Neat lot of 1960s Circuit Boards
First is a Univac Board that measures 4 3/4" x 6"This was a spare that was tested to be defective,with notes on what work was done to try to get it to work.
Next are nine smaller 3C compute boards. Neat components on these and colored thick handles. Haven't seen and don't have any more of these. Measure 2 5/8" x 4"
