Multicolor

This will give you a stable, compatible multicolor (Scorpio, Pentagon and etc.), plus an unloaded processor. True, it will take up a little space in RAM (6144 bytes of attributes instead standard 768 bytes of attributes), but for monsters like the scorpion, Pentagon-512, etc. it will be unnoticeable. And all this is easy to turn on and turns off (one switch or one bit in port #????. Brief theory Spectrum screen:One 8x8 pixel familiar place has one attribute byte (one tone, one background, one gradation and one flicker). Multicolor screen for given below diagram: One 8x8 familiarity has eight bytes attributes (8...8...8...8...), that is each horizontal line in familiarity has one attribute. Attributes are located at address #6000 (24576) and have the same structure locations as well as graphics bytes with addresses #4000 (16384).

P.S. Attribute switching button (multicolor), developed by Khabarovsk programmer, hardware engineer and hacker Ivan Gromov. Match with material newspapers X-RAY #3 was a pure coincidence (even the attribute address coincided #6000). This on/off button attributes they came up with during the beginning work on the game HEROES of MIGHT&MAGIC 09/1/1998 And we read the above-mentioned newspaper only on December 9, 1998. Ivan Gromov also connected a simm 30 pin 1Mb to a scorpion in March 1997 years (on ordinary mikrukhs) and shouts: - give me a 72pin connector and a 32 MB simm, I’ll connect it via the pro port (#DFFD). - Probably turned it down :).

Now the ideology: SEL1 = SEL2 = 0 Standard mode. SEL1 = 1 SEL2 = 0 Attribute per byte. #4000... #5800 - b/w image, #6000... #7800 - attributes, with bit 6 - the brightness is paper, and 7 is inca. Flash is missing. SEL1 = SEL2 = 1 Each dot is in color. 128x192. Each byte describes two dots: the left one is paper colors, the right one is inc. Even points #4000... #5800, odd #6000... #7800. Signals SEL1 and SEL2 were the 6th and 7th bits of the #FE port, so I did not draw the decoding. Ufff... Bye, Yuri.
