Iron - another version of the circuit 128 colors on the Spectrum.
(C) KOOLL 128 colors! I know that the first who suggested the use FLASH to create 128 colors was Journal FAULTLESS # 9, but the scheme was crude. Further RUSH mentioned the Modified circuit flowers and, like me, we know the scheme was not published. It was a statement VTS / TL o scheme pozvolyayuyuschey get 128 colors for all computers, but it was promising, the publication scheme in the next room was not. RED ALEX / MIU / CTL sent VEL'u scheme for SCORPIN'a 128 color'ov for yellow and for a green card. After last night, it's safe to say that the 128 will PENTAGON'a 128 colors. And not just the Pentagon, and in any Spectrum-compatible computer. The foundation of all improvements - scheme of RED ALEX'a. Had to add a single chip for the implementation of additional palettes (the difference in video controller), and because of this scheme was universal. Are cut only two tracks (if you honestly say, three - one in two places) with the if the guys from SPARK'a cut almost sex com. There is another scheme where Roads cut, no less. I declare that the diagram below OR -WHERE AND NEVER PRINT, so are the intellectual property CONSTELLATION ia Proceed directly to the scheme itself (The scheme is given for PENTAGON'a 128, below will be considered the question of how to connect it to other companies): 19/D40 1 3 '5' 6 LA3 LA3 ° ° 2 4 6 9 10/D42 k13 1 ° January 1910 LE1 LE1 4 ° 2/D46 May 8 9 B1 13 '8 '° ° LA3 LA3 Oct. 11 K 1,15 / D46 12 1,15 / D47 B1-taken with the resistance R16 it is between two chips KP2 (KP12). 1) break the track, going to 13/D7 so that communication with the condenser was not. 2) Solder the posting to the site after gap and the 2 nd leg D1 (LN1 stands next with a capacitor). 3) we find the board resistance, which stands between the two KP2 (12), from this resistance to depart two lanes going on different chips, cut so that legs 1,15 / D46 and 1,15 / D47 stay connected. 4) connects the two mikruhi wiring D46, D47 first leg. 5) collect a chart showing how this I have done: 10/D42 Q1 1914 January 1914 with an R16 K8 K13 D2 19/D40 D1 2/D46 ∙ ° ∙ ° 1/D47 Turn down all legs, except 7-bit and 14-x napaevaem them at each other and to pripaevaem D41 (IR16). Join 6/D1 and 6/D2, 9/D1 with 10/D2. Combine 1 and 2 leg D1 and served there signal 10/D42. 3, 4, D1 interconnects. At 5/D1 take the signal from 19/D40 13, 12 feet and combines this compound served siganl with R16. Spaevaem 10, 11/D1. At 5/D2 served with 2/D46. C 8/D1 remove the signal at 1/D46. If you need to reset position then do the following: | P2K / the condenser C5-rupture O after the break or 13/D7 O 2/D1 / O B1 with rezuka R16 O 8/D1 (revision) O / O at 1-enogi micro schemes D46 D47 After all these operations, you become owner of 128 and flowers. I want to say that options schemes for Pentagon much, here's one - the most optimal: FLASH BORDER 1 ' le1 la3 ° ° ' INF la3 ° the old B1 'place B1 la3 ° 1,15 / D46, 1947 ^ and instead of the element You can put elementik to LE1 FLASH - 19/D40 BORDER - 2/D47 (46) INF - 10/D42 B1 - from R16 Indications for PENTAGON'a. The principle of operation and how to do it on another machine: 1. FLASH signal changes INK on PAPER. So, the principle of the scheme at this and made. At the beginning of the scheme RED ALEX'a. FLASH signal goes to the element LA3 (AND-NOT) on the same element comes proinvertirovanny INF signal to determine O PAPER'a. Further, this signal is another AND-NOT, where so-well received inverse signal synchronization mixture was then and quenching occurs PAPER'a. But in PENTAGON'e at the same KP'shkah switches colors BORDER'a and SCORPION'ovskoy scheme to curb output picture. To remove it, we it took another chip LE1 (OR -NOT). It blocks the FLASH mode during output curbs videokontrolerom. 2. To implement this scheme in another competence in the first place to find the generator at 1 Hz (FLASH, flickering, changing paper color on the color dots), the output of this generator to cut and serve after the cut 14 megahertz with a master oscillator. Find the signal INF, it is usually formed to the shift register (IR16, IR9, IR10). Enable signal for FLASH without WAIT ' marketing can be found at IR23, the 19th leg, and the WAIT'ovyh machines at the exit KP11 (KP13) leg of the fourth. Find KP2 (KP12, KP11), which form RGB signals and cut off from them Enable signal (synchro) for KP2, KP12 a foot 1, 15 so that they remain connected, and at KP11 - 15 feet. And collect the RED scheme ALEX'a: FLASH '' LA3 LA3 ° ° INF syn ' '° ° LA3 LA3 on the resolution of KP'ek. If on the curb you have started to come out any garbage, then collect our scheme for What you need to find a signal BORDER. If you have a KP13, it is taken with the 13th leg (the Pentagon K13). WARNING! On some machines, such as PENTAGON 3, this scheme turns white PAPER. On other machines, the scheme was not yet tested. On some machines noticeable shift from normal video mode to 128 colors. date: 8.10.Y2K time: 20.00.83 The scheme has been finalized with the participation of my old friend KORUM'a.
