CBS Color Personal Viewer
This viewer came from the estate of John Christiansen, a CBS engineer. It was designed to be placed on a table where a person could look through the opening at a black and white set some distance away. With this arrangement, a set of any screen size could be used.
We don't know if this was for laboratory testing, or if it was a prototype of a unit to be sold to the public. The knob on the rear is a motor speed control, and there is apparently no synchronization. The operator would adjust the knob until the proper colors appeared, and would have to constantly re-adjust it to keep the colors right.
We plan to modify the Bendix 235MI set in our collection to operate with CBS field sequential video, and use it with the personal viewer.
