READ THIS CAREFULLY !!!!
PROCEDURE :
1. backup EEPROM content first !
2. solder adapter pins to radio :
GND on radio GND
SDA on 5 pin of EEPROM
SCL on 6 pin of EEPROM
Power control - on 45 pin of MCU
+5v permanent - on 64 pin of MCU
work/NOT work - on red connector of tape deck (picture)

3. load tape deck manually
4. connect adapter to PC
5. turn radio power control into OFF position
6. start program ( for port initialization )
7. put power supply 12v to radio
8. press START button
9. wait :))
NOTES :
1. Minimal searching time ( up to 1999 ) - 50 minutes.
2. This program runs only on Pentium (and higher) computers,
sorry . NOT run on 386 and 486.
3. You can make adjustments of some parameters - range of code
(up to 1999 or to 9999); I2C delay - from 1 to 30 mks;
Initial code ( if you want to stop program , it remember last code );
waiting time - from 1 to 4 seconds ( this is time for waiting
after power on )
4. All other buttons in program - Power ON, EEPROM R/W,
Reset counter, Code ON - made only for debugging.
It is not necessary to use them , but if you want ...
5. You can minimize this prog to tray while it searching for code .
It automatically popup from tray , when find code.
6. You can use 'Time Critical Priority' (find in system menu of program),
but it is not recommended, because all other tasks in Windows
greatly slowing down. Use it if you have strange errors in
reading EEPROM content.
7. When you use small waiting time ( e.g. 1 second ) you
also can find code , but it can be greater , then real.
After this try this code and one or two smaller codes.
8. Automatical resetting of $EE cell .
ONLY for carradio-decoding members !
