It started with the computer not being able to boot past the grey apple.

After a lot of investigation it's determined that a motherboard is damaged.

I have taked a picture: http://donfirth.com/mdd

As you can see the 3 yellow square.

1 of them have blown.


I have a question as to the likeliness of the CPU's still being fine.

I would imagine they are since it still boots to the grey apple and target disc mode functions.


Can I use slightly different models of the MDD motherboard.

Mine is a 630-4633 and my CPU's are dual 1.25 GHz.


Thanks for any help.
