This is a black and white 35mm slide image of women working on the PDP-1. It looks like they are either assembling or repairing the systems. There are two women pictured each assembling or repairing a different PDP-1. None of them are facing the camera. Light is coming from the ceiling. Written on the plastic slide top edge in pencil is "PDP-1 Line P981". There are other pencil marks on the bottom edge but it is unreadable.
