Anyway, we seem to have become obsessed about PROMs and EPROMs when you have already established that the four main ones in your PET are OK and even that wounded optional one has been massaged back to life.

You'll be using the CPU you borrowed from the VIC for now, but how are you getting on with finding a replacement 6520 / 6521?
