The UNIVAC 1105 was a mainframe computer introduced by the UNIVAC Division of Sperry Rand in 1958. Its circuitry included vacuum tubes, diodes, and transistors. In addition to magnetic core planes like this one, its memory included one or more magnetic drums. This core plane stores 4096 words. A mark on the object reads: Part 92856 (/) Ser. 10086.
