Flash - The extension of the color palette ZX-Spectrum.

---------------------------------------

  Hi to all! You are greeted far
Cherkassy. Now we talk about global expansion megaproject color
palette of ZX-SPECTRUM. Let's start
first ...

  We read one article from SPARK HG,
which was a great idea: take
Flash, flashing with a frequency of 2 Hz and replace
the frequency at 7MHz. Idea was to
that inverting the attribute is
change your ink / paper very quickly and
result of its color will somehow mysterious. Here we are 
interested in this. After reporting this issue to our 
colleagues - hard'eram classroom, studio "VG". They naturally 
respectively, were also intrigued by the opportunity to expand 
our wretched Spectrum of colors, which, given the brightness of 
16. Well, taking payalo into the hands of our craftsmen in a 
few minutes hooked already adapted Speccy to a color monitor 
(though flashing occurred at a frequency 14Mgts). Well and what 
do we see? Well, firstly, the unusual gray cursor, as there on 
Stand included bits of flash. And when we began to understand, 
then come to some depressing conclusions:


1) Ink on paper is virtually identical (seen only a very small 
difference) with enhanced colors.

2) Keyboard (ink7, paper0, flash1) and (paper7, ink0, flash1) 
give the same color. Because of this enhanced color turns out 
not so much (56, if used, and brightness). 3) Use these colors 
on the practice of is obtained only when the necessary 
disclosure Sit or textured surfaces,

either completely filled with one color.


  Well, you already understand, that in this case nothing good 
from this is not succeed. Well, you paint the picture

frame (frame type of Dizzy) in lime
color and all? Such a thing does not suit anyone. And then 
start working brains ... 

  At the head of our masters of iron comes a brilliant idea - 
to replace a pulse of 2 to 3 (I hope I have correctly put it, 
because I am very far from zhelezopayaniya?) and block the 
flashing of the paper (ie, including paper7 and ink2, we see if 
flash1 on white paper, light red letters).


  The result would be remarkable: the ink we see on screen is 
less than the paper in a 1:2 ratio and that is all

on the same paper that we have established. Ie on the screen 
will be global by The presence of ink on paper, and the 
combination (paper2, ink6, flash1) is not the same thing

combination (paper6, ink2, flash1). Now
We go for simple mathematical
estimates as much ... 128 (!) Colors.

  Well, here is another razgovor.No vsetaki a global problem 
remains. After I get the same orange color can only be either 
paper2, either paper6 Hmmm ... This severely limits the palette 
of colors used, because on a black boom n, which we most often 
use as a background in title screensavers and games

You can only get an additional 14
flowers (again, given the brightness). AND
they will all be dark by some (eg,
dark red). And here is another great idea comes to mind: so if 
zhertovovat, it is better to give names but colored paper. Ie 
needed when the bit flash off the paper at all (set its color 
to 0). And then we have an opportunity for all of your favorite 
black background using the full palette in 128 colors! So cool. 
Although I am now and I can not on the blue river (paper1) draw 
light green crocodile (not fig with green crocodile to be - do 
it green, like all the (very similar to the communist slogans 
:-), but on paper0 I tear myself away swing. And that is all we

received no cost of memory and speed of the machine, using only 
nobody wanted bit flash. Well, that's cool? Are you interested 
in? This rules forever! What remains to add. Revised scheme can 
be found in the log. The scheme is given under computer 
Pentagon128, but in principle You can expand any computer, 
because understand the scheme, more or less groping

person will not be difficult, and having a
hand diagram the Pentagon, he, by analogy,
of course, be able to finalize any
Comp.

  And now a few comments on the revision:
1) If you think that the colors will somehow flicker (such as 
when working with 2 screens), so you deeply wrong - they are 
dead and stable, no flicker or shake; 2) Compatible with 
monitors Xia complete. And even in those rare prog

that use flash in order to
bring to basic'e message "Loading,
please wait! "You just blink instead
see the words of gray, for example, color
(Ie, all the same it will be highlighted, but
slightly differently);
3) to use these advanced color
practice, as you know, the elements can be
packaged in at least the same Art Studio, selecting paper'e 
ink'e and colors that to mix and adding flash;

4) since the previous description of the use of additional 
colours'ov sufficient but it is inconvenient, then hasten to 
bring you good news - Moldovan band Bytex, which makes

Art Works - a new graphical editing
torus, promised to support it this time
processing and a choice of extended colors are much more 
comfortable; 5) Unfortunately the software is not possible to 
determine whether to make a computer conversion, so all will

determined either visually by using
test (flashing or blinking attributes?)
or simply request "Flash-colours - yes /
no ";
6) in our Santa Claus (who DejaVu
and which is Coming Soon) will necessarily
support to cover full screen image of the extended mode (along
with the normal) and CSC-2, even, perhaps,
We will keep these colors in the most
game;
7) Most importantly: in the attached chart to
processing is still a "small" detail -
we decided to abandon the bright ... on paper. Ie paper does 
not emit bright! We are tired of what we do (in the "Robic")

worked properly brightness and because of this
On the screen is sometimes observed in the left am
ributnye squares. And then everything came to a
decision to remove the selection paper. This is even
like and not in the standard, but normally
vyglyadit.No is all due to the fact that we do not
knew, but what's the standard? Well, turns out
It turned out that the standard that works correctly Spectrum 
bright (which is not at all) is as follows: bright'om

allocated and ink and paper. But in a unique
noi the case when the paper is black, is included
Naya brightness will not be to the paper
(Distinguished black only)! So that is where the dog you are 
zarylas.Mozhet and knew, but unfortunately we do not. And now

why the proposed scheme is fully retracted selection paper'a
bright'om. But the man who in the course
cases where poking payalo can elementary
but remove this joke.

  And finally a few words, some of which are for publicity 
purposes. 

  If there is something you misunderstood, could not
make, etc., then you can always call in to the studio Cherkasy 
"VG" and learn something you are interested please call: (0472) 
64-33-48 or (0472) 64-0536 (from 9.00 to 17.00 ). And also, if 
you interested in computers Robic (without extra

modesty say that after all the improvements - it is really the 
best among the existing complex at the moment (it Of course, 
just my opinion, Slider'a, but it coincides with the opinion of 
many of my friends) with extended 1MB memory (2-x Ports - 512k 
switches on the standard port 32765, and the rest - at the port 
ATM-TURBO), and full compatibility with Pen tagonom on all 
parameters (!), then you can also order them yourself on 
vysheuka zannym phones. Cost megabyte

computer, fully developed
(Including flash-colours) - $ 40. And of course
We can potsepit yourself to this component
vserazlichnye drives and their controllers,
screws, digitizers (8 gradations of brightness,
standard video), etc. So
call, ask, ask, order ...

  At this point I'll say goodbye. Bye. And the last. Your 
comments, suggestions, etc. Section taken at: 257005,
