   In the second letter that came to me from
Russia, there was this text. There is little benefit from it
reading, and even more so application, but also
no less than many of my friends on the spectrum
mists and even one pisyushnik at one time
suffered from similar amusements, so I re-
I wanted to place it completely. Hackers! This
for you... If you don’t learn to la-
mother of the program, then at leastSTS`
please use it :)

 This little article is designed to help
for novice hackers when opening some
protection To use the following
information, you need to have a basic knowledge
knowledge of assembler and have some skills
working withSTS`. Good luck!

   1. Download the program to be hacked and
set current in cell 23796/23797
sector/track.                              
   2. Install the PC at address 23924.       
   3. Call up the TRACE menu, turn everything off,
except STOP if DOS and TRACE CALL, do
GO.                                       
   4. Set a breakpoint at address
16686.                                    
   5. Execute JP at the current address.    
   6. Go through a short xorka, after which
costs JP.                                 
 7. Having completed it, you will be protected
the desired program.

You are ready to go to 49436.                     
   5. Set PC to address 49290 and go
step by step to the protected program.

   3. Go step by step until 28255.           
   4. Call up the TRACE menu, turn everything off,
except STOP if DOS and TRACE CALL, do
GO.                                       
   5. Restore the resident, install
breakpoint at 20505.           
   6. Execute JP at the current address.    
   7. Go through a short xorka, leaving
it, you will find yourself in the protected program.

   1. Set CLEAR to 25999. Download
hackable program using the command
MERGE.                                    
   2. Install the PC at address 23884.       
   3. After passing 3 xorks, put a point
Tanova at 57163.                   
 4. Execute JP at the current address.    
   5. Go to address 57508 and remember 8
byte from address 23781.                      
   6. Record using the SAVE TRACK function for 1 sec.
tor from address 23867 to sector and track to
23787/23788.                              
   7. Change the data in DISK DOCTOR
file head to those previously remembered.       
   8. After this the program can be easily
copy.

for everyone who is seriously involved in defense -
mi and programming.  It's pretty here
the method of auto-
tarting disk.  This is how they are launched
iS-DOS, Mortal Kombat, Field of Miracles, Black
Raven  and many other programs,
sweeping the entire disk. WITHon the one hand - not bad -
high protection from stupid idiots; on the other hand -
programmer class. So, let's read.

   Before any operation with a TR-DOS disk
loads the ninth sector of track zero into
a buffer specially allocated for this purpose
address 23845. The buffer is 257 bytes long.
Comrade  Behind this buffer there will be an area
channel descriptors. TR-DOS cannot
steal part of the sector, it loads its targets -
com, whatever length it may be. As a result-
those sectors longer than 256 bytes,
overwrites channel descriptors. But TR-
DOS does not know about this and tries to identify
copy disk. First of all shechecks
in this sector the byte is at offset 231, and
if it is not equal to 16, then immediate
interruption of the operation with the issuance of a message
Messages Disc Eggrog.Message is being issued
through channel K. This is where it works
autoloading mechanism. Enough for cells
with offset 257 and 258 write down the address of your
our bootloader, which is located in the volume
same sector. The bootloader will start, and then
do what you want.
