Description

High Quality Content by WIKIPEDIA articles! The HP 3000 series is a family of minicomputers released by Hewlett-Packard in 1973. It was designed to be the first minicomputer delivered with a full featured operating system with time-sharing. The first models were withdrawn from the market until speed improvements could be made. It ultimately became known as a reliable and powerful business system. Early models had large cabinets with front panels, while later models were made that fit into desks using only terminal consoles for diagnostics, with bootstrap routines in ROM. Models ranged from a system sometimes used by a single user, to models that supported over two thousand users. It was one of the last proprietary minicomputer systems to be retired by its vendor, outlasting the PDP-11-descended Digital Equipment Corporation VAX, which was acquired by Compaq and then ultimately by Hewlett Packard. After almost 30 years, a five-year phase-out period for the now-named e3000 series servers was announced in November 2001. HP extended this period twice. No more new e3000s are being sold, although used systems continue to be sold for upgrades on a third-party reseller market.
