish origins! 
Communicating with other people is one of 






Jane's Place. 


the most rewarding aspects of Compunet. 
One method of contacting another user is 
simply to send them a message with the 
mailing facility. Once you have typed your 
letter using the inbuilt editor program (low 
resolution graphics may be included) you 
can send off your 
message to another 
user which they re- 
ceive instantly. The 
amount of mail you 
receive usually var- 
les directly to the 
number of people 
you get to know on 
Cnet, so your mail- 
box is likely to be а 
bit empty during the 
initial days. 

When you connect 
to Cnet a small pillar 
box indicates that 
you have mail and И! 
you receive mail 
while on line you are 
informed of this at 
the top of the current directory you are оп 
Compunet mail is always a welcoming 
sight when you log-on (perhaps because 
you know it won't be a bill), especially so 
оп your birthday, ог at Christmas when 





you may receive a few electronic greeting 
cards! 

However, communication between us- 
ers need not be limited to mail correspon- 


Thrust by Stoat and Tim 


dence. At a recent Commodore show held 
at the Novotel, crowds of interested people 
surrounded the Compunet stand. The peo- 
ple who visited the stand would probably 
have seen Cnet's new scrolling chat sys- 
tem, Party-Line. Basically Parly-Line en- 
ables you to converse with several users 
ata time. 


Team spirit 

Chatting on Party-Line is very similar to 
using a CB Audio and indeed many users. 
have adopted a special dialect whilst 
speaking on Party-Line! Late night/early 
morning chats are usually crowded and at 


Jungle Eye by Rob Stevenson 


around half past one a few weeks ago Jeff 
Yakus" Minter, Tony “Ratt” Crowther 

and Archer (no alias) MacLean were 

among the people chatting on Party-Line. 

Party-Line is a very fast system which is 
well presented and incorporates several 
useful commands. Its predecessor, Chat- 
On-Line, is slower to use, but can still be a 
hive of activity when it picks up the pace. 

In this article I've tried to give a brief 
insight into a tew aspects of Compunet 
which | particularly enjoy. 

1 think, however, that Cnet's greatest 
strength is the team spirit, which always 
seems to be present — а sort of friendly, 
fervent atmosphere.

Addictive romp 


astertronic are really 
coming up with some 
good software now, 


and Richard Darling, author of 
the latest offering Master of 
Magic, has come up with an- 
other pleasant surprise 

Your character has been 
dragged beneath the surface of 
a dark pool by the hand of 
Thelric, the M of M, who 
plunges you into a strange 
mystical world of Magic and 
Evil. Ho-hum, another Sunday 
afternoon in the country! But he 
has plunged you because he 
wants you, yes you, to retrieve 
the lost Amulet of Immortality 
no less, But all this is just 
window-dressing for the game 
proper, which involves your 


character in plenty of monster- 
bashing and scroll- and potion- 
getting 

The screen is divided into 
four main windows. At screen 
top-left is a very small plan- 
view of your immediate sur- 
roundings, a line-of-sight view 
that opens out realistically as 
you round a corner or enter a 
room to show the inhabitants 
or objects. At the bottom of the 
screen is an information win- 
dow showing a graphic repre- 
sentation of the monster at the 
current location as well as oth- 
er details such as adjacent 
doors and staircases. These 
graphics are very colourtul and 
detailed, which is just as well 
as those in the plan-view are

You play the part of a little

оп а long quest in search of the 
Elixir of Life — however, to stop 
the noble fellow from complet- 
ing his task is a selection of 
assorted nasties. 

If you are a Dungeons and

at home with this game, as it 
has a similar feel, Your status

attributes, with the most impor- 
tant being Endurance; when 
this reaches zero, you've had it! 

You move from screen to

Disaster to disaster 


iter Ego, the male ver- 
sion, proved curiously 
compulsive in the Popu- 


Jar office a couple of weeks 
back. Now Activision has re 
leased the female version and 
it's having the same effect. 

Alter Ego is one of the 
Activision ‘oddball’ releases. 
You get to choose a personal- 
ity. and then ‘live’ it through 
seven stages of life from baby- 
hood to old age. By choosing 
‘experiences’ from a series of 
on-screen icons, and reacting 
to them in a number of different 
ways, the program analyses 
your personality and charts 
your progress through li 

The female version uses 
many of the scenarios from its 
male counterpart (some slight- 
ly adapted) so is not substan- 
tially different. But at least it 
doesn't assume you're going to 
spend your life tied to the kitch- 
en sink. 

The program probably ap- 
peals most to the egomaniac 
side of one's nature. Getting 
the chance to do all the things 
you wouldn't in real life - writ- 
ing a novel, marrying eight 








times, skipping school and all 
sorts of wild sexual experi 
ences (Ihe program carries a 
parental warning notice) — is 
not only huge fun, but also 
seems to bring out Ihe rebel- 
lious streak in everyone play- 
ing it 
There is a generous helping 
of (very American) humour 
running through the game, but 
don't expect your ‘life’ to be all 
happiness and derring-do. 
Much of what happens will de- 
pend on how your personality 
has shaped according to the 
program in previous stages: 
my latest ‘life’ lurched from 
disaster to disaster. Widowed 
at an early age, my adopted 
children inexplicably disap- 
peared in the disc changeover 
from stage six to stage seven, 
and 1 died a cocaine addict and 
alcoholic.

Games: Arcade Action 








short while ago Artic released 

CPC machines, Obsidian and Alad- 
din's Cave, unusual in that for once they 
weren't just conversions of established 
Spectrum games, but actually made an 
attempt to exploit the features of the 
Amstrad 

Of the two the most successful to my 
mind was Obsidian ~ the gameplay was 
challenging with fast action, devious puz- 
2105 to complement your reflex skills and 
the graphics were excellent. Set in а space 
age craft, a clever combination of colours 
and design created an almost 30 metallic 
quality that only Virgin's Strangeloop and 
Mikro-Gen's Equinox have been able to 
match 

Aladdin's Cave was more standard fare, 
principally just a platiorm game of few 
locations. However И. did have one or two 
intriguing qualities and new touches that 
made it enjoyable and | lound myself 
returning many times for another go. One 
particularly novel feature is that your char- 
acter has the power to be able to change 
into a variety of different beasts in order to 
best tackle the obstacles presented, Now, 
after a decent interval of time, I feel it 
would not be unfair to release the tips for 
this one. 

There are five characters that you can 
assume in all. Only the Man shape can be 
used to collect objects, only the Monkey 
shape can climb poles, the Parrot can fly, 
the Dolphin can swim and the Genie can 
float left or right. 

You automatically turn into the Dolphin 
when in water, but the other characters 
are selected by pressing the Down and 
Jump keys simultaneously. Up and Jump 
together will turn you back into a man. 

The games rooms are laid out as follows 
for those of you who wish lo make a map: 
Menagerie - where you must collect fruit 
for the monkey. Exits are to the top right for 
the Chandlers room and bottom right to the 
Technocave. 

Chandlers — collect fish for the Dolphin.

Сатез: Адуещиге Согпег 











couple of weeks ago, we saw 

A оте Commodore programs which 

were set around beaches or the 
sea. Probably the most fruitful area for 
adventure plots, though, is а little higher 
up in space, and after that introduction, it's 
по coincidence that the programs we're 
going to look at this week are space 
operas 

Mike Burley is the sum of the brains 
behind Starcrash Software Systems, 
whose first ‘Survival Simulation’ for the 
Spectrum is now ready for your delight. 
Starcrash is Quilf'd and text-only, but the 
təxt is, says the press release: "So rich 
that it comes as close as it possibly can to 
being an interactive novel, where the 
reader's immersion in the atmosphere and 

volvement in the situations which arise 
will give a sense of ‘on the edge of your 
seat’ participation’ 

Mike tells me that the adventure has 
taken 18 months to come to fruition: while 
the text is very loquacious (not necessarily 
the sign of a great novel), careless mis- 
takes In spelling and grammar occur on 
just about every screen, and these detract 
a little from the overall impression. If 
you're thinking of writing an adventure. 
please take а little care over punctuation 
and spelling — such an easily-checked 
thing can make all the difference to an 
adventure and put the player in a receptive 
frame of mind. 

Loading is accomplished via the "LOAD 
CODE" command (I spent half an hour just 
looking for that long-neglected "CODE 
key), but this belies the fact that the 
simulation (lor this is what Mike calls his 
adventure) is Quilf'd. А very well-known 
title-soreen (black and white) leads us to 
the first part of the game and the first 
screen of text "You awake, the acrid 
stench of burning insulation heavy about 
you. Showers of incandescance spit and 
plume in hazy, out of focus flurries of 
glowing, sparking snowllakes. Ever so 
slowly, painfully. Fuzzy memories flit elu- 
sively through the concussed synapses of 
your well shaken brain cells . . ." And on 
and on, for another two full screens. But at 
the end of it all comes the well-known 
phrase or saying, "| await your com- 
mand’, and it's back to Quil-and to try to 
match words and phrases with those in the 
computer's memory. 

Starcrash is, as \'ve pointed out, 








as

much a simulation of survival on а space- 
going vessel (in this case, the crashed 
Lady Angela) as itis an adventure, and this 
means that descriptions go into great de- 
tail in an attempt to create a tangible 
atmosphere. Most of the time this is suc- 
cessful, though the player is required to 
wade through reams of rather purple (and 
not very well зрей-спескей) prose. It's all 
very hi-tech while aboard your crashed 
spaceship, but once outside, you'll find 
yourself in “Impenetrable Jungle, adven- 
turers for the use of, Mk I 


Juggling in the jungle 

Getting out of the wreck is nicely done, 
being accomplished in a couple of ways, 
only one of which is the optimum method. 
As you can only carry four items at a time, 
there's quite a lot of juggling involved in 
getting the objects to their required posi- 
tion: once out of the ship, it proves difficult 
to get back in, so you must SEARCH and 
EXAMINE every location thoroughly. 

The Jungle is pretty hostile, and death 
looms at every corner, just waiting for the 
unwary adventurer. 

Starcrash is in two parts, the completion 
ol the first part yielding a password to the 








more difficult second, so there's a lot of 
adventure to be played. In his location and 
object descriptions, Mike has used a lot of 
imagination and lifted the general tone of 
the game far above the usual Quill'd effort 
- there's a wonderful moment beneath the 
Lady Angela when the "carnage produced 
by the meeting of ship and jungle, jagged 
saw blades of metal and wood spear at you 
from every point of the compass” 

‘Surrounded by the humid jungle, silence 
unbroken except for the dripping of mois- 
ture and the inexorable march of deadly 
killer ants, you are put in mind of the 
oppressive atmosphere of Allen (and. 
strangely, Thunderbirds, though that se- 
ries was по! exactly a horror-house). 

So there's a lot of adventuring to be 
done here, and the price of just £4.95 
makes the program almost mandatory fare. 
for Spectrum owners (and versions for 
other machines might be a good idea for 
the future, Mike).

Games: Adventure Corner 





Computing. This one concerns your el- 
forts, as the sole saviour of the human 
race, to plant the Omega bomb in the 
required position to knock the comet off- 
course, thus missing the Earth. 

That's the scenario, and the game is 
typical Quiifd stuff: very terse descrip- 
tions, sharply-drawn graphics, a few 
sound effects courtesy of The Patch, word- 
matching and so on. On the first screen 
appear three differently-coloured buttons, 
each of which has a different effect, and it 
doesn't take much for even the most nov- 
ice adventurer to work out how to reveal 
the secret objects. Almost straight away, 
the usual Quill-hunger comes into play 
(why? it's been done a zillion times before, 
and it's all getting a bit b-o-r-i-n-g now 
please, no more hunger scenarios!) 

1 found it all a bit of а pain in the ВХХ; 
atter the first few locations, one gels the 
feeling that what is to come is just more of 
the same. Although | would be the lirst to 
champion the Quill and the sterling work it 
has done in getting the efforts of non- 
programming adventure writers to the at- 
tention of the general public, nevertheless, 
Оийга adventures can become awfully 
boring sometimes, and one longs for the 
flexible approach of, for example, Infocom 

Although Rogue Comet has been well 
reviewed in other circles, | find the asking 
price of £4.95 just too much. When there 
are programs like Knight Tyme, Spell- 


bound, Seabase Delta and do on all avail- 
able al just £2 or £3, it's about time that 
prices were re-thought and re-adjusted

Show. Qor is the name of a planet, founded 
by rich space pirates and "the ruling 
classes”. Eventually, the pirates ousted 
the nobles, one of whose exiled number. 
Zaucu, is returning to the planet, bent on 
revenge. You, as Jo, a special agent of the 
Supreme Universe Command, must ac- 
company him and turn the situation to your 
own advantage. The background scenario 
is very confused, with vague hints of vast 
empires in space in the manner of many 
SF authors ol the 50s and 60s. 


Lost in space 

Maltdale has, unfortunately, missed the 
opportunity to present Jo, like Level 9's 
Kim, as an androgyne — he's very firmly 
referred to as male. 

The storyline proceeds quite well: start- 
ing on board the space vessel, you have a 
limited number of moves before it lands, 
and you must then explore the landscape 
ot Qor. The graphics are very well drawn, 


hi-tech when on the ship, pastoral on Qor, 
and eerie when that is required. But the 
graphics and story are all that | find 
interesting in this adventure: GAC, even 
more than The Quill, has to be very care- 
fully programmed, and author Steve Baker 
has left many errors untrapped. Screen 
layout is very haphazard, and essential 
commands such as Help and Examine are 
not recognised. A very idiosyncratic ter- 
minology is used throughout - what to 
make of this gem of a location description, 
for example: along the main cabin 
corridor to these o and a dead end 
These what? and the "o" is used along 
with abbreviations like "mo" and "tho'" 
as well as newly-invented words like "zao- 
zoom" and awlully feeble in-jokes ("Why 
is this called the Galley, there aren't апу 
Gals here" being one о! the more outra- 
geous attempts) to batter the player into 
bewilderment 

An ами lot of work needs to be done on 
this one belore | could recommend you to 
invest in it; | don't have a price for Qor, 
though I'm sure that it will be too much, 
whatever it is. 

May | ask software companies to please 
play-test your programs thoroughly (not 
just ask the kids next door to have a look) 
before asking the public to part with their 
hard-earned cash?

PETER WORLOCK EXAMINES THE DESKTOP 
PUBLISHING CONCEPT: PUTTING YOUR PRINTER 


TO WORK PRODUCING YOUR OWN "MAGAZINES" 





sktop publishing is the buzz phrase of 
the year in computing circles. And it's 
odd that such a booming subject should 
owe its success to Apple's Macintosh — 
hardly the world's most popular computer 

The idea of using a personal computer to 
create magazines, brochures, reports, 
with the 
Software programs that allowed you to 
graphics and different sizes of text have 
been around for years. The Macintosh made 
the breakthrough by being the first micro 
to offer different text sizes and styles, 
together with high-resolution graphics, as 
standard features of the machine. In other 
words, it was a natural for desktop 
publishing. 

But it required another breakthrough of 
sorts to allow the boom to start. It came in 
the form of Apple's Laserwriter, arguably 
the best computer printer available. What 
makes the Laserwriter so great (apart from 
the £5,000 price tag) is the fact that it is a 
powerful computer in its own right, with a 
68000 processor, 500k of Rom and 15 
megabytes of Ram, and it can produce up to 
eight pages a minute with a resolution of

Laserwriter can produce pages that look 
very much like those in commercially 
produced magazines. But even without the 
Laserwriter, the Mac remains the best 
desktop publisher around. There are 
currently three programs available — 
Macpublisher, the cheapest at under £100; 
ReadySetGo, at about £120; and Pagemaker 
for about £400. As you go up the price 
range the programs become easier/faster/ 
more flexible. 

‘The examples shown here were created 
with ReadySetGo and printed on the Apple 
Imagewriter, a dot-matrix printer. A sample 
Laserwriter page is included for comparison. 




















Although you don’t need to buy a 
Laserwriter (you can send your discs to а 
printer who will output your work on to a 
Laserwriter — much cheaper), 
the Macintosh desktop. 
publishing system is beyond 
the means of most readers. 
However, the Mac's features. 
will gradually become available 
on other computers ~ the Atari 
ST is a good bet. When that 
happens we can all become 
publishing tycoons. 

In the meantime, publishing 
packages for the more familiar 
home computers continue to 
appear. The best-known so far 
are Fleet Street Editor from 
Mirrosoft, and Pagemaker from 
AMS, designed for use with the 
AMX mouse. 

Both packages are available 
at the moment only for the 
BBC B, but both will be. 











supplement 


The ring-bound 
manual is divided 
into sections. 
covering the. 
different 








departments, and 
includes a section 
оп printing methods 
which gives you 
some ideas of the 
problems faced by 
journalists and 











printer in the days 
before 
computerisation! 
The Graphics 
Library section is a 
file of images which 
can be used on your 
page. There are 











around 400 images, 
including 
illustrations, 
symbols and 
cartoons, and a selection of “fancy” 
alphabets which can be used to create 
“banner” headlines. Sports, computers, 
music, maps, heraldry, caricatures, animals, 
astrological signs and Christmas images are 
just a few of the subjects covered, and there 
are further library disks planned. 


Panels 

Panels from the graphics library are 
loaded into the Studio section of the 
program, where they can be edited to your 
taste. Alternatively, you can create your own 
graphics from scratch, using several Реп, 
Ink, Brush, Copy, Reflect, Reverse, Enlarge, 
Reduce, Fill, Rubber-banding and Align 
functions. It's very similar to conventional 








justification and word-wrapping options, 
Page Make-up is the next section, where 
you pull all the text and graphics panels 
you have created into one display area, and 
space them out as you want them to appear 
on the page. In the Preview and Print 
department, you can examine the finished 
page and send it to the 
The final department, Administration, is 
not, as you may suspect from the title an 
excuse to put your feet up and have а cup 
of tea, but the area in which disk 
formatting, graphics mode transfer, printer 
drivers and other utilities are dealt with. 
Don't forget, though, that with Fleet 
Street Editor, and other publishing 
packages, the story doesn't really end when 
you have produced your finished document, 
For a start, it takes around ten minutes to 














produce a page of finished 
print at the highest possible 
resolution, so the idea of 
running off several hundred 
copies is a bit daunting. Better 
by far to use a photocopier. 
Various useful tips on 
photocopying, as 
lithography, stencil and 
binding are included in the 
Fleet Street Editor manual 





Concept 

Fleet Street Editor is the 
first of what will be several 
desk-top publishing packages 
for home micros. This article 
has been intended to give you 
some idea what the concept is 
about, rather than to review 





available for the Amstrad from 
July, and Fleet Street for the Atari 520 ST 
from August, and PCW 8256 from October. 
Fleet Street Editor is described as “the 
first of a new generation of one-step 
publishing packages”. Divided into six 
different sections — studio, graphics library, 
copydesk, page make-up, preview and 
administration — Fleet Street Editor is 
designed to reflect the method by which 
real papers are put together.

art packages, but without the colour 
functions. 

After creating your images with graphics. 
and large text, you go to the Copydesk to 
enter your "body copy". The Copydesk is а 
simple wordprocessor, which can use View 
or Wordwise files. There are four single- 
height and six double-height fonts 
available. After defining your text area you 
can enter text using a variety of 


particular programs in depth. 

‘The best way to learn about 
desktop publishing is to try it for yourself — 
like the computer 
printer itself, 
you have to 
experience what it 
can do for you 
before all the

E рот. Jenkins 





Look out for the laser 


Wk dot-matrix and thermal printers 
have become so cheap that few 
computer users are unable to afford them, 
business users can enjoy the benefits of 
much more powerful and sophisticated 
machines. These include daisywheel printers 
which offer very high quality and 
interchangeable type-faces, and, at the top 
end of the market, the laser printer. But is 
it possible that the price of laser technology 
will come down to home user levels? 


Apple 
Laser printer technology is perhaps most 
familiar through machines such as the 
Apple LaserWriter, which, in combination 
with the MacIntosh, forms a complete 
"desktop publishing"system. Indeed, Apple 
would claim to have invented the whole 
desktop publishing concept. 

However, the Mac/LaserWrite system still 
costs around £7,000, so the facilities it 
offers are not really available to the 
amateur. Paul Smith, MD of Electronic 
Printing Systems, thinks that this might 
change soon. 

EPS is in the forefront of laser printer 
technology, and Paul Smith is well aware of 
the possibilities of the “budget” market. At 
the moment EPS sells hardware and 
software to a market composed of about 
25% mainframe users, and 75% PC users. A 
typical product is the EPS 1000, which at 
£4,995 is within the price-bracket of most 





IvIPOPULAR COMPUTING WEEKLY 


medium-sized companies with heavy 
Photocopy, printing requirements. 

Yes, that read PHOTOCOPY — because 
the laser printer is based on photocopier 
technology, and the EPS 1000 will function 
as a photocopier as well as a printer. The 
EPS 1000 is a highly-volume desktop 
machine. In the laser printer market this 
means a 10 page per minute device, about 
the same size (and physically similar to) а 
photocopier, at 27 x 21 x 10 inches. 

The EPS 1000 offers RS-232 and 
Centronics interfaces, and so can used with 
most popular PC's including IBM, Wang, 
DEC, TI, HP and so on. It features landscape 
or portrait printing, margin set, tab, 
alternative fonts, shadowprint, underline, 
justification, variable line spacing, subscript 
and superscript, line drawing, and a 
resolution of 300 dots per inch horizontal 
and vertical. 


Silence 

Until you have seen the output of a laser 
printer you cannot really imagine how 
much better it can be than the product of 
even the best daisywheel. The added 
advantage of laser, of course, is that it can 
mix fonts, combine text and graphics, print 
up to around 48 point-size text, and, not 
least, operate in almost total silence! 

At the moment EPS's Paul Smith can 
only see one major obstacle to this sort of 
technology coming within the home-user 


price range. “The laser printer is based on 
much the same technology as the 
photocopier, and photocopiers have not 
dropped below 4600-£700 because of the 
basic cost of the ‘engine’. The price of this 
is stuck at around $900, and until there's an 
OEM (Original Equipment Manufacturer) 
who can offer the ‘engine’ (the actual laser 
device to which the manufacturer adds the 
RAM, ROM and operating system) at a lower 
price, laser printers will be high-priced.” 

This situation is, hopefully, going to 
change when the demand for better quality 
printers makes high-volume sales of laser 
printers economical. 





Volume 
Paul Smith predicts that within two to 
three years we may see laser printers at 
around £1,200-£1,300 which will produce 4 
pages per minute, and will beat the quality 
of the present-day inkjet devices such as the 
sub-£1,000 Hewlett Packard Thinkjet, 
which can offer colour facilities, but cannot 
Caste di speed or resolution with the 





Perhaps we will see some high-volume 
sales outlets — such as, perhaps, Amstrad — 
adopting the concept of laser printing 
within the next couple of years. If so, it may 
not be long before the current crop of 
noisy, inky, tardy printers are replaced by 
silent, speedy, powerful printers at 
affordable prices. 4

Printer plotting 


f your greatest worry is that the cost of 





bringing your company to its kn 
а solution which — though it sounds 
expensive — should be a worthwhile 
investment. 

The Inker, from Applied Technology, can. 
save businesses a packet simply by re-inking 
old fabric ribbons. The idea is based on the 
fact that fabric ribbons run out of ink long 
before they are too worn to use — but 
hammering an ink-starved ribbon is the 
quickest way to wear it out. 





YA 





Applied Technology is the UK distributor 
of the American Inker, and the company's 
own offices use the product to save à 
fortune on ribbons. The Inker consists of an 
ink reservoir and a drive shaft, with a 
mounting adaptor which can be chosen to 
cope with all kinds of ribbons; Epson, 
Olivetti, Hewlett/Packard, DEC and so on. 
The savings which can be made in offices 
which might have anything up to twenty 
printers are astounding — one Health 
Service branch apparently managed to save 





f you need new ideas on how to use 

your printer, and a useful reference 
guide to control codes and word 
processing, you might like to look out 
for Getting the most from your Printer 
by J W Penfold. 

Published by 
Babani, this 84 
page bookette 
costs £2.95, and is 
aimed at owners 
of all the popular 
home computers 
and printers. 
Sections include 
an explanation of 
ASCII, control 
codes, sending 
codes to the 
printer, dealing with features such as 
bold and emphasised printing, line 
feeding, density modes and so on. 

The section on word processors covers 
some popular packages such as Quill and 
Visawrite. 4

£11,000 per year by using The Inker. 

‘An added advantage is that Applied 
Technology can supply blank ribbons, and 
coloured inks in five varieties, so that you 
can customise your printer output to suit 
your needs. 

Only really heavy printer users are likely 
to find The Inker profitable, since it costs 
£195 + VAT. But for businesses which 
spend a fortune on replacing ribbons which 
could well serve for years, The Inker 
represents a clever money-saving method. 4

FT om your printer to a whole new 
application with the Underware 
‘Transfer Ribbon from Banbury Bu 
Computers. If you are fed up with listings, 
bored with word processing and tired of art 
packages, how about making T-shirts? 








‘The Underware Transfer Ribbon, 
developed by the American Diversions Corp, 
allows design to be printed out an normal 
printer paper, then ironed down on to a T- 
shirt. At the moment the Epson version 
only is available, but Banbury are hoping to 
make Canon, Kaga, and other makes 
available. 

Any screen image, using hi-res, low-res or 
text, can be prepared on your machine, then 
flipped over to produce a mirror-image for 
printing (if you have appropriate art 
software). The design is then ironed onto 
the shirt — polyester works best, while 100% 
cotton shirts tend to provide a less 
washable image. 

The black only ribbon costs £12, while 
for £19 you can get a set of coloured pens 
using the same special ink, to hand-colour 
your screen dumped design. 

For quick, cheap, "disposable" T-shirt 
designs for events such as shows, sports 
days, open days, or whatever, the Underware 
Transfer system seems to Бе another 
ingenious application for the humble home 
computer and printer. 4.

NEW IDEAS FOR MAKING 
THE MOST OF YOUR 
COMPUTER PRINTING SYSTEM 





sers of the Amstrad PCW machines, 

who require more facilities than those 
provided by the printer supplied with the 
system, will be interested in two bundling 
deals offered by Wilding's. 





‘The Amstrad PCW 8256 is being offered 
with either a Brother НКТО, or a Silver 
Reed EXPD 500 daisywheel printer. The 
printers cost £199.95, while the cables 
and driving software, which includes New 
Star's New Word processor and a spelling 
checker, costs £149.95. Both the printers 
are standard Centronics devices, and the 
prices include VAT. 4

f space is at a premium in your home 

computer set-up, one thing you can do 
without is the problem of where to put a 
stack of printer paper. 

Now PW Engineering has come up with 
paper management system which solves 
most of the problems in one go 

The hardware is produced in sturdy sheet 
steel, finished in beige acrylic = particularly 
suited to the ВВС computer for which the 
system was first designed. It consists of a 








base plate on which the printer sits at an 
angle designed to allow the user to examine 
the print-out as it appears, a set of legs and 
a removable rear paper tray. 

There's a combined cable protector and 
paper shield to prevent paper becoming 
entangled with your mains and computer

Two colours better? 


TO IGNORE THE £50 CITIZEN TWO-COLOUR 


| COMMODORE MICRO OWNERS CAN'T AFFORD 
| PRINTER, SAYS CHRIS JENKINS 
| 





he sheer bulk of most dot-matrix 
printers, along with the not 
inconsiderable cost, is enough to dissuade 
many potential purchasers from making the 
investment. If your home set-up is limited 
to a small area, the problems of fitting in а 
printer, with all its attendant wiring and 
paper stacks, can be just 100 much hassle. 

Commodore computer owners now have 
the perfect solution, in the form of the 
excellent Citizen 2-Colour Commodore 
Printer. 

Priced at an incredibly low £49.95, the. 
Citizen is deceptively small and unobtrusive. 
At first sight, the natural assumption would 
be that it was some form of plotter, similar 
to the Commodore 1520, or maybe a 
thermal paper printer. But nothing could be 
further from the truth; it's a full function 
dot-matrix device, which, although it can 
only print on 23” “till-roll” paper, is 
incredibly efficient and useful, 











Serial 
Measuring only 240 x 176 x 81 mm, and 
weighing in at 2Kg, the Citizen is so small 
that it will fit on the most cluttered desk 
(and I should know!). It's mains powered — 
| none of the worries over power failure 
associated with battery devices — and comes 
| with a built-in Commodore serial interface 
for complete compatibility with the Vic 20, 
CBM 64, SX-64, C128, Plus/4 and C16. 
Controls are kept to a minimum. On the 
back are the ON/OFF switch and the serial 
port (just the one). On the front, three 
LED's; red for ALARM, in case of paper 
jamming or data error, and green for ON 
LINE/OFF LINE and POWER; and three

buttons, LINI ELECT (online) and 
bi СТ (offline). That's all there is to it. 
The paper “till roll" mounts on two arms. 
which clip to the back of the printer, and 
feeds through under the cover and across. 
the print head. There's a tensioning arm to 








clear, although obviously limited to 40. 
column width. This can be an advantage if 
you are printing out program listings, since 
the printout appears in exactly the same 
format as the listing on the screen. 

With a print speed of 65 characters per 
second (48 lines per minute in 40-column 
mode), the citizen is by no means slow. 














keep the paper taut 


Addresses 

In operation, the Citizen is like most 
other Commodore-compatible printers, 
except for the two-colour capability. The 
manual, which is surprisingly full and clear 
considering the low-end market at which 
this device is presumably aimed, explains all 
the business of device numbers, addresses, 
secondary addresses and control codes 
needed to operate any Commodore printer. 

Several useful extras can be accessed by 
using simple CHR$ messages. The line 
spacing, normally set to 55 mm, can be 
altered using a secondary address of 6, and 
you can select either the upper/lower case 
or upper case/graphics mode using SA 7. 
Most usefully, the width of the characters 
printer can be doubled using CHRS(1), 
changing the matrix size used from the 
normal 7 x 6 to 7 x 12. There's also an 
INVERSE printing function. 

Printing in red is achieved using 
CHRS(20). You can't mix red and black on 
one line. The red/black ribbon used is a 
standard size which shouldn't be difficult to 
obtain when you need a replacement. 

Bit image programming allows you to 
define your own graphics characters using 
simple Basic commands, and there are also 
commands for paging, carriage return and 
line feed. The print produced is remarkably 


















lack the refinements 
of some printers ~ multiple serial ports, 
fancy paper feeds, compatibility with a wide 
rage of non-Commodore machines, and the 
like — the Citizen is absolutely ideal for 
producing listings, programming notes, 
financial figures, and so on. It wouldn't do 
for word processing because of the paper 
size; but just for the hell of it, I tried it with 
Paperclip software and got faultless results. 

At this price, any Commodore micro 
owner without a printer could hardly afford 
to ignore the Citizen. In fact, even if you 
already own a printer, wouldn't you like to 
go one better than the Joneses and own 
two? The Citizen Two-Colour Printer makes 
it a distinctly interesting proposition, 4

Logical and systematical 


Ken Garroch takes a look at the learning possibilities of Logo 


Papert and his colleagues at the 

Massachusetts Institute of Technol- 
оду, as а computer language aimed main- 
ly at school children to help them to learn 
to think logically and systematically. 

Its main feature is Turtle Graphics, used 
ав the graphic output, The turtle is usually 
a small triangle which is moved around the 
screen, although most Logos also have 
facilities to use a real "ме" turtle on a 
piece of paper on the classroom floor. The 
commands available, to start with, are 
very simple and fairly few. For example, to 
move the turtle in a square, the following 
sequence would be executed: 

FD 10 
RT90 
FD 10 
RT 90 
FD 10 
RT90 
FD 10 
RT90 
FD 10 
RT90 
(FD = ForwarD RT = Right Turn) 

This may seem a little tedious. Fortu- 
nately, there is structure built into the 
language in the forms of TO and REPEAT. 
So, a shorter version of square would be: 
TO square 
REPEAT 4[FD 10 RT 90] 

END 

The 7Ostructure is used to define words 
in a verb type manner. Once defined, 
square can simply by typed in to make the 
ше draw а square. REPEAT is pretty 
obvious; it says repeat the next sequence 
а specified number of times. To give 
square different sizes, a variable could be 
introduced 
MAKE "side 10 
TO square 
REPEAT 4 [FD side RT 90] 

END 

The language of turtle graphics general- 
ly follows this simple style, allowing words 
to be made up of other words, ед 
TOpatt 
REPEAT 6ü[square RT 6] 

END 

which will produce a pretty pattern, The 
idea is to enable children to develop some 
idea of geometry by experimentation. For 
instance, once a square has been defined, 
a hexagon is simple, just change the angle 
from 90 to 60 degrees and up the number 
of repetitions to six. From here, а circle is 
but one step, along with the ideas of 
infinity and approximations 

All of this may sound easy, or complicat- 
ed, depending on your point of view. 
However, the main idea is to use the 
language and develop at your own speed. 
Once the ideas of structure have been 
taken in, Logo allows the manipulation of 


| OGO was designed by Seymore 


words, numbers, and symbols as in most 
other languages but, in a different way 

In the early days of artificial intelligence. 
one language that came to the fore was 
Lisp (Literally thousands of parentheses). 
This allowed the manipulation of informa- 
tion as a series of lists. 
(ABCD) 
is a list of letters with A at the head, and 
BCD as the tail. In turn, A may have a list 
attached to it known as a property list. 


Logo and Lisp 


Seymore Papert was working at MIT in the 
artificial intelligence laboratory, where 
Lisp has its roots, and so it is not surpris- 
ing that Logo and Lisp have quite a few 
similarities. In fact, early versions of Logo 
were written in Lisp and apart from the 
turtle graphics, Logo is very similar in 
style and structure. 

All information is treated as a list wheth- 
er it be numbers or words, so: 

[This is a list) 

is a list of words апа 

[1232 46] 

is а list of numbers. To extract items from a 
list, the commands /TEM, and FIRST can 
be used, so 

FIRST [This is a list] 

returns This. 

ITEM 3 [This is a list] 

returns а 

The actual commands vary from version 
to version. In the main, those used here 
are general and may need alteration to 
work with one of the common versions 
such as Dr Logo from Digital Research (as 
bundled with some of the Amstrad 
machines). 

Being able to manipulate data in list 
format brings us back to the main idea of 
Logo, which is to teach structure. Every- 
thing in the world can be defined as 
belonging to a set or list. Many things 

















Simple Turtle Graphics 


come in pairs (shoes, arms legs, elc), 
Others such as apples, pears can be 
grouped in different ways. A pound ol 
apples may contain four, but apples can 
also be said to be part of the set of fruit 

In Logo, these concepts can easily be 
represented as the lists. 


MAKE "apples [apple! apple2 apples 
apple4] 
MAKE “Huit [apples oranges pears 
grapes] 


MAKE "diet [fruit water veg] 

The structure of the diet can hence be 
broken down. 

Logo has data structuring implicitly built 
in, unlike most olher computer languages. 
where allowing one object to relate to 
another is a matter of defining special 
structures to hold the information. In Ba- 
sic, it is almost impossible to do this in a 
way that is easy to understand. In every- 
day objects, however, laying everything 
out in sets with their relations implied in 
their titles is as natural as breathing. The 
other main feature of Logo is how pro- 
grams are written. 


Minor parts 


Taking the idea of lists, and expanding the 
idea of defining words to do things as well 
as mean them (Verbs and Nouns), pro- 














‘24/POPULAR COMPUTING WEEKLY 


19-25 JUNE 1986 

















grams are written as a collection of small 
Sections that perform minor parts of the 
whole. This idea of splitting up a program 
into smaller, more manageable parts is 
applicable to all programming and all 
problems and, perhaps, a desirable way of 
thinking 

All these technicalities may lead you to 
think that as a teaching language (or 
environment), nothing definite 15 learned 
when using Logo. For instance, there is no 
learning by rote, no geography, history, 
elc. All of which is true except when you 
take into account the circumstances under 
which Logo can be taught. Logo programs 
need some information to work with and, 
after all, most subjects are mainly about 
details and procedures, all of which can be 
included in Logo programs. 


Concept learning 





Now that the Amstrad 664 and 6128 have 
become widely available, more people will 
be coming into contact with Logo. It has 
been available on machines like the Apple 
|, BBC, and RML, for quite a while, but 
unfortunately, it has not caught on. This 
may be due to the misunderstanding that 
computers are really only suitable for 
children (and adults) over the age of 12. 
Logo is not a computer language ог the 
training of future programmers (although it 
gives a better grounding than most other 
languages), it is a world waiting to be

explored like an adventure game. It has all 
the primitive words and commands avail- 
able. all that has to be done is work them 
into something, learning the concepts of 
structure and geometry as you go. It is 
ideally suited to younger children who are 
just beginning to learn the basics of read- 
ing and writing 

As has been said, the are number а 
versions available, there most common 
being Dr Logo. This will run on most CP/M 
systems that provide graphics output. Un- 
fortunately, it is very slow, a fault wit 
nearly every implementation I've seen. 
The turtle graphics take a while to gener- 
ate when compared to other computer 
graphics systems such as those provided 
from most Basics. 

There is not very much standardisation 
between the various versions, different 
words are used for different things, lead- 
ing to confusion. However, the basic turtle 
graphics instructions are usually the 
same, it is the extensions that аге non- 
standard. Unlortunately, the same cannot 
be said for the list processing commands. 
and when going from one version to anoth- 
er, a lot of time is spent rooting around in 
the manual to find out exactly the word 
needed to do a particular job. 

Logo is a much misunderstood lan- 
guage, which accounts, perhaps, for its 
lack of popularity. It is not so much a 
programming tool as are other languages,

SCROLLER 


by Chris Gibson 


his short machine code program 
| allows the user to input a message 
(up to 255 characters long) which will 
then be scrolled at the bottom ol a Mode 7 
screen under 6502 interrupts. This means 
that any Basic program can be run at the 
same time without affecting the scrolling 
Thus the program could be used as part of 
a title sheet to а game. 

Just type in the program and type Run, 
The screen will clear and the message will 
begin to scroll. To stop the scrolling type 
Call Disable — typing Call Enable will 
resume the scrolling 

The way the program works is to store 
each individual character in the string M$ 


ina reserved data bank called Bank (Lines 
350 to 390). The computer then sels the 
interval timer to the value held in the 
memory locations called ‘Speed, This 
must be a negative number as the timer 
increments it by one every hundredth of a 
second. 

When the timer becomes zero an inter- 
rupt occurs and the computer jumps to the 
routine (labelled Hout). The status of the 
computer is stored on to the stack (Line 
110) and the scroll is carried out (Lines 110 
to 130). The timer is reset (Lines 160 to 200) 
and the computer status is restored (Line 
150). The computer is then allowed to carry 
on with its normal functions,

Programming: Amstrad 

















his week sees the second and final 

| helping of listing for the Sound Ое- 

signer program we started last 

week. As explained before, the utility is 
fully icon driven and very easy to use. 

Files are loaded into the sound designer 

by selecting the Load option. Any enve- 








lope not included in the file being loaded 
will not be affected — therefore files can be 
merged into the designer from various 
difterent files if required. 

Selecting the Disc icon (which will only 
operate if you have a disc drive connect- 
ed), will produce the same menu as for 





SOUND 


by Brian Cadge 


tape, allowing loading and saving of files 
to disc. An additional option is Directory, 
which will display the filenames of all Env 
files on the disc. 

The penultimate icon shows a fat cross 
X' – selecting this allows you to clear the 
entire current envelope settings. Select 





26/POPULAR COMPUTING WEEKLY 





19-25 JUNE 1986 





Programming: Amstrad 





"Wes! to go ahead, or ‘No’ to cancel the 
command, Clearing the envelope wipes 
‘out the volume graph and resets the vibra- 
to settings. Only the current envelope is 
cleared, all others remain unaffected 

The final icon shows a left pointing 
arrow, this is used for deleting the last 
section of the current volume envelope 
entered on to the graph. И no sections 
have been entered then the command is 
ignored. 

‘Attempting to add more than five sec- 
tions on to the volume graph will produce. 
an error message and will be ignored, as 
will attempting to add a section that goes 
"backwards! in time. 

A little experimentation with this pro- 
gram can create some quite impressive 
results which, when combined into your 
‘own programs, could have your Amstrad 


sounding like a small orchestra (maybe) 

For those interested in the workings of 
the program, the various subroutines and 
key sections of code have been fully com- 
mented. The small section of machine 
code at the start of the program is used to 
produce the small arrow which moves in 
response to your joystick: you will find it 
produces a smooth and flicker free point- 
er. The routine exits to Basic when the 
joystick fire button is pressed. 

Owners of an AMX Mouse for their 
Amstrad may like to know that the program 
will work equally well with this, rather than 
а joystick, without modification — you do 
not need to load any other software first. 

Whenever а new volume envelope sec- 
tion is added, the program automatically 
works out the “рез fit’ line which will 
produce the correct volume change over 





the required time. It is only limited by the 
Amstrad's sound hardware. 

The usual technique is used for check- 
ing for the presence of a disc system. This 
involves setting an On Error trap and 
calling the | Disc command. И this com- 
mand exists then no error will occur and a 
disc system is present. If it does not exist 
then an "Unknown command’ error will be 
caught and the program will note that no 
disc system is present and default to tape. 

All sound designer files are simple Ascii 
files which contain Basic compatible Env 
and Entcommands on separate lines start- 
ing at Line 500 in steps ol ten. The program 
checks for syntax errors when loading in а 
Ше and will abandon the load if any are 
noted- this will only occur if you attempt to 
load in files which have not been produced 
by the Sound Designer,

Programming: QL 











inclair SuperBasic is a powertul and 

flexible programming language, but 

it lacks some facilities, including a 
mechanism to 'trap' unexpected errors. In 
this article we provide a new command to 
banish errors associated with file and 
device handling, and reveal a simple pro- 
gramming trick that makes the error in 
expression message a thing of the past. 

Other Basic interpreters allow an On 
Error Goto statement, or something simi- 
lar, which diverts the computer to a certain 
line when an error occurs. Late versions of 
the QL recognise a When Error command 
which resembles On Error Goto, but this 
has а number of snags. 

When Error only works on versions of 
the QL from JS onwards. This means that 
you can't use it in programs which аге 
intended to run on any QL — most British 
machines belong to versions АН or ЈМ, 
which do not allow the new commands. 
Secondly, When Error is an undocumented 
feature of the QL. Sinclair didn't explain 
the command in the QL's documentation, 
во you have to use it by trial and error. 
Finally, the implementation of When Error 
‘on the JS and MG OLs is far from bug-free 
This combination of factors makes it little 
more than a curiosity. 

In this article we present an alternative 
мау of checking for errors, in the form of a 
new SuperBasic function, Status%, which 
will work on all versions of QL. The func- 
tion lets you check the validity of file and 
advice names from within a program, 
avoiding errors such as in use, not found, 
already exists and bad name. 


Status report 
Status% is a function which expects a 
single string parameter. The string should 
be the name of a QL device, followed by 
parameters (if any) or a file name. 

The function analyses the string to find 





QL TRAP 


by Simon Goodwin 


ош whether or not it starts with the name of 
а device on the current QL. Any parame- 
ters of the name are then checked (tile 
names, or extra information, as in 
serTEHC). Finally the function attempts to 
open a channel to communicate with the 
device specified. If successful, the channel 
is closed and any file which has been 
generated en route is deleted. 

Status% returns an integer (whole num- 
ber) which indicates the degree of success 
it had in performing these operations. The 
possible values are shown in the table 

The function can cope with any device 
linked into the QL's QDOS operating-sys- 
tem - including add-ons — so you can use it 
оп а basic QL, secure in the knowledge 
that it will also work with floppy discs. 
modems, parallel printers and so on. 

The following command indicates that 
the file ‘Supercharge’ exists on floppy disc 
number 1 
Print Status*s("flp1. supercharge") 

-8 


The program 

The code for Status% occupies only 112 
bytes. It links itself into SuperBasic, so you 
can use the function in any Basic program 
once it has been loaded — you can treat it 
just like one of the built-in functions. 

The listing consists of a simple Basic 
loader which reserves space lor the com- 
mand and Pokes it into memory. Type it in 
then Run. The Са! command in Line 210 
links the new code into SuperBasic. Once 
the message Status% Loaded, has been 
printed you can delete the Basic — it is only 
needed to set up the code in reserved 
memory. If you accidentally mis-type some 
of the data the computer will print an 
appropriate message. Correct the error 
and re-run the program. 


Trick arithmetic 

Status% is very useful, but it can only trap 
errors associated with files and devices. 
Programs can often be made to crash И 
text is entered when a number is required, 
and Status% cannot help with this prob- 
lem. Luckily а simple programming trick 
can be used to get around this. If your 
program contains the command /nput X, 
the QL will read any sequence of charac- 
ters from the keyboard until Enler is 
pressed. The computer then tries to evalu- 
ate the characters as И they were a пит- 
ber. И the characters are not numeric the 
program stops with the report error in 
expression. Luckily it is possible to get 
around this problem, in most cases, with a 





single extra statement. The solution is to 
read the characters as a string at first, so 
that they can be checked within your 
program, rather than by the QL system; 
Input Temp$:X= "0" & Тетр$ tor instance. 

We now use the string variable Temp 
as a temporary store for the characters, 
The digit '0' is tacked on to the front of the 
string before it is copied into X, the numer- 
ic variable. If the string was numeric, the 
extra zero at the start will have no effect on 
the value — for example, 125 and 0125 
represent the same value. If the string was 
not numeric, X, takes the value zero, since.

the QL stops evaluating as soon as it finds 
а non-numeric character. In either case 
there is no error, 

This is @ uselul trick, but it does not 
allow you to distinguish between a ‘real’ 
value zero and one that indicates an error. 
In most cases this won't matter, but if need 
be, you can filter out real zero values by 
comparing Temp$ with "0", immediately 
after the Input. If the strings match you can 
set X to zero immediately, and jump past 
any code that might otherwise reject it 

There are a few other special cases to 
be checked for. If the user types a capital 
or small letter "Е" you'll stili get an error, 
because the QL expects an ‘exponent’ 
after and ‘Е’; in a number: ‘OE! is illegal 
where '1E6' is fine. Very big numbers — 
such as 1£700 - also cause problems. 

Finally, the QL only allows a digit, or 
nothing, after a decimal point, so you can 
fool it by typing in two full stops. In practice 
itis ready to check for these cases and you 
can often get by without bothering about 
them, and still have your programs fairly 
well error trapped.

raphics is a machine code routine 

which allows access to high resolu- 

tion graphics from Basic. Nine new 
commands are added to plot points, draw 
lines, change colours etc. 

The program consists of 1140 bytes of 
machine code, residing at $000 (49152) 
which means it is untouchable by Basic or 
the Operating System. The high resolution 
screen sits al $2000 (8192), mainly due to 
inadequacies of the VIC chip. Consequent- 
ly, for programs larger than 6K ($0800 — 
$2000). Basic has to be moved to $4000 
above the screen. Even so, this still allows

To use Graphics, type in Program One. 
exactly as it is printed and save И. Once 
salely on disk or tape, type Run. If there 
are any errors in the Data, the program 
should point them out to you. Once it 
reaches the end (when it prints "OK") 
save it again. this one being the final copy. 
Any previous copies can be deleted. 

Now type New which will remove the 
Basic loader program but leave the ma- 
chine code intact. The new commands are 
now active. 

The screen is divided into 320 columns 
by 200 rows (64,000 pixels) each of which 
can be defined as a backround or fore- 
ground colour. Each pixel is relerenced by 
an x (0-319) and y (0-199) coordinate. 

The colours are now defined in blocks of 
8x8 pixels, each block having а 
backround and foreground colour. These 
blocks from now on will be referred to as 
attributes and are specified by x (0-39), 
and y (0-24) coordinates. 

The commands are all prefixed by Sys 
49152. eg- Sys 49152,Р.10050 plots a 
point at 100,50. The nine commands are as 
follows:— 

G-Enter Graphics mode. 

T-Return to Text mode. 

C, b, {Clear the graphics screen to either 
foreground or backround (as зе! by 
the last D command) and set the 





backround to colour B and the fore- 
ground to colour F. 

Paxy-Draw a line from the coordinates 
(ку), of length 1 and in a direction 
indicated Бу d. d = direction, 0 Up, 
1= Right, 2= Down, 3= Left 

D, cfc is 1 then P, plots a point in the 
foreground colour and C clears the 
Screen to the backround colour. If c is. 
0 then these are the opposite way 
around. 

А, x, y, b, f-Set the Attribute at coordinates 
x, у to the background and 
foreground colours b and f re- 
spectively. The x and y coordi- 
nates are in the range 0-39 and 
0-24 respectively, unlike the 
other commands. 

M-Move Basic to $4000 
(16384). This command fol- 
lowed by New will move 
Basic above the Hires 
screen. This should be 
typed in before using pro- 
grams greater than 6K (in- 
cluding variables). | would 
suggest that i is always 
used at the start of a 
session. 

V-Dump all the simple variables (ie, not 

arrays) to the text screen.

referred to earlier have the following

you may cry, but the difference is, 
that this one is written in compact machine

the original version on the Horizons tape! 


Type in and run the loader program, 
entering the start address as 29997. Now 
enter the data in listing two from leftto right, 
with the checksumatthe end. All being well 
you should be able to enter the next line.

Menu Writer 


on Spectrum 
by BE Ashley 


This is a routine for Spectrum utility writ- 
ers that find Menus a tedium, in that it 
centralises the vertical text, highlights the 
title and checks the input. 


Line 1120 restores Data line using variable 
Data 

Lines 1130 - 1140 Print Menu heading in 
Bright, 

Lines 1180 — 1170 insert blank lines for 
vertical lab. 

Lines 1180 - 1210 print Menu options & 
selection number 

Line 1220 prints selection request again in 
Bright 

Line 1240 checks for valid selection 


List 2 is for reference. Load it to print a 
sample menu. Any further menus simply 
require three lines similar to List 2 

The program as written will evenly space 
out eight selections clearly: add further 
Menus to increase,

Hi-res Print 


on CBM 128 
by Stephen Hardcastle 


Here's a short subroutine which enables 
you to print a standard bit-map graphics 
screen (Graphic Mode 1) onto a CBM 1526 
printer. The subroutine may be included in 
any program provided the names о! vari- 
ables used in the main program don't 
clash. 

To test that you have typed the subrou- 
tine in correctly, you could enter one of the 
‘graphics programs from the system guide 
(page 8-13 is the best in my manual). Type 
in the subroutine and save it, then enter 
and run a graphics program. The hires 
graphics screen will remain intact provid: 
ing you don't use a Graphic Cir command 

Next just load and then run the subrou 
tine with Gosub 2000; № all is well then the 
screen will go blank and the printer come 
to life. The printing takes а long time but 
lhe result with a good ribbon is worth 
waiting (ог 

For any one with a CBM MPS 802 printer 
here's а good chance this program will 
work as И stands.

on Amstrad 
by Martin Thomas 


Here is a short program for the Amstrad 
machines. When run it produces a stepped 
landscape that looks quite interesting. 

To be more technical, it produces а 
three dimentional graph of a log function If 
the expression /nt(2"Log(x-- y) in Line 40 is 
replaced, another view is obtained. 
Examples include: 
Int(2"Tan(x"y!1100)) or 
1100).

guitar tutor packages, omitting only 

to mention what machine they ran on 
— the C64, as it happens. This week anoth- 
er guitar tutor program for the same ma- 
chine has turned up as part of a much 
more complex system marketed by Col- 
leen under the name Music Compendium. 

The Compendium has several sections 
including a Music Theory Tutor, Guitar 
Tutor, DID (sound) Chip Tutor, Playalong 
section, Drum Machine and Sound Cre- 
ator. Good value for money for the price of 
опе tape or disc, you may think 

The Music Theory section is in two parts, 
covering first the stave, treble and bass 
clets, notes on the stave, ledger lines, bar 
lines and repeats, and then note values, 
rest values, time signatures, ties, pickup 
notes and accidentals. If you have to learn 
music theory there are worse ways, and 
the Colleen package persuades the C64 to 
give you musical examples as you go 
along, It's hardly the same as having an 
‘open book in front of you though, let alone 
a human teacher. 

Still, it should be possible to pickup 
some basic terminology to enable you to 
go in to the Guitar Tutor. This simply 
allows you to punch in any major, minor, 
seventh or minor seventh chord on a grid, 
and shows you what fingers to use and 
where to play the chord on a guitar finger- 
board. The computer sounds the chord in а 
plunky sort of voice simultaneously, and 
you can tune up each string of your guitar 
to the computer before starting. 

The SID chip tutor is a little odd, cover- 
ing most of the Pokes necessary to 
squeeze sounds from the C64 chip, but 
‘omitting the random and envelope settings 
and referring only to the user's manual for 
any hint as to how to produce musical 
tuning. When there's a fab book around 
like Electronic Music on the Commodore 
64 (author Mark Jenkins, published by 
Sunshine Publications, and where's this 
month's royalty statement?) it seems more 
fun to work through the SID chip more 
comprehensively yourself, 

The playalong section is good fun 
though —it produces boogie, country, disco 
ог waltz backings in any key, controllable 
from a Music Maker keyboard if you have 


l ast week we looked at a couple of 


A musical education 


Mark Jenkins looks at some new music packages for 


the C643 and Atari 520 


one, at a choice of three tempos. 

The drum machine is similarly good fun, 
allowing you to enter 2- to 10-beat patterns 
of up to three voices and chain them into 
songs. Forty bars can be created and 
edited and there's a good selection ol 
swishy percussion noises. 

Bars and patterns can be loaded from 
and saved to disc and any bar may be used 
as many times as you like in a pattern, and 
can be copied or moved within the pattern. 

The last part of the Compendium, the 
sound creator, has three distinct sections, 
the creator, combiner and effects master. 
As these are a little complex (with the 
ability to create music and sound effects 
for your own programs) we'll take a look at 
them next time, pausing only to remark 
that the Colleen package seems a good 
buy for those wanting a little musical 
‘education, tor those who think they may be 
interested in music but aren't sure (re- 
member it's not just about dots on a piece 
of page) or for those who want to use their 
64 as a basic accompaniment machine for 
other instruments. The whole compendi- 
um is available on a double-sided disc at a 
reasonable £29.95, and sections are also 
available individually.

A little more upmarket now with the 
latest MIDI packages from Steinberg, 
which is launching а whole new range at 
the British Music Fair at Olympia from 1st- 
3rd August. 

Pro 24 is a 24-track MIDI sequencer for 
the Atari 520ST and 1040ST with 5,000 
patterns, 200,000 events, up to 64th note 
quantise or real-time recording, individual 


STYLE SELECT 
















not and MIDI event editing, single step 
recording, insert, delete, cut append, re- 
peat, punch in and out and much more. For 
£165 it seems set to become the industry 
standard MIDI composer package. 
Pro-Crealor is an editor for the Yamaha 
FM synths which also has the capability ог 
creating sounds randomly down to the 
name displayed on the synth's LCD. Cost 


is £120 for the Atari version. 

Track Star is an eight-track MIDI se- 
quencer for beginners on the Commodore 
64/128 which includes four sampled drum 
sounds of bass, snare, hi-hat and percus- 
sion. It has four demo songs and six demo 
rhythms, punch in and out, fast forward 
and rewind and many other facilities, and 
is £70 including a MIDI interface. 

The Edit Kitfor Pro 16 composer files оп 
the C64/128 has ten octave range and 
complete editing facilities down to the last 
note and MIDI or drum event. Cost is £30. 

Из now possible to buy Pro 16 for the 
C64/128 on an Eprom with built-in interface 
for £177.50, and Steinberg also markets 
editor packages for synths from the 
Ensoniq Mirage Sampler to the Korg DW- 
6000, Contact OSC at 68 Wilsdon Way, 
Lyne Paddock, Kidlington, Oxford, 0865 
67056. 

We'll be looking at some of these prod- 
ucts in more detail in the near future

Keyboard query 





Mark Griffith, of Cambridge, 
writes: 


am thinking of buying a 

microcomputer. Is there a 
keyboard with the Dvorak lay- 
ош that | can buy to go with а 
РС? 


А The Dvrorak keyboard lay- 
out is used to enable touch 
typists to go faster, it has the 
same number of keys as a 
normal keyboard but with a 
different layout. The idea is to 
put the more commonly used 
keys in more convenient posi- 
tions. In fact, the Dvorak key- 
board is so similar to the nor- 
mal keyboard that it may be 
just as easy to redefine the 
keys rather than invest in a 
new keyboard 

Superkey, from Borland (Al- 
tar Computers 041-228 4211 
price £69.95) is a piece of soft- 
ware that will do this for you, it 
comes with the Dvorak layout 
as standard, 

There are two other types of 
‘go faster’ keyboards that you 
might like to consider, the 
Maltron, and the Velotype 
Both use completely different 
keyboard styles trom the norm, 
Velotype allows a number of 
keys to be pressed at once and 
in contoured to fit the hands, 
the Maltron is contoured, and 
has a special layout allowing 
the hands to be as still as 
possible. 





Amstrad INK 


P Grey of Wirral Merseyside 
writes. 





1 recently purchased an 

Amstrad CPC 6128 micro 
computer and have been trying 
fo come to terms with its Basic 
programming language. One 
thing that | am having a little 
trouble with is how the colours 














are placed on Юю the screen, in 
particular, what INK, PEN, and 
PAPER do. Could you make it a 
little clearer? 


To be honest, | also had a 

little trouble with these 
commands since they are not 
explained very clearly in the 
manual 

After a lot of playing 
around,here is my understand- 
Ing of how it works. 

The Amstrad has 27 colours 
available of which a selection 
can be placed on the screen at 
any one time, depending on the 
screen mode. In mode 0 there 
can be 16, mode 1 has four, and 








up. it can be used on the 
screen, either by PAPER, PEN, 
ог graphic commands. So if ink 
1 is set to blue, the command 
PEN 1 will cause anything writ- 
ten to the screen to appear 
there in blue. Paper works in 
the same way with the only 
oddity that the paper is defined 
as the cell within which the 
character appears. 

И you want to change the 
colour of the screen, find out 
which ink is currently assigned 
to paper and alter the colour 
assigned to the ink. 

To sum up, the computer has 
а pallette of 27 colours, 15 of 
which can be assigned to inks,

mode has two. The colours that 
appear on the screen can be 
any from the 27 and are select- 
ed using the INK command. 
The INK command can have 
up to three arguments INK 


N,C1,C2). the first of which 
specifies which of the 16 inks is. 
to be assigned a colour. so the 
command INK 2,3 assigns red 
(colour) to ink number 2, INK. 
2,3,1 assigns two colours (red 
and blue) to ink 2 as flashing 
colours (alternating between 
red and blue). 

Once the ink has been set 


TES

these inks are then used by the 
PEN, PAPER and graphic 
commands. 

The program below demon- 
strates how graphics can use 
colours and switching of col- 
ours, at the ink stage, to create 








simple animation. 

Logo lists 
Graeme Watkinson of 
Burntwood in Staffordshire, 


writes: 


! own an Amsirad PCW 

8256 and have been trying 
to use the DR Logo program 
supplied. | have managed all 
right except that І cannot get 
the Dot command to function 
using any of the variables in 
the program below: 


to CURVE 
make “x0 

repeat 260 [make “a 80°sin: < docu] 
така ^x] 

end 







The program, which is de- 
signed to draw a simple sine 
curve, stops with the following 
error messag 





dot does not ike [a] ва input in 


Could you please explain this 
error and how this command 
should be used? 

! would be gratetul if you 
could also recommend the ti- 
tles of опе or two books which 
‘explain the language in detail. 


Your problem is one of 

levels, The dot command 
needs a list of two numbers as 
its input, ie, dot [10 20], is OK. 
However, unlike сотриег lan- 
‘guages such as Basic, the con- 
cept of variables is slightly dif- 
ferent, What you are actually 
giving dot is the list [xa]. 
Logo does not immediately 
presume that you mean the 
values contained in :x and за, it 
needs to go to the next level 
down so you have to tell It to 
evaluate the list [са] into num- 
bers. The command for this is 
list. Try the following: 





This has the effect of taking x 
and га and forming the list [10 
20] which is what dot needs to 
work correctly, The working 
version of ‘curve’ is 


o curve. 
make ^x 0 
repeat 380 [mak 
"xx +1 dot liat 
end 


а 0 * ain х mako 








There is another example in 
the Amstrad manual using 
'secursor Logo is based of 
the artificial intelligence lan- 
guage Lisp and most of the list 
processing ideas (converting 
їх га to [10 20] is a list process) 
are the same. 

И may be an idea to have а 
look in your local bookshop/ 
library for books about Logo 
that that suit you but some 
titles that may be of use are: 
Seymore Papert, Children 
Computers and Power Ideas 
(Harvester Press, 16 Ship 
Street, Brighton, Sussex. ISBN 
0-71080-472-5); Tony Hasemer, 
A Beginners Guide To Lisp 
(Addison Wesley Publishing. 
ISBN 0-2021-14634-7), which 
gives all the basics behind list 
processing, relevant to ad- 
vanced Logos; Harold Abelson, 
Logo for the Apple И (Byte! 
McGraw-Hill), one of the stan- 
dard works on Logo for micros.

's a pity this pre-production 
version wasn't here a cou- 
ple of weeks ago; everyone 
seemed to be down with the 
lurgi. If only we'd had Contami- 
nation then. 

You've seen flight simula- 
lions, you've seen business 
simulations — but an epidemic 
simulation — that's a new 
one from the Ere 
Infomatique incidentally, who 
are releasing their excellent 
games via PSS in this country. 

In an Andromeda Strain type 
scenario, a constantly mutating 
virus has been brought to Earth 
Ма a space shot, and you are in 
control of a team of scientists 
trying to contain/eliminate the 
virus and its virulent offspring. 
It may sound a bit dodgy, but | 
found the game fascinating. 

Admittedly, at present the 
game stretches my French to 
its equally dodgy limits, but it 
goes something like this. 

You are head of the World 
Health Organisation who are 
charged with attempting to 
stop the virus from killing ev- 
eryone. You do this by devel- 
oping anti-virus preparations 
in your computer controlled 
lab, then testing the potion for 
things like side effects — alter- 
natively you can try them out 
on the population; И you feel 
lucky. 

The other side of the opera- 
tion is carried out on a world 
map, where you receive infor- 
mation about the virus's 
progress, etc. You can place 
restrictions on infected area, 
even nuke them if things get 
ош of control, but the lafter 
doesn't make you flavour of the 
month with the locals. 

Naturally there's a lot more 
to it than that, but | think it's. 
likely that this intriguing mix of 
puzzle and strategy is going to 
appeal to more than Amstrad 
‘owning Biochemists. The En- 
glish version should be ready 
by late July.

о. it's not a misprint 

Batman, the tabby, 

highly acclaimed, etc, 
arcade adventure is now to 
be found running on the bor- 
ing old Amstrad Personal 
Computer Word Processor - 
but why did it have to happen 
this week? 

As the mighty Joe Sun- 
shine handed me my 8512 
{complete with timelocked 
ball and chain) | couldn't 
help but notice his particu- 
larly wide serene smile -the 
‘one normally seen on the 
face of Christian Scientists, 
or aged Aunts half way 
through their third gin & 
orange. 

Personal ^ productivity. 
This was no computer to play 
games with. This machine 
was going to make me а 
better person; a more pro- 
ductive person. This piece of 
hardware was going to 
change my life. 

| accepted the gift with а 
tug of the forelock and а 
weak grin, resigning myself 
to a future of gloom, only to 
be interrupted by the odd 
game of computer chess. 
And then came Batman. | 











can assure you, never has 
the arrival of a Super-hero 
been greeted wilh such 
‘whoops of joy 

1 remembered the game 
as a great little Knight Lore 
derivative on the original 
machines and wondered cu- 
riously how it would convert 
to а text-only format. It was 
then that various jaws hit the 
floor. There it was. Detailed 
3-D graphics. Wonderlully 
animated figures. Fiendishly 
difficult puzzles. 

Whoever said it would 
never run games wasn't 
reckoning on Jon Ritman 
and Bernie Drummond. This 
is just like the original (albeit 
extremely green) and all the 
more enjoyable for turning 
up somewhere unexpected. 
And of course, if they can do 
it- so can many others. 








and zapping - with your venom 
being directed at cybermen 
types and flying saucers that 
seem to have taken over the 
complex 

With a reputed 180K worth of 








code on the disc, merely on a 
bytes per pound spent this 
would be good value, Com- 
bined with the fact you've got a 
highly entertaining and origi- 
nal arcade adventure to boot, it 
looks like a winner. 

A cut down version (two lev- 
els) is available on tape for 
464/664 owners, but | expect 
6128 owners to go for this in а 
big way.

ваш OVER MOSCOW 


here's no doubt that this 

| particular computer 

game can certainly be 

said to have made its mark оп 

the world. In fact, | can't think of 

any other game that has raised 

the blood pressure of people 
playing. 

The storm at launch was so 

great, that US Gold even 











changed the name to Raid. 
Well, it's now been 'born again" 
under the old title on the BBC. 

The war against the Red Per- 
il gets off to a poor start with 
two errors in the first two pages 
of instructions. After hall an 
hour or so, the controls were 
sorted out and the thing 
showed itself to be a fair con- 
version of the best selling 
multi-screen zapper. 

Re any controversy this 
launch may re-start (| don't 
expect ILEA would like this run 
on its considerable number of 
BBC's, for example) И you 
don't like the politics, don't buy 
it (the ultimate capitalist 
nction). 

In any case, play it with your 
brain in neutral

few months, Quicksilva pro-

was, ‘great graphics, shame 
about the gameplay. Now Paul

er visual opus, Tantalus, and 
once again It's a case of don- 
ning the Foster Grants before

There's no doubt about it, ће 
graphics, one way or another 
are... well... stunning; al- 
though ! wouldn't recommend 
viewing alter a hearty meal 
Evidently Paul is not a Habitat 
fan — still, what about the 
game? 

Lots of very small print on 
the cassette inlay about inter- 
stellar wars and mutants in the 
year 3027, but closer inspec- 
tion reveals it to be a large 
zapper (1024 screens it says 
here) with some adventure ele- 
ments thrown in. 

А fair amount of play has 
suggested this isn't really my 
cup of tea — the aliens (all 48 
different types, each well de- 
signed) just arent vicious 
enough (as | speak there are 15 
оп screen, 14 not moving, with 
one aimlessly wandering 
around as | shelter in a quiet 
alcove) or perhaps it's because 
Ihave difficulty identifying with 
my on-screen persona - а 
Spike Punkoid. 

But there's no denying that a 
lot of effort has been put into 
the thing — and if you're an 
ardent mapper with a loathing 
of good interior design, there's 
а lot here that might interest 
you.
