An Editorial
Our fi rst and only Editorial in Commodor e User — it's not
something we want to make a habit of, but it makes sense to take
a few words to introduce this inaugural issue of a brand new
magazine.

Commodore Show takes over Hammersmith on 9-11 June. Read
how t o get ther e and what y ou'll End o n the stands — a

the complete stand plan, and a full run-down on the exhibitors
(not to mention our favourite local eateries and pubs ) ...

Holiday with a computer?
65
The truth about part-time software millionaires. Adtian Jones
spoke to some of the prospective purchasers and publishers for
your brilliant programming: what do they want? And what do
you get in return? But then Chris Preston draws on some hard-
earned experience for the other side of the coin . .
Computer-based 'activity' holidays are sprouting like freckles
on a redhead in the Summer. We located a dozen of them and
asked the pertinent questions — what they provide, when, how
much.
Radio Ham with a Vic
Your records on a microcomputer?

As it happens, keeping records is a natural for the computer
and now there are many low-cost computers with relatively
inexpensive software packages that will provide you with rather
more than an automated fi ling cabinet. We present a beginner's
introduction to the subject.

RTTY on the Vic? Amateur radio enthusiast and Vic expert Mike
Todd offers a tour of the possibilities, with reviews of the RTTY
packages we could fi nd on sale.

Writing i n as s embler language i s s uppos ed t o pr oduc e
programs that r u n faster than thos e i n Basic. But it's als o
supposed tobe considerably more diffi cult. David Pinless starts
a six-pan novice's guide to assembler programming; and to set
alongside it we have an impressive demonstration of the speed
difference.
People who write Basic programs on Commodore computers
will k now the virtues o f instant assistance — automatic line
renumbering, changes, deletions and the like_ M ik e T odd
looked at four for the Vic, gives a full review on each, and rates
them on value for money.

Super SIDI

But if you stick with good old Basic, the language that is built into
all Commodore machines, y ou c an s till d o 'it better. Chr is
Preston unfolds the not-so-arcane mysteries o f 'structured'
programming.
Colour on the Commodore 64 is pretty good, too — but even
more impressive is the 64's built-in Sit) sound synthesiser chip.
Kent Multer gives a guided tour of SID, shows you to how to get
the most from the 64's sound, and suggests some clever uses for
it.

2 C OM M OD OR E US E R
Welcome to the first issue of Commodore User, the new magazine for everyone
who has an interest in getting the most from Commodore computers.
Commodore User comes from the Paradox Group — small,
Independent, but above all specialised. You may know of us
from Vic Computing, the magazine dedicated to the Vic-20: but
that is only one of our titles devoted to specific microcomputers
and specific uses of computers. To put it simply, we specialise
in writing about small computers: and we specialise in writing
about the practical uses of those computers.
We run such computers ourselves both for business and for
pleasure — so we know what we're talking about.
And w e know w hat you w an t to read about. W e b u y
additional hardware, software, and services; we write and use
programs; w e have to struggle with the same user manuals
that you do; we have all the pleasures and problems of the real-
world microcomputer user s o we know what the user wants
to hear.
Commodore User will reflect all of that. We will be covering
the full range of Commodore products — though our bias will
naturally be to the mass-market sellers like the Vic and the
Commodore 64, where the sheer range of options for the user
and the variety of possible uses justify the presence of an
authoritative commentator a n d educator l i k e t h e n e w
magazine. W e w ill not be neglecting the 700s and 8000s,
however.
And w e don't regard the 'best' commentators simply as
those that know what they're talking about. We also demand
that t h e y c a n exp ress themselves art icu lat ely; t h e i r
contributions are readable as well as knowledgeable.
That's the third point — Commodore User will be a good
read. We' re not trying to produce a reference book o r a
technical manual. So we spend money on the design of the
magazine, trying to make it look good and trying to make the
format suit the information. W e spend time revising and
editing the articles, ensuring that the writing style makes the
subject comprehensible (and maybe entertaining too). We
plan our issues for balance, covering a variety of topics and a
range o f different levels o f knowledge s o t h at there's
something for everyone in each issue.
We care about w hat w e do. An d , u n like some micro
magazines, we care about what you the readers want.
How and when?
So what sort of magazine will you be buying?
This is the pilot issue of Commodore User. We have taken the
opportunity o f the Commodore Show t o incorporate t h e
Official Show Catalogue in the new magazine before our
official launch on the newsstands: that gives you the chance to
see what we'll be doing, and it gives us the chance to sort out
the look and content of Commodore User for the future.
From the Autumn you'll be able to buy Commodore User
every month at bookstands and newsagents as w ell as on
subscription. The cover price w ill be 85p. We are printing
around 70,000 copies of each issue and we're aiming for an
average of between 60 and 120 pages.
Commodore U s e r w i l l incorporate V i c Computing, o f
course, and existing subscribers will find their subs honoured
with the new mag; and we'll be extending the coverage to
include the other current and future Commodore machines —
like t h e hand-held computer, t h e portable 64, w hatever
replaces the Max, and so on.
We start from three premises. First, Commodore User will be
useful. That means Commodore User will not be abstruse and
technical: our articles will cover a good range, but the stress
will be on practicality and general relevance to the bulk of our
readers.
Second, Commodore User will be authoritative. We have
already signed up some of the best technical columinsts to
explain the idiosyncracies of the Commodore computers, to
answer your queries, to reveiw the kind of add-on products
you should or should not be considering. To help you get more
out of your acquisition, in fact.
Launching a new magazine is always a gamble. But we know Commodore
user will be filling a need: and we're sure that we will produce the kind of
magazine you will want to read. With your support and our confidence
Commodore User will be not only one of the most useful publications on the
newsstands but also one of the most successful.
