Flash - The extension of the color palette ZX-Spectrum.
Topic: Flash-colour Author: Slider / BIS / RUSH 'ASM --------------------------------------- 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, Cherkassy, ul. Shevchenko, D. 367 / 1, Apt. 37, Bezuglov Andrey (Ticklish Jim'u). Tel.
