Original vintage Digital Equipment Corporation Flip-Chip PDP core memory stack pcb, with two layers of board and 8192 actual tiny magnetic doughnuts for memory. This is an 8K ram board, I believe from a PDP-8. These boards were very delicate, and this one is not functional, but it is a good collector's item, as the cores themselves are visible on the inside layer.
