CPU now boots. I had to test CPU, Ram and PIAs so they are now socketed which will make any future repairs easier.
While i have the board i will replace the Button Battery with a Button Battery holder and new Battery.

Thankyou very much Andy for keeping me informed... Have I really done an expensive disaster on this? or has it been really easy fix so far?.

I'm just concerned I did  a lot of damage as it has really upset me on what I did
