(C) RED ALEX
Tale of 128 colors
(For Scorpio and his ilk).
Greetings, dear readers.
Now one Red Alex pushes the masses
delusional topic in sabzhevuyu scheme:) True,
have been similar schemes in the Miracle # 3 and RUSH
# 1, but you do not hurry to press the Reset:)
Why, you ask, we should not these things
do? And therefore, I will answer that my scheme
much easier in terms of iron, ie detalek
we need less. Plus, this will not have to
on the board to arrange a surgical war:)
So, we proceed to describe. We must
m / s LA3 any TTL-series (155, 555, 1533),
switch type P2K (who is on
the sides to 6 feet sticking out:), three resistors
MLT-0.125 (can be powerful, but it's not:) under
1-1.5 ohms, and of meter MGTF-a:) By the way, rezyuki should be
the same denomination.
Scraped together all of the above? Then
quickly down to business, comp cut down safely :-) And
Cutting the pair of tracks (or wires,
or whatever you have) on the board.
Here is a drawing for a yellow card Scorpio.
All we need mikruhi signed:
quartz
ZQ D41 | D42 | D7 |
14MGts VD4
+
D2 | D40 |
D33 |
But the figure below for a green card
Scorpio, where necessary melkuhi also noted:
quartz
D2 | D7 |
ZQ
+
VD4
- D40 |
D
42
D43 | D33 |
Further, the whole numbering mikruh given by
yellow dress Scorpion, because I have such.
For Green, see below a table of correspondence:
yellow green mikruha
D2 D2 TM2
D7 D7 IE10
D33 D33 KP13
D40 D40 IR16
D41 D42 TM2
D42 D43 KP11
So, what is cut? We find m / s D42 (KP11) and cut the track
from its 15th leg, leading to the D41 / 8,3. Only
more careful out there and do not accidentally cut the
road between the 8th and the third leg D41 (it
must remain whole!)!
The second section ... Find m / D7 (IE10)
and cuts a path between its 11th leg
and minus the diode, to which she goes. Diode
this - VD4. Remember him, he told us afterwards
More useful:)
Everything on this road carnage is over:)
Now comes the stage of soldering. We take our
LA3 and collect the following scheme:
D33/13
555LA3
D40/10
May 1
2 3o 4 6o
D41 / September 1910 D42/15
9 8o
D2 / 3
December 1911
14MHz 13 o
To minus the diode VD4
(The same one to
tory I asked for
Remember above. Tue
of the output diode
goes to the D11 / 2).
Here is a shemochka ...
So, if you are building on the yellow Scorpion,
the best thing our LA3 hang on top
D41, except for good food match, and the 9 th
feet. If you are building on the green, then our
LA3 rewound to the mounting box next to the quartz. All wires
are obtained by the minimum length.
If someone is strongly needed, you can put a switch to turn
off our 128 -Color. The truth is whether this devaysa I do not
see the point. How long has yuzayu, and never turned off.
Although ... :) Can who may come in handy ...
So, to start picking up the wire
between the D42/15 and the eighth leg of our LA3. And between
the 11th leg of our LA3 and minus diode VD4. Take the button
for the type P2K, or any other similar design and assemble (not
chaos, but one that at the bottom:)
| P2K
/
D41 / 8

D42/15
O
(Our) LA3 / 8 /
O
D7/11

(Our) LA3/11 /
O to minus diode VD4
(The same :-)))
In short, if disabled the button, move the old signals
(which we cut), and when pressed - the new, which is obtained
and 128 colors. Not all the time, of course :-) If you do not
use the 7th bit of the attributes (FLASH), will be the usual
color. A palette of 128-I obtained if bit 7 = 1, ie attributes
of 128 to 255.
A little more about the schedule: when the
FLASH'e 128 colors is obtained only at
INK'e and PAPER should be black as moss ... Oh, like an eel:)
Why do we need the solder to the board on March rezyuka 1-1.5
ohms. Rezyuki hang on signals R, G, B of m / s D42 (4,7 and 12
feet) and land Very convenient to hang directly on top of the
mikruhu. In the absence of ballast, "paper" with new colors
will be like a divorce, because of the smoothly decaying INK'a.
Fewer resistors should not be followed, would squander the
color (and brightness).
When mixing colors PAPER should dominate, ie, INK white on
black PAPER should be darker than black on white INK'a
PAPER'e. If you have proved otherwise, remove the 14MHz with no
inverter LA3, and directly with board of D2 / 3.
Yes, the "original" mixed scheme
7MHz and 14MHz. I tried to do it ...
New colors are almost identical to the standard! Can check
yourself: 13th leg Our LA3 not connect with the 12 th and Throw
at D2 / 2 (7MHz). Is it going to And this for the sake of the
scheme? Do not believe it! (C) Stanislavski :) So Miracle # 3
diagram of the "correct" :)
Finally I will say a few words. The newspaper KrNews # 11
the authors wrote, that have developed such a scheme, one
mikruhe. I suspect that I have the same ... In this connection,
I declare: Maxx, VTS - I did not steal from you have this
pattern! :) However, KrNews # 12, which promised to publish the
scheme, was not yet (?)... But if my article will be released
earlier, then no problems will be:) K Besides, I worked this
miracle in the last year.
And to put to rest any suspicion from himself:) I will say
this. In KrNews was a postscript, that, well, not at all
complex scheme works equally well (gives the same color). Well,
I declare that no scheme, although "classic", although this
does not provide the identity on different machines, even on
two identical Scorpio, for example.
But the point is all that signal FLASH
taken from the 14MHz, which is the frequency of the quartz in a
computer. So, meander signal y we are unlikely to get an
equivalent (ie signal equal time to "0" and "1"). A
all because of the different resistors and chip
generator, and quartz, in the end.
Therefore, on one comp mixture of green and
Red will brown, but on the other ... Even
I do not know:) No, the difference will not be fatal, but
that's flowing "play of colors" such longer seemed unlikely.
In addition, each component are its
rezyuki to RGB and BRIGHT. And even a connection
to the box is made from all different ...
Anyway, nice to intimidate you:) Even though the desire to
build a scheme you would not have gone after all
vyshenapisannogo ... If this edition does not carve;) Hope
no. We have, in any case, this fichey
equipped for 4 companies (starting with mine, ofkoz:), and
everyone is happy and jump for joy:) It remains zayuzat Santa
Claus under this case, and while you can admire the young lions
from Miracle # 3 :-)))
