After 10 minutes, it appeared before my eyes black hearse, with a small box inside three and in white letters: Here lies the child of Clive Sinclair. Eternal memory to the heroes. 1981-1997 The clouded mind came with difficulty back to normal, hands, with an iron grip, grabbed sitting in my native Spectrum, exhaustedly lowered- and the user understood that he wouldn’t do it next time will endure and the pc will take his sacrifice... All this is to say, stop mocking me. above us - to frighten us with quick death without hope shield Specky. Let's better take our eyes off for fromscreen - and we will understand that life is about should. And finally, with a sober look, read the following article: GRAPHICS FOR SPECCY. WHAT ARE THE PROSPECTS? It seems that since the birth of Christ conversations are being held, the essence of which is The point is that Spectrum is dying, moreover, th, clinical death has already occurred and all messing around with him is a perversion of a bunch of fans. Os- putting aside philosophy, sophistry and other exact sciences let's deal with technical analysis of the problem, or rather its part - ZX graphics capabilities. It's no secret that already at the moment birth SINCLAIR did not amaze with his graphics technical capabilities, did not particularly shine even among his competitive classmates Comrade Of course, the schedule also had its own know how (notorious and well-known third of the screen, original text-graphics chy mode, low color resolution, well, and most importantly - simple and quick access to the wound). However, much has passed since then beer, and everything that can be squeezed out of it whether. A natural question arises - what? next? It arose for me too, and back in times of carefree childhood. Except me Others were also interested in this issue. faceful people(really modest?). However, experience mastodons (ATM and Profi) was not successful and the answer is obvious: their grandiose accomplishments could be used by a narrow circle of restrictions valuable users (pun intended) and naturally have any tangible impact on the progress of the ZX evolution could not. Soft for them was created, and if something appeared very small and unsightly, without receiving neck spread even within its own subplatforms. As one bald uncle once said, we let's go the other way, namely: any appa- reverse improvement of graphical capabilities capabilities should be covered without much effort Vat the entire ZX 'Jurassic' park. At the times described, I studied at BPT (is the Best of high school of federal district Borisov) and received some un- extensive knowledge in the field of hard work, which helped me look at the problem from some perspective swarm of shares of healthy professionalism. At that time I professed the principle of simplicity and believed that a device of this type should connect to the machine (guess which one (if to the washing machine, you win and can read no further)) most to any programmer, user, lammer, gamer & others was able to upgrade with minimal using thermal effects (i.e. soldering iron). By observing this postulate I hoped to attract under the banner of the great mo-soddenization whole crowds of happy posses- ZX-SPECTRUM. Oddly enough, I developed a similar scheme botal (on paper, so as to translate it into iron there are no means or experience in debugging and schemes, not time (dark and inexorable diploma was approaching). So the idea remained crystal dream Briefly about the essence of the matter. Connection diagram went to the car with six (6!) conductors (along with food), contained about a dozen We have inexpensive cases plus additional video memory (eight K5b5RU7 or SIMM quarter, which is even cheaper these days). servicing additional video memory practically no resources are spent computer (i.e. the bus does not load and does not processor slows down). Access to additional solid video pages are no more difficult than for example, access to an additional screen in 128 cars, and strictly as needed mileage. In this way it is possible to implement division of the output image into color commercial planes, which is convenient for example for titles, etc. Brief technical characteristics: Resolution 256x192 Flowers per point256 Video memory capacity 256K Organization of video memory ChxbChK All video memory is divided into four pages, each page is divided into seven color planes, access to each of which is arbitrary (at the same time it is possible work only with one color plane - yu random page) I remind you that the described device exists so far only in the form of an electrical circuit critical principle (PE 3) and any interested, and most importantly capable of it debug can count on cooperation quality. Now another flint in this a small spoon of honey. This scheme is not used overcomes another Sinclair limitation - relative low power of the processor, i.e. I doubt that he will pull a full-scale early multi-color graphics with acceptable speed. On this occasion we need to drink and have a bite and then rush to collect a new one scheme option. But seriously, I have there are developments in 2D and 3D hardware acceleration viewers (you guessed it, of course: N is taken chips like K155LAZ and DOOM runs like on Pentium (just kidding)). By the way, about DOOM - there 'runs' no more than 32Kb, however 'even- Verka' is loaded almost completely, i.e. withoutadditional hardware tricks Sinclair will 'sweat' driving such arrays data, not to mention the calculation work 3D graphics. Count on serious improvements You can create graphics (and especially 3D) only by using EU hardware acceleration if it’s very serious, then if you wish, you can figure it out and pour Gouraud into half a dozen microcircuits of medium degree of integration, which will add a few bucks to the total price. In short, if anyone is interested in this and not everyone is deaf, then call, write letters, send telegrams, parcels, parcels, fact- sy and just messengers. You can contact me- but through COM1 in slave mode, and if so very seriously, on the phone in Borisov (by very big holidays and weekends) 9-51-65 Oleg, or in Minsk 231-94-27 Zhora. P.S.Thanks very much to Pavlov D.M. for those technical support for me after everything was discharged that beer.
