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

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.
