I've got a Williams System 3/4 MPU layout, but I don't have a Bill of Material. If you have one, what is the capacitor rating for locations C65 & C67 on the MPU board, please? Also, how do you identify positive and negative on those tiny capacitors?

C 65 .01mfd 50v

c 67 .1mfd 50v

and both leads are the same "non polarized"
