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.

Would anyone like a free subscription (for one month) to the Expanding Dan, the fantastic Steely Dan newsletter? It seems I've got two left to give away.

Subscribers can access the archive, so for instance you can read the complete interview with the technician who erased the Second Arrangement tape: https://expandingdan.substack.com/p/steely-dan-second-arrangement-erased-interview
