In the past, I needed to read content of EEPROM, which was signed 25160. All of programmers for me available, even declared as compatible with 25160 chip, were unable correctly read this device, so I did my own one. Because it was in time of windows ME, nowadays the function of utility could be complicated due to issues with LPT driving, but there are many possibilities for old software to communicate with LPT port in newer operating systems. Scheme of connection to EEPROM is at following picture:

And here is program to EEPROM reading (vcl50.bpl is packed with it): 25160_reader.zip
