Joerg (pronouned something like
"Yuhrg") first contacted me about the
time we took over the LOADTSAR Tower.
He is a student in Heidelburg,
Germany, and is dedicated to bringing
together the two Commodore 64 Scenes:
PAL and NTSC.
As mentioned at other times, the
C= world is split down the Atlantic
Ridge. On the west side (US and
Canada), our AC current oscillates at
60 cycles a minute. If you remember
the Vertical Hold nob on your TV set,
you remember when televisions used the
60 cycle pulse of AC to synchronize
the picture. This is the NTSC
standard.
Across the pond in England,
Europe, and stretching around to
Australia, the AC current cycles 50
times a second. Televisions there run
at 50 fields (25 frames) per second,
rather than our 60 fields (30 frames)
per second. The system there is called
PAL.
I would guess that Commodore
presumed that the difference would be
invisible. Indeed, as long as one does
not monkey with raster IRQs, you
cannot tell the difference. But
intrepid programmers (especially over
on the PAL side) got down to the micro
second in screen displays. Some of
their demos simply did not work on
NTSC machines. The opposite is also
true when NTSC coders do impossible
stuff like IFLI, creating a gulf
between Scenes.
And that is what Joerg wants to
correct. He has called me a couple of
times on the phone (a favorite
passtime for him is making
international calls). His English is
excellent (as opposed to my German
which is limited to ordering a beer
and finding a WC -- Water Closet). And
we have shared some international
perceptions.
One question he had was why do our
programs seem to always "paint" the
screen. It is very BASIC -- as opposed
to ML. I explained that we ARE very
BASIC -- since that is our scripting
language. For stuff that MUST be done
quickly or neatly, we use Modules such
as Mr. Mouse or a Toolbox.
At least, that is the LOADSTAR
way. Part of the reason is that this
magazine, while composed of many
programmers by many authors, is one
entity. At best (or in theory), the
reader/user should be able to move
from Menu to Text to Program and back
to the Presenter. That means we are
not too hot on programs that grab full
control of the computer and refuse to
let go. I [do not] like to use the
"Does Not Return" boot!
Anyway, Joerg put together a Demo
group called "People of Liberty" to
promote cross-standard understanding.
About a year later, he published his
first "Talking Disk" magazine -- Scene
World. I am not sure where the
"Talking" comes from; it refers to an
all-text publication on disk. I guess
LOADSTAR is a "Running and Talking
Disk!"
The "text reader" system was
written by Macbeth, our own Robin
Harbron of Thunder Bay, Ontario,
Canada, using Mr. Mouse by fellow
Canadian Lee Novak. The whole
presentation has become quite slick,
incorporating four fonts at a time!
The information is very
international in scope, touching on
the Scene and demo work as it happens
around the world. So we offer Issue 4
of Scene World for your enjoyment. It
occupies all of side 4 and does not
return to LOADSTAR at all. Let us know
what you think. We can bring you up to
date with back issues if you want.
(Issue 2 includes interviews with
Fender Tucker and Yours Truly!)
