Does anyone know much about the old Mac SE? I am trying to connect a newish HDD from my Performa 6110CD (which is a Quantum ProDrive 250MB) but the computer doesn't really turn on with it connected. It makes a buzzing sound from the speaker and it sits on a black screen. Is there a compatibility issue with the hard drive and computer or is there a size limitation on the motherboard of the SE. I am trying to put a hard drive into the SE because the original has bad sectors. Any help would be appreciated.
