Hello,

I have a fanuc OT-A from 1985, it works perfectly however i must save the ladder from the eeproms as i am worried that i will lose the ladder in case of a failure, it will be impossible to find data for this machine, so i must back it up.

Does anyone know how i can read the chips, ive heard any chip reader will work, but i am worried about the voltages that the programmer puts into the eeprom, im not sure, and if possible i would like some advice from the kind people here.

i am in the uk, so if you have any suggestions of which programmer i could buy here, i would appreciate it.

the eeprom is a "MBM2764-25"

Best regards
