searching for an error in my A3000T that fails to boot (grey screen) and sometimes ended with a yellow screen and it seemed to be a defective SCSI-controler chip. After replacing it with a newer revision, the A3000T works again.
I'll have to give my A3000T another once over with this info. Mine died last week with the same symtoms.
Of course, Amiga death only happens when you really need the system to do something besides take up space and consume power... :nervous:
