PORTABLE POWER?
After years of writing books on computers
and awarding his famous 'White Elephants'
to the industry, Adam Osborne finally took
the ultimate step and produced the
Osborne I. Despite the fact it is portable,
well. almost, and fairly reasonably priced
as hardware goes, the main attraction seems
to be the fact that you get several hundred
pounds' worth of software thrown in for free.
Having humped the system up hill and
down dale and generally put it through its
paces, our reviewer will hopefully have
recovered sufficiently to put pen to paper
and report on his findings.
SIMULATING FORTH
The interest sparked off by our recent series
on FORTH has been so great that even we
were taken by surprise. As a result, next
month we'll be publishing a rather novel
BASIC simulator for FORTH operations so
those of you who would like to try out the
language — without actually having to buy
a version of it for your system — can have a
go. It certainly won't break any speed
records, in fact it is extremely slow, but it
does allow you to get to grips with Reverse
Polish Notation.
PROGRAMMERS' TWO-
STEP
OK, so you've learnt to program in BASIC.
Now, perhaps, you'd like to have a go at
assembly but you're put off by the fact that
you can't alter your programs with the same
ease as you can in BASIC. Well, what you
need is our two-pass assembler which lets
you write and modify the assembly code first
and then turn it into machine code without
destroying your original.
.So, if you'd like a professional software
tool to help you with your assembly
language programming, don't miss out on
our next issue!
ARE YOU SECURE?

preparation but circumstances may dictate changes to the
final contents.
Or, to be more precise, are your programs 9
In our next issue we'll be taking a look at a
rather clever method of program protection
which actually allows your programs to be
copied but then won't let them run on any
other system frustrating in the extreme!
We will also be publishing an extremely
ingenious Voting Loader which guarantees
perfect loading from cassettes at almost any
speed. So, for your own peace of mind and
the security of your programs and data,
make sure you secure a copy of our June
issue.
