        Welcome to the 'iron'!


   At this time we will please
regular refinement of those
do not like sex - a liter ...
Oops ... Sorry, broke ...
Certainly the palette rather than a pint. Anyone who has read 
our Ukrainian zhurnal'FAULTLESS # 9 '

may recall an article about
using bit FLASH for
to create additional colors.


   For those who do not read
briefly explain. Our group
proposed scheme of improvements
any type of computer
SPECTRUM, the purpose of obtaining
complementary colors. Refinement was to replace
FLASH - the generator frequency
14MHz. As a result of the on-screen
where it was before flashing
is not a static flickering
(!!!) Attribute with the new color
For example: white paper + green ink + FLASH in
obtain lime
color. BUT! Color was wondering
for the familiarity, and they
it was impossible to draw a bitmap
pictures.


   I do not know in what ways Sia
script fell into the hands of children from
BIS / RUSH 'ASM but they have developed
idea, and now these flowers
could draw! True
color can be obtained
only on black paper, but
it is enough, believe me.


   BUT! The most offensive that
a break from the first journal to
the latest article I found
Revised scheme.


   And then I began to think. If
is possible, then why
I myself did not develop
scheme. After some suffering. I drew what you need.
Assembled circuit and connecting it to
his "Pentagon" at a
evening. Pleasure was not the end.
Certainly nicer out,
if the orange paint
orange and the tree trunk
brown. So, I suggest
your attention the scheme
Revised computer "Pentagon 128". In lyu6om if
you do not "Pentagon", then you
be found at your pattern
computer register attributes
(Usually a chip IR22
or IR23). If you're not in the Charité
iron, then let you help
more experienced comrades. So
that then I will refer to
scheme for the Pentagon. "


   In principle, analyzing
scheme, you can connect it to the
any computer.


   After you register
attribute is found, you will need to cut a track running
sensitive to the multiplexer
flowers ("Pentagon" is
circuits D46 and D47).



   Cut to only bits
color! This six junior
bit microcontrollers D40.


   At this carnage does not stop, and you need to find
D7 chip on the motherboard and on its
11 feet to cut the conductor.
Continue to collect out scheme:


   And connect it to rupture,
that you made. Inputs on
D40, output at D46, D47.


    Soldered to circuit refinement
clock frequency of 14MHz (m / s D2
One leg) and sample (D40 19
leg) are trying to turn the complex.
Included? If not, then
see installation, can
where a circuit or vice versa
is something you do not connect. If
everything is OK ', then here is this
picture should not be
flashing and the color of a lion cub should
be similar to the orange and
the tip of its tail to
dark yellow.



   If the colors are not so, then
or you need to change
duty cycle, or
proinvertirovat clock
frequency. Bottom of the screen you
available palette. For
the color you need
select appropriate and INK
PAPER and include FLASH. Next
can draw anything.
BUT! Just remember, on paper
familiarity with FLASH'em will
always black. If you have not
is obtained, contact
using the "Zhelezyachnikam" they
help.
