    Default i need help with eeprom rcd 310

    hello friends i want to read eeprom rcd 310 i search on the pcb but i cannot find the right chip to read eeprom.
    on the pcb i see 2 chips wich i think one of them schould be the chip to read eeprom but i cannot identify which serie it is.
    one chip is 128wr st k941p
    the other one is k410 st z947
    the second chip is so small that i even cannot put a clip on it.
    chip 1 dos not have a dot to identify pin 1.

    For code you need to read eeprom ST95128 and NEC processor.

    Open the software and look if eeprom 95128 is supported by your programmer.
    It is recommended that you desolder eeprom from the board.
    For reading NEC processor you can use any USB-to-serial converter.
    Look here
