For a while I worked at what was then the Sperry Rand Corporation (now Unisys) which had some pride in their heritage as the descendant of the Univac Corporation founded by ENIAC inventors Eckert and Mauchly. In a glass case there was a vacuum tube circuit said to be a memory unit of the original ENIAC. No one seemed to know much about it, casting doubt on the claimed provenance of the device.

The tube circuit resembled the ones shown in the photo linked below (although none of those in the photo are from ENIAC).
