I had this problem too. My reset switch was not stuck. My ROM's were fried
(according to the repairman at the dealer). It cost $84 apiece for 2 new
ROM's, plus $50 labor, to fix. The repairman said that the failure was
probably not caused by overheating. I didn't have a fan then, I do now.
I bought my Mac+ May '86. He said that it was probably caused by a glitch
in the line power, but when I told him I had a surge protector, he said he
didn't know why it happened. "Sometimes they just go bad".
