RCA 630TS - Modified with Motor

[maxm]

The wafer switch seen under the chassis is connected to the black knob on the rear, which is labeled "Video Sync", "Video", and "Normal". All of the black cables appear to have been added for the color wheel operation. Several connect to the connectors on the rear of the chassis and some enter the small additional "project box" chassis, which I haven't opened yet. I will try to remove the chassis in the future and take some additional detailed photos of the added wiring so this information can be preserved.

I was told at the sale this set was purchased from that the owner had worked for the IIT Research Institute in Chicago. Based on other items he had built that were at the sale and the collection of literature he owned it appears he had been quite knowledgeable about electronics.
