The HP 3000 is a series of minicomputers developed by Hewlett-Packard in the early 1970s. Designed primarily for business applications, it featured a proprietary operating system called MPE (Multi-Programming Executive) and supported various programming languages, including COBOL and FORTRAN. The HP 3000 was known for its reliability and scalability, making it popular among medium to large enterprises. Over the years, the HP 3000 evolved through several models, with enhancements in processing power and storage capabilities. It played a significant role in the development of business computing and was widely used until the early 2000s, when many organizations transitioned to newer systems.
