A is High Peripheral at best. B has the gold fingers but no IC population. B is High Peripheral.
Here to learn like everybody else
My evaluations are my own opinion

Sorry. When I see a DIP which is yellow. I discount it. That 4n25 is an opto coupler. It's not a real IC in my world. But. Yes. It is labeled on the circuit board. IC. I don't see it having the same scrap value as a conventional die chip. That's my " hang up". It's the e- scrap world I have to adjust to. Many yellow DIPS are just resistor packs also.

I sent 100s of undyed ceramic IC's as IC scap to board sort... there several black ICs on the board too.
