(Hartford, CT): by the Author, 1978. First Edition. Exposition of Sondheim's early explorations into computer programming, Marxist dialectics, and aesthetics, illustrated with a number of his early works produced using Assembly Language on the TI-59 calculator. Sondheim, a poet, conceptual artist and experimental musician, has established himself as a leading theorist of cyberspace; since 1994 his major ongoing work has been an extended on-line piece titled "Internet Text," a continuous meditation on "philosophy, psychology, language, body, and virtuality." These meditations can properly be said to have begun with the early experiments communicated in the present work, which is decidedly scarce. Side-stapled self-wraps; printed xerographically on standard white photocopy paper; 37 leaves. Mild discoloration to margins of cover leaf, else Near Fine.
