In 1963 I purchased the assembly manual and schematic for the Colordaptor, which included samples of the color filter material. The setup included a ten tube chassis. If memory serves, a kit of parts which included a pre-punched chassis, but not the color wheel or motor, was about $250. For a completely assembled and tested unit, which included the color wheel and motor, the price was around $400. The following year, you could purchase a Heathkit 21" round tube set in kit form for about $395. Needless to say, I never bought the Colordaptor! I eventually discarded the manual and schematic. I wish I had them now.
