Everything you ever wanted to know about HP’s 9000 Series 300

Hewlett-Packard’s 9000 Series 300 (HP300) was a range of technical workstations based on Motorola 680×0 microprocessors. Superbly engineered in modular form, and ahead of the curve in terms of functionality, these workstations were used mainly as instrument controllers and for desktop technical computing. The HP300 series launched in 1985 with the models 310 (pictured below) and 320. It evolved through numerous variants of increasing power, concluding with the 38x models released in 1991. The series was officially obsolete as of 1997.
