Most people can simply ignore
the 93C46 EEPROM, it is only found in a few really old TP models
The most common EEPROMS used to store
passwords in TPs are LSI, 24RF08, 24C01 and very rarely 24C03. These
EEPROMS can be read without unsoldering them from the system board and normally
require only 3 connections GND, SCL and SDA.
Those 3 connections points are clearly labelled
on the KM7
The 93C46 EEPROM is very different, it
needs 6 connections and it MUST be unsoldered from the board in order to
recover the password stored in it.
ONLY unsolder a 93C46 if you have;
-
The right Surface Mount Device (SMD)
unsoldering/soldering tools
-
You have experience at using those
tools properly.
If in any doubt about about your ability to
unsolder a SMD 93C46 - I suggest you don't do it, rather have someone else
who does this for a living do it for you.
If you cheerfully go ahead and you don't
know what you are doing and lack the tools and skills required, you will
simply ruin the System Board and EEPROM
The following information is for those possessing
the right tools and skills.
