A memory board from the space shuttle computer, which was a stripped-down clone of an IBM 360 mainframe. The systems originally used core memory since that was resistant to cosmic rays. This is one of the solid state ram boards from the 1990 upgrade that finally replaced the core memory. There seem to be 656 kilobytes here, presumably a 512k board with a LOT of error correction?
