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):

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:

   Join 6/D1 and 6/D2, 9/D1 with 10/D2.

   Combine 1 and 2 leg D1 and served there

   At 5/D1 take the signal from 19/D40 13, 12

   Spaevaem 10, 11/D1.

   At 5/D2 served with 2/D46.

   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:

       ^


          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 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.

   The scheme has been finalized with the participation of my
old friend KORUM'a.
