I took these pics to post here to ask about gold caps but I think I answered my question...

I ran the MC68LC040RC25A on the chip and got a gold capped chip result on digi-key's website and 486's are always(???) gold capped so I'm thinking both are gold capped chip boards.

So If I run into similar boards but can't identify a chip, is there a way to determine if the bottom has a gold cap without removing it? Like, drill a small hole from the other side of the board? Any other thoughts?

Ignore the batteries I see them :D

High Telecom on those.

Drilling hole wont help. The board will be what it will be.

You could attempt to desolder but the pins would need to be clean of solder and flux. Then the board would be devalued hard.

I just meant a hole to be able to see the the underside of the chip to confirm whether the chips do or do not have a gold cap when I can't find anything definite identification on the chip. I'd imagine that wouldn't irreparably damage the board's grade but wanted to check.
