I can see only one 8-pin IC in your photo.
The one that's printed with [MXIC].

Dear All,

After I managed to unlock the password, I discover I have broken a little chip and lost it and the Imac now does not turn on. I will post the image with this chip. Can you help me to identify and maybe try to buy a new one. I have the Imac schematic diagram but for me it is Sanskrit. Thank you very much. Luigi
