Los Alamos Direct Colour Output (1975)

In 1975 Los Alamos had two FR80s and two SC4020s. One of the SC4020 systems was Serial No 3 and was the earliest SC4020 still running. Both FR80s and one SC4020 had white phosphor tubes and a colour wheel with primary and secondary filters allowing colour film to be produced directly on the microfilm recorder as shown by this example.
