This is a vintage 1960s Univac C-111 Computer Core Memory Plane. Part number 4025527. Each piece is 5" square. This came from an estate where the previous owner had tons of early computing stuff. We have sold several of these memory planes, all to happy customers with positive response.

We have seven of this model listed with a buy it now price for each individual piece. All are identical numbers and condition, with slight variations in wires soldered at corners.

If you buy multiples we will combine shipping costs as best we can.
