Prior to this the layout of PCBs had involved large sheets of paper and lots of sticky black tape! |

A comment from Roger on 29/12/04: "I hotly dispute the claim that we were
still using large sheets of paper and black sticky tape. This was the middle
80s for god's sake and by then I had changed it to red tape only, I know
that to be true as I am still finding bits of it stuck to my elbows".
