Iron - FLASH-color scheme for the simplified scheme.
_________________________ FLASH-colour _______________________ I decided to show you all the same scheme for flash-Colora a simplified scheme. First it there like a gamah gathered support, and secondly it to anybody is not needed (no one has asked), because all sorts of tricks that should would modify its I will not do ... Explain that it and why there is not 128 colors as promised, so I do not I know who has what colors are, I do not I will - all the same boring and uninteresting (Who wants to let himself think of how these colors are mixed and how to walk off ratio 14mhz ...). This scheme is only complete functional analog of the famous Mount multiplexers. I'm just sick to think that with the release of Gama porezhut though a Spectrum. In my scheme of improvements minimal. She works for a year or two. By the way, CGA monitor from FLASH breaks off ... Well, the last reason why I bring the scheme - should be something to fill KrNews :):):) [A] k: 10/D41 a D1 '-K1533LA3 s: 10/D40 'March 4 o '6 [B] 2 o k: 12/D34 5 9 8 s: 13/D33 12 'o 'O [C] October 11 k: 11/D42 13 s: 8/D42 x> k, s: 15/D43 [D] [E] flash (1 Hz) x> [G] k: 4/D1 k: 9/D13 s: 6/D1 (14Mgts) s :(-)/ VD5 [F] Legend chips are given by the scheme KAY-256/1024 (k) and the Scorpion-ZS256 Turbo + (Green) - (s). We must cut the two roads mentioned sign (x). The scheme is tested for KAY'e on Scorpion'e possible problem because of the implementation element "AND" diode (VD4, VD5, R54)-R54 can also try to reduce to 1-2 ohms, and better delete (VD4, VD5, R54) and put normal K1533LI1. K555 series put undesirable, K155 simply impossible. Description of the signals for implementation of the regime on other machines: [A]-out IR16-pixel information to drive the multiplexer INK / PAPER. [B]-bit FLASH to register attributes. [C]-quenching of the beam on the reverse Horizontal and Vertical. [D]-blanking input / output beam OE output multiplexer (KP11). [E]-by generator flash 1-3 Hz-cut. [F]-generator of 14 MHz. [G]-input from the generator flash. Briefly describe the operation principle. Replacing flash-generator at 14 MHz provide mixture of signals INK / PAPER in one color (Ie 6-bits + BRIGHT!). Now, this color will draw on a black background, for this will extinguish the screen when turned off pixels, ie pix = 0, Flash_attr = 1 and introduce this mixture into a quenching of OE/KP11 (Ie, quenching -1). That's all.
