Thanks neil - that helps me a lot. I will try assembling a circuit tomorrow to get it working.
Taken your advice and re-read the whole of the thread - embarrased now - should have done that first as I had forgotten some of the postings and not realised what I was missing. That will teach me to try to go from memory!
