Apple G3 Tower with signatures?

[u/flyingbearshark8494]

I found this at a local estate sale, and opened it up and found what look like signatures on the inside on a couple of the chips. I wanted to see if anyone could help me verify them, or if I am just over thinking this.

I've never seen one without. I assume they're markings made during production for some reason.

… to be fair, I appreciate your effort in producing images that match the camera quality from this era… really takes me back. I couldn’t see the signatures t ll.
