I've got an old Mac Plus that seems to be compleatly dead. It used to work OK, but I havend had it switched on for years. When I switched it on recently, absolutely nothing happened! There seems to be absolutley no power grtting into it atoll. This is one of the old Macs that take a double A battery that fits into a slot in the rear of the machine, I've replaced it, on the off chance that it would make a difference, it didn't. I also know the power lead works as I used the same one that I use for a VGA monitor. I suspect something has went on the power board, is there anything that can easily be checked, and replaced. Or should I just chuck it?
