In the online newspaperENERGY #2was published 
Van's article of Fourth about improving computer 
tera "Byte" for working with turbo-loaders 
(for example, in the branded UFO-2) and for simple 
listening to music that may slow down 
zit.  I propose a slightly modified 
improvement scheme, which allows improving 
sew computer work. The diagram is shown   
in Fig. 1.                                 
  The essence of the modification is that the 
the process of disabling the output of information to the computer 
the wound is "hung" on the TR_DOS turn-on signal. 
This made it possible to automate the switching 
tion and reducenumber of malfunctions 
computer when switching. This mode 
switched on by switch SA1.            
  When the switch is in the upper position (by 
diagram) the computer is working normally 
mode. When the switch is in the lower position, 
The TURBO mode is turned on, which turns on 
Only occurs when TR_DOS is running.          
  Switch SA2 is needed for complete 
disable display of images on the screen. 
This mode is used for listening 
music and digitalizations. In the upper position 
switch works normal TURBO-re- 
bench press or computer is working normally 
mode (depending on the position of SA1). In the lower 
This position displays the image on the screen 
stops.                             
                                          
  The only thing that needs to be changed is 
computer circuit - this is to reduce the capacitance 
capacitor C3 up to 15Opf and even lower. This 
required for stable transition to 
TR_DOS and back in turbo mode.          
 The capacitor is selected when 
connected modification.  Switch 
SA1 sets TURBO mode and does - 
Xia transition to TR_DOS. If the computer is working 
melts normally and does not freeze after un- 
Press ENTER several times, then the setting can be 
consider completed.  Otherwise bet 
a densator of a different capacity.                  
  Capacity reductioncapacitor C3 is not 
affects the operation of the computer in normal 
nom mode. (provided that its capacity 
not very small).                          
                                          
 How to find DD10 on a computer board?      
  DD10 is located next to the chip 
giving generator KR5Z1LN1 (then you 
you'll definitely find it).  DD10 has 24 pins, and 
A heat sink is glued to it.               
  Capacitor C3 is not difficult to find. On board 
The serial numbers of the capacitors are written. 
This capacitor is located near the micro- 
hem RAM.
