Sorry for the bad quality.
My grandfather had this in his office. He worked as a computer engineer so I initally thought it was a zoomed-in picture of a computer chip or something, but maybe it is something large.
He’s not alive anymore so I can’t ask him. If somebody can help me out, that would be great.
That reminds me of the internals of the Apollo Guidance Computer. Not sure though.

It definitely does remind him.
