Interesting footnote to that question, John Spencer actually scored the first ever maximum in competition play in 1979 at the televised Holsten Lager tournament, unfortunately for him the camera crew were on their rest break and missed the frame. Ironically, Spencer was Steve Davis's opponent when he made his televised maximum three years later...
