I have a 27C256B with a copy protection socket. From what I read in other forums, this eeprom can be read - but its not so easy. If ECU is reading a single adress from EEPROM it switches CS (chipselect) every time. If I want to read with programmer, chipselect is always set tpo on... This is noticed by the little extra IC on the socket and it returns only crap data... So I need to write a skript for my willem Programmer to switch CS after reading an adress... But I dont know how... someone does?
