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.
Totally agree about the solder spots on the right and the lower middle. I think this is some sort of IC or crude, early processor. These lines would feed in/out power and data and in the proceeding decades, have been shrunk down to be contained entirely inside the processor with nothing more than pins sticking out the bottom.
