Hi,

before I found this forum I have used kitsrus 151 programmer(www.kitsrus.com & it's PDF) and it's software. It works through LPT port. I totally unsoldered my chip. After some experimentations I have got buffer from 24RF08(8pins) in HEX(software takes dump only in hex):

Code:

:1000000076078CD80BC27405B82F25CD211F068E1C
:100010000618D3B449CD210758B44CCD218EC21F48

:10013000D400460206458680D40033DBE86B005FBE
... etc

While getting a lot of info about password decrypting, I found that password locates in that string:
Code:

:10003000000758B431CD21C60671E102BA73E1C69A

The second part of the string contains passwords as keyboard scancodes:
10003000000758B431CD21C60671E102BA73E1C69A
OK, if 06 is "5", than what is 71?
Maybe there is a way to convert from hex(this one) to bin(that one, which is used in i2c-COM programmers), so I would be free from building another interface? Any other suggestions?

Thanks a lot in advance.

The content here is all garbage. Take my advice and build a circuit to read with R24RF08, don't waste your time and nerves on this.

cheers
