YOUR COMPUTED 5EP _ EWSER 1985 11 



PROSECUTING 
SOFTLIFTERS 

Ex-CIIEF SUPERINTENDENT Bob Hay, billed as the 
man who helped crack the Iranian Embassy siege, 
police the Grur.wick dispute and quell Sikh unrest in 
S out hall, now faces his toughest case. Software piracy. 

He 5 s head of the special unit set up by the 
Fede radon Against Software Theft (FAST) to root out 
infringers of program copyright wherever they lurk. 
His weapon is the tough new legislation just enacted 
by Parliament. It wLl leave software thieves open to 
punishment identical to the stiff crackdown that hit 
video pirates a couple of years ago. 

If the Copyright (Computer Software) Amendment 
Act works out as intsndedj program counterfeiters — 
already driven out of the video indusrry — will have 
to go back to selling Mexican-built "C artier" watches. 

Alrhough the biggest deierrcn:s are reserved for the 
commercial forgers — up to two years' inside and 
unlimited fines — anyone selling, exhibiting or even 
possessing illegal copies could be stung for up to 
£li,UUU or locked up for a maximum or two months or 
both. 

Thanks to the new Act and the activities of FAST 
the mood against petty copiers has changed. In last 
year's anti-piracy campaign software supremo Geo!: 
Brown of US Gold said they should be hanged, Ndw 
that the software houses have the power of the Act at 
their disposa. they are aware th£t the criminal remedy 
is not always lIic bes. option. 

People must realise that most copying takes mon;y 
away from the industry — and :hat will lead to a loss 
of software choice and a loss of jobs. In the meantime 
games houses will have io take whatever action they cm 
to make petty copying as difficult as possible — using 
protection devices or hardware soluiions like Mikiu- 
GerVs Mikro-Plus Interlace. 

Bui until computer user* tecome more aware of the 
damage that making and swapping copies does, it will 
continue to be i drain on the. market. As former Chief 
Super fob Hay puts it, the loss of money to producers 
and retailors is the stme whether you shoplift £500 of 
goods or sofllifl £500 of girnes. 

Let's hupe It*: llle sale of all of us who enjoy 

computing that the Act will be as effective as its video 
equivalent. Film companies estimate that video copying 
is down a massive 60 percent on two years ago.

the most potent game of 1984 — 
fOmctwc offets you a 50 at ;ts 
vcqucU Rockford's Rio:. Pretty 
soon you dislodge a boulder, 
iriggertog off an nalaachs, Ii gi«s 
you your first nish and tbe craving 
for more returns. To make matters 
wDiit, Mc!iiol.[h hj- included ,1 
copy of Bculdetdish on :he other 
side of the tape. 

Ebckford's Riot uses 'he same 
ingredient* — biuldcrs, jewes, 
jmocbiSv butterflies, fiKfliis, 

enchanicd walls — but presents a 
brand new set of problems. There 
mi :fi levd&'or esr\« as the cssserte 
inlay calls them. In ejeh cove you 



can scroll sntooihly ovtr an area Bt 
least vis times the s:r«n size, And 

in each yott havi to coKcct * given 

n jmber of jewsls wiihin a imz 
limit. But beyond this common 
Sctor rhtre e enormous vajieiy so 
that each level could almos: be 
described as a jcparate guiw 

Take cave B for example. 
Amoebai are oozing oui from the 
turps of 'hrcc large vats. So you 
trust first shift boulders to seal 
them in 1 .. If y*ou succeed the 
aolocbas turn into jewth. Then 
you nive to dish down to the 
bottom c-f the vats, unptu; them, 
and when the aval a ti.hu of 
IwulLeia It*. nvil1;d, tullevl 75 
jeweh before time runs out. 

Collecling jewels is a problem in 
iuelf Thsy arc invariably 
embedded in a pile af boulderf . As 
1 he game si.nulatei peifettly the 
physi:s of ro:k falls, yoj only hai.'e 
to extract one for the whole lot to 
come tumbling down. When it is 
accompanied — as it is on the

However, as it :urns out. teitherof Ehe^o

Thu Ams km i 464 was launched In June ksi 
year at tbout tie same time as the bug-freer Q1..5 
begin to hit the streets. 1 5 months liter only 
50,000 QLs have been sold wldle ihe Amaind 
has esublshed itself as one of the three best* 
vdlbg Ikjiik coiupuicrs in Britain, How is ii that 
in a year when almost eveiy other micro 
manufacturer folded or flour dercd, Amstrad has 
nourished? 

Undoubtedly one reason is thtt rle 4o4 comes 
With a monitor and built-in casiett: reorder ai 
in unproL'edcntly ow price, But ecually 
important is the fact that, alihough its design is 
not especially Ldvanced, it scores highly in almost 
*very depart men: — graphics, stiund, Basic, 
juthiruciiuit, and I/O connections. 

This computer :S largely free of (he qjirks and 
ombsiens thai flitw mas: other mi:rtv: a tacky 
keyboard on the Spectrum, ant quoted Basic on 
;hc CBM-rVt, hup on :he QL and Oric> the 
memory-stirred BBC, and so on. 

Amstrad followed the 464 with tlii 6f4, which 
has a built-in 3is. List drive in place cf the 
M)etfc ncorler. It has i ftw extra Dafic 
rommands such ts the smpfiics commanc t ill. 
jnd sacrifices 1,280 bytes Ktm to the dt&c 
OperatUg system. Bu- its major difference is the 
ibitty in run CfWl 2,2, which is supplied partly 
in disc and partly on Kocr,, Ihe idea behind 
providing CP/M is to wicc-n the mat hiiiA saipe 
loi dlUitiiiiig Li usi ness u\t:rs.

is aUI sobstre compatibl; vith the earlier

Although the 6128 offers more than the 664 
— which vill be Quietly dropped fron" pr>duc-

down simps e. on the icrcen linking lium with

you adc text to the diagram for labels >t titles. 
Despite being able to place a grid pattern on 
the VDU to h*lp with the al.gnrrietit c-r'variovj

shapes or icons to precisely" where I wuited 
them. _^~~~~ 

I liked the Graphpsd' hardware .or its neat, 
robuM design and the drawing program worked 
-veil, There is a listing of th* draw. rig program 
at the lack of the instruction nimiual and it 
should be easy to extent: or mpdily this w stit

was dit appointing. 

The sefMtivc area cf the, Touchmaster

by its own m«ns plug/transformer and must

and parallel ports are fried to the back of the 

case and there is a socket for 1 foot switch as 

.veil. The short handbook supplied win the pad 

shows how it can be :onnected to popular 

jnachkes such as. the BBC ir.icro, CBM-64, 

Dragon 32/M., Spectrum arid Vk-20.

Tbzts really not very difficult. Accessing the

if you need the whele system to ran faster than 
is possible in Basic. inttrfaeing ibe Tnuch-

may veil avoid clashes wirh other peripherals

GZJ.Q0 worts on different principles 10 the

Buttons on the top housing can be used to 
Select a function from a mam displayed un the 
VDU, 'Tift" trie pen from he pad - elect- 
ronically at [cast — ard return to the Menu. 
The sofhvart tuppfifid Willi the Anirogskeleh 
pad worts well and has a couple fit unique 
features. 

"Undo" will erase tic work yiu hay; done 

since the menu- was last displayed and 

L'^lirtor", "Quad" and "Fib" will split the 

screen and capy what yot. art doing cithtT to 

the other side, into .tic tliue itliei quui lerh. ui 

frcm top to bottom. Thit's a good way to 
achieve symmetrical drawings and the undo 
command is much easier to xne than the erase 
functions in mist of the jrhtr packages. 

1 didn't like the iiic.liiiimm Lj ilitr Anirog 
sketch pad pirticularly after using the Bitmap 
and Ton chma iter graphics pads. I would be 
concerned about wear developing in the Rear 
mechanism that turns the potentiometers ;.nd 
the ttc&ctktCM that you iiiiglu appear w gain

fectly well and the drawing package: is perfectly 
adequate :br designing yiuuici and liniiii; them

photographing the screen is one way ofrepro- 
durring what you have created. 

Well made unit 

A light pea is a device which detects when 
the spot >fligh' or. a Riming visual display 
unil — an ordinary TV at monitor — nas passed 
underneath the sensor. In conjunction with saft- 
wiKeui luidwaie, the CRTC chip in th? BBC 
micro, the position of the lightpen on the screen 
can be detcrnined and the information fed into 
a program running in the compute. 

The R H Lightpen b a well made unit. The 
body of die pen is a slim, comfortable in hi Id, 
cylinder with a ted LED a the bfck of the pen 
— fac.rig t ht us it — aid i tapering noszlt ai 
the front. A fleitible lead :otmects the pen to 
a taetil cued ur.it that connects in turn to the 
analogue port of the BBC microcomputer. 

The software included with th; R H Lifihl- 
pei consists of a number of procedures rh:ir ran 
be incorporated into your o^n programs in

with the lightpen. The drew lag routine works 
in Mode D and is much simpler than the soft- 
ware provided with other products Hnwftwr, 
R H Elec mn ics also produce £ program known 
as Art Master, 

Two versions of the Datapen were sent for 
review. One connects to the A tn D port on the 
BEC mictoccmnuic- and the other is ronnccred 
in i snckei which plugs into the bus on the back 
of the Spectrum. It is not possible to plug

The Plotmate plotier ,s n delight to use. I

two um.tns.ons. Other machines, the Epson 
HI-80 for cximple, move the pen in onediroen

CONCLUSIONS 

I A bt of saftwars has been written for 
onscreen graphics displays on mos' of 
the popular microcomputers. Plotmate 
can use thcae programs directly to 
transfer data from the BBC screen to 
the plotter. 

Graphics tablets or pads nave been 
available for some time r or minicom- 
puters and blSi serious jobs. Lhiil 
recently '.hey came with big, serious 
prices attached to :heTi so t?ie Graph- 
pad, Touchmas:er and B tmaD are all 
good value lor money as peripherals. 
I Leonardo Is the best drawing and 

painting progrsn fcr tr>o Spectrum *nd 

you don't even need a joystick or a 
graphics pad. 

lAxsi Bruck's booK Comput&rAri ana 
Graphics Is tuperb It i tustraies Trajjnl- 
flcantry how a computer can be used 
to draw complex repetiiive patterns 
that appear to have depth and perspec- 
tive. The explanation and programs in 
the book can be adapted to draw and 
plct almost tny shape- But that la done 
by Qnterhg figures tf-at detcrl^o the 
various lines and mo/ements neces- 
sary !o Ct>n£)ru;t Ihe shape. None of 
the soltwenro inc ud«d En this review wilt 
allow you tc draw a diagram in three 
dimensions ?n *he computers screen 
with ether a graphics pad or a ugnt pen 
and tten rotate or scale the figure to 
Suit your ne?ds. 

I The video digitiser could be useful for 
preparing sales literature or catalogues 
where yon want to nnhrrln A picture of 
a piecaoi equipment or a logo Into {he 
middle Of a text. It is certainty great fun 
to slay w fh but romornber you'H n&ed 
a standard srjurrje of video signals, an 
ordinary video camera tot example, to 
tetd tie doilce. 

I Fc my purposes. I would buy an R H 
Electronics llghtpen or the Graphpad or 
Tooctvnaste- graphics pad and couple 
that to the Plotmate, wriling the soft- 
ware lo naripulate the data with the 
help of Axel Bruck's book.

This brings us r.tatly to one of the major new 
develop meats wirhiTi the ethical ionsil field in J 
dseuhere: — the availability of cheap 16-bn 
computers. "l"his combats two of ihi restrictions 
<tf curnnl jelivitis. The fust is that working 
on machines like the RM N:mfcvts jnd Aprittit 
FlE has direct relevance 1o industry wilier; the 
same if lot very similar machines are beau: jsed. 
So when vim loam about word pnveesMt.g or

with the &a.ne software as is in commercial use. 

Also, wriinp dctnl, itHervslirg a:id extensive

uiacJiinc is ustnot up to k. But with wbizz-bang

developers wit. really be able to ge: their teeth 
into applications. 

16-bii computing with its icon technology, 
highspeed graphics, lirgc memory capacit* and 
most Important, ease of use adds up to better 
software, better applications and i better learning 
environment. 

What loot lite being thj iinnl push firm MEP 
— the quango set up in \Q8l to oversee educa- 
tional computing — is in the area of 16-bit 
educational sofiwttc development. Re:en:ly, a

There are many scenarios for the school of the 
liiinrc but oner of the mrat Risible h the 
incr:asLd amount of time pupils will study it

THE LOW COSTCOMPLTERFORHOME AND BUSINESS 



If you knowanythi ng 
about computer* you'll 
know that disc drives are 

Up to fifty times faster 
than cassette when you're 
loading and sav:ng 
programs. In fact, a 
disc drive makes 
computing faster, 
more reliable, more 
efficient and more 
fun Rir up till now the 
only way to gain these 
advantages for a home 
computer was to buy a 
separate disc drive 
attacliment. New Amstrad 
are pleased to announce 
the first complete home 
computer with built-in 
disc drive; The Amstrad 
CPC 564, 

And when you buy a 
CPC 664 you'll find it's not 
just the disc drive that's 
built-in 

You'll get every- 
thing ycu need, including a monitor 
(green screen or M. colour). We'll 
even give you a free CPM and Logo 
diiL, so all you do is plug in and 
you're in business, 

BUSINESS OR 
ple asi mr. 

Although a disc drive 
will make games more fi:n 
taitd there are loads of 
them to choose from) it 
also makes the CPC 664 





famous-name software 
houses. Few will cost 
you more than £49 and 
moht will cost you con- 
siderably less

plete range of 
peripherals avail- 
able to CPC 664 users 
which plug directly into 
the built-in interfaces. 

These include a joy- 
stick, additional disc drive 
(to double your on-line 
storage) and the Amstrad 
DMP-1 dot-matrix printer. 
(There's also a cassette 
interface so that you can 
use CPC 464 programs 
on tape). And there are 
many mare peripherals from 
Amstrad and other manu- 
facturers which can be used 
to enhance the CPC 664. 



HIGH PERFORMANCE 
-•LOW COST 



The one thing you won't need 
a computer to work out is that the 
/•mslrad CPC 664 
represents outstand-

Aiticricin aotbvart out was aot its quality but

The Atari 400/800 which Geoff still believes

Sneak screen shots of the next batch of games 
from Britain's biggest selling software house. If 
it's so simple for U.S. Gold to scoop the best of 
America's games how come no-one else beats^ 
them to it? 




But it was Access thst put U.S. Gold an the

the movement of the rgs- I ended up partly 
pinning an idei I hadsee^i ir. a fiend ol'mine'i 
game "Monsters" which ht: wmit! sumc time 
jju nn the Atom, The basic idea is that the egg 
o' e[gs :heck whether or not >ou arc on the 
Sinn: level as then- — if so they move '.awards 
y<Sa or else lllcy aunt; about randomly unfit 
they find a ladder and therij copending on your 
pssidon, move up or down. Thanks to Ancrcw 
Greene for the idea, 

The next problem was the mnvtmert of trie 
two burger?. 1 solved this by string aside eight 
memory loeations : each contair.lng a number 
yihich corresponds 10 the piece of burger and 
the extent id which if has been waked on 
Thoe memory lot; lions are then moved 
around after the piece of burgtr has stopped 
mm- ;n£, Ycu have an advantage ov*r Freca — 
the ability Id drop one level and leave the egg 
stranded on a platform. However, this 
advantage b slowly taten awi, y from you as you 
ga through the six sheets. Any BBC users who 
wish to play th: gi me will have to increase lb; 
number* held n the X and Y registers in ih>

Each of the foir programs should be lypcd in,

[he pxKtssot is trying to execute una rather thar

results. 

This aieans tht game is played by twe 
players. Each writes t program, of maximum

If yiw try O execute data as an- instruction,

in that core location 2999 "wraps round" and 
is next to location 0. This means that

Cbvkiwly;, one Surtpl: tactic is just to write

through how u> use the prugTam. 

Each i mi ruction has a code, as for any 
assembly language, also a mneraon.c. The 
mnemonic is what you m:ght consider the 'real* 
instruct on — it in the mnemonic that you type 
in to the computer as a lint of your Redeodc 
program. The initructiciis are dealt with in 
numerical irder of code. 

Each mstru^tiei) iias ekhej one or two 
":irEumi!n[* n the "tuoberc thai follow the 
mnemonic. The largest argument alb wed s 
300C — anything larger will be reduced 
modulus 5000. Negative arguments ate

argu.tifni. of -1 b:eomcs 3990, circe ^ublnic:

cure of 10C0 rantigtious locations, 

— DAT — Used for putting data in a 
location Although this instruction tun a code

of data. Strictly speaking, arty iocatioa in the 
core conratnir.g m unexecuuble stitemer.t 
fallowed by data could be regarded a data 
i; aunit'ai, but DAT is provided to actually 
sore data in specillc 1 locations, it takes ore 
argument. 

1 — MOV — Moves data from one location 
to another. It takes tw-a argumcits, so the 
fflrnut is A4.QV a s b. It will move t ic cunicnl^ 

ofSocalijn j Wi Loc.irion h. witho.it affecting the 
contents of a. 

1 — ADD — This instruction la.^es two 
arguments, which makes its tbntla ADD a,b. 
I: adds die conlftntu oflocHtkn ■■ to the eon:ettts 
of Ircation b, leaving the result as the ne* 
on tents of b, and leaving the contents of a 
unchanged.

formni ii SUB a,b Tl»g cn<;<t h 10 tublraci I h^ 
csntenrs of location a from k>caiioa b, leaving 
the contents of a unchanged. 

4 — JMP — Has but one arcurr.ent, which 
makes its format JMF a. It is an unconditional 
jump to location a usee for ih« aaaic purpose 
as Goto in Basic, but if rclati,'e rather than 
aijso.uiii as exported below, 

5 — fMZ — This is a condit.onal jump 
t nstr action which takes two argumciis, making 

lie term it JMZ n,b. li'llu eonlcnlaof oeaiion 
b is 0, the p'ogiam will jump to relative location 
a — otherwise it will carry on wi h the nen 

instruction after the JM£.

Assumes direct mode 

As 1 buv« jiidj arguments lie id the r*ngc 
0-29?9 whet) assembled, bui in addition, eaen 
tan talu one of tfrce modes, called add rosing 
mod:s. These modes are immediate, direci and 
indirect. Unless you specify :>lh:rwise, the 
compute (..i.iurno ihe irgtment ij ii dircti 

node. Prefixing the aipirrent With^ireans 
i: is itnmediaie, and prefixing with © n.",ea^s 
i. is indirect. Taking as an example the 
complete instruction MOV 0,1 ths fill effect 
would be. 

(lj The computer findi ne.thcr aigument his 
a prefix, so assumes both are direct. 

(2} Ii therefore addi the first argument onto 
the current address » find oil where to get the 
dau to be luai-ed Hon , u j J Llicu wids ific 
second argument onto the current address to 
find oui whert to put it, 

The instruction therefore moves ihe dita 
bcyimr.s r-eyend the insTr.iction — i.e the 
L tt s Uuet i w i iisdf — m * yji^f-iuun 1 luuuiwi 
beyond the instrutiioa Lft. in th: next location. 
Incidentally this is an example or' a complete 
one-Uoc prugrjm — when the instruction htS 
beer executed, the computer ^ill loot for the 
nut ii.auuiiWjM, mid FuiJ ilit uiauuvtiuu 
"MOV 0,1" that has been put there by the 
previous one, and execute this, and this will 
continue, leading t trail of MOV 0,1's 
throughout the care. 

Mac I tii j L-i_iN.it; jj<u^idiiuni;ib will luvc nuked 

thai the direci mode, as are a.l modes, is relative 
— there is no way for a program to know its 
absolute address in the cere, and the sun 
sddresH for each pregram wiihin the cere ,s 
ksvi^jucd ELEtdoiuly oll assetnbliy. 

The other two modes I mentioned work as 
folic ws — first immediate moce. This cause, 
(he argument lo rx_ interpreted at a number, 
latter nan an adcrcsi in core. This means that 
MOV #3,2 will plate ihu ttuntlxf j U; the 
location 2 places tut titer on fmm the present one, 
as opposed tn MOV 3,2- which aoald copy the 
content, of ihe location three places on Son trie- 
present one m:o the Option two on fo>m the 
present out. 

■Indirect mode ,s rather raor; compllcatedj 

and is best cxpHunec by an example.

he is asked to specif" which instruction he

When bnth pUiyers have ilnished 3 you will

When both plsiyers have entered ibrir code, 
it it assembled . If an error such as an illegal 
instruction cr format is cncouuLucU, the 
uprropriaiv player has to re-.nput u.s code. 
Asstuning no errors ire present :n either

and that occupied ty player twn's in gi«n. 

This is the ;irs[ time eitln:r player can know

Geoff Hat to with a 
routine to help in the 
development of a 
program by storing 
and executing 
individual linos 

of Basic text 



This PROGRAM allows irdividuil Easic macros 
— ILies or Basic text — [b be stored end executed 
fmrr wirhir the SEndard editor. This meant that 

you can define simple on? line Basic routines 10

and can be defined, listed, edited and ^ecuted 
usinej a special set of simp!: commands. The 
pro^m also support*, an Olc corntmnd and hts 
\w%i further comraancs for disc drive owners, a 
tctetn directory aid annlmnd string utility. 

The program has been designed » be easy to 
use and has full error-checking kcilities in 
addition to the 5'andard error routines. The 
extensions are in the foim i>f single character

If you execute a macro which causes an error.

then the error will be reported togetyher with

Join the bomb disposal 
squad with Chris 
Turner's Amstrad game. 

1 ,\u Bom r will run en at AmstracJ CPOlfrl 
in uhout 9K. The ubject cftr.c game is to help 
the hero, Arnold the An an hi Et, iind his bombs 
befon ih:y blow him up. You car. muvc Arnold 
U|>. down. left nr fight a square « i time, 
(fHtterali.lg the squire winch he has just left or 
yn[ can flide hist left or right, moving the raw 
lie is on with him and preserving the iintkrljing 
square. All this becomes obvious wtttn ptaling 
ill: pme. 

The Lime left before the tomb explodes is 
shawn as a burning fust ix z.M boi torn of the 
screer.. If :i hrtmb eiplcdes or il be tenches one 
of the skulls which arc spnani libera.ly around 
die scrran, Arnold l«5« a lilt. IT, ho m.->i>r, he 
completes a shetr, Arnold coes or. to the bonus 
stage, litre vow must press the key down when 
he is above the boob. IT Arnold Lands on the 
bomb bo.ius points art gained. 

There should he nn problems typ.ng in the 
program a there arc no lonj Hex dumps, There 
are abain 1 60 bytes ormachinj code, bui these 
arc in nice friendly Daa statttuetiL These lie 
between lines 934)0 and 94/0 and should be v*ry 
caiefiilly typed in if th* rude is us work. Also 
you should bear in mind that Call com minds 
anenaity fellows if the necessary machin: code 
is inn them, :t maybe i good idea to leave lie 
Calls out till :he enc of your tvpir.g, and under 
no circumslarw-fs rim a part oTihe program with 
s Gill in it without first correctly entering ind 
runiiiini [In- program between lines 9300 and 
94 ''O. When ill has been typed tn the program 
car. be saved by jus: typing in:

8S YOUR COMPUTER, SEPTEMBER 1985 



WIN AN ATARI 1 





IN JUKE'5 cortipulilinr It W(1 Atari's J2SK 
comptiitij the I30XE, you wsrc asked :lrsi to 
WtitC 1 plat f*>r a game *vhirh could l»ls*' vlvan- 
tage 0?th: A-ari's eiira memory, ihen to name 
the five worst programs yju ever pdd money 
for. As a prize for the runncs-up ve olie:ed 
copies of Firebird's Don't Buy This [apt, a 
rnmpilaTinnr.f'rh' five vnni program; ever s;ni 
in for evaluation. 

When we set the competition we thought we 
wtuld be able to drtw up a de 1mm ve list of :he 
great software disasi :rs of our rime. As it .urncd 
qui, there wa* almrst nn rin^ns 1* an what i-s 
good and what :s hod. Nc two entries agreed 
on more than one tide. Some pirople even nomi- 
pfi'td suirb than -uppers as uhcstbusttrs, 
Hirrkr Attack* and, Jeff Minier's Gridiuruier 
— in rmrrwik, nneof ih# all-tinR gitais. The 
moral seems :o be that, as far < s games are con- 
cerned, one man'! treat is another man's 
pojmr, ir as the Rjmjns pui ir; Dc gusubus 
noi d.sputar.du.n est. 

If i he re was on*» janm* thai juaUfi^d for the 
title of worst-ever i' was Legend's The Gr;at 
Spjee Race — probably because ii w« so over-

PcSSESSE3isa gmie for tht J6K 2X4J] wrmen 
cn-irtly in machine c<»dc. The game iticlf 

occupies under IK, but Lists tbe full dispby file 
which (iiuori -mainly mEan? the Rsmpack has to 
be fimiy placed on the back of the rnnchin- for 
the game to run. Th; idea of the game is locsdy 

bnicd on Robot ton: yon arz . trtc^nbiinj; — or 
3 C — t-onning anRind shoctinf the robots — or 
Xs — and the highly technical idea behind i: is 
to sap as Diatry robots m possick before foe List 
of you: fire lhies deserts yoLx The gunc includes 
on screen scoring nnd a bcrdc: irtdJcatiiig how 
many lives you haw foft. 

The code is held in tfoiee Rem ttatemcits 
which should b; the .1™ three lines of the 
program. To begin; put the computer in last 
mede, then type 

1 REM. , 439 FULL STOPS OR AMY 

OTHE1 CHARACTERS. ., 

and then slow When entered, Peck 16S53 should 
give J 18 if yam have done this a-riecily. h k. giv*s 

another rumber, add or ickl« ^haraenfrc an 
tieccssiry. N^xl enier the shon hoc loader 
prt'fjram in t'gute 1. This is he sane as any 

noiTJiai hot loader, with two imporunt uddifovis: 

■ totals are entered at the start ol aach line 

rtf rii^K, and 

■ the END address is entered, so the 
computer stops automatically 

Ii'.m error is nude in ciitciing ui.y line uf Lex, 

insieac of displfl>nTt£ the weal, it wiG print Ej 
and you must enter the total and hex again. So 
now er.itir the hex numbers and tOLiI in Ji>rurc 2. 



When you have ftnshcd this, alter the loader 
program st lire 10 i^sds: 
LET A= I03&9 
and line 20 reads 
LET D =17301 

Next, type in a Rem statement at line 2, 343 
characters long — which shoulc return a /alee 
of lia vben 173C2 U I\efeed — and eiiija tl.c 
hex in fi^re 3. 

T.ie final Rem tfatunctir ij only 72 CMKCtefs 
bng, and should be line 3 of you: program. Pteek

once 1 1. is has been, done you will have to retype 
(he digits if you edit a Ihc with numbers in, so 



it's best to use this routine mly when ite
