This article is a logical prodolzheiem articles from the last
issue, where he gave the scheme expansion of conventional video
mode Scorpio. This once I give the same scheme for
turbo-Scorpion.

All designations for chips are given a green card
Scorpio. For yellow you can try to take the scheme
Green Scorpion, in principle, they should be similar (only the
turbo-charges). Before the slash indicate the number of chips,
after - the number of output.
The following conclusions circuits must be disconnected from
the board or cut the track so to have been disconnected only
those conclusions and only those chips!
D3 / 6 - H2 IE7
D17 / 6 - ADDRESS SCREEN KP11
D33 / 3,4,10,11 - VIDEO KP13
D34 / 3,10,11 - VIDEO KP13
D39 / 7,15 - REGISTER IR10
D40 / 9 - REGISTER IR16
Advanced mode is enabled by setting the 1 st bit
(Counting from 0-th) ports # EFF7. In Advanced mode, the screen
color is determined by the color of the curb, and color
assigned points to 0 or 7, depending on 2-nd bit color border
(counting from 0-th).
If the color of the curb is in the range 0 .. 3 is the color
set of points will be white, otherwise
- Black.
Half of the images is located at # C000 and
is # 1800 bytes. The other half is
at # E000.
The image can be in the fifth or seventh banks
dependence on third-bit port # 7FFD. Symbols on
alternate screen - one in one half and the other
- In the next.
If the screen will disappear individual pixel rows
(vertically), then try to solder a capacitor to 15 foot D39
capacity somewhere up to 750 pF (or more, I had put on 750 pF)
