So, I have an Apple ][+. It is missing an IC at location a3 on the motherboard.
I don't know why. it used to work... I think my mind is going. I have no memory or removing it. Anyway, I need another one. The board is marked 74166. Can I put any shift register IC with a similar part no, like this one: 74166PC | FAIRCHILD | IC DIP-16 Shift Register (icompplus.com) <https://www.icompplus.com/en/integrated-circuits/24400/74166PC> in there, or ?
