There are two images, with a slightly different angle, and two different exposures each, of some kind of what appears to be a test setup with a large label, "ABSTRAC.", on a power supply, which is on top of a Memory Buffer 2306. There are many wires between the 2306 and ten panels, in two stacks, containing a full complement of laboratory modules. Three of them have B4, B8 and B3 handwritten on a visible side plate. Above them is a power supply 726 with B-56 handwritten on it. There is a second inner envelope with the negatives and the word "Overs" on it.
