A little more progress - socket removed. I'd forgotten how easy it was to desolder these old through hole boards - everything these says is smd and the tracks are thous wide. Think I'll leave the track checking until tomorrow.
Any hints and tips are still very welcome.
Mike.
Edit, the errors I was getting started becoming more and more random. I figured bad connection somewhere and then spotted the damage. Hopefully restoring the PCB to working order should sort it out. will keep you all posted.
