The Difference Engine
NY, Bantam, (1991). The advance reading copy of this collaborative novel by two of the leading writers of contemporary science fiction, both associated with the "cyberpunk" movement in the field. This is a fantasy based on the premise that the computer age started in the 1850's, rather than the 1950's, with the perfection of Charles Babbage's Analytical Engine. Fine in wrappers.
