I am spektrumistom with experience. While at home I have the
"Pentium-2, but Spectrum I'm not giving up and not going to
throw. I want to give to those who can handle a soldering iron
circuit expansion of the usual graphics Spectrum to
mode hardware multikolora
1bayt = 1tsvet. Scheme oprobyvalas the "Leningrad-48, 128,"
must also go to "KAY-48 128", "Scorpio-256, 1024.
It all started when I read in
one of the electronic journals for
(Miracle), that the regime is multikolor
three cutting off the board and with the help of
one m / s KP11. I tried to search for
magazines, but apart from anything similar words
I found none. Searched schemes on the Internet -
also found nothing.
For information spektrumistov. Huge
collection of electronic journals, programs, games, music,
etc., as well as links to other sites may Spectrum visit
zx.da.ru. Scheme of Leningrad - site http: \ www.chat.ru \ zrm
\.
Then I took the scheme of "Leningrad", well understand it and
developed one of the variants of this scheme with three devaysa
cutting off the board + a KP11. What
today and write.
Here is the signals for the scheme.
H1-switching to access memory and CPT
Video. (0-CPT ,1-video)
H2 bytes of RAM sample of pixels and bytes
Attributes. (1-pixels ,0-attributes)
According to Scheme 1 signal H1 is the alternate address to
the RAM and CPT video. In a series of handling a video for the
RAM at H1 = 1 is done Sequential sampling of
RAM bytes pixels from the address 16384 (6144
bytes) and the attribute byte at address 22528
(768 bytes).
According to Scheme 2 mode multikolor
includes bit 4-port EFF7 = 1 and made Sequential sampling bytes
pixels from the address 16384 (6144 bytes) and byte attributes
from the address 24576 (6144 bytes). This is verified by
comparing the addresses CPT and Video. In principle, the regime
multikolor can stick on any free port, but I recommend that, for
This standard port - EFF7.
The board made three multicolumn: Cut the track coming to
1D19, 10D14.3, 6D17. The connection is made according to the
scheme 2.
Also recommend to install on your
PC mode the black level (if
it's not), otherwise the screen will be bad
transition of colors.

Will exchange programs and
schemes for iron

Schemes are in the annex to the newspaper
