This is a black and white 35mm image of three men working on the PDP-1. All the men are wearing white shirts and crouching down. None of them are looking at the camera. It looks like they are repairing or modifying the PDP-1. The man on the right is touching the circuit boards on the PDP-1 itself. Written on the top of the negative is "4117 Roll". Numbered at the bottom of the negative is "3" and "3A" as part of the numbering sequence of the negative roll.
