Hello Great Master,
600 is using 24c01 that is a classic eeprom.
http://www.allservice.ro/forum/viewtopic.php?t=149&highlight=24c01
I have in progress a small aplication to help a forum user that has problems reading his Thinkpad's 24c01. I will post it here when I'll finish it, in a cuple of days. |

TP 600 has a low SMbus impedance, but you can try the SIPROG. Anyway SIPROG works perfect with the 24c01, only that some laptops use pull-up resistors that have smaller values.
I can't understand why you can't find the Max232 in Portugal, in my neighbourhood are 3 shops in 2 Km area that sell them. |
