There is a Pat. No 3793483 on the board which is a Bushnell patent so I am assuming this is Atari. Copyright date of 1974. Other markings are RT20-B and the board has the numbers 001791 on the part side and 001792 on the solder side. I don't have a camera to take a picture but it looks like similar Atari PCB's of the same time period.
