Hello, I have the Black Macbook 13" (from mid 2007). Model A1181. I think it was the 2.16Ghz, 160GB. OSX 10.4. I need help finding what Logic boards work with my Mac. Mine is broken and I need to replace. I will be looking at used or at least ones on ebay to minimize the cost. From the research that I have done. It looks like I can used any of the following: 661-5033 2.4GHz 661-4397 2.16GHz Black 661-4220 2.0 GHz black Just want confirmation please. Thank you *update* Upon further review I believe that I have found the Logic Board number. On the board itself it lists 820-1889-A?? Sound correct. I do get hits when I google it. I guess my question is what is interchangeable with this?
