Did you know ... - Dim SH-shku zero in the port # FF can not. Before recording a # 3D13 to a specific path, if a motor is turned on, and on her head sticking out. How to speed up the process of reading and downloading through # 3D13, If you want to download / burn a few small blocks in a row.

             Did you know ...

   1. That suppress the SH-shku zero in the port # FF
Well nothing is impossible! Sam had so recently done, and
after the run up to a number of troubles. Why sprashivaetsya, 
you can not? Da hell knows, but some controllers after zero to 
the port # FF can only revive the whole pack of assorted 
procedures, even with the Home interruption of all the other 
teams do not always help. Not always possible, and a motor to 
start. In addition, after the zero in the port # FF VG-scale 
sort of believes that she zero road, and then the first call, 
for example, # 3D13, if you really standing on the 
n-dimensional track, and try that Anything with the track 
considered, then plucked trying to put his head on the 
controller 2 * n-ную road, which is very unpleasant.



   As it is better to turn off the motor drive? I'm doing it 
this way: 


   LD A, (# 5D16); Kopiya systemic Regis
                  ; Spectrum

   LD IX, # 1FF3; OUT (# FF), A: RET

   PUSH IX

   JP # 3D30


   It seems to be so safe.


   2. That before burning through # 3D13 by
specific path, if a motor is turned off
and head on it sticking out, then it is necessary to provide 
positioning on this very track. The procedure itself is the 
record plainly can not do, and some drives,

For example, EC-5311, can easily podporot drive. I have 
personally seen it many times! 


   3. What if you ship or send via # 3D13 few small blocks in a 
row, to expedite the appropriate after each call to # 3D13 to 
do so: 


   LD A, (# 5D16)

   OR # 2C

   LD IX, # 1FF3

   PUSH IX

   JP # 3D30


   This will prevent the possibility of a motor to slow down 
between readings, and therefore not will need to spend time on 
his peen. And everything will be cool.



   Actually, I checked the installation # 5D16
Only after the procedure # 05, # 06 DOS. In
other times it sticks out something else
(When and what-not remember. It has long been on PZUshke
climbing).


   That's all for now. If I'm somewhere was not
right, correct me on the pages of Echo!
