Nice one

Roy!

I AM WRITING to compliment

Roy Co a te s o n h is Je t S e t

Willy. All the Spectrum owners

(one of them anyway) is as sick

as a dog because of the seven

screens (a t t h e la s t co u n t)

more than th e Spectrum's. I

keep rubbing it into the cuts in

his ﬁ n g e r s ( f r o m t h e

keyboard).

All in all the game is great

and his new game, Bean Stal-

ker, looks just as good and this

just goes to show the Dragon is

far from dead and if you ask me

it's more alive than ever. Like

what N. T. Butlers said in h is

letter t o t h e so ftwa re c o m -

panies, "You support us, and

we will support you."

P.S. I think the Dragon User

does a lot for the Dragon. Keep

up the good work.

Dragon User People's Chart

SHOCK success at the Dragon User Peo-

ple's Chart, as Microdeal's Shocktrooper

again establishes itself at number one,

narrowly beating Juxtaposition.

Much ingenuity appeared in this month's

anagrams, although no one has actually

scored with that elusive x-factor yet. Hon-

ourable mentions go to Keith Turner for his

show slogan 'Race to Osset, spend cop-

pers' and to D. I. Green for his sentiment

'What do dragons like to eat? Lots of chips!'

Dishonourable mention goes to Stephen

Smith, whom delicacy and our legal depart-

ment forbids us from quoting, but thanks for

the chuckle, Stephen. This month's prize

goes to Jonathan Fisher of Huddersﬁeld for

stating the obvious 'Top three games lost in

here', and getting it right, too!

Each month we will be asking you to vote

for your top ﬁve favourite programs on your

Dragon at the moment g a m e s , applica-

tions or utilities, Either list them on the form

opposite or, if you don't want to damage

your Dragon User, just copy them out. To

add that frisson of excitement (as if you

weren't excited enough already) we will

award E25 worth of Microdeal software to

the voter who comes up with the slogan

which tickles us most. Make up the slogan

from letters from your own top three titles

(you don't have to use all the letters), You

can vote, o f course, without sending a

slogan b u t you won't be in line for the

prize. So write, right?
