The UNIVAC II was an improved successor to the UNIVAC I, first delivered by the UNIVAC division of Sperry Rand in 1958. Its improvements included expanding core memory from 2,000 to 10,000 words, UNISERVO II tape drives able to use either the older UNIVAC I metal tapes or newer PET tapes, and some transistorized circuits, while remaining fully compatible with existing UNIVAC I programs for both code and data; the machine weighed about 16,000 pounds.
