Sorry not to have got back, one of my dogs became sick, needed 24 hour care, but subsequently it became terminal and he had to be put to sleep.
I really appreciate all the help, sadly I did not have the required software nor experience to do this conversion myself, but frozenfrogz very kindly did me some mirror .pdf images for a few beers and hopefully I can now recreate my boards. I have had issues with some photo resist board that's been in a drawer for over a year, so have ordered new PCB and will try again, the help here has been exceptionally generous, thank you all.
