The control panel for the pye Mk5 is one of it's most attractive features.
There seems to be a knob for everything! The panel is made of Perspex
and is edge lit with all the labels glowing gently in the dark. There
was also an Operational Control Panel with just the controls for Iris
and Lift (black level). The iris control was a quadrant lever operated
by moving it towards or away, on the same knob was the lift control,
operated by rotation. This highly successful ergonomic arrangement is
still in use today!
