content: During the late 1950s and early 1960s, the Great Valley Laboratory of Burroughs Corporation developed a series of experimental computer memory components of which these are samples assigned museum numbers 1987.0882.01.01 through 1987.0882.11. the specific objects (all of which are flat and rectangular) may be described as follows:
label: Description
content: .01.01 - a glass memory plane, 10.2 cm. x 8.3 cm., with 160 metal rectangles, arranged in a 20x8 array.
label: Description
content: .01.02 - a greenish memory plane, 10.2 cm. x 8.3 cm., with two sets of stripes that intersect perpendicularly. One side has a sticker on it that reads: Film Side.
label: Description
content: .01.03 - a thinner greenish memory plane, 10.2 cm. x 8.3 cm., again with two sets of stripes that intersect perpendicularly. It has two indeciherable marks in red.
